Before upsizing radiators I'd make sure that is the problem. Radiators are designed to operate at good flow temperatures. Can you put your hand on the radiator? Flow temperature should be up around 80 degrees. Is the boiler thermostat high enough? Is the system balanced? If you are getting that, do you have draughts? Insulation?

What Arthur says ^^

We prefer to supply our own prefered brand of radiators but will fit customer suplied products on the condition that we can only guarantee of workmanship.

Anyone who turn up and just fits a large rad should be avoided as there could be underlying reasons why the room isnt achiving its target temp

That's fine. Just didn't want you spending money pointlessly. I've seen it done a few times. Often modern systems are run with the boiler turned down as 'this is how our old one worked', but a fully pumped system should be running flat out. (This isn't always true of condensing boilers). So long as you have 80 degrees through that rad and it's not heating the room...it needs a bigger rad.

A radiator has to be 'output sized' to a room taking into account things like proposed use, wall construction, window size, number of external walls, volume to heat etc.

I remember my dad, now long retired used to use a disc type gadget like a round slide rule to calculate Btu (now Kw's I suppose), he reckoned after 40 years he could guess pretty close to the official number but it was always useful to check.

A decent plumber will no doubt do the same with his iPad now and you'll get exactly what you need and good quality rads are not wildly expensive either.

On a similar note, We have a room where the previous owners have removed a radiator. Is it simple enough to replace it and are they standard sizes?

Could be a breeze.....could be a real pain!

If they've left a standard valve on the pipes it would help as your new radiator will need two male fittings to go into them. With luck, a suitable width radiator with fittings will fit perfectly, all you'll have to do is mount the rad at the right height, open the valves and fill it up.

Life never being so easy means you'll need to drain the system to swap the valves for new ones and the gap will be an odd one requiring you to either amend the pipework or fit adjustable tails to the rad.

Which one's your money on?
