Every one of our innovative boiling water taps comes equipped with a boiler tank, filter and all of the fittings and pipes required for installation. Though boiler tanks come in a wide range of sizes and shapes, we find our 2.4-litre tanks are the perfect fit for the modern kitchen. The exact dimensions of our boiler are:

Height - 295mm

Width - 184mm

Depth - 184mm

boiler tank and filter

This makes our boiling water taps suitable for kitchens of all sizes. Our boiler tanks will dispense 5-6 cups of piping-hot water at a time, enough to fill pans, mugs and hot water bottles with ease. What's more, your tank will reheat in just 4 minutes, which means you'll never be without boiling water whenever it's needed.

As an extra bonus, all of our boiler tanks feature a touch screen that allows you to adjust the temperature to between 75°C and 98°C, which means you can brew the perfect cup of tea or coffee every time. The touch screen also monitors the health of your boiling water tap, displaying a red light every 6 months when it's time to replace the filter.

What's more, our filters are designed to keep your tank free from limescale and ensure that only pure boiling water is released with each turn of the tap. This helps to maintain the longevity of your boiler by preventing limescale and other mineral deposits, which may have otherwise damaged your tank's performance over time. Our 4-in-1 taps come with an upgraded filter that also filters the cold water line, providing crystal-clear drinking water for you and your family.

Boiling water taps (also called 'instant hot water taps') are fast becoming the must-have appliance in British kitchens, offering next-level convenience for homeowners. If you're thinking of buying one for your kitchen, in this guide we hope to answer your most-asked questions about the costs, benefits and more.

What is a boiling water tap, and how do boiling water taps work?

A boiling water tap (sometimes called a '3-in-1' or '4-in-1' tap) offers instant boiling water at the turn of a handle. To do this, a boiler tank is fitted under your sink that maintains a supply of water at a boiling hot temperature, ready to be used whenever required.

The majority of boiling taps come with a filter for the boiling water, which removes impurities and carbon. The majority of boiling water taps will fit to your mains supply, giving you hot, cold and boiling water from a single spout, however, there are some models that only dispense boiling water, which means you will need to keep your mains-supplied tap for regular hot and cold.

Types of boiling water tap

There are generally four types of boiling water tap:

  • Boiling-only taps only dispense boiling water, which means you will need to keep your other tap for regular hot and cold water
  • 3-in-1 taps dispense regular hot and cold water, along with filtered boiling water
  • 4-in-1 taps dispense regular hot and cold water, filtered boiling water and filtered cold water
  • Flex taps can be 3-in-1 or 4-in-1, but they always have a pull-out spout

The benefits of boiling water taps

There's a reason for boiling water taps becoming as popular as they are:

  • They are incredibly convenient for everyday cooking and cleaning jobs, like brewing hot drinks, cooking pasta, noodles or vegetables, mopping your floors or filling up hot water bottles
  • They'll cut down on time wasted waiting for your pan or kettle to boil
  • They look great and are available in a wide range of finishes and styles, ideal for the vast majority of kitchen interiors
  • They are affordable to run and straightforward to install
  • You only use the boiling water you need, cutting down on the energy waste that comes with boiling a kettle

How much does a boiling water tap cost?

Previously, a boiling water tap could cost upwards of £1,000+, depending on which brand and model you chose, and the upgrades you tagged on. While some taps can still cost upwards of £1,000, at Hot Water Taps, the price for our Avista 3-in-1 tap is just £299. This means it's more affordable than ever to own a boiling tap at home.

4-in-1 taps cost more than 3-in-1 taps, thanks to the cold water filter, while flex taps vary but are generally more costly than a basic 3-in-1 tap. If you need to hire a plumber to fit your tap, it may cost between £50 and £100, depending on the complexity of the job and tap model. We recommend you change your filter every 6 months to ensure it's running efficiently - ours cost just £29.95, though other brands may vary.

Running costs of a boiling water tap

Many people mistakenly assume a boiling water tap is expensive to run, but they are designed to run extremely efficiently.

An insulated boiler tank means minimal energy is required to maintain the water supply at a high temperature, costing between 10 and 15p a day. Comparatively, a kettle can cost anywhere from 2-6p to boil each time, depending on the make and the amount of water. This means that if you boil a kettle multiple times a day, you're unlikely to see much difference in your energy bills.

Boiling water taps - are they safe?

Parents might have concerns about whether a boiling water tap is safe to have around children. The truth is that brands have incorporated safety mechanisms into their taps, preventing the boiling water function from being accessed by children. Our taps have a spring-loaded mechanism which means the boiling function will turn off if not supervised, while the spout is insulated, preventing its surface from becoming too hot.

Kettles, on the other hand, can be dangerous if handled incorrectly. For example, an elderly person may drop or spill a kettle accidentally, or a child might tip the kettle over by mistake. Plus, water may splutter when coming out of the kettle's spout.

WRAS-approved products

To ensure your new tap has passed safety regulations, we recommend looking for WRAS-approved products. The Water Regulations Approval Scheme is an independent UK certification body, who independently test products like boiling water taps to ensure they're safe for the public.

Installing a boiling water tap

Installation is pretty straightforward, though sometimes a plumber is needed if you're inexperienced. To install a boiling water tap, you will need to fit the boiler tank and filter in your kitchen cabinet, requiring a plug socket and basic electrical and/or plumbing knowledge.

