Removing a radiator - advice please

Thanks again, KjeIINN......another good suggestion.

Well, the job is done.

Took KjellNN's and others' excellent advice. Closed off all the rads, Drained off through the valves of the removed radiator (a couple of bucket fulls only), removed the old valves and installed the new, large towel-rail style radiator (very smart!).

Even fitted a drain-off valve below the rad in the downstairs loo.

Opened all the rads and refilled the system (keeping the pressure below 1.5 bar) and bled all the rads.

Result......no leaks and after a bit of balancing, the system works better than ever! Our study never used to get warm and now it's noticably warm. 

Thank you for all your great advice. This is what a good forum is all about! 

Good job done Ian. Thermostatic valves are liable to open on there own days later even when set to the lowest setting as I have found out,

Shouldn’t you use corrosion inhibitor when topping  up after a major drain down.??

Thanks Captain 

Yes, will add some now I know it's all working......although, only two buckets of water came out.
