Hi
Getting the correct btu calculation drives me mad. For the current job mentioned below I've used b&q. hlab, radcalcs.com all with different results, so which of these calculators would you advise.
I've slowly replaced the radiators in the house but never 100% sure whether I've got the correct size. In some forums they have recommended the B&Q calc but I'd like to double check.
The Job
I'm replacing an old double rad (H750mmxW900mmx55mm) in the kitchen (4.4m x3mx2.4m, north facing, 2 outside walls, wood floor,double glazed,no french doors). The boiler is in the kitchen as well.
plus
I'm replacing an old double rad (H450mmxW2100mmx65mm) in the dining room (4.4mx3.7mx2.4m,south facing, 2 outside walls, wood floor, double glazed, no french doors).
New replacements:-
I'm interested in the stelrad compact style vertical P1 to replace the kitchen radiator (H 1600mm x 500mm (3642 btu)) this is due to change in wall space and Compact style horizontal K2 (H300 x 2000 (5930 btu))
in the dining room.
many thanks
