question for the plumbers

andydiysaver

hi - got a fairly decent boiler mounted at top of 3 floor house - only issue is it has one input output connection at present, so when you heat one set of radiators you heat them all


come winter, an attic guest room I have gets pretty cold. Already done the insulation job with celotex etc, but it needs heating to stay warm, reluctant to do that with any electric source, even a 400w mini panel as electricity is so expensive


would rather use gas, and to do that I'd rather put in a valve to split the output, so you can switch upstairs (top) and downstairs, or both- a splitting valve I think it's called


my question is this - and thanks in advance for input - how much would your average plumber quote on doing this as a reasonable quote, and also, how difficult is it to do it yourself? far more of an electric man -and although pretty good at most DIY stuff don't want to risk leaks etc, presume you have to either weld the thing in or otherwise? so weighing up pros and cons of doing job myself versus the market rate


any feedback welcomed.
cheers

Easy enough to do, would just need to add 2 x 2 port valves to split the heating to however you want it, then wire them up accordingly

It sounds like the radiator in the attic is insufficient OR the pipework is not insulated, meaning there is insufficient heat to the radiator by the time it gets all the way to the attic. However by the sound of it the boiler is near to the attic so heat loss should not be a problem.

The system might not be balanced correctly.

Please note that I am not a plumber or heating engineer so I might be talking B.S

If you are asking how to turn on the upstairs and downstairs rads independently all you need is a clear trv/thermostat valve on the one you wish to isolate in the attic
