Re: Convert gravity system to fully pumped
Are you saying the system in question is
'designed well, incorporating the correct valves, and pipe sizes, and switch controls.'
to allow two pumps to be fitted,if I thought it was ,no problem,but I do'nt and think that there is a possibility of one pump being burnt out by the other,although the flows for heating and hot water are seperate
,the cast iron heat exchanger on the hide away is not very big and the pumps will fight each other,which if you contact golw worm they will confirm
Also it is not doing the customer any favours as when the time comes to replace the boiler the system will still require up dating correctly,with zone valve/valves making second pump work wastefull
