Installing a boiling water tap is a brilliant way to bring convenience and style to your kitchen—but like any appliance, it needs a bit of upkeep to keep it looking sharp and running smoothly. Whether you’ve chosen a 3-in-1 like or Revisita, Helena or Astrum models or 4-in-1 tap like our Quanta or Platina, a little maintenance goes a long way.

From tackling limescale to knowing what to do when you're away, here’s how to keep your tap in great shape.

Everyday Cleaning Tips

To keep your boiling tap gleaming, it’s best to give it a quick wipe after each use. A soft cloth, sponge, or kitchen roll will do the trick. Once a week, lather it gently with a drop of washing-up liquid and warm (not hot) water, then rinse and dry thoroughly with a clean cloth.

Avoid anything abrasive—scourers or harsh pads could damage the finish.

Tip: While cleaning, take care not to press the safety-lock mechanism on the boiling function.

Restore Shine with Natural Ingredients

Every few weeks, bring back the shine using a lemon solution. Just mix one part lemon juice with four parts water in a spray bottle. Spritz it over the tap, let it sit for a minute, then rinse and buff dry.

Stay away from bleach or strong chemical cleaners—they can tarnish both the tap and your sink.

What About the Boiling Water Tank?

The boiler tank itself doesn’t need much attention. Just check it monthly for signs of wear, like leaks or rust. If you notice your hot water tap leaking or the tank body looks damaged, switch the unit off at the wall and contact customer support. It’s important not to keep using it if you spot any issues.

Replacing the Filters

To ensure your system stays efficient and your water stays fresh, new filters should be changed every six months. 3-in-1 taps come with a carbon filter for boiling water, while 4-in-1 models include an extra one for cold filtered water. You can easily replace these yourself—no tools or technical knowledge needed.

Regular replacements also help prevent limescale buildup and keep the warranty valid.

Do Boiling Water Taps Need Servicing?

For the most part, no. Routine cleaning and the occasional filter change are usually enough to keep things ticking over.

However, if you notice:

• Your tap won’t turn on or feels stiff
• The boiler isn’t heating as expected
• There’s water leaking from the tank

…it’s best to have a technician take a look. These could be early signs of a bigger issue.

Limescale: What to Know

The in-built filter helps reduce limescale, but if you’re in a hard water area, some buildup can still occur over time. To remove it:

1. Mix lemon juice with water (1:4) and spray it directly on the limescale.
2. Let it sit for a few minutes.
3. Wipe away with a soft cloth—avoid scrubbing.
4. If it’s stubborn, try a 1:1 white vinegar and water mix.

An old toothbrush can help with tight spots—just use a light touch.

Does boiling water remove limescale?

Not quite. While boiling might kill bacteria, it actually encourages minerals to separate and form scale. That’s why filters are essential!

Should You Turn Off Your Tap at Night?

Wondering, "Should I turn off my boiling water tap at night?" No need! The boiler is designed to maintain a steady temperature using very little energy. Turning it off every night could actually use more power when reheating the tank from cold the next day.

Going Away?

If you're away for a short time—up to two weeks—just leave the tap running as normal. For longer periods, you can turn it off to save energy. And if the weather’s looking frosty, it’s worth draining the system to avoid pipe damage.
