Hi, I've a baxi back boiler downstairs & in the loft is a single hot water cylinder with an integrated cold one in the top of it. There is no other tank up there for the radiators.
When the heating is on I also get hot water. But when hot water only is selected the radiators upstairs also get warm.
I now want to move the bathroom radiator but i'm not sure how to drain the system? From reading this forum I believe I may have a primatic cylinder & am a bit worried about disturbing air bubbles etc.
Would it be better to leave the system full & try using a freeze spray while I connect the new pipes or is draining & re-filling my central heating a simple process.
