Hi everyone
Apologies for basic questions but iv not done this before....
I have a combi boiler heating system I want to drain down to move a radiator downstairs.
1. Could I close all rad valves upstairs to save time/water draining and then only drain downstairs or would I be better doing it all?
2. I assume I cant use the boiler for hot water only if heating side drained?
3. I have an external (red) expansion vessel. Will i need to do anything with this when refilling?
4. Refilling is just a matter of opening the filling loop to 1 bar, then bleeding and rebleeding?
Thanks in advance