Boiler tanks

Boiler tanks range in size from 2 to 7 litres, so it's worth checking the dimensions to see how much space you have available in your cupboard. Our boiler tanks are 2.4 litres, dispensing 6-7 cups of instant boiling water a time. Because the tank only takes 4 minutes to reheat, it's not usually necessary to choose a bigger boiler tank than that.

Water pressure

The operating water pressure of our taps is between 0.5 to 5.0 bar, though this may vary for other brands, so bear this in mind before installation. If your water pressure is too low, you should speak to a plumber before ordering and installing your boiling water tap.


The process is generally hassle-free, and you are often covered by warranty should their be a defect with the product. We are proud to offer one of the longest warranties on the market, with 2 years for your tank and 5 years for your tap. It is important that you check the conditions for your warranty to ensure you meet any specific requirements, such as changing your filter regularly.

Maintaining an instant boiling water tap

Maintenance is pretty straightforward, requiring regular cleaning just like any other tap. This can be done with a gentle soapy mixture and doesn't require a special cleaner. As it's an electrical appliance, it should be inspected once a month for leaks or defects, particularly around the boiler tank and filter.

Should I turn my boiling water tap off at night?

We don't recommend turning your boiling water tap off at night, as it will consume more energy reheating than by simply leaving it on. If it will be unused for over a week (for example, if you are going away on holiday), you can switch it off at the socket to preserve energy, draining and refilling it when you return.

Do boiling water taps heat to 100°C?

Most taps on the market don't dispense 100°C, instead dispensing water that is a couple of degrees cooler. This accounts for heat loss when the water is ran through the spout. However, this makes little difference when it comes to cooking and cleaning; in fact many hot drinks like tea and coffee should be brewed below 100°C, and a cold steel saucepan will sap a few degrees of heat from boiling water on contact anyway.

Which boiling water tap should I buy?

We have four models, which each come with a variety of different spout styles and colours, including black, gold and copper. Our models are:

  • Avista - our most affordable 3-in-1 tap
  • Athena - our premium 3-in-1 tap
  • Quantum - our best-selling 4-in-1 tap
  • Platinum - our 4-in-1 tap with a pull-spout

With the launch of our affordable range of boiling water taps, more homeowners than ever are increasingly enjoying the convenience of a boiling water tap at home. But, despite the low price tag, installing a high-tech appliance is still an investment. Like every other appliance in your home, you want your boiling tap to withstand daily wear and tear and last as long as possible. In this article, we'll share how you should clean and maintain your new 3-in-1 or 4-in-1 kitchen tap.

Cleaning your boiling tap

To keep your boiling water tap looking its best every day, you should wipe it dry after use. To do this, you could use the soft side of a sponge, a microfibre cloth, a tea towel or kitchen roll. At least once a week, use a drop or two of washing-up liquid (any brand will do) and, using a soft sponge, lather the tap from its base to the end using warm water.  We highly recommend you don't use scourers or abrasive sponges - they may damage the finish on your tap. Finally, rinse the soap off with warm (not boiling) water and dry with a microfibre cloth or a soft tea towel.

Top tip: be careful not to push the boiling tap spring-lock in as you are cleaning

diluted lemon solution in a spray bottle

On a bi-weekly or monthly basis, you can use diluted lemon juice to return natural vigour and shine to your tap. Simply dilute lemon juice by 1:4 with water, pop it into a spray bottle and apply it to your tap, leave for a minute and wipe it off with warm water before buffing and drying it with a soft cloth.

Top tip: don't use bleach or harsh chemical cleaners - they may ruin the finish on your tap and/or sink

What about the boiling water tank?

The 2.4l tank requires little maintenance. We simply recommend you check on a monthly basis to ensure there are no visible signs of wear, tear or leaks. If you spot a leak or damage, please turn off your boiler unit at the wall and get in touch to speak with one of our professionals. Do not continue to operate the tap if there are visible issues with the boiling water tank.

Replacing your filters

The 3-in-1 taps come with a filter for the boiler tank, which removes carbon and other impurities. The 4-in-1 taps come with an additional filter for cold, filtered water. You should replace your filter every six months to ensure they function effectively and your warranty is still covered. This is easy to do using the instructions provided, and will rarely require a professional.

Should you service a boiling water tap?

Servicing isn't necessary in the majority of cases. Regularly cleaning and checking your boiling tap will ensure you can spot potential problems and keep superficial wear and tear at bay. However, we recommend getting a professional to look at your system if you encounter issues including:

  • Water leaking from the boiler
  • Exceptionally low or high water pressure
  • Damage to the body of the boiler tank

Dealing with limescale on your tap

Thanks to the provided filter, limescale is rare on our boiling taps. However, if you live in an area with particularly hard water, you may notice limescale start to appear after some time. To remove this, dilute lemon juice 1:4 with water and spray it onto the limescale. Leave for a few minutes and then wipe (don't scrub) it off. If that doesn't work, you could try a vinegar and water solution (1:1).

Should you turn off a boiling water tap at night?

There's no need to turn your boiling water tap off at night. The boiler will sit at a consistent temperature until it's ready for use in the morning; requiring minimal amounts of energy. This is more efficient than turning your boiler off every night, as it requires more energy to reheat the entire tank.

What to do if you're going away

If your tap won't be used for 2 weeks or less, we suggest leaving it on. If you're leaving your tap for longer, you can switch it off to save power. If you think the property will drop to near-freezing temperatures while you're away, we suggest draining the unit completely, including the pipes, to prevent excess damage.

