So the blue dhw wouldn’t be passing also? I’ll order and replace the greyGrey cap
Morning @ianmcd
left boiler with cold feed on overnight and the pressure on the control unit gauge has risen out of the “green”. Is this all attributed to the PRV still or should I be looking at another valve to change same time as the PRV?
PRV is on order
Thanks @ianmcdIf you are changing the PRV you can just use the existing one to drain the boiler or use the drain point doesnt matter as long as whatever you use is left open as you pressurise the EV, the small ev will be for the cold water inlet you shoudnt need to touch it
Hi @ianmcd
PRV arrived today and just fitted it. The vent pipe outside is still dribbling water when I’ve set everything.
steps I followed : released system pressure, replaced PRV, leaving drain valve open repressurised the EV to 0.9bar. Closed drain valve.
opened cold inlet main feed. Opened filling loop inlet, then opened return valve to bring system pressure to 1.2bar. Closed return filling loop valve then inlet filling valve.
boiler on, hot water demand. Did get a fan error - is that cause the pipe work is empty for example? Any ideas do I need a procedure to get system going again?
think I didn’t set it all right after drain, got a fault code “too much air in system” - ?!
either way, still getting that venting dribble, take it only option is the heatx now?
yes can only be the Plate Heat exchanger now
