Owning Your Boiling Water Tap: How They Work, Maintenance Tips & More

A boiling water tap is one of the most convenient additions to a modern kitchen, delivering instant boiling water alongside your everyday hot and cold supply. Whether you are making tea, speeding up meal preparation or enjoying filtered drinking water, understanding how your boiling water tap works helps you get the very best from it.

In this LUSSO buying guide, we’ll explain how boiling water taps operate, how to use them safely, average running costs, and simple maintenance steps that will keep your Filtrata boiling water tap performing beautifully for years to come.

What Is A Boiling Water Tap?

A boiling water tap delivers near-instant boiling water directly from your kitchen tap, eliminating the need to wait for a kettle to boil. By combining multiple water functions in a single fixture, it helps to reduce worktop clutter and make everyday kitchen tasks quicker and more efficient.

Whether you are preparing hot drinks, cooking meals or filling pans, boiling water taps provide a practical, space-saving solution without compromising on style.

How Does A Boiling Water Tap Work?

A boiling water tap is installed by fitting a compact insulated tank beneath your sink, connecting it to both your mains water supply and an electrical power source. The tank heats and stores water so it is always ready whenever you need it.

When the boiling water function is activated, hot water is drawn directly from the tank and delivered through the tap almost instantly. An integrated filtration system helps improve water quality and taste while reducing impurities and minimising limescale build-up inside the system.

The Filtrata collection offers 4-in-1 functionality, combining boiling water, filtered cold water, standard hot and cold water from a single beautifully designed tap.

How to Use a Boiling Water Tap

Learning how to use a boiling water tap is simple. Once installed, boiling water is available within seconds, making everyday kitchen tasks faster and more convenient.

Common uses include:

  • Making tea, coffee and other hot drinks.
  • Filling saucepans for cooking.
  • Speeding up food preparation.
  • Sterilising utensils when required.
  • Removing the need for a separate kettle and creating a less cluttered worktop.

The combination of instant boiling water with filtered cold and standard hot and cold water makes a 4-in-1 boiling tap a practical solution for busy households.

How Much Does a Boiling Water Tap Cost to Run?

One of the most common questions homeowners ask is ‘how much does a boiling water tap cost to run?’.

Running costs vary depending on your household's water usage, energy tariff and how frequently boiling water is used throughout the day. However, because the insulated tank stores heated water efficiently rather than repeatedly boiling fresh water like a kettle, boiling water taps are generally very economical to operate.

The Filtrata boiling water tap is designed to be highly energy efficient, with running costs from as little as 3p per day under typical usage. Alongside the convenience of instant boiling water, this can help reduce both energy consumption and unnecessary water waste.

Is A Boiling Water Tap Safe?

Although boiling water taps dispense extremely hot water, they are specifically designed with safety in mind and are perfectly suited to everyday family kitchens.

Filtrata models include a fully insulated 360° spout that remains cool to the touch during normal use, helping reduce the risk of accidental burns. They also feature a child-safe locking lever, preventing boiling water from being dispensed unintentionally.

As with any appliance that produces boiling water, care should always be taken during use, particularly around young children. By following the product instructions and using the safety controls correctly, you can enjoy the convenience of instant boiling water with complete confidence.

Should I Turn Off a Boiling Water Tap at Night?

A common question is ‘should I turn off a boiling water tap at night?’. In most cases, the answer is no. Boiling water taps are designed to remain switched on so boiling water is always available when needed, while using minimal energy to maintain temperature.

You may wish to turn the system off if you're going away for an extended period or carrying out maintenance. If you're unsure, the LUSSO team will be happy to advise on the best approach for your specific model.

Boiling Water Tap Maintenance

Keeping your Filtrata boiling water tap clean and well maintained will help preserve both its appearance and performance for years to come. Regular cleaning and timely filter changes ensure consistently great-tasting water while protecting the internal components from unnecessary wear.

How to Clean a Boiling Water Tap

Understanding how to clean a boiling water tap properly helps maintain its premium finish and prevents accidental damage.

Clean the tap regularly using a soft microfibre cloth, warm water and a small amount of mild washing-up liquid. After cleaning, rinse thoroughly and dry with a clean, soft cloth to maintain its shine.

Avoid using:

  • Abrasive cleaners.
  • Scouring pads or steel wool.
  • Harsh chemical kitchen cleaners.
  • Cream cleaners containing abrasive particles.

Products designed to remove stubborn stains can scratch or dull the surface over time, reducing the appearance of your brassware. Gentle, regular cleaning is all that's needed to keep your Filtrata looking immaculate.

Why Should I Change the Filter on a Boiling Water Tap?

Regular filter replacement is one of the most important aspects of boiling water tap maintenance.

The filter continuously removes impurities from your drinking water while helping reduce limescale inside the system. Over time, it becomes saturated with trapped particles, reducing its effectiveness.

Replacing the filter helps:

  • Remove limescale, magnesium and sediment.
  • Reduce chlorine taste and odour.
  • Remove lead, organic compounds and protozoan cysts.
  • Filter particles down to one micron.
  • Maintain optimal water flow and system performance.

If the filter isn't changed regularly, particles and limescale can build up, affecting water taste, reducing flow and placing unnecessary strain on the system. This is particularly important in hard water areas, where limescale accumulates much more quickly.

When it's time for a replacement, simply install a new Filtrata 4-in-1 Cartridge Refill to keep your tap performing at its best.

How Often Should I Change the Filter on a Boiling Water Tap?

How often you replace your filter depends largely on the hardness of the water where you live.

We recommend changing your filter:

  • Hard water areas: Every 3 months
  • Medium water areas: Every 4 months
  • Soft water areas: Every 6 months

Changing the filter at the recommended intervals helps maintain excellent water quality while protecting your boiling water tap from excessive limescale build-up.

How to Change the Filter on a Filtrata Boiling Water Tap

Replacing the filter is a straightforward process.

  1. Isolate the mains water supply.
  2. Switch off the power to the boiler unit.
  3. Position a bowl beneath the filter to catch any remaining water.
  4. Turn the existing filter clockwise to remove it.
  5. Dispose of the old filter responsibly.
  6. Install the new filter by tightening it securely into position.
  7. Restore the water supply.
  8. Turn the power back on and allow the system to refill before use.
