Hot water cylinder coil balancing and connection questions.
Posted: Tue Aug 14, 2007 10:35 pm
I'm fitting a new hot water cylinder (vented) fed from a condensing boiler.
My old cast iron (Ideal Concorde WCF) boiler fed the old cylinder.
Two questions:
1 The old system had a gate valve on the return from the coil, presumably to 'balance' the circuit.
All new system diagrams I've researched recently don't show this valve - does this mean I don't need to fit one?
2 My old system had the feed in at the bottom coil connector and the return out of the top coil connector - not sure why - doesn't sound right to me - better heat transfer if the other way round sounds best and current diagrams back this up?
Thanks in advance for any advice,
Col
