What is a Boiling Water Tap?

Boiling water tap

A boiling water tap delivers instant hot water whenever you need it – perfect for hot drinks, with no more need for a kettle in your life.

While some instant hot water taps take the water temperature right up to 100C, most are delivered at a 98º-99ºC. Others also offer a filtered cold water function. So it is important to understand the variations available and specify which combination you require before ordering.

Types of boiling water tap

However, adding a hot water tap doesn’t mean having to add a second tap to your kitchen sink. Here are the types of boiling water tap you could consider replacing your regular kitchen tap with:

  • Two-in-one tap: Dispenses both boiling and mains cold water
  • Three-in-one tap: Dispenses boiling, as well as your mains hot and cold water
  • Four-in-one tap: Dispenses, boiling, hot & cold water from mains, plus cold filtered water.
     

How does the hot water tap work?

Boiling water taps have a small thermal-insulted tank which needs to be stored nearby, as it keeps the water it uses in its own hot tank. By pressing the handle, near boiling hot water is released through the tap and cool tap water flows into the tank to replace what is used.

Benefit of an instant boiling tap:

  • Quick Access: Installing a boiling water tap will revolutionise the way your kitchen works at home. It will make your quick fresh hot cuppa a breeze, help with faster food preparation, as well as tackle tough stains and general cleaning.
  • Efficiency: Having instant access to boiling hot water, will mean little to no use for a traditional kettle in your home. You will however save on water, time and energy waste by using a boiling water tap compared to when filling a kettle for your next cup of tea! However, the higher initial installation, investment and ongoing maintenance costs make it is difficult to argue that it is a cheaper option in the long run.
  • Safety Covered: Despite the name, a boiling water tap has various safety features to avoid scolding, particularly in a family kitchen. Childproof handles and double-click functions help avoid scolded fingers. Plus, it is much easier to use for people who have trouble lifting and filling heavy kettles.
  • Filtered Water: If you would also like a cold filtered water option, most models can cater for this too. So if you want to avoid chemicals and the taste of the mains water in your area, this tap could also solve that problem.
     

How to install

Boiling water taps will need to be permanently plumbed in alongside your usual kitchen sink taps.

Boiling water taps require space for an additional water tank, which is often stored underneath the worktop nearest your tap, as well needing a water supply and three-pin plug in close proximity.

There are a variety of tank capacities, from 2 litres to 11 litres. The required capacity will be dependent on the amount of boiling water that is typically needed at once by the user – but smaller capacity tanks are usually adequate for in the home and take up less room beneath the sink.

Hot water tap maintenance

A filter will also need to be included in a hot water tap, which will need replacing every 6 months to 5 years, dependant on the brand and tank capacity, in order to help prevent limescale.

Manufacturers recommend you change the filter every six to 12 months and in some cases can invalidate the warranty if you do not. A descaling solution, to clean the inside of the tank, is also recommended by some manufacturers.

The boiling water tap however, can be cleaned like any other kitchen tap.
