Sorry, didn't mention that i've set the pressure at cold at 0.8 bar, when the heating starts up the pressure slowly raises to over 3 bar and then water come out of the pressure release valve, when the heating is turned off the pressure drops to approx 1.7 bar then stays there. Troy

Hi guys. I have an Vailiant ecotec824 plus which keeps gaining pressure when the heating is switch on. A friend adviced me to change the main inlet service valve, which i have, and it's made no differance. Any idea's? Troy
