Product detailsAPPLICATION: DEM suitable for DHW supply to one hand washbasin. International: Also suitable for showers with inlet temperatures above 20 °C. Operation with pressurised or non-pressurised taps possible.
EQUIPMENT/CONVENIENCE: Electronically controlled mini instantaneous water heater with control electronics, outlet temperature sensor and variable flow rate limitation. Accurate temperature delivery up to the maximum output. Internal temperature limit from 30 to 50 °C. Including special aerator for perfect water flow pattern and integral flow meter for fitting in existing taps (M22/24 thread). Anti-scalding protection for high inlet temperatures via automatic output adjustment. Suitable for oversink or undersink installation.
EFFICIENCY: Electronic output control for energy efficient and water saving operation. In conjunction with the control electronics, the outlet temperature sensor ensures the set temperature is achieved with maximum accuracy. For this, only the actual required amount of energy is expended; there is no need to add cold water at the tap. The water is heated directly at the draw-off point and only when required. Energy and water losses due to long pipe runs are avoided. This ensures maximum energy efficiency. Suitable for preheated water (e.g. in solar thermal and heat pump systems).
PROFI-RAPID INSTALLATION: PROFI-RAPID installation system for time saving, straightforward installation. Straightforward wall mounting: Secured at two points; back panel also serves as a drilling template; slots for compensating for drill hole discrepancies; appliance cover and internal assembly can be removed in one step. Fast, universal water connection: Metal water connections and 1/2" adaptor supplied for direct, universal installation of taps. Easy electrical connection: Power cable prepared for permanent connection as standard. Protection rating IP 25 (hoseproof). Fault analysis with LED diagnostic traffic lights.
SAFETY: Maintenance-free bare wire heating system, suitable for hard and soft water. Safety system with high pressure switch and electronic temperature monitoring.
