DHW instant production unit with electronic modulating regulator DESCRIPTION ECOSAN unit instantly produces domestic hot water by means of a plated heat exchanger. The control of the hot water delivery temperature is achieved by means of an electronic apparatus, with PID algorithm, which detects the instantaneous temperature thanks to the special probe, and acts on the system through the motorised 2-way modulating valve located on the primary circuit of the exchanger. The domestic hot water supply temperature can be changed using the keypad and the relevant display. When the production of domestic hot water is active, the unit electrically supplies a primary pump (optional) necessary for the circulation of the thermal heat transfer fluid inside the device itself. Domestic hot water production 35 kW and 50 kW power Electronic adjustment Optional primary pump DOMESTIC COLD WATER ECOSAN SOLID FUEL BOILER THERMAL SOLAR SYSTEM DOMESTIC UNITS PUFFER
