4. Water heater description

The water heater switches on automatically as soon as a hot water valve at the tap is opened. When you close the tap, the water heater switches off automatically.

From the activation flow rate, the control unit regulates the correct heating output, subject to the temperature selected internally via jumper by a contractor during installation, and the current cold incoming water temperature.

If the water heater is operated with preheated water and the inlet temperature exceeds the chosen set temperature, the water is not heated further.

Fixed Domestic Hot Water (DHW) temperature

The water heater heats water as it flows through the unit.

The fixed DHW outlet temperature can be adjusted by a contractor via jumper during installation. The factory default value is 100 °F (38 °C). Other selectable values include: 110 °F (43 °C), 122 °F (50 °C), 140 °F (60 °C).

Heating system

The Direct Coil ^™ heating system is comprised of a pressure-tested, glass-reinforced polyamide heating chamber with a nichrome wire direct heating coil. It is suitable for hard and soft water areas and is largely insusceptible to scale build-up. The Direct Coil ^™ heating system ensures rapid and efficient DHW production.

STIEBEL ELTRON DHC Trend - Heating system - 1

Note

The water heater is equipped with an air detector that largely prevents damage to the heating system. If, during operation, air is drawn into the water heater, the water heater shuts down the heating output for one minute to protect the heating system.

The DHC Trend electric tankless water heater offers maximum convenience and accuracy when providing DHW. If you do need to operate the water heater with a thermostatic valve, we recommend adjusting the required set temperature on the thermostatic valve.

4.1.1 Following an interruption to the water supply
