Hi,
I have an existing oil fired unzoned central heating system. I have recently moved the boiler outside and want to zone it as shown in the attached jpeg, i.e.
Zone 1: Downstairs
Zone 2: Upstairs
Zone 3: Hot water tank
There is one pipe coming out of the boiler which tee's off upstairs and downstairs.
I have placed a motorised valve on the downstairs flow and want to know if I can just place the remaining two valves as shown, one on the flow into the tank and one just after it on the flow to the rads?
My only concern is that there is a loop arangement, hot water flowing into the hot water tank first, then out to the radiators and back to the boiler?
Is this how unzoned houses are / were piped? If this is the case what piping changes am I likely to need...a separate return from the hot water tank tied into the return line after all upstairs rads?
