    Singing noise related to water pump

    Since our central heating system was upgraded in October we have noticed a singing noise in the house when the water circulating pump switches on. It is a new Grundfos UPS2 15-50/60 pump with 3 speeds. Reducing the speed reduces the noise but it doesn't go away, and we need to use the maximum...

    Hello I have a Glow worm fuelsaver Mk II 30B which runs 5 rads in a two storey house, and an indirect hot water cylinder. There is a lot of pipe work because the boiler is a long way from the hot water cylinder, although this may not be relevant I suspect the boiler is gradually scaling up...
