hi there,
So my CH is an Vented system. I want to install UFH into a new extension. Rather than plumbing into existiting secondary flow and return for rads, I’m told the best way is to create new flow and return control with its own motorised valve.
To avoid the pumped return spilling into the header tank I believe there’s something about the positioning of where the new flow and return intercepts the primary flow and return that is crucial.
Any clarity on this would be much appreciated.
Secondly, if I wanted to replace my header tank with one of those with a diaphram making it sealed, how much pressure does the system work under. Seems to me that it would only be marginally more than a gravity fed system.
Thanks for Any help given
