Why this model

A 1 kg unit for basins and kitchens

The lightest body in the range — 150 mm wide, 24 to a 24 kg carton.

White or black in stock

White or black in stock

Both colours are held as stock. The logo is laser-etched from 100 pieces, with custom packaging from 1,000.

3.5 kW on a 2 mm² cable

3.5 kW on a 2 mm² cable

Rated for 2 mm² copper core. In older buildings that is usually what is already behind the wall, so the heater goes in without re-running the circuit.

Basin, sink and washroom

Basin, sink and washroom

A body small enough to sit under a basin or beside a sink, and light enough to mount on a partition wall without a support frame.

Fast heating, low-pressure start

Fast heating, low-pressure start

Hot water in about three seconds, and it starts on low water pressure — so it still works on upper floors and gravity-fed lines.
