Converting Gravity Hot Water & Pumped Heating to Fully Pumped System

ADVICE on CONVERTING PUMPED CENTRAL HEATING GRAVITY HOT WATER TO FULLY PUMPED


Hi advice needed please, looked at a job recently which required a cylinder change due to pin hole. Currently the cylinder is heated by gravity 28mm flow & return going to oil fired boiler, and another separate flow & return on boiler for central heating. The current system does not have a room or cylinder stat, but has a programmer which appears to be able to heat hot water & heating separately!!! So not sure how this is wired up. So the new cylinder would require a stat but not sure how this would be tacked on to existing system and how to convert pipe work.
Thanking you in anticipation for your advice.

Steve

I'd forgotten about this - seen parts of it some while back. Spot of bedtime reading methinks ...
