Boiling Water Taps

Boiling Water Taps Ireland – Instant Filtered Boiling Water at the Sink

Boiling water taps replace three things at once: the kettle, the filter jug and the kitchen mixer. A dedicated lever draws filtered water at up to 98°C in about two seconds; the other side is an ordinary hot-and-cold mixer. The working parts — an insulated tank and a carbon filter — live in the cupboard below, so the worktop gets an appliance back.

Each system is supplied complete with the tap, the tank, the filter and the fittings to connect them, and the finish is what changes between them. Polished chrome blends with a stainless sink and most existing kitchens. Matt black hides water spotting, and its tap matches the black cupboard tank rather than contrasting with it. Brushed brass is the statement, and wants brass or gold tones elsewhere in the room to answer it.

Temperature is adjustable on a touch screen from 75°C up to 98°C, so the same tap suits green tea, baby bottles, French press coffee and blanching. The boiling side is a separate lever from the everyday mixer, deliberately distinct so it cannot be turned on by reaching across.

What to Check Before You Order

Three things decide whether a boiling water tap will work in your kitchen, and all three are worth checking with a tape measure rather than assumed.

  • Cupboard space. The tank stands on the base of the sink cupboard and needs clear room around it — the systems here are around 330 mm tall, 210 mm wide and 224 mm deep, with the exact figures on each product page. The filter needs a little over 300 mm of wall beside it.
  • A 13A socket. The tank plugs into a standard fused 3-pin socket on a short cord. If there is no socket in the sink cupboard, fitting one is an electrician's job and often costs more than people expect.
  • Water pressure. These run from 1 bar to 3 bar. A combi boiler or pressurised mains is what they want; a gravity-fed cylinder in the hot press will not drive them properly.

Get those three right and the rest is a straightforward single tap hole installation.

Running Costs and Upkeep

A boiling tap holds water at temperature continuously, drawing a couple of watts on standby — small, but not nothing. Against that, you stop boiling a full kettle to make one cup, which is where most domestic waste actually sits. Households making tea and coffee through the day tend to come out ahead; a house that boils water twice a week will not.

The only routine maintenance is the carbon cartridge, changed every three to six months depending on how hard your water is. It keeps the water tasting clean and, more importantly, stops calcium bonding to the heating element inside the tank. Replacements are stocked here as the inline water filter kit, which fits every tap on this page.

Frequently Asked Questions

How does a boiling water tap work?
A small insulated tank in the sink cupboard holds water at temperature all the time, so there is no waiting when you draw it. Cold mains water passes through a carbon filter on its way in, the tank keeps it between 75°C and 98°C at whatever you set on the touch screen, and pressing the dedicated lever delivers it through the same spout as your normal hot and cold. The systems here use tanks of around 2.4 litres heated by a 1.5 kW element from an ordinary 13A socket, with the exact figures listed on each product page. Because the water is already hot, delivery takes about two seconds rather than the two to three minutes a kettle needs.
What does a boiling water tap cost to run?
Two figures matter. The element draws its full wattage only while actively reheating, which is brief, and the tank sits at a couple of watts on standby the rest of the time - roughly comparable to leaving a phone charger plugged in. The saving comes from the other direction: most people boil a full kettle to make one cup, and a tank draws only what you actually take. Whether you come out ahead depends entirely on how often the kettle currently goes on. A household making tea and coffee through the day usually does; one that boils water a couple of times a week will not, and a kettle remains the sensible answer.
What is the difference between a 3 in 1 and a 4 in 1 tap?
A 3 in 1 gives you filtered near-boiling water plus ordinary hot and cold from one spout. A 4 in 1 adds chilled filtered water, which means a second unit in the cupboard, a second thing to maintain and noticeably more space taken up. Check the product page for which arrangement a particular tap uses - it is stated in the title and the specification table. If chilled water is the reason you are looking and you cannot see what you need, ask us: our suppliers carry more than we list online.
Can I install one myself, or do I need a plumber?
The tap itself is a single tap hole fit, no harder than swapping a mixer. The parts that catch people out are the tank and the electrics. The tank needs to be secured in the cupboard, plumbed into the cold feed through the filter, and plugged into a 13A socket within reach of its cord. If that socket already exists and you are comfortable with compression and push-fit connections, it is a competent DIY job. If the socket does not exist, you need an electrician for that part regardless of who does the plumbing - so find out before you order rather than after the box arrives.
How do I choose between the finishes?
Start with what is already in the room rather than with the tap. Polished chrome sits comfortably with a stainless sink and almost any existing kitchen, and is the safe choice if the tap is not meant to draw the eye. Matt black hides the water spotting a polished finish shows at a busy sink, and its tap matches the black cupboard tank. Brushed brass needs something else warm in the room to answer it - a brass sink, gold handles, a pendant light - or it reads as the one thing that does not match. Note that coated finishes dislike descaler, so keeping the filter fresh matters more on those than on chrome.
What should I compare when choosing a boiling water tap?
Four things, and model names are the least useful of them. Tank capacity decides how many cups you get before it needs to recover. Temperature range decides whether it suits green tea as well as pasta. Minimum pressure decides whether it will work on your plumbing at all - anything rated from 1 bar rules out a gravity-fed cylinder. And the filter replacement interval and part cost decide what it asks of you every few months. Compare those four across any shortlist and the decision usually makes itself, whatever badge is on the spout.
Is 98°C hot enough, and is it safe?
98°C brews tea and blanches vegetables perfectly well and sits just below a rolling boil, which is normal for tank-based taps - it stops steam and spitting at the spout. You can dial it down to 75°C for green tea or bottles. On safety, the boiling side is a separate lever from the everyday mixer, so it is not something you turn on absent-mindedly. Treat it as you would a kettle: it delivers water that will scald, and small children should not be able to reach the lever unsupervised.
