The InSinkErator 3-in-1 handles the jobs you’d expect from an ordinary kitchen tap, then adds filtered near-boiling water from the same fitting. Use the standard hot and cold supply for washing up, and turn to the heated supply when you’re making tea, coffee, or preparing a pan for cooking.
Its angular chrome design gives it a modern look without requiring a second tap beside the sink. For anyone comparing boiling water taps with tanks, it’s a way to bring all three water options together while keeping the heating tank beneath the worktop.
Hot Water Without the Kettle Wait
The compact tank holds 2.5 litres and can heat water to a maximum of 98°C. Its controls let you select the temperature you want, so hot water is ready to dispense when you need it. You can take just the amount required for a cup or pan, although running costs will depend on how often you use the tap and the temperature selected.
The tank fits inside the cupboard beneath your sink. Ask your installer to check the available space, plumbing, and power supply before ordering.
Two-Stage Filtration
Water passes through two stages of filtration before reaching the heated supply. These are designed to reduce calcium and limescale and improve the taste of water used for hot drinks. InSinkErator recommends replacing the filter every six months to maintain performance.
Separate Levers for Everyday Use
The tap has one lever for standard hot and cold water and another for the near-boiling supply. Keeping the controls separate helps reduce the chance of selecting near-boiling water when you intended to use the ordinary tap. As the water can reach 98°C, it should still be used with care.
Flexible tails are included to help connect the tap to suitable pipework.
Flow Rates
The following flow rates are supplied in litres per minute, with figures shown for the mixed and near-boiling water supplies:
0.5 bar: 5.1 mixed; 1 near-boiling
1 bar: 7.3 mixed; 1.5 near-boiling
2 bar: 10.4 mixed; 2.2 near-boiling
3 bar: 12.9 mixed; 2.6 near-boiling
4 bar: 14.9 mixed; 3 near-boiling
5 bar: 16.7 mixed; 3.3 near-boiling
The tap has a two-year warranty, and the tank has a one-year warranty.

We purchased this item just before Christmas as our previous one started leaking . Unfortunately we had to wait until 15012026 for the plumber to install it. So far it is working excellently

We had the 4in1 at our old house, but the filter water never got cold enough, so we bought the 3in1 this time. It makes drinks and cooking so much faster! Couldn’t live without one.

Excellent product and easy to install although ugh the instructions didn't mention what to do with a small plastic bit which caused a small flood but eventually figured it out.
Plumbworld have been excellent with keeping me informed on dispatch and delivery dates, especially as part of the order wasn't in stock.

Several years ago with my new kitchen I was sold a InSinkErator boiling Tap Combined with cold water. Although I love the instant boiling water I miss having hot water straight from my boiler for washing-up and hand washing.
I am now replacing it with
InSinkErator 3 in 1 Kitchen Tap as we have been more than happy with our InSinkErator. Now waiting for the plumber to install
Efficient and quick service so well pleased
