Grundfos99199622 Pump, Black

Easy to fit and very quiet in operation. My original was a Grundfos which lasted for 25 years.and was in use every day for hot water and daily in winter for central heating too.

Got this to replace a 7 year old Grundfos Alpha 2L 15-150 130 pump that had become noisy. I believe that the Alpha 2L was an early attempt by Grundfos to make an energy efficient central heating pump and in fact I was lucky to get the life out of it that I did. This pump is completely silent and was an easy replacement as it fitted in the original space and the control unit can be orientated in multiple ways to suit your particular need. Very good.

Does the job for my system.... Don't attempt unless you have the skills...

Very quiet, with 3 fixed speeds and other variable speed settings. The only criticism is that the instructions don’t give enough guidance as to which setting to use (e.g. constant speed or constant pressure).

Replacing my old 12yr old Selectric pump. Straight swap and all done in 30 minutes. Much quieter than the old pump and more efficient.

Broke after 3 months.Unable to get replacement unless postage paid for return and replacement.Bad experience.

fitted really well and slightly smaller than our old one which in my case is good.

A Good price and quick delivery, fitted the pump works really well and so quiet
