Additional CH radiator - joining to flow/return pipes

sgoode

Hi,
I want to put a radiator in my kitchen where currently there isn't one. The kitchen has a solid concrete floor so running pipes will be difficult. Would it be possible to run the pipes to the new rad from the bathroom directly above as I could run them behind some kicthen cabinets? Or should the upstairs and downstairs circuits remain separate for balancing? If it makes any difference the boiler is upstairs and it is a combi.

The flow and return pipes running from upstairs to downstairs are within a stud wall which is actually one of the kicthen walls. However the old lath and plaster has been plasterboarded over at some point and to hack all this off to locate and join to the pipes would make a right mess. But would I be best off doing that?

Thanks for looking.

No need to keep upstairs and downstairs separate. Balancing is by radiator, not by floor. However, a bathroom rad tends to be small and might just be tacked on in an easy position but with a high resistance path. If thta is the case, your kitchen rad could be a rad too far. Take a look at the circuit to the bathroom rad before deciding.

If you have a vented system and the bathroom towel rad is on the primary circuit you shouldn't do it the way you have suggested IMO.

Edit - Oops sorry you've got a combi so the paragraph above doesn't apply but I'll leave it there for anyone else who happens on this thread and does have a vented system. DVS is correct. You may get poor performance your way but then again thats one reason to employ a plumber innit?

Cheers
