I want to have 2 radiators replaced with different sized/shaped ones.
As the valves will be going, do I have to empty the system?
Someone told me there is a switch gizmo on the boiler to enable that but it doesnt seem possible to me
BTW one of the rads is ground floor, furthest from the boiler. Surely gravity will force the system to empty ?
