New radiators

raddy59

I have bought a few new radiators using the newer convection type, and I think they are so much better than the old clunker ones i used to have.

ANyhow, so far I have only installed single panel ones, now I have to put a new rad in the hall which is quite a cold place. I definitely think the new rad will make a difference, but can anyone tell me if a double rad will be that much better (wearmer) than a single to justify the higher price?

I think? the answer the the BTU's the radiator has, not the size of rad..? I'm sure there is a website somewhere that can advise btu's or ask in a local plumbers shop? Sorry, thats all I can think of.

I'm having c/heating installed in couple of weeks and know our central heating guy has accounted for some radiators hes supplying being double rads.. I'd rather be too warm than too cold.

My thoughts exactly.

I'm replacing the radiators in my house nd have ordered them for fitting by my builder. He doesn't understand why most are doubles. I figure I'm not likely to replace them again for at least 10 years (fingers crossed) so I may as well make sure I won't need to.

My builder thinks the doubles will take up too much room but that's the least of my concerns

For a very rough calculate room size in cubic metres and for a hall multiply by 144. If its a very modern well insulated house reduce that figure to 120 and if its a very drafty room with outside walls and a lot of glass increase it to 160.

The figure you get will be the BTUs required. For a more accurate calculation do a google search for online radiator calculators. Try here (sorry not allowed links as a new user)

If you buy decent radiators you should be able to get a 10 year guarantee. If you buy cheap and nasty then the guarantee will not be as good.

I always think its better to oversize than undersize and then fit a TRV so that the heating costs are controlled

I would check if your internal walls can hold a double rad double convector, I only say this as I was going to put a double rad double convector in my hallway, when the rad came it was about 40kg and that was without being filled with water so internal wall could not hold it, plus it would of stuck out about 6 inches from the wall. So instead I got a larger single rad single panel that fits better for BTU required for the space.

I got mine from toolstation however I later discovered plumbworld had the same for slightly less (nevermind). Plus I installed them myself - so I've saved a bit trying to get a plumber. (not bad for a woman!)
