Barberi® V20 thermal solar kit is used to control the hot water temperature. Its function is to maintain constant the temperature of the domestic water sent to users, even if hot or cold water inlet temperatures or pressures vary.
Moreover, the kit allows to manage the domestic water coming from solar storage or other devices able to pre-heat the domestic water. Through the diverting valve, the water is sent directly to the thermostatic mixing valve (if the temperature is higher than 45 °C) or sent to boiler for the thermal integration (if it is lower than 45 °C). It is normally used in domestic water systems, in thermal solar systems on the DHW flow of the storage in forced or natural circulation systems.
