I have what appears to be a conventional central heating system, heated through a Potterton Prima Gas Boiler. The pump feeds into a 3 port divert valve feeding rads and hot water tank. There is a bypass between the pump and the valve.
The system is vented on the feed from the boiler and the hot water tank and so what is the purpose of the bypass, as the valve can never be closed.
The heating system does not operate effectively in as much that periodically one of the downstairs rads goes cold, not air as this has been checked many times. The problem is worse when the outside temp is very low. My theory is that the bypass (open) is reducing the flow thro the system and the how water is not reaching this one rad, which is the farthest from the boiler.
The system has been looked at by a plethora of plumbers but the problem remains.
Any help to stop my fanily freezing would be apprecaited.
