Hi people
wondering if you could help diagnose my problem.
I have a Vailliant Eco Max Combi boiler, all was well until 2 weeks ago when I decided to change the radiator as my wife thought it was old and ugly
Whilst removing the rad I developed a small leak from the old thermostat. I called a plumber friend of mine who informed me the thermostat needed replacing, he then went on to shut of the central heating system but we still had hot water.
We had no heating for a few days until he returned and fitted new fittings on the leaking pipe and turned the heating back on.
This left me with heating and hot water but a missing rad which was supposed to be re-fitted from the plumber in a 'couple of days'
The next day I developed a fault with the boiler. F.25 no pressure. I topped it back up to 1.5 and a within a few hours it had drained again.
Ok, the house is covered with British Gas. Called them out and they came the next day.
The engineer re-filled the expansion tank? with air. Eventually he had a good look around and came to the conclusion that there is Oxygen in the water and need to top it up when the rad is re-fitted.
Here are the things I've checked my self; external overflow pipe, bled all the rads and checked for leaks (even under the floor)
My Radiator is being fitted Saturday morning.
I'd appreciate any help in diagnosing this problem as I'm not entirely convinced the oxygen in the water would lose 1.5 bar within a couple of hours.
Thanks for listening
