I just need some heating advice.
We mainly heat our house with a woodburner in the sitting room
(space heating only, no backboiler)
I've had a new gas combi fitted which will heat an underfloor heating
system in our kitchen/ dining room. The underfloor heating is working really well and is only needing 28 degrees output on the boiler.(at the moment! )
I'm in the process of specifying 4 double panel convector radiators (2 up and 2 down), and have chosen their k.w outputs based on the 50 degrees output specified in the catalogue. (a 1.6, a 1.4, a 1, and a 1 kw.)
My question is;
Is there any benefit in over sizing the radiators (by say a factor of double the 50 degree size ) so that they can run on a lower boiler heat output ?
(And therefore save on gas consumption); And maybe even run at the same low output as the underfloor heating circuit ? so that I can set the boiler temperature at the low output for both circuits (the radiators and the underfloor heating).
I do have a mixing/blending valve/manifold on the underfloor heating circuit so this can blend down the boiler temperature to the correct lower temperature, if they require different temperatures, but is this efficient ?
the boiler running higher (say 50 degrees) to feed the radiator circuit and then having to be cooled down to 28 degrees for the underfloor circuit.
Would it not be more efficient to have the boiler running at the same lower temperature for both circuits ? Hence my question about doubling the size of the radiators, and can a larger radiator run at 28 degrees anyway.
If you have any helpful advice, it would be appreciated,
