new radiators in loft conversion.

[marlb]

Hi, I need to find a radiator for each of the two bedrooms in my loft conversion. One room has one velux windows and measures 35.2M3. The other measures the same but has two velux windows. I have used the BTU calculators on line but thought I would put it passed the experts on this site.

The calculators have come out with a figure of 810 watts/btu's. Does this seem about right? I am going to fit TRV's also. Any advice welcome...

Oversize a bit and use the TRV properly (not just left on full!). Easier to turn a big rad down than have an undersized rad with a cold room that you can't do anything with! If you have a condensing boiler then oversized radiators can increase efficiency too.

810 watts might be fine, 810 BTU will be chilly

Thanks for the replies. I missed a few details. The BTU's are around 2370 not 810. many thanks
