Hi
I've had an extension and have decided to replace the whole of the CHS, not that there was much there in the first place (only a smallish house). My hand has been forced in a way by the new Building Regs, however I do think it is a good idea.
I am installing two heating zones (upstairs and downstairs). I understand that for the flow I have one 22mm flow from the combi and then this gets split into two 22mm pipes, one for radiators upstairs to be connected to and the other for the downstairs radiators, each with a motorised two port valve allowing them to be controlled by a programmable room thermostat.
However, my question and I'm sure there will be many, is do the "return" pipes have to be seperate as well or can all the radiators, upstairs and downstairs be connected into the one return pipe or does this have to be seperated as well??
Any diagrams would be absolutely brilliant...can't find any on the net for how the pipeing is layed out.
Any other tips such as limit on length of pipework, limit to number of radiators would also be highly appreciated. BTW...I'm using 22mm and then teeing off to the radiators using 15mm, all HEP20,
Cheers
