The stainless-metal spring exerts only a little drive to close the valve, as a result only a little excess weight of drinking water is needed to open up the valve. As a result the better the circulation of drinking water the greater the valve will open up, performing as a visual fault indicator.
A second thermostat incorporates a thermal Slash-out which switches from the immersion heater and shuts off drinking water from the boiler if the Regulate thermostat fails and temperatures get to among eighty five-89°C.
