Grundfos Alpha1 15-50/60 B Domestic Circulating Pump 99415672

Saw this on Amazon Warehouse at a really great price. Bought it for the said great price. Happy customer. This is a really quiet pump and only draws 4w when pumping hot water around my central heating.

You only know what you’ve put up with once you try something new, be it enforced like this case or for economic reasons. It’s easy to fit easy to use snd so quiet too don’t waste time looking for anything else excellent value

This is the new EU type of pump - meets the new low power input requirements - almost silent, cannot be heard more than 1 meter away! Took 20 mins to replace old pump. At the £95 price v's Retail £225 now can you go wrong. I researched pumps for 2days - so I can recommend this one without dought - it has a 5year warranty v's others usually of two.

Perfect modern replacement (like for like) as also recommend on the Grundfos technical webpage.

This is the second one of these I have bought.Modern pumps are just brilliant!My old pump consumed 100W continuously when the heating was on. Doesn't sound much, but the electricity cost mounts up! The Grundfos consumes on average 8W. That is a terrific saving.They have a nice plug fitting which makes then really simple to swap out if they fail.Arrives with the plug and some washers. Direct replacement for most pumps.There are three types of system with three power settings for each one of the three. The three are Constant Pressure, Proportional Pressure and Constant Curve. The pump comes preset to Proportional Pressure II. Which is the recommended setting for most central heating systems. Beyond that you need to refer to the main product manual on their website to check what setting you need.I changed mine to Proportional Pressure I and it worked fine, which saved a few extra watts.Highly recommended.
