Grundfos Alpha 2L 15-60
Not the most reliable
My first one of these lasted till just outside of the warranty and then just stopped! Rotor was clear to run and motor and pump showed very little sign of wear. I conclude that the elaborate speed control system must be the reason. On a cold winters day what else could I do - I bought another one from Screwfix - Excellent price and in stock - LIFE SAVERS!
Grundfos however unable to help with spares or repairs - what a waste to throw away a perfectly good pump just because a chip somewhere has failed. Maybe this pump is just too complicated? I am now on the lookout for a hot spare to keep on the self as I have little trust in the new one given that there was absolutely no warning before its predecessors failure.

Central heating pump
Old pump getting noisy & 'pulsing'. New one delivered within a day and fitted in a few minutes.
Runs very quietly and house now warm again.

Very easy to fit and use. So quiet, for the first week had to keep checking it was working. I've already recommended this pump to all my friends and family..

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).
