The energy-efficient choice

These units are permanently plumbed in and as water is dispensed the unit refills, allowing you to draw off multiple cups of boiling water at any one time, making them ideal for busy workplaces.

Robust and reliable boiler

The stylish and compact unit features a stainless steel casing which is easy to clean and maintain in professional catering environments. the sleek, mirrored design also makes it an ideal solution for front-of-house catering services.

The robust non-drip taps allow for speed and convenience during periods of high usage, as well as ensuring the safety of users.

Installation requirements

To ensure that the unit can be installed quickly and smoothly in your proposed location, each unit will require a 13A (240V AC) fused spur which should not be more than one meter from the machine.

Each plumbed water machine needs to be supplied with water from a rising main. The pipework should ideally be no more than one meter from the machine, although our in-house service team can install machines in the majority of locations.
