My pump has got noisy, it's 35 years old. I propose to replace it.

I'm wary of circulator pumps in the £20-£40 range. Has anybody tried
the CBS Intel 15-60 130, about £70, which claims to be A rated [Though
it seems odd to worry about 50 watts when you are burning 20 kilowatts
of gas.]

The Grundfos competitor seems very expensive, but I expect it's better.