How safe is a boiling water tap?

Compared to kettles, boiling water taps are incredibly safe. Whereas kettles are hot to the touch when turned on, our boiling tap tank and spout are insulated, preventing burns. And where kettles can be picked up and dropped, a boiling water tap is fixed in place. To make our boiling taps even safer, our models all include a spring-loaded mechanism, which will prevent the boiling water from accidentally being switched on.

What is the difference between a 3-in-1 and a 4-in-1 tap?

While both types of tap dispense instant boiling water, the 4-in-1 tap dispenses cold, filtered water, too. The filter that arrives with the 3-in-1 tap is for the boiler tank only. For families who want to drink pure h2o from the tap every time, a 4-in-1 tap is a perfect fit. If convenience is

What is a flex tap?

A flex tap has a flexible hose, which can be removed and used to direct the flow of water around your kitchen sink. This is incredibly useful for getting to different parts of your sink, whether you are cleaning dishes or filling a glass with crystal-clear drinking water.

Which boiling tap is best for me?

How energy efficient are boiling water taps?

Boiling water taps are shown to be more energy-efficient than kettles, often costing the same to run for a full day that a kettle would use in just a couple of boils. What's more, because you're not boiling water you don't use, you'll prevent unnecessary energy waste, saving you money in the long run if you're an avid coffee or tea drinker. Overall, a boiling water tap will make little difference to your energy bill, which means those concerned about additional running costs need not worry.

If you're a homeowner, sooner or later you'll need to know how to change a kitchen tap. It's not a difficult job, but it can be tricky if you're not used to working with plumbing. In this blog post, we'll walk you through the process step-by-step so that you can easily get the job done without any trouble. Sooner or later, every homeowner will need to know how to do this!

Tools you need to change a kitchen tap

When it comes to making repairs or modifications to your kitchen, a few key tools are essential. The first is a set of adjustable wrenches, which allow you to easily grip and turn the various nuts and bolts that hold your tap in place. A good quality plier set is also important, as these will help you to reach the more inaccessible parts of the tap.


Other useful tools include a pipe cutter and an adjustable tap wrench, both of which are useful for cutting through soft copper tubing associated with older taps. Finally, if you need to completely remove the tap from your kitchen sink for any reason, a heavy-duty basin wrench will be invaluable for getting it out safely and easily. With these tools in hand, anyone can successfully replace or modify their kitchen tap in no time at all!

How to remove an old kitchen tap

Removing an old kitchen tap can be a difficult and time-consuming process, especially if you want to do it yourself. One of the most important things to keep in mind is that old taps often have corroded fittings, which means that you will need to take extra care during the removal process.

You should first shut off the water supply so that you can safely remove any hoses or pipes without risking any leaks. Once the pipes and hoses are removed, disconnect the faucet from its mounting bracket using an adjustable wrench. Finally, you can use a pipe wrench to carefully loosen and remove the faucet itself. With these steps in mind, you can successfully remove an old kitchen tap and prepare your sink for a new, more modern fixture.

Things to consider before installing a new tap

When it comes to renovating your kitchen, upgrading your tap is one of the easiest ways to give your home a quick and easy facelift. Whether you are looking for a sleek modern design or a vintage classic look, there are endless options to choose from when it comes to kitchen taps. However, installing a new kitchen tap can be tricky, especially if you have never done it before. Here are some tips that will help you fit your new faucet and make sure that it works properly and looks great in your kitchen.

  1. Choose the right size and shape. One of the most important considerations when installing a new kitchen tap is making sure that you select the right size and shape for your sink. Consult your manufacturer's specifications to ensure that you get the right measurements, and always measure twice before cutting any pipes or fittings.
  2. Test for leaks. Once the new tap is fitted, make sure to test it for leaks before using it regularly. A leaky faucet can waste water and cause damage over time, so be sure to check all connections and tighten them as necessary before putting your tap into service.
  3. Keep it clean! Lastly, one of the best ways to keep your tap looking great is by keeping it well-maintained with regular cleaning and care. Use gentle cleansers and soft cloths when washing down your faucet to avoid damaging silicone seals or gaskets, and consider investing in a spray attachment to make cleaning easier in hard-to-reach areas like underneath sinks or behind taps. With these simple tips in mind, you can rest assured that your brand-new kitchen tap will be shining brightly for years to come.

How to install a new tap

  1. Use a tape measure to get accurate measurements of the holes in your sink, as well as the distance between them. This will ensure that you purchase a tap that fits perfectly in your sink.
  2. Before starting any installation, always shut off the water supply to avoid any accidents.
  3. Use a basin wrench to remove the old tap if necessary.
  4. Apply a layer of plumber's putty around the base of the new tap.
  5. Insert the new tap into the holes in your sink and hand-tighten the mounting nuts.
  6. Use a wrench to finish tightening the mounting nuts, being careful not to overtighten them.
  7. Reconnect any hoses or pipes and turn on the water supply.
  8. Test your new tap for leaks and enjoy!

Common problems when replacing a tap

When trying to replace a tap, several common issues can arise. For example, many people struggle with correctly attaching the tap to the water pipe leading into the sink. If the tap is not securely tightened, it can allow water to leak out, causing a waste of precious resources as well as frustration and a mess on your hands.

Additionally, it is important to ensure that proper pipe fittings and connections are used to avoid having problems with pressure or leaks down the road.

