3-in-1 Boiling Water Taps

One spout, three temperatures: near-boiling, hot and cold. A 3-in-1 tap replaces your existing kitchen mixer and needs a single insulated tank in the cupboard below, which makes it the simpler and more compact of the two boiling tap formats.

If you mainly want to stop using the kettle, this is the version to buy. Step up to a 4-in-1 only if filtered chilled drinking water matters to you, because that needs a second tank and more cupboard space.

3-in-1 or 4-in-1?

• A 3-in-1 needs one tank, so it leaves more usable space in the sink cupboard.
• Hot and cold run through the tap as normal, so you lose nothing by switching.
• Cold water is filtered on its way through, which helps protect the tank from scale.
• Fewer components means less to go wrong and a lower fitted cost.

Also in this range: all boiling water taps, 4-in-1 taps and tanks and filters.

Frequently asked questions

What are the three functions?

Near-boiling water on one control, plus your normal hot and cold on the other. The boiling side draws from the insulated tank; hot and cold come from your existing supplies.

Can I upgrade a 3-in-1 to a 4-in-1 later?

Not by adding a tank — the tap body itself has to be plumbed for the chilled circuit. If filtered chilled water is likely to matter to you, buy the 4-in-1 from the start.
