4-in-1 Boiling Water Taps

Boiling, filtered chilled, hot and cold from a single tap. The 4-in-1 adds a chiller tank to the boiling tank, so you get cold filtered drinking water without a jug in the fridge. Square, swan neck and pull-down spray styles, in chrome, matt black, gunmetal grey, brushed nickel, brushed copper and brushed gold.

This is the widest choice of finishes in the range, which makes it the one to pick if the tap has to sit alongside a particular set of handles or a coloured sink. Bear in mind it needs space for two tanks under the sink, not one.

What the fourth function adds

• Filtered chilled water on tap, so no jug taking up fridge space.
• The same filter serves the drinking water, so it is doing two jobs.
• Needs a chiller tank as well as the boiling tank — check your cupboard depth.
• The pull-down swan neck version adds a spray head for rinsing as well.

Also in this range: all boiling water taps, 3-in-1 taps and tanks and filters.

Frequently asked questions

How cold is the chilled water?

The chiller tank holds filtered water at fridge temperature, so it pours cold rather than merely mains-cool. It recovers between draws, so very heavy use will see it warm up before catching back up.

Do I need two sockets under the sink?

Both tanks need power. Some installations run them from one fused switched socket with a double outlet; check the requirements on the product page and have an electrician confirm the circuit is up to it.
