Overheat Safety Valve

This valve measures the temperature in the woodburning boiler stove.  If the temperature reaches 97C inside the water then the valve will open and flush cold mains water through a quench coil.  This will collect the heat from the boiler and disperse it safely outside.  This valve MUST always be fitted to a woodburning stove that is installed on a pressurised system.
