Are they Efficient?

The 4N1 Touch Tap dispenses instant filtered room temperature cold water, via unique touch button control, and instant filtered steaming hot water as well as regular hot and cold water, from the one combined fixture.
Which also means you only need to have one hole drilled into your countertop.

Can I Save money?

With a Boiling Water Tap you can do away with the need for multiple kitchen taps, a kettle and a water filter jug. So you're already saving part of the cost.
And you'll save even more by not having to keep boiling your kettle, and by using the filtered water in appliances like a coffee machine you save on limescale damage.

Is it Easy to install?

The InSinkErator 4N1 Touch Tap is easy to install, and has a temperature control so you can heat your water to the temperature that suits you - between 88° and 99°C.
You get a 2.5-litre water tank and filter included with your choice of tap.

What about Safety?

Protected by a locking safety lever, control the steaming hot water by pushing down and pulling towards you. In addition, there is a spring back feature that immediately shuts off the hot water when the lever is released, so there's no chance of steaming hot water running unattended.
Unlike many cheap boiling water tap alternatives, the 4N1 Touch Tap also has a fully insulated spout that is safe to touch even as steaming hot water is flowing through it. Safe for you, safe for your family.

How Fast will it be?

Dispenses filtered cold water for 30 seconds (1.2l), at the touch of a button. Automatically shuts off after 30 seconds.

Other benefits

Every InSinkErator steaming hot water tap comes equipped with an unobtrusive filter and tank system that fits snugly under your sink. The filter reduces chlorine, lead, turbidity and other unpleasant tastes and odours to ensure that you always have the purest filtered water possible.

The InSinkErator 4N1 Touch uses a fraction of the power of a normal kettle to heat up the water, by taking a little longer in the first instance when switched on - maybe up to 10 minutes. But when you get to your set temperature the InSinkErator 4N1 Touch maintains the temperature whereas a kettle loses heat quite fast. When you use the InSinkErator 4N1 Touch’s boiling tap, you only take out as much water as you need each time, so less energy is needed to top up the tank’s temperature.
