It comprises a spring-loaded valve and a bellows operated temperature sensor. When a boiler flow temperature of 95ºC is reached the force exerted by the bellows system becomes greater than the force of the spring and the valve opens. Heated potable water then flows out and this is replaced by cold water from the supply network. This absorbs excess heat from the heat generator and prevents overheating.