Another common problem when replacing a tap is poor water flow from the tap. This may be due to sediment or mineral buildup in the tap itself or simply from an incorrectly sized tap for your sink. Luckily, there are many solutions for improving water flow, including changing tap accessories like aerators or installing larger pipes leading into your tap. With some tap troubleshooting and careful consideration of different factors involved in tap replacement, you can enjoy years of hassle-free use from your new tap!

Are boiling water taps easy to install?


While many people may be sceptical about the installation of boiling water taps, these devices are quite easy to set up. In general, installation simply requires attaching the tap to your existing water line and plugging it in. No extensive plumbing or welding is necessary, and most installations can be done by simply following the instructions provided by the manufacturer.

Furthermore, since boiling water taps are powered entirely by electricity, there is no need to worry about installation affecting the overall flow of water in your home. Overall, whether you are a homeowner looking to take your kitchen setup to the next level or a contractor looking for an innovative product to offer clients, boiling water taps are a simple yet effective solution for installing clean, hot water on demand.


How much does it cost to replace a kitchen tap?

The cost of replacing a kitchen tap can vary depending on several different factors. At the lower end of the cost spectrum, you may be able to replace an old, worn-out tap yourself for as little as £50. However, if your existing tap needs to be moved or requires a more complex installation process, costs may be significantly higher.

Factors such as the type of tap and its associated materials will also impact the total cost. For example, a more high-end model that features sophisticated sensors or built-in filtration may cost £300 or more. Ultimately, the best way to get an accurate estimate of your kitchen tap replacement costs is to consult with a professional plumber who can evaluate your needs and provide options for achieving your desired results.

How can I change a washer on a kitchen tap?

If you are experiencing problems with your kitchen tap, the first thing to do is to determine what is causing the issue. This can often be done by simply checking your water pressure and looking for leaks around the tap. If there does seem to be an issue with the washer, you will need to replace it to restore function and keep water flowing smoothly. There are a few basic steps that you can follow to change a washer on a kitchen tap.

The first step is to locate the screws that secure the handle of your faucet to the base. Depending on your particular model, these may either be visible or require you to take off any decorative covers. Once you have removed these screws, lift or pull out the entire handle assembly of your sink so that it hangs freely below where it connects to the tap itself.

Once you have access to the tap itself, carefully unscrew any retaining clips or nuts holding together any pipes and hoses associated with your broken washer. You should then be able to remove any old washer to access your new one. Make sure that you choose a replacement washer of exactly the right size and shape for your particular model – getting this wrong could cause further leaking or other issues later on.

Finally, reassemble all components of your tap using appropriate tools and check that everything fits securely before turning on the water again. By following these simple steps, you should be able to quickly and easily replace a broken washer on your kitchen tap in no time at all!


By following the steps in this article, you can change your kitchen tap quickly and easily without any drama. Be sure to read through all of the instructions before starting so that you know what to expect. And always remember to shut off the water supply before beginning any plumbing projects!

Cooking & Drinking

Brew tea & coffee

Brewing tea and coffee is often a two-step process: first, you have to boil water, and then you have to let the water cool down to the appropriate temperature before adding it to your tea or coffee. But what if there was a way to boil water and let it cool down all in one step?

That's where a boiling water tap comes in. Boiling water taps are equipped with an adjustable boiler that lets you select the exact temperature you need for your tea or coffee. That means no more waiting for the water to boil; simply turn on the tap and adjust the boiler to your desired setting. Whether you're a tea aficionado or a coffee connoisseur, a boiling water tap is a must-have for any kitchen.

Cooking vegetables

cooking vegetables using a black frying pan

Hot water taps, also known as boiling water taps, are becoming increasingly popular in kitchens across the country. And it's no wonder why - they offer a convenient and easy way to cook vegetables. Simply place your vegetables in a pot or pan and hold them under the tap until the water reaches the desired temperature. Then let the vegetables cook until they're tender. Hot water taps are also energy-efficient since they only heat the water that you need. And cleanup is a breeze - just rinse your pot or pan under the tap when you're done. Whether you're an experienced chef or a beginner cook, a hot water tap can make cooking vegetables easier than ever.

Cooking pasta or noodles

Boiling water is an essential step in cooking pasta or noodles. The boiling water tap is a convenient way to get boiling water without having to wait for a pot of water to come to a boil on the stove. Boiling water taps are also known as hot water taps or instantaneous hot water dispensers. They are commonly found in kitchens, but can also be found in bathrooms and laundry rooms.

Boiling water taps are connected to a regular mains supply and have an under-sink boiler that maintains a constant supply of boiling water. Boiling water taps can be a great addition to any kitchen, but it is important to use them safely. Fortunately, our taps come with a child-safe mechanism that prevents children from accessing the boiling water function of the tap.

Thaw frozen foods

Hot water can be a quick and effective way to thaw frozen foods. Simply place the food in a bowl or container and run boiling water from the tap over it until it is thawed. Be sure to use hot water, as cold water will not thaw the food as quickly. Hot water can also be used to speed up the defrosting process in the refrigerator. Simply place a bowl of hot water in the refrigerator for a few minutes before adding the frozen food. The hot water will help to raise the temperature of the fridge, making it easier to thaw the food.


