Replacing Radiator with Towel Rail on Vaillant system

[giveitagogordon]

Hi, I'm new to this forum but if possible, I would like some advice. I have a Vaillant Ecotec 837 combi and I am looking to replace a radiator in the upstairs bathroom with a towel rail. The radiator has an old valve with both inlet and outlet on the same side.
Firstly, do I need to drain the whole system? Id not, what do I need to do?
Secondly, once the radiator and valve are off, can I simply cut the existing pipework down to below floor level and thereafter extend it below the floor and raggle it up the wall with flexipipe to the new position?
Any help would be much appreciated. Thanks.

You are dealing with old microbore pipe though and need to know what you have under the floor 1st.
Yes, a drain down would be needed to the level of that rad
No, no flexipipe should be used.
You would need to get suitable sized pipe and have it extended properly, soldered ideally.
