Just looking for a sanity check here please.
Been given a large towel rail and want to do a direct swap with the radiator in the bathroom, which will require lifting floorboards and adjusting pipes so they come out of the floor at the right location / fit some chrome pipe covers etc.
Central heating is a combi boiler, downstairs. Bathroom is upstairs.
1) Turn all radiators off, using the temp control on one side and locknut on the other. Make a note of how many turns to unlock to previous position.
2) Turn off combi boiler.
3) Drain systwm from the refil loop attachment. I'm guessing I only need to drain upstairs pipes and not entire thing.
Question: how will I know I've drained enough if only wanting to drain upstairs? Or should I let it drain completely to be sure?
Question: is it OK to use the refill loop fitting to drain from as I only need to drain upstairs? I can use the drain attachment on the lowest radiator but hassle re: proximity to actual drain.
4) Remove old rad / cut pipes / install towel rail. Have towels, bowls etc on standby for water left in pipes.
5) refill system until pressure is as it was. Go upstairs, bleed towel rail, go downstairs and refill system if desired pressure isn't met. Keep doing until it is.
6) turn on boiler and check heating works.
7) restore the other radiator settings to before I started
Sound OK? Missing anything? Advice?
Thank you!
Nb: I know a towel rail isn't a radiator. The rad I'm replacing is tiny and on its lowest setting and warm in winter with the window open, it's a warm room. The towel rail is 2m tall and happy with it giving minimal heat to the room as its not needed
