Boiler Tanks for Boiling Taps: Everything You Need to Know

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 standard 2.4-litre tanks are the perfect fit for the modern kitchen.

How big is your boiler tank?

Our tanks are designed to be compact and able to fit in the vast majority of under-sink cupboards.

The exact dimensions of our 2.4-litre boiler unit are:

Height - 295mm

Width - 184mm

Depth - 184mm

We have also launched our new, upgraded-capacity 4-litre tanks - these cost an extra £99.

The exact dimensions of our 4-litre boiler unit are:

Height: 272.5 mm

Width: 197 mm

Depth: 299.5 mm

How much water can your tanks dispense?

Our standard 2.4-litre 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 when it's needed.

If you want to upgrade the tank to a 4-litre version, you can for just £99. These tanks can dispense up to 10 cups of boiling water at a time, making them perfect for busy family homes or extensive tea rounds!

What temperature does the tank reach?

All of our boiler tanks (except for Avista) 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. It's true: the perfect cup of tea is brewed at 98°C, not 100°C!

Avista will heat the water to 98°C as standard.

What about the filter?

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. Learn more about filters here.

Will I need a plumber to install my tap and tank?

Our taps are designed to be simple to install. With basic plumbing knowledge and our instructions, you should be able to fit your boiling water tap yourself. However, if you have any doubts, we recommend seeking professional help to prevent any issues that could crop up from a faulty installation. You can watch videos on how to install our taps on our YouTube channel.

Each and every one of our products is designed to be both safe and reliable, making them the ideal addition to the contemporary family kitchen.
