2 mm² cable, no upgrade
Rated for 2 mm² copper core. In older kitchens and utility rooms that is what is already behind the wall, so the heater goes in without an electrician re-running the circuit.
A flat-panel under-sink heater. Same 180 × 70 × 150 mm footprint and 1 kg body as the GB-10, but specified for 2 mm² copper cable so it fits buildings where the supply cannot be upgraded. 3,500–5,500 W element, water in about three seconds, outlet held between 30–55 °C.
MOQ 100 pcs for custom panel colour, pattern and logo · 1,000 pcs for custom packaging.

Why this model
Where the wiring is already in place and an upgrade is not on the table.
Rated for 2 mm² copper core. In older kitchens and utility rooms that is what is already behind the wall, so the heater goes in without an electrician re-running the circuit.
A stainless steel tube element heats only while water flows, reaching temperature in about three seconds with no storage loss.
The flat body sits tight to the cabinet wall, leaving room for the waste trap and the pipework already under the sink.
White as standard, black on request. Logo from 100 pieces, custom packaging from 1,000.
