Small instantaneous water heater 4 kW unpressurised

Unpressurised instantaneous water heater for single draw‑off points with instant hot water supply.

The compact instantaneous water heater is permanently connected to the supplied special fitting and reliably delivers hot water to washbasins or sinks. As soon as the hot water tap is opened, the unit starts automatically and heats the water directly as it flows – with no pre‑heating time and no storage tank. This means energy is consumed only during actual use: no waiting time, no unnecessary losses, and noticeable energy savings in everyday life.

The non‑insulated heating element ensures instant heating and is designed so that even with very hard water, no limescale deposits can adhere. Blockages caused by limescale are therefore a thing of the past.

Depending on the desired temperature, the hot water supply can be regulated or cold water mixed in. In winter, a reduced flow rate helps to achieve pleasantly warm outlet temperatures even when the inlet water is cold.

For optimal results, the supplied special aerators are recommended – helping you get the maximum performance from this compact powerhouse.