Sterilise baby bottles & cutting boards

Boiling water taps are becoming an increasingly popular kitchen appliance, and it's not hard to see why. Boiling water is an effective way to kill bacteria, and it can be a lot faster than waiting for a pot of water to come to a boil on the stove. A boiling water tap can also be used to sterilise baby bottles and cutting boards, making it an essential tool for any parent. With a little care and maintenance, your boiling water tap will provide years of trouble-free service.

Fill a hot water bottle

pouring hot water

Hot water bottles are a great way to keep warm during the cold winter months. However, it is important to fill them correctly to avoid burns. One way to do this is to use a hot water tap, which will prevent splutter and ensure a smooth stream into the bottle. Alternatively, pour the boiling water through a funnel for even greater accuracy. Boiling water can be dangerous, so it is important to make sure that the tap is fully turned off after filling the bottle. Once the bottle is full, screw the top on tightly and wrap it in a towel or blanket. This will help to keep the heat in and prevent burns. As we head into winter, hot water bottles are an ingenious way to stay warm during cold nights.

Kill unwanted weeds

Weeds are pesky plants that compete with our flowers and vegetables for space, water, and nutrients. While there are many herbicides available to kill weeds, boiling water is an inexpensive, effective, and environmentally friendly method. Boiling water will kill any plant it comes in contact with, so be careful not to spill it on wanted plants.

Boiling water also kills weed seeds, so it can help prevent new weeds from sprouting. To use boiling water to kill weeds, simply pour it directly on the weed leaves and roots. The boiling water will penetrate the plant's cell walls, causing the plant to die. For best results, repeat this process every few days until the weed is completely dead. Boiling water is a safe, easy way to kill unwanted weeds.

Kill mould and bacteria

There are few things more unpleasant than coming across mould or bacteria in your home. Not only do these unwelcome guests spoil the aesthetic of your space, but they can also pose a serious health risk. The good news is that there is a simple way to get rid of mould and bacteria - boiling water.

The high temperatures of boiling water are lethal to most moulds and bacteria, making it an effective way to clean and disinfect surfaces. Simply run the hot water tap until the water reaches boiling point, then use it to clean affected areas. This method is quick, easy and effective, so there's no excuse for not keeping your home free of mould and bacteria.


Is a boiling water tap safe?

Yes, boiling water taps are safe. They have a child-safe mechanism that prevents the water from coming out unless the handle is in the fully open position. This means that there is no risk of scalding yourself or your family. The tap also has a built-in filter that removes impurities from the water, making it safer to drink. In addition, the boiling water tap is more energy efficient than using a kettle, so it can help to save you money on your energy bill. Overall, the boiling water tap is a safe and convenient way to get hot water.

How expensive are boiling water taps?

When it comes to boiling water taps, there is a wide range of prices on the market. At the high end, you can find taps that cost upwards of £1000 whereas our Avista tap is only £299. In general, the price of a boiling water tap depends on a few factors, including the brand, the features, and the design. Some brands are more expensive than others, and some features, like filters or temperature controls, can add to the cost. However, boiling water taps can be a great investment for any kitchen, as they save time and energy while providing an endless supply of hot water.


A boiling water tap is a convenient and safe way to get hot water. It can also help to save you money on your energy bill.

Taps that dispense boiling water are a particularly popular choice for new builds, extensions and renovations, allowing homeowners to access piping hot water instantly, instead of waiting for the kettle or a stove-top pan to boil. But with a growing number of brands on the market, knowing which hot water tap to choose can be overwhelming.

Today, we’re saving you precious time by sharing a straightforward, side-by-side comparison of three top models: our Athena tap, the Quooker Fusion and the Franke Minerva 3-in-1.


Budgets are an unavoidable aspect of home planning, so let’s see how these taps might fit into yours. 

Tap Price (as of July 2022)
Athena From £369
Quooker Fusion From £1,150
Franke Minerva 3-in-1                        From £1,092

Of the three, the Athena tap is by far the most affordable, with the Fusion and Minerva 3-in-1 taps requiring homeowners to fork out around three times as much. If your budget is limited or you have multiple taps to buy, the Athena could be the best option for you.


If you’re passionate about creating a cohesive look throughout your home, being able to choose from a variety of different looks can be a dealbreaker. Let’s see how customisable each tap is:

Tap Finishes
Athena Swan or D Neck: Chrome, Brushed Nickel, Matt Black,

Brushed Gold or Copper 

Quooker Fusion Swan or D Neck: Polished Chome, Stainless Steel, Black,

Patinated Brass or Gold

Franke Minerva 3-in-1                         Chrome

While the Athena and Fusion taps come in 10 or 12 different looks, respectively, the Minerva 3-in-1 is available in just one shape and colour: Chrome. While chrome appliances are still popular in home design, if you want to stand out then the Minerva 3-in-1 may not be the best choice. 

It’s also worth noting that changing the appearance of the other two models from their standard ‘Chrome’ look will come at an added cost. The Quooker Fusion’s most expensive finish (Gold) will add an extra £870 to your bill. The Athena’s most expensive finishes (Matt Black, Brushed Gold or Copper) will add an extra £30 to your bill.

Boiler size

The boiler size will dictate how much hot water can be drawn at a time without the need to reheat. Let’s see how our competitors stack up:

Tap Boiler size
Athena 2.4L
Quooker Fusion 3L, 7L (+£270), COMBI (+300)
Franke Minerva 3-in-1                        5L

The biggest of the three standard tanks is the Minerva 3-in-1, which comes with a 5L, horizontal tank. The Fusion tap follows with a 3L standard tank, with the ability to upgrade to a 7L for £270. Finally, the Athena tap comes with a 2.4L tank, which is still able to deliver 5-6 cups of boiling water at a time. With only 4 minutes required for the boiler to reheat, a higher capacity tank would only be needed for a particularly large household. If that sounds like you, the Fusion or Minerva 3-in-1 taps could offer that.

