My 10-year-old Grundfos 3-speed central heating pump is getting a bit
noisy, and I intend to replace it in the near future. Since I also intend
to fit TRVs to most radiators next summer, it would make sense to fit a
pump whose delivery is automatically variable, and I have been considering
getting a Grundfos Alpha.

In the latest Screwfix catalogue (#80) I see that they're selling Wilo
Smart pumps - which appear to do more or less the same as an alpha - for
45 quid, which is not much more than half the price of an Alpha.

Does anyone have any experience of the Wilo (pronounced Vee-Lo according
to their website) pump? Is it any good? *Does* it do the same as an Alpha?
[From the picture it looks as if it may have less scope for adjustment].
Is it a case of "you gets what you pays for" - or do you pay through the
nose for the Grundfos label?


Hmmm - no direct knowledge of the Wilo, but I fitted a Grundfoss Alpha about
2 1/2 years ago.

The Grundfoss has an infinitely variable speed and a green LED which tells
you its on - apart from that the specs seem similar.

Very pleased with it - the big advantage is the lack of noise as it auto
adjusts the flow rate depending on demand - it is so quiet in fact that
during the recent cold snap I can leave the pump on overnight and not be
disturbed by any discernable rad/valve noise.

As a point of interest I paid £66 inc. vat for it at my local plumbers
(full, not trade price) then.
