Do I need to drain my system...

[dave73]

to change a radiator?

I have a combi boiler and can adjust the pressure without problems and presumed I would need to drain before I change a radiator, but I would need to lift the floorboards to find the valve and I was wondering if this could be avoided.

Thanks for any help, Dave

Must be murder turning the heating down, turn off valves each side of rad, crack nuts & drain rad, remove, refit new, not as simple as that but that`s the general idea.

if the new rad is exactley the same width as the old one, then this is not a difficult job. Make sure you calculate the height correctly for the brackets to match pipes. If diif size rad then call experienced person to make neat job.

No you don`t close down valves on either side of radiator, thereby stopping flow or return from pipework. Empty radiator with a little dish or whatever & remove. refit new rad, attach exisisting valves then open and bleed rad.
