Back Boiler - PRV

[Steve 130]

Hi folks, am in the process of fitting a back boiler to our stove and want to know If I need to fit a Pressure relief valve at all in the system. The system will feed three radiators down the length of the boat and also a coil through the calorifier with a standard header tank. The system will be pumped and this will be switched with a pipe stat to make sure we do not boil the water in the pipes but I am not sure if I need to fit a PRV on the top outlet of the boiler. Any help much appreciated.

Hi

I am not a plumber but if you have a header tank any high pressure will force it way out the breather in the top of the tank.

as a general rule prvs are fitted to the top of the clarifier