Water types

A tech-savvy tap can transform your everyday cooking and cleaning, providing different types of water in an instant. Here we can look at which taps offer what:

Tap Can dispense
Athena Cold, hot, boiling (98°C)
Quooker Fusion Cold, hot, boiling (100°C) + sparkling (CUBE upgrade for £1,150)
Franke Minerva 3-in-1                        Cold, hot, boiling (100°C)

All three can dispense cold and hot water through a mixer, along with boiling water - though the Athena’s is 98°C vs the Fusion and Minerva’s 100°C. This two-degree difference is designed to prevent spitting and save energy, though some argue that water has to be 100°C to be truly ‘boiling’. Despite that, for almost every use in the kitchen, 98°C is more than hot enough. The Fusion tap can also dispense sparkling and cold filtered water with the addition of its ‘CUBE’ add-on, which will foot an extra £1,150 onto your bill. 


Coming home to a faulty tap can create unwanted stress, which is why a warranty cover is so important. All of the taps in our comparison offer a warranty, but let’s see how long:

Tap Warranty
Athena 5 years for tap, 2 years for boiler
Quooker Fusion 2 years
Franke Minerva 3-in-1                        2 years

The Fusion and Minerva 3-in-1 hot water taps come with a standard 2 years warranty. The Athena, however, extends this by three years, offering a 5-year warranty for its tap, and 2 years for the boiler. While manufacturing issues are rare these days, faults can still spring up on taps from established brands - which is why a longer warranty can offer extra peace of mind.

Today’s analysis has hopefully shed some light on the differences when it comes to boiling water taps. With more information at your fingertips, it should be easier to make an informed decision when it comes to buying.

Designing a new kitchen - or renovating an existing one - can take you on a journey through all manner of technical specifications and complex costs. It can become confusing to keep on top of everything when there are so many variables out there, but getting the right fixtures and fittings can make or break your kitchen’s form and function. 

Modern homes require a modern tap. Thankfully, taps are more sophisticated than ever, and homeowners are increasingly choosing taps that can dispense boiling water in addition to regular hot and cold water. As experts in hot water taps, we’ve made your life easier by stacking three popular models side-by-side to reveal what you should look for and how they compare.

Let’s take a closer look at our Athena tap, the Fohen Fahrenheit tap and the Grohe Red tap.


First things first: let’s talk numbers. Home renovations are often not cheap, with bills quickly racking up when it comes to tech and fittings. How do our test subjects compare?

Tap Price (as of July 2022)
Athena From £369
Fohen Fahrenheit                           From £469
Grohe Red From £1,533

It’s clear to see there is a wide range of price points when it comes to boiling water taps. At over 4x the cost of the Athena, the Grohe Red is the most costly of the bunch. The Fohen Fahrenheit is over £1,000 cheaper - though the Athena is £100 cheaper still. For homeowners who need to stick to a modest budget, it’s clear who the frontrunner would be. 


For interior design connoisseurs, picking a matching aesthetic to tie into a theme can be just as important as the function itself. Let’s see what each tap offers in terms of customisation:

Tap Finishes
Athena Swan or D Neck | Chrome, Brushed Nickel, Matt Black, Brushed Gold or Copper 
Fohen Fahrenheit           Polished Chrome, Matt Black, Brushed Gold, Unfinished Brass, Gunmetal Grey, Brushed Nickel, Polished Bronze, Champagne Gold, Polished Nickel, Titanium Gold, Silk White & Satin Pink
Grohe Red Stainless Steel

With an astounding 12 colour choices, the Fahen Fareinheit leads the pack. It includes standard kitchen colours like ‘Polished Chrome’, ‘Matt Black’ and ‘Unfinished Brass’, along with alternative options like ‘Silk White’ and the bombastically bright ‘Satin Pink’. Closely behind, the Athena tap comes in two spout shapes and 5 different colour choices - making 10 combinations in total. If the shape of the spout is important, the Athena wins out as the only tap to offer two options.

The Grohe Red falls behind on aesthetic choices, with just one: its standard ‘Steel’ look. If your home has a cohesive look that involves other metals or colours, this model may not be right for you.

Boiler size

Back to function: the size of the boiler tank dictates how much hot water can be drawn at a time - which is, of course, an important factor when choosing a hot water tap.

Tap Boiler size
Athena 2.4L
Fohen Fahrenheit                           2.4L
Grohe Red 3L, 5.5L (+£194)

Inching slightly ahead, the Grohe Red comes with a 3L tank as standard. Compared to the Athena and Fohen Fahrenheit taps, which both come with a 2.4L tank, the Grohe Red, therefore, has the capacity to dispense more boiling water without pausing to reheat. The Grohe Red also has the option of a tank upgrade, taking it from a 3L to a 5.5L at the added cost of £194. 

As capacity goes, the standard tank sizes aren’t too different from each other. A 2.4L tank will already hold enough water to dispense 5-6 cups without reheating, which takes roughly 4 minutes for the Athena model. Unless you have a household requiring large amounts of boiling water in a short space of time, a 2.4L tank is often more than big enough to handle day-to-day use.

