Heating Performance and Technical Information

The DHE Set Comfort range heats water instantaneously as it flows through the unit. This ensures hot water is available only when required, significantly reducing energy waste compared to stored systems.

The DHE 18 21 24 Set Comfort model offers selectable output ratings of 18 kW, 21 kW or 24 kW, allowing installers to configure the unit according to site requirements and available electrical supply. This flexibility makes it ideal for standard domestic bathrooms, en suites and kitchen sinks.

The DHE 27 Set Comfort provides a higher 27 kW output for properties with increased hot water demand or where higher flow rates are required. This makes it particularly suited to larger bathrooms or simultaneous draw off situations.

Both models operate on a 400 V three phase supply and use Stiebel Eltron’s 4i electronic control system, which continuously adjusts output in response to inlet temperature and flow rate changes. This ensures stable outlet temperatures even during fluctuations in water pressure.

The intuitive digital display provides real time temperature information and allows users to quickly access pre set comfort settings. ECO mode helps optimise electricity usage while maintaining performance.
