8.8 kW Instant Electric Water Heater — Touch and Knob Control, Copper Water Ports

An 8.8 kW point-of-use heater for markets where the supply can carry it. The stainless steel cup element brings water to temperature in about two seconds, the LED shows the live outlet temperature and a combined touch-and-knob control holds it between 30–55 °C. Copper inlet and outlet, no plug — it wires straight into a 40 A leakage breaker that comes in the box.

Why this model

High power without a storage tank

What importers ask first on an 8.8 kW point-of-use unit — answered on the page.

8.8 kW, two seconds

8.8 kW, two seconds

The stainless steel cup element sits in the water path, so heat reaches the outlet in about two seconds and nothing is stored to cool down between uses.

Multi-point water supply

Multi-point water supply

One unit can feed a shower plus a basin or kitchen point through the copper outlets — useful where a second heater would otherwise be needed.

Sized for wall retrofit

220 × 88 × 360 mm and a 2.0 kg unit. The compact body fits bathrooms where the wall space and the pipe positions are already fixed.

IPX4 body, no plug

IPX4 body, no plug

Splash-rated body with water and electricity kept apart. Ships without a plug for direct wiring to a 40 A leakage breaker, as the local code usually requires.
