Hi all,
I'm after some advice please on adding a zone to our existing central heating system. I'm quite confident with plumbing itself, and the wiring involved, but i have a few questions that i hoped someone might be able to answer for me.
The boiler is a 2006/7 Ideal c24 mini HE combi.
I would like the existing main heating circuit to be independant of the room that the new rad is going into.
Ideally, I would fit 2 x 2 port valves, however my concern is that as the valves would be mounted on the pipe work about 12inches below the boiler, and if a bypass valve is required, this would be too close to the boiler to be effective if the boiler is over running and both valves are shut. Am I correct? Does anyone know if a bypass valve is required with my boiler? We have a permanently open rad on the existing circuit, but this isn't a lot of use is the zones are closed.
As a way around this, i thought about a mid 3 port valve which i understand are normally used to control a CH/HW system. My logic being that water will always be able to flow through at least one of the ports if neither zones are calling for heat. Can a 3 port valve be used in this way to control 2 CH zones instead of 1CH and 1HW zone?
Thank you in advance.
