Getting a larger radiator

WestCoast2017

Our sitting room is larger than the other rooms in the house, and its north facing with a large window. Its always cold. Is there any benefit in getting a larger radiator? Would it give out more heat or just the same heat on a larger area?

Generally the bigger the rad the more heat output. If this is the room you are in the most I definitely wouldn't be happy if I wasn't warm. Apart from a higher output rad you could look at interior insulation. This wouldn't be too expensive for just the one room.

The house has the cavity pumped. I think the coldness is largely the north facing aspect and the size. I think we would be in there more if it was warm :-)

We nearly never heat upstairs and the radiator in the kitchen is turned off (TRV) so its not like the rest of the house is cold.

Pumping a cavity block is a waste of money. If you have a cavity between the blocks then it's a good insulation.

If the rad does not heat the room to a comfortable level in the depths of winter then I'd be looking at a bigger rad.

You can increase the rad output without taking up the more wall space. You can go from single to double or even double to triple

Is the existing rad getting too hot to put your hand on it? Is the bottom centre also very hot?

The rad is uniformly hot, but its not too hot to put your hand on.

What's your heating source, is it a condensing boiler? What is boiler stat set to? What is room stat set to? Have you zoned heating? Type of windows? Attic insulation?

Lots of questions, I know, but exactly the same as I would ask any householder before making any recommendation.

Condensing boiler
Don't know what the boiler is set to. Its an 18KW boiler.
House is zoned with mechanical valves
Double glazed windows
Attic fully insulated with thick insulation
BER is C1, house is about 18 years old.

Two wireless stats, set to 21 degrees, but in the hallway and landing

Turn whichever stat controls that room up to 25 for an evening and see if that radiator gets much hotter.
