I want to change a radiator on my combi based central heating syste
WITHOUT having to drain dowm the system. I propose to use a freezin mixture on the inlet and outlet pipes and then put the radiator i place. (The old radiator has already been removed and the pipe temporarily closed off.) My problem is will the pressure of the combi system blow the ice plug before I can attach the new radiator? Any comments gratefully received Thank
