Why this model

You can see the temperature before you step in

A live LCD read-out plus flow-rate control, in a 105 mm body with the shower set in the box.

Shower set in the carton

Head, flexible hose and wall bracket ship inside the box. That removes a second purchase order and a second delivery for the installer.

LCD display, flow control

LCD display, flow control

The screen shows the live outlet temperature and the knob sets the flow — no guesswork, no hot-and-cold swings between 25–55 °C.

3.5 kW or 5.5 kW, one body

3.5 kW or 5.5 kW, one body

One housing is built as both power ratings, so a single line covers a market that asks for the light version and one that wants the strong one.

Water–electricity separation

Water–electricity separation

The element and the water path are kept apart inside a splash-rated body, with over-temperature, dry-heat and leakage protection as standard.

MOQ 1 pc

The sample price difference comes back

A single unit is charged above the bulk price, because of one-off handling and air freight. Place a bulk order for the same model within 30 days of receiving the sample and we refund the difference.

30-day rebate

Earlier shipments are rebated too

Our four price tiers — 10–99 / 100–999 / 1,000–9,999 / 10,000+ pcs — are counted cumulatively over the 30 days after you receive the goods. Reach a higher tier and we refund the difference on the units you have already shipped.
