I have an open vent CH system and want to know if the following is possible.
If you imagine the rads connected to a boiler in a central heating circuit round the house. As it is open vented there is a small header tank in the loft. There are three pipes entering this tank namely 1) the cold feed TO the tank from the mains cold water, 2) the vent from the radiator circuit and 3) the feed FROM the water in the tank to the radiator circuit.
Question... The vent pipe rises up from the highest point in the radiator circut and loops up over into the top of the small expansion tank.
Is there any reason why the cold water feed FROM the F&E tank cannot be linked into the vent pipe just under the said tank?
