Why this model

Black or white, from stock

A narrow arched face that leaves room for a mirror on the same wall — the two colours buyers ask for are already in the warehouse.

190 × 70 × 305 mm

190 × 70 × 305 mm

Narrower than a standard tankless body, so it mounts beside a basin or a mirror without taking the wall.

Three seconds to hot water

Three seconds to hot water

Test one unit before you commit to a container

Every model is available as a sample, and every price step you reach is paid back to you — the sample itself included.

Order a single unit to test it, open it up and show your own customers. No minimum quantity, any model in the range, shipped with its CE and RoHS test reports.

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.

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.
