oil central heating boiler

Postby trevkit » Wed Aug 18, 2010 4:44 pm

I have to move a wocester oil combi boiler to another room, am I right in thinking that its electric off, oil off, water off then drain from the bottom of the boiler?there is 2 drain cocks do I drain from both? It looks like the 22mm pipes at the back will remove ok with one needing cutting, what will happen to the water in the radiators? do I have to drain everything?

Close all radiator valves then drain the water from the drain cocks until it stops running.
