Changing radiators - what do i need to think of?

fox1977

Hi there,

I have a couple of slim radiators that i am thinking of taking out and putting in new double (thicker radiators) as the rooms are a bit cold. I am also thinking of taking out a small radiator in the bathroom and replacing it with a towel rail/radiator.

In terms of the combi boiler, do i need to be worried about how powerful my boiler is (presure wise etc..)? If i put in a bigger radiator in one of the rooms is it going to cause problems?

It's probably worth getting some quotes first. I've done a fair bit of plumbing (amongst other stuff), but can't be bothered with the heating - 3 quotes, from recommendations if you can (gas fitters who do local landlords work are usually ok price wise).

Wookey

BTU/Kw output is what you need to worry about, i would imagine though that a small upgrade of 2 or 3 rads won't adversely effect you. Most boilers when sized should have some headroom.

Have a look at the "purno" (I think that's the name) semi slim ones - basically double radiator, but only one set of convector fins inside. They fit very close to the wall but have decent heat output ratings - they may be enough to give you the extra heat you need without invading your space too much.

Towel rails often give out less heat than a similar sized normal radiator - stainless steel ones although a lot more expensive are better heatwise than the cheaper white/chrome ones. You might want to think about having a dual heat one that has an electric element in it so that you can still have it on to dry towels when the main heating isn't on.