Water types

These days, taps can come with all sorts of features to take them from basic to advanced. Take a look at what kinds of water these three tap models can dispense:

Tap Can dispense
Athena Cold, hot, boiling
Fohen Fahrenheit                           Cold, hot, boiling
Grohe Red Cold, hot, boiling

As you can see, all three taps are neck and neck, with the ability to dispense cold and hot water through a standard mains mixer, plus boiling water using the in-cupboard boiler. This makes cooking and cleaning far easier than before, saving you time waiting for water to boil on the stove or in a kettle.

Safety features

With taps becoming more and more sophisticated, safety is often a big concern for parents. Thankfully, the industry knows that safety isn’t up for negotiation. All three taps demonstrate this by having child-proof locks, preventing little hands from accessing hot water when parents aren’t around. The Grohe Red does this with a button and accompanying LED lighting system to show when the child-lock is on or off. The Fohen Fahrenheit and Athena taps, on the other hand, use a spring-loaded safety handle. 


Faulty appliances can prove to be a real headache, which is why looking at what warranties are offered can save costs and stress down the line. Let’s examine the warranty periods for our three boiling water taps:

Tap Warranty
Athena 5 years for tap, 2 years for boiler
Fohen Fahrenheit                           2 years (upgrade to 5 for £175)
Grohe Red 2 years (+1 year upon registration)

The Athena tap strides ahead when it comes to warranties, offering 5 years warranty for the tap and 2 years for the boiler. The Fohen Fahrenheit and Grohe Red taps come with 2 years as standard, which can be extended by 3 years or 1 year, respectively. The 3-year extension for the Fohen model comes at a price of £175, while the Grohe Red’s warranty extension is free after registering your product on the site.

There are lots of variables when it comes to boiling water taps, but hopefully, with today’s post, we’ve demonstrated that great features and designs don’t have to cost the earth.

There’s plenty to think about when designing a modern kitchen. From functionality to aesthetics, every aspect comes with a multitude of methods and looks. Your kitchen is the heart of your home and has a vital role to play in cooking and cleaning, which is why it pays to prioritise functionality when it comes to your taps. 

Taps are becoming increasingly sophisticated, offering more features than ever before - and today we’re cross-examining some of the top products on the market: our Quantum tap, Quooker’s Nordic Twin Taps and the Insinkerator 4N1 Touch.


When you’re renovating, upgrading or designing a kitchen, you’ve likely set a budget aside for each aspect. With that in mind, let’s see how the options weigh up:

Tap Price (as of July 2022)
Quantum From £469
Insinkerator 4N1 Touch From £1,149
Quooker Nordic Twin Taps                        From £1,200

There’s little question as to which tap comes out on top when it comes to affordability. At less than half the cost of the others, the Quantum model is as budget-friendly as you can get when it comes to boiling water taps. If you are looking to install multiple taps, the price of 4N1 and Nordic Twin Taps could quickly add up, so consider how much you’re willing to spend.


Aesthetics also matter in your kitchen, so here you can see what finishes and designs each model offers:

Tap Finishes
Quantum                               D-Shape: Matt Black | J-Shape: Matt Black, Brushed Nickel, Chrome or Copper
Quooker Nordic Twin Taps Square (D-Shape) or Round (J-Shape): Polished Chrome or Stainless Steel
Insinkerator 4N1 Touch     J-Shape, U-Shape or L-Shape: Chrome, Velvet Black or Stainless Steel

There are plenty of customisation options when it comes to shape and colour. Both the Quantum and 4N1 Touch offer the fashionable black boiling water taps that have become the darlings of interior design. All in all, the Insinkerator has the most options: 9, compared to Quantum’s 5 or the Nordic Twin Tap’s 4. 

But these choices come with an added cost. The Insinkerator’s most pricey finish - ‘Velvet Black’ - is £167 more than its standard ‘Chrome’ finish, while the Nordic Twin Tap’s ‘Stainless Steel’ finish adds an extra £240 to the final bill versus ‘Polished Chrome’. Quantum’s priciest finish - ‘Matt Black’ - is only £39 more than its least-expensive ‘Chrome’ finish.

Boiler size

Your boiler’s capacity will decide how much hot water you can access in one go. Usually fitted below your sink, it will maintain a constant reserve of hot water, ready for you to use instantly when required. Let’s take a look at the stats:

Tap Boiler size
Quantum 2.4L
Quooker Nordic Twin Taps                        3L, 7L (+£270), COMBI 7L (+£300)
Insinkerator 4N1 Touch 2.5L

In terms of the standard boiler, the Quooker Nordic Twin Taps take the edge with a 3L tank. You can upgrade to a 7L tank, though this will cost you an added £270. Following closely behind, the 4N1 and Quantum models are neck and neck with 2.5L and 2.4L tanks, respectively. 

A 2.4L tank will produce 5-6 cups of hot water at a time without the need to reheat, which only takes around 4 minutes. Unless you’re in a particularly large or busy household, this tank will have plenty of capacity for your cooking and cleaning needs.

Water types

All three taps in our comparison can dispense multiple types of water, but let’s compare what they can (and can’t) do:

Tap Can dispense
Quantum Cold, hot, boiling, filtered
Quooker Nordic Twin Taps                        Cold, hot, boiling + filtered & sparkling with CUBE (+£1,150)
Insinkerator 4N1 Touch Cold, hot, boiling, filtered

The Quantum and 4N1 Touch offer 4-in-1: cold, hot, boiling and filtered, straight out of the box. The Nordic Twin Taps offer three water types straight out of the box: cold, hot and boiling, with the option to add filtered and sparkling at an extra cost of £1,150. If budget isn’t an issue for you, the Nordic taps win here. However, cost-conscious homeowners will be pleased to see the other models offer four great functions at no extra cost.

