Easy fit and quiet pump Last pump only lasted 2.5 years before getting seized up. Could not get it to start and it has suddenly got very cold out. Needed emergency fix so took a risk and got this same make and size from Screwfix. Took 10-20 mins to fit, comes with rubber washers. Had to buy pump pliers but well worth it. Would help if the website shows dimensions. Overall seems excellent, very quiet pump which was worrying at first as I wasn't sure it was on until downstairs radiators started warming up. Works out much cheaper and faster than calling a professional at this time of year. (xmas/new year week). 27 Dec 2014
Great product Bought one of these for each of the houses we have had and have just fitted one to our new house. Works really well, and is getting all the rads hot what's really good it when just one or two rads needs heat they now run quietly. Great product 23 Nov 2014
Replacement CH pump My old Grundfos CH pump had seized after 17 years of faultless service. The new Alpha 2 L was a straightforward replacement and the use of a plug at the pump end of the flex made it a lot easier to wire up than the old one. I'm using it in "proportional pressure" mode where it should adjust its speed to provide just the flow required, and it seems to be doing just fine; gets heat to all the rads at startup but when only one rad is on there is no excessive noise at the TRV or pump. As for reliability, I can only base this on the 17 years I got out of the old one. The only negative is the instructions; all pictures, no words. Hopeless in understanding the modes of operation. I ended up downloading a much better guide from the Grundfos web site. 15 Oct 2014
Quality product The last pump we had was noisy and less flexible. Very easy to install and quiet. The pump has a number of options that help to vary the flow depending on the time of year. The product was expensive compared to others but the has proved to be very reliable. 14 Jul 2014
