  • Product details

    APPLICATION: DHE Touch is suitable for supplying DHW to several draw-off points (single and group supply), e.g. simultaneous supply to bathroom and kitchen. Sealed unvented, pressure-tested appliance for use with all commercially available pressure taps.

    EQUIPMENT / CONVENIENCE: Instantaneous water heater with full electronic control using 4i technology. Guaranteed accurate temperature delivery at all times thanks to electronic flow meter. Temperature selection via touch display and touch wheel, variable temperature setting from 20 to 60 °C in 0.5 °C increments. Self-explanatory operation via graphics-enabled touch display. Function symbol size and arrangement individually adjustable. Up to 12 individually programmable temperature memory keys (memory function). Wellness shower program, automated bath filling, timer program. Scalding risk indicator at temperatures above 43 °C or when preheated water causes unexpectedly high outlet temperatures. Individually adjustable temperature limit (childproofing). Mini wireless remote control. Removable programming unit can be used as a wireless remote control and positioned independently of the appliance: as a freestanding unit with mains plug, directly onto a flush box or into available socket frames (see optional accessories). Pivoting appliance cover and programming unit for increased operating convenience in undersink installations.

    EFFICIENCY: Energy and water savings of up to 30 % through electronic output control with 4i technology. 3 sensors and an additional motorised valve ensure accurate temperature delivery. For this, only the actual required amount of energy is expended; there is no need to add cold water at the tap. This ensures maximum energy efficiency. Graphic display of consumption and costs. ECO mode can be individually selected for particularly economical operation. Savings monitor gives details of savings actually made and further possible savings. Suitable for preheated water (e.g. in solar thermal and heat pump systems).

    PROFI-RAPID INSTALLATION: PROFI-RAPID – the improved installation scheme, for even quicker and simpler installation. Easy replacement of all conventional instantaneous water heaters.
