Function and Design

The DHW is controlled by a pressure and thermostat controlled regulator and a electronic regulating valve which registers the hot water flow. The district or central heating is shut off when flow of hot water stops. The heating circuit outgoing temperature is regulated with regard to outdoor temperature, via outdoor transmitter and control unit. An electronically controlled regulating valve adjusts the district heating flow through the exchanger.

Heat exchangers system of type Villauint for hot water circuit and domestic hot water circuit.

District or central heating side: strainer, well for temperature transmitter. Temperature and flow control valve for domestic hot water, BTU meter, and electronic valve for heating circuit.

Cold water side: shut-off valve, check valve, back flow preventer.

DHW side: thermometer, shut-off valve, transmitter for domestic hot water temperature, safety valve.

Heating side: pressure gauge, thermometer, control unit, transmitter for hot water temperature, outdoor transmitter (not mounted), shut-off valve, safety valve, fill valve, expansion tank, pump, and check/shut-off valve.
