hi all,
i am in need of advice re ch system.
My house has a simple gravity feed ch system with gloworm fuelsaver f boiler. I reckon its about 20 years old.
I had some building work done in the summer and a radiator was removed temporarily and then replaced. I turned the system on last week and the radiators will not heat up.
I have hot water and the boiler and pump appear to work .
I have bled each rad and removed lots of air but still no heat. When i bled the rad nearest the boiler it temporarily warmed up ( warm water entered via the non return valve but not the normal thermostat valve) and then went cold.
I have a drain tap by the front door which i opened and drained slightly, the same thing happened with the rads nearest the boiler; heat entered 'the wrong way' into the rad and then went cold.
I am going to buy some cleaning agent and add it to the tank in the loft and then drain the system.. but am slightly unsure as to what this involves.. other wise i don't have a clue what to do... it was all working fine last winter...
