Boiling Water Tap FAQs

Are you thinking of buying a boiling water tap? Here are the most commonly asked questions from new customers:


How do boiling water taps work?

Our taps come with a boiler tank that holds up to 2.4 litres of near-boiling water, which can be drawn through the tap with the turn of a handle. The boiler tank (and accompanying filter) is installed below your kitchen sink and is designed to be as compact as possible. Find out more about how our taps work here.

What is a 3-in-1 tap?

A 3-in-1 tap has three functions:

  1. Filtered boiling water
  2. Cold water
  3. Hot water

The regular hot and cold water is drawn from your mains water supply like a standard kitchen mixer tap. The boiling water is stored in a boiler tank after being filtered and can be drawn by using a separate handle. Shop our 3-in-1 taps here.

What is a 4-in-1 tap?

A 4-in-1 tap has four functions:

  1. Filtered boiling water
  2. Filtered chilled water
  3. Cold water
  4. Hot water

The upgraded system of a 4-in-1 tap allows you to access filtered water (along with filtered boiling water and standard hot and cold water) perfect for drinking or using in your recipes. Shop our 4-in-1 taps here.

What is a flex boiling water tap?

A 'flex' boiling water tap has a pull-out spout, which you can use to move the flow of water around your kitchen sink. This can be a 3-in-1 or a 4-in-1 tap. For safety reasons, many 'flex' taps won't allow you to use the boiling water function when the spout is pulled out. Shop our flex taps here.

What temperature does a boiling water tap run at?

Our boiling water taps deliver up to 98°C water, which makes for a more efficient system as less water is lost as steam. Our touch-screen tanks come with 5 temperature presets: 75°C, 85°C, 90°C, 95°C and 98°C. This means you can customise your tap to your desired setting.

Should I turn off my boiling tap at night?

No, it is unnecessary to turn off your boiling water tap at night. The tank is designed to be ultra-efficient and can maintain its temperature at the expense of very little energy. In fact, turning the tank off and allowing it to cool will only cost more as the tank will need to reheat in the morning.

I'm going on holiday - should I turn my tap off?

For holidays of 7 days or less, we would recommend leaving it on. If you are going away for longer, you may wish to switch your tap off to save energy. To do this, you can simply switch the tank off using the touch-screen and then turn it off on the wall. When you return, we recommend draining the tank completely and allowing it to refill.


Are boiling water taps expensive to run?

We have designed our boiling water taps to be extremely energy-efficient, costing less than 10p a day to run. The greatest saving, however, is time. With a boiling water tap, you'll no longer have to wait for the kettle to boil or juggle multiple kettles of water.

Does a kettle or a boiling water tap cost more to run?

Kettles cost a few pence per boil, which means they may cost more to run if they're used multiple times a day.


Are boiling taps environmentally friendly?

Built using advanced hardware, our boiling water taps use very little energy to heat the water within the tank. A heavily insulated tank also ensures little energy is required to keep the water at high temperatures. What's more, our 4-in-1 taps remove the need for expensive and environmentally damaging bottled water, offering pure chilled water on tap, whenever you need it.

How long does a boiling water tap last?

Our taps are designed to last for years, even in areas with hard water. A boiling water tap that has been properly maintained may last up to a decade or longer. What's more, our 2-year warranty on the tap and one year on the tank ensures you are covered in the rare event that your tap malfunctions.


How do you install a boiling tap?

It's a relatively simple process to install a boiling water tap, requiring just a few tools and basic DIY/plumbing skills. The job becomes more complex if you need to fit a new plug socket - we recommend you hire an electrician in this instance.

Your tap will come with a detailed installation guide for you or somebody else to follow. In basic terms, you will need to:

  1. Fit your tap to the kitchen sink
  2. Fit the boiler tank in the cupboard below your sink
  3. Connect the tank to the provided filter and then your mains water supply
  4. Connect the tap to the tank
  5. Plug the tank in on the wall and turn it on
  6. Allow the tank to fill with water and heat up (this may take up to 10 minutes the first time)
  7. Test each water function by turning the handles
  8. Enjoy!

Do you need a plumber to install a boiling water tap?

It's not necessary to hire a plumber to install a boiling water tap, however, if you have little DIY or plumbing knowledge we do recommend seeking professional help. Equally, if your installation requires a new plug to be fitted, we also suggest seeking a tradesman.

Can a boiling water tap be installed in a hard water area?

Our filters are designed to remove unwanted minerals and chemicals from the system, reducing the build-up of limescale and prolonging the life of your boiler tank and tap. To ensure your filter works at maximum efficiency, we recommend changing your filter every 6 months. You can purchase replacement filters here.


Are boiling water taps easy to maintain?

Yes, a boiling water tap is simple to maintain. Besides changing the filter every 6 months, you will need to do little to keep it running smoothly. We do recommend checking the fittings every few weeks just to make sure everything is secure and is working as it should. If you do experience any problems, we suggest you get in touch as soon as possible. Learn more about maintaining your boiling water tap.

How do I clean my tap?

Your tap can be cleaned with a non-abrasive sponge and a drop of washing-up liquid. Simply lather the tap with the washing-up liquid, rinse it off with lukewarm water and then buff it dry with a microfibre cloth. We recommend you do not use abrasive chemicals (including bleach) or scrubbers as this can damage the finish on your tap. This is particularly important for our black boiling water taps.


Are instant boiling water taps safe?

Yes, our taps are designed with safety in mind. The spring-loaded mechanism prevents little ones from accessing boiling water, while also switching the boiling water function off when you move away from the sink. What's more, at 98°C, the near-boiling water is dispensed in a steady stream without spluttering.

Are boiling taps safer than kettles?

Our taps are safer than kettles for a few reasons:

  1. They can't be moved around the room, unlike a kettle
  2. They don't become hot to the touch, unlike a kettle
  3. They have a spring-loaded mechanism to prevent children from accessing boiling water

What is your warranty?

We offer a 1 year warranty on our taps, and 1 year warranty on our boliers and parts, depending on the model of tap you buy.

Do we need to do anything to keep the warranty valid?

For your warranty to be valid, you must replace the filter regularly - at least once every six months. The tap should also be installed in accordance with the installation manual - alterations may void the warranty.
