After dumping an old rad in the summer our living room has only one radiator fitted, and now as the temps are coming down it is starting to get pretty cold!!
I used the B&Q BTU calculator and it said that for my room size I would need 9500 BTU/hour. The living room is pretty much the only heated room downstairs as the kitchen only has the boiler to heat it and hallway/downstair toilet have nor radiators. We have a large double glazed window and patio door, we also have laminate flooring so from this I decided that I would prob need more like 10 or 11000 BTU to keep the room warm enough.
The trouble I have is that I don't know what the output of the the existing radiator is. Can I guess it's output based on similar sized radiators, or as it is older will it be a lot more inefficient?
The existing rad is a double panel, double convector under the window 70" x 16". As an example I looked at a Stelrad double panel, double convector at 450mm x 1600mm so similar in size and that had an output of 7485BTU so would I right to assume my existing rad has an output of around 7000BTU and so I would need say another one of 4000 BTU to keep my room warm enough?
