Hi all. Usual thing, existing floor standing gas boiler is pumped for CH and running into a 28mm cylinder coil for DHW.
I am planning on capping off the CH flow and return at the boiler and converting the system into a y-plan fully pumped system.
Question for all. I realise the pipework is in 28mm for decent circulation by gravity. Is there any reason why I can't fit a 22mm y-plan kit then just use a 22/28 reducer after the valve to connect on to the existing 28mm?
I can't see a problem with this but wanted to check with people who have more experience of doing this than I!
