Thermostatic valve assembly and method for controlling the temperature of the hot water in an integrated sanitary plant, with solar panels - modulating gas-fired boiler

摘要

A thermostatic valve assembly (14) and a method for controlling the temperature of hot water in integrated sanitary plants, comprising a solar water heater (10, 12) and an instantaneous modulating gas-fired boiler (17). The valve assembly (14) comprises a thermostatic flow diverter valve (D) which, on reaching a threshold temperature (TS), automatically diverts hot water from the solar water heater (10, 12), directly towards a main thermostatic mixer valve (M) supplying a sanitary plant (16), for temperatures (T1) exceeding the threshold value (TS), or indirectly towards the instantaneous boiler (17), for temperatures (T'1) of the water of the solar water heater (10, 12), lower than the threshold value (TS); a thermostatic control mixer valve (C) reduces the temperature (T4) of the hot water entering the modulating boiler (17), to avoid switching-on commutations and irregularities.
