[OT] well, sort of. Central heating radiator plumbing

[ian.bird@xxxxxxxxxxxxxx]

Hi all

I cannot find after a while Googling how central heating radiators are
typically plumbed in. I have a conventional heating system i.e. fully
pumped but not pressurised and I want to know how the radiators are
plumbed back to the pump.

I am trying to control my heating with much better accuracy, flexibility
and complexity (it is HA after all). To this end I need to know what will
happen if I turn off radiators seemingly randomly around the house
depending on individual room conditions. I am assuming at this point that
none of the radiators are plumbed from one into another otherwise when one
turns off then the water won't get to the next!!

Does a typical system have a manifold with individual feeds to each
radiator so turning one or more off won't have a dramatic affect on
others?

Any help with web links or other advice most welcome.

Thanks

Ian
