Where is the filling loop on a ravenheat rsf820?
Basically im trying to get the pressure back into the system.
At the moment its turned off, does it need to be on when i repressurize it?
Sorry to sound stupid :)
Sounds like a similar problem to my boiler.
I located a small valve on top of the boiler similar to a dustcap and it was loose.
I retightened it but the pressure hasnt increased since, is there a way of re-pressurizing the system or should it happen naturally?
