Boiler....

[theelziebub]

Hi everyone,

We're having a new boiler put in, and the company is telling us they need access to all the radiators in the house, the only problem is, one of the raditors is completely inaccessable.

Does anyone know if not being able to access one of the radiators will make a difference to the new boiler, or mean we can't have it fitted?

Thanks all xox

only a wild guess,

but i think when you replace a boiler you have to drain the water from the system, then install the new boiler, then fill up again, which in turn causes pockets of air to be trapped within, this air is released by the use of bleeding thingies on the radiators, so i quess that if you leave one rediator with air in and and not bleed the air out of it properly then the circulation of the whole system may be affected.

If they turn the rad off on both valves before they drain it, then no water will be lost out of that rad.

if you are updating as is likely say to a combi or condensing you are changing systemsi.e. lose the feed/expansion tank in the loft and the cylinder in the airing cupboard
so the existing system will be subject to mains pressure on the rads and pipework.what if this rad can,t take it? and starts leaking.you will have to find a way to stop it
also how can the system be balanced correctly w/o access to all the rads
if this rad is inaccessible how does it emit any heat or serve its function? good luck