Safety features

Boiling water is no doubt a danger if handled incorrectly, however, each model has its own child-safety mechanism to prevent little hands from turning on the tap, which is possibly why boiling water taps are shown to be safer than kettles. So whether you have 1 youngster or 10, you can rest assured that these taps are unlikely to cause accidents. Read more about boiling tap safety here.


Nobody wants the stress of a faulty tap, which is why warranties can be a crucial lifeline. They also demonstrate confidence in the manufacturer’s build quality. Let’s look at the warranties for our three models:

Tap Warranty
Quantum 5 years for tap, 2 years for boiler
Quooker Nordic Twin Taps                        2 years
Insinkerator 4N1 Touch 5 years for tap, 2 years for boiler

All three offer a warranty period, though the Quantum and 4N1 both come with a lengthy 5 years warranty for the tap and 2 years for the boiler. On the rare occasion that something goes wrong, that means you’re covered by the manufacturer for longer when it comes to sourcing spare parts.

The case has been made, but which hot water tap leads the pack? Offering state-of-the-art features at an unbeatable price, our Quantum tap can fit into the most modest of budgets. We firmly believe that having a modern kitchen shouldn’t cost an arm and a leg, so head over to our Quantum tap page and find out more. Alternatively, compare our full range of boiling water taps in our tap comparison guide.

In recent years, 4-in-1 taps have become a mainstay of the modern kitchen. Offering far more functionality than a basic mixer tap, they still deliver cold and hot water directly from the mains but with the addition of boiling water and/or filtered water. This means you can access pristine water straight from your countertop at a spectrum of temperatures perfect for a busy home.

There are lots of competing taps on the market, however, not all are created equal. We’re saving you the hassle of comparing each one by looking at three of the most popular: the Qettle Original, Minerva Helix and our very own Quantum model.


Cost is pivotal when comparing products - let’s see how the options weigh up:

Tap Price (as of July 2022)
Quantum                                 From £469
Qettle Original                          From £495
Minerva Helix                            From 1,747

It’s easy to see which of these models is the most budget-unfriendly. At over 3x the cost of the other two models, the Minerva Helix carries a far heavier price tag. If you have a fixed budget or your renovations are extensive, consider whether splashing out on this model is right for you.


Appearance is often second to price, so here we’ll compare what each model offers by way of finishes:




Matt Black (D-Shape), Matt Black, Brushed Nickel, Chrome & Copper

Qettle Original                  


Minerva Helix                  

Champagne Gold, Stainless Steel, Industrial Black, Copper & Anthracite

While the Quantum and Minerva Helix taps come in a plethora of different styles, the Quantum tap is the only one that offers a ‘D-Shape’ option. The Qettle Original, on the other hand, comes in just one, standard look. If appearances are paramount to your living spaces, consider whether a plain steel tap will tie into your unique style, or whether a different look would work better. In recent years, black boiling water taps, in particular, have sprung into fashion. Or perhaps a classic finish like copper could tie nicely into your cabinetry. Either way, the Helix and Quantum models offer plenty of looks to choose from.

Boiler size

The capacity of the boiler will decide how much boiling water you can access at a time. Sitting below your sink, it stores hot water ready for immediate use whenever it’s required. Here’s how the different models compare:

Tap Boiler size
Quantum                                    2.4L
Qettle Original                           2L, 4L (+£50), 7L (+£100)
Minerva Helix                             4.7L

Of the three, the Qettle Original has the smallest standard boiler tank, however, the option is there to increase this to a 4L or 7L tank, which would cost an added £50 or £100, respectively. The Quantum comes in next with a 2.4L tank, followed by the Minerva Helix with a 4.7L tank. A smaller tank will save you valuable cupboard space, however, if you’re in a particularly busy household or like to use a lot of boiling water to cook, you may be better off with a larger tank size. 

Safety features

Boiling water can be dangerous, however, all three of these taps offer a safety handle that prevents it from being turned on accidentally. In addition, the Minerva Helix has an insulated spout design which means the spout doesn’t get hot when you run boiling water through it. All in all, it’s easy to see that a lot of thought has gone into the safety of each model. Boiling water taps can be a safe alternative to kettles, and their safety handles offer a great line of defence against curious kids or pets.


The last thing anyone wants is their 4-in-1 tap to become faulty, which is why many manufacturers offer a warranty. Let’s check what the warranties are for our three models:

Tap Warranty
Quantum                                   5 years for tap, 2 years for boiler
Qettle Original                            2 years
Minerva Helix                          2 years on the tap, tank and filter housing

While they all come with a warranty period, we’re proud to say our Quantum model comes with 5 years warranty on the tap and 2 years for the boiler. That means our customers can depend on us for even longer to replace faulty parts, on the rare occasion something goes wrong.

Whether you’re a self-confessed tea addict or a pasta connoisseur, you can say goodbye to a slow-boiling kettle and access piping hot water straight from your worktop using a 4-in-1 tap. The options we looked at today are all state-of-the-art, however, our best-selling Quantum tap inches ahead with a better price, more customisation and an extended warranty.
