Grundfos UPA 15-90N Home Booster Pump 230V 50Hz is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Ace Pump Top marks to Grundfos on this one. Bought a Salamander which was a mistake, flow rate a bit too high for our 4 tap bungalow but the killer was the noise. Sounded like a Chieftain tank starting up. The Grundos is all but silent, and the flow rate boost is perfect. We have only 0.18 bar head. The Salamander boosted extra 1.5 bar, the Grundfos about 0.7. Couple of points to watch out for. Positioning is vertical with flow going up, so in our case called for some creative plumbing involving Robocal auto air vent which I can also recommend. Also the 3/4" threads are not very deep. I plumbed direct to 22mm pipework so couldn't use the 1/2" couplers provided. These use fibre washers but my brass fittings didn't have the correct seating so massive amounts of PTFE tape instead. Slight very slow leak on the outlet terminal, about one drip per hour which will eventually dry up by itself. Despite these drawbacks overall hugely impressed with this great little pump.

Rated 5 out of 5 by from Grundfos Hot Water Pump Great solution to boosting the hot water in the house. Just left it on auto and it works with the flow switch, you would think it is now a combi boiler with the pressure at taps. As long as fitted with Surrey flange at cylinder
