Central Heating Question

Ease of changing old radiators to new? carpets coming up?

I ve just bought a flat, orignally I had nt planned to change the very old radiators immediatly but as carpets will all be coming up, and original floor boards can be unscrewed I wondering how much easier would it be now? Budget is small if I could do once new carpets down it would be preferable? I need 5 changing (which are £10 each) how exact will the sizes of the new ones be matching up to old? I know system has nt been touched in over 15 years so potentially the different imperial sized pipes? If a ballpark figure of cost/ time could be given that would be great, I know its difficult?
Secondly I m also thinking i would like a second radiator fitted into the lounge. I know this would require new pipes, floorboards up etc; but wondering if my boiler not currently up to it (dont know how i would tell?) could I get it fitted could it be turned off from the system until boiler upgraded.
Thanks in advance of any advice.

Generally your old rads will no doubt be imperial if 15 years old. These can be replaced with metric but will require pipe work alterations under the floors. Its advisable to do this prior to having the new carpets fitted, as they will cut carpet to suit pipes coming through floor and these pipes will have to be altered to fit new rads. You can of course try and source imperial rads but this can be difficult and costly and also you will not get much choice in rad style. Adding another rad should not affect your boiler but this depends on the kw rating of the boiler. If your boiler is a combi it will be no problem but if you have a conventional system you need to get the kw rating of all existing rads and add 3kw for hot water and subtract this from your boiler rating, what figure you have left is what size rad you could add on to the system. All work carried out would take no longer than a days work for a pair of fitters.
