Thanks scruff, I calculated my radiator BTU's using standard requirements on online calculators, all rooms equated to 40K btu. Have cavity insulation and 270mm in the loft, all relatively new double glazed.
All advice online for a 4 bed detached seems to point towards 35-42 KW bolier, and that's why I'm confused as my BTU totals to 12KW?? Will have 13 radiators by my reckoning. Kitchen, Lounge x2, hall, Dining, Family, x4 bed, x2 ensuite, bath.
Just to make sure I'm correct, when using the online calculators, i do match the results for each room with that of the radiator output? Cheers
