Hi All
Well I bought this house in Brugge and the central heating is a bit on the old side, cast iron radiators and the house has 2 systems with 3 boilers, here's the problem.
The first system is now working OK but makes a terrible noise when running, sounds like air in the pump which seems to vibrate throughout the whole system, I've spent hours bleeding the pump, system running and system not running. The pump is a Grunfos UPS 200, big pump I know but it's a big house my question is about the size of the feed pipe to the pump, at some time in the past the pipework has been changed and the pump is now feed by a 1" iron pipe, considering the size of the pump is this big enough and could this be the cause of the noise problem ???????
Any help would be most appreciated.
Thanks
