HI
Could someone please help?
I have a comb boiler installed in my Caravan Mobile Home and the Thermo Valve is leaking I understand that you have to drain down the system to replace this.
My Problem is that the system installed is pressurized and it contains Anti-Freeze for over the winter periods this allows me to drain down all the other water systems in the Caravan without touching the heating system. My concerns are how I go about replaceing the anti-freeze once I have fixed the leaking valve.
Is there some sort of kit I can purchase which allows me to get new Anti-Freeze back into the system and where would you pump this into? I expect it would be through one of the Rads?
Regards
Larry

My one is bucket, funnel, Hep2 O 15mm elbow+ 1/2 inch male iron adapter (hep) short stub of 15 copper with hose pushed over. then the funnel. remove screwed vent/ plug @ top of rad .-Screw in filler. (Hep fitting allows iron 1/2 inch fitting to rotate) set it up with funnel. Pour in mixture. Works well with the back tapped rads that are everywhere now.
