7 kW cast aluminium element
Die-cast aluminium heating body — hot water in about two seconds, with no storage tank and no standby heat loss.
A 7 kW heater in a 190 × 55 × 260 mm body weighing 2.4 kg — small enough for a kitchen cabinet, a washbasin or a holiday flat, and it can be mounted in any orientation. Cast aluminium element, hot water in about 2 seconds, stepless 30–55 °C and water–electricity separation.
MOQ 100 pcs for custom panel colour, pattern and logo · 1,000 pcs for custom packaging. Samples from 1 pc — the sample price is higher than the bulk price, and we refund the difference once you place a bulk order within 30 days of receiving the sample. Prices are quoted per order, EXW Shanghai — tell us your quantity and destination port and we will reply within one working day.
Why this model
The lightest unit in the range, with the same control and safety package as the 8.5 kW models.
Die-cast aluminium heating body — hot water in about two seconds, with no storage tank and no standby heat loss.
Heating element and water channel are physically separated: safer operation, higher thermal efficiency and no scale build-up.
LED temperature display with touch controls on a tempered glass panel, adjustable step by step from 30 to 55 °C.
Over-temperature, dry-heat, leakage and ground-fault protection — a 40 A leakage protector ships with every unit.
A clear digital read-out you can read from across the room, with fault codes instead of guesswork when something needs attention.
Mount it vertically or horizontally — the body can be installed in any orientation, inside a cabinet or on an open wall.
