Hi all
I have a problem with an old heating system. Our hot water cylinder needed replacement due to a leak and British Gas replaced it and all seem well until the pump packed in a few months later. BG replace that and from that time we constantly suffered brown hot water.
The system is a Parkray 401 (20 odd years old) with a back boiler feeding a new primatic cylinder. there are also 8 radiators.
BG claim the problem is due to the fact that the pump is too powerful for the primatic cylinder, which accounts for it happening just after the new pump was fitted, and the pump cannot be turned down to a level which will not "blow the bubble". They (BG) also claim there is not a pump available which is slow enough not to "blow the bubble".
Am I being fed a generous helping of BS by BG or is there a viable solution to allow us to get hotwater back into our radiators?
Help and suggestions of how to deal with this problem or British Gas would be appreciated
