hi all,

can anyone tell me if I need to remove the pump and condensate trap to replace the dhw heat exchanger, or is it possible to do without

thanks in advance

thanks for the reply

I like how the manual stated maybe lol!!

im a self employed spark by trade for over 30yrs work away a lot alongside a plumbing company, so we help each other out a lot as we both know each others work .....unfortunately he's still away till end of month (sods law really)

wasa thinking on leaving it till then but got the bits so was going to do weekend

problem I got is the pressure is at just under 3bar the prv is keeping it at this as it is leaking, the pv has 1 bar in it so don't suspect this and when not calling for ch or hw pressure goes up unless I turn of the cw supply
