How to Install a Boiling Water Tap

Boiling water taps have revolutionised the modern kitchen, drastically cutting down on the time it takes to complete everyday tasks and chores. Whether you're an avid coffee drinker or you're more than happy with a hot green tea, with the help of a boiling water tap you can have instant boiling water at your fingertips. That means less time waiting for the old-school kettle to boil and more time sipping on your favourite hot drinks.

But that's not the only use of a boiling water tap. With a 3-in-1 or 4-in-1 tap, you can:

  • Sanitise baby bottles, cutting boards and knives
  • Kill weeds and clear gutters
  • Clean your floors fast and effectively
  • Remove stubborn stains
  • Cook your favourite dishes at lightning speed - from steamed vegetables to pasta, noodles and potatoes

If you’re ready to upgrade your kitchen with a boiling water tap, the process to install one is actually much simpler than you might think. Here’s our handy guide on boiling water tap installation, step-by-step:

1) Switch off your water supply

Before you start the installation process, make sure to switch off your water mains supply. This will help prevent any accidents from occurring during the installation; I'm sure we'd all prefer your kitchen floor remains dry and undamaged!

2) Measure out the best space for your boiler

Each boiling water tap comes supplied with a 2.4l boiler, which is perfect for under-sink cabinets where space is already limited. The exact dimensions of our boilers are:

  • height: 295mm
  • width: 184mm
  • depth: 184mm

You should consider how the boiler tank will fit into your cupboard by measuring its interior and creating a dedicated space. It's also a good time to check the plug socket you'll use is undamaged and safe. The boiler's electrical cable we supply is 1.5m.

Each boiling tap also comes with a filter, which will need to be installed beside the water tank. The dimensions for this are:

  • height: 295mm
  • width: 84mm
  • depth: 84mm

3) Clear out your cupboard

Once you've figured out where you'll fix your boiler, completely clear the cupboard and give it a clean down to ensure it's free of debris and dry. Next, remove your old tap and use a bucket or container to catch water which may be left in the hot and cold feeds. Then, place the boiler so it's in

reach of the feeds and plug socket but don't plug it in yet.

4) Fit your boiling water tap

Feed the tap's hot and cold feeds through the tap hole at the back of your sink and follow the instruction manual provided to secure the tap to your sink. If you're unsure about this stage, it may be best to seek the help of a professional plumber who can handle this part (or all) of the installation for you.

5) Connect your boiler

Once your tap is secured to your sink, connect your boiler to the filter and then the tap, following the instructions provided. Ensure screws and bolts are screwed on tightly to prevent leakages and check for any defects or damage.

6) Plug in your boiler

Next, you can plug your boiler into the safe plug socket and turn your water supply back on. Once you've turned on your water supply, you should check your water pressure. The operating pressure of our taps is between 0.5 to 5.0 bar. If your pressure is below or exceeds this, you should turn off your supply and consult a plumber who can advise on ways to increase or decrease your water pressure. Continuing to operate your hot water tap if the pressure is not in this range may void your warranty.

7) Wait until the boiler fills and heats up

Before you can access instant boiling water, you will need to wait until the boiler fills and heats to 98°C - this may take up to 15 minutes. If you would like your water to heat to a lower temperature, you can use the touch-screen control on the boiler to set a temperature between 75°C and 98°C.

8) Enjoy instant hot water

Now you can enjoy boiling water at the turn of a handle. Our boilers can deliver 6 or 7 cups of piping-hot water at a time, with only 3-4 minutes' wait time to reboil, so you can supercharge your everyday cooking and cleaning jobs and do more of the things you love.

Stay safe

We believe our boiling water taps are infinitely safer than spluttering kettles, but we understand that parents may be worried about their little ones. Our safety features include a child-safe mechanism that does not allow boiling water to flow unless the spring lock is disabled. This means your child can still access hot and cold water in the same way as before but not boiling water.

Hire a professional if needed

Our boiling taps are easy to install for those with a tool box and a basic knowledge of DIY, however, for those who are unsure or lack experience, we advise seeking the help of a plumbing or electrical professional. They can make the process straightforward and drastically reduce the chances of a faulty installation.
