Water Heater DEM 4

Application • The electronically controlled mini instantaneous water heater supplies DHW to one hand washbasin. • Operation is possible with pressure taps or non-pressurised taps.

Convenience features • The appliance has control electronics and an outlet temperature sensor. Variable flow rate limitation is possible. • The preferred temperature can be set accurately up to the maximum output, an internal temperature limitation is possible. • Standard delivery includes a special aerator, which optimises the water flow pattern in existing taps. A flow rate controller is integrated. • Both oversink and undersink installation are possible.

Efficiency • Electronic output control for energy efficient and water saving operation. • There is no need to add cold water at the tap. The outlet temperature sensor and control electronics ensure that only the amount of energy actually required is used to achieve an accurate preset temperature. Energy and water losses due to long pipe runs are avoided, as the water is heated directly at the draw-off point and only when required. • The mini instantaneous water heater is also suitable for preheated water from solar thermal and heat pump systems.

Installation • Time saving and easy installation ensured with the PROFI-RAPID installation system. • Straightforward and quick wall mounting with 2 point attachment. The back panel can also be used as a drilling template, the integral slots enable compensation for any drill hole discrepancies. The appliance cover can be easily removed, the internal assembly can be removed with just one hand movement. • The external metal water fittings allow quick and easy installation of the taps. • The electrical connection is simplified by a power cable wired up as standard. • LED diagnostic traffic lights are integrated for fast fault analysis.

Safety • Automatic output matching protects against scalding at high inlet temperatures. • The maintenance-free bare wire heating system is suitable for hard or soft water. • The appliance has a safety system with high pressure switch and electronic temperature monitoring.
