The temperature and pressure relief valve discharges the hot water contained in a storage tank when the temperature is over 100°C or when the pressure is exceeding valve set value
The valve closes when the pressure and/or the temperature decreases within the set tolerances
The valve starts opening at
a temperature between 98°C and 100°C
