great forum
My boiler loses pressure only when the heating is running the pressure does rise but i have not let the prv release the pressure i have done it myself.
after reading this i am assuming that it is the expansion vessel look an average job to replace. Is it worth checking the pressure in it myself and is there a way to confirm it is U/S.Is there any thing to look out for when i change it. (never run right since the "bosch engineer" serviced it)
