Boiler-m8 Central Heating Circulating Pump 15-50 15-60 Grundfos + Wilo Gold A Rated Replacement

Pump arrived 3 days after being ordered - Very Good. This is the first of this type of circulation pump that I have purchased. The pump is one week in use. It is very quiet and I have more heat in my radiators with my new pump than with my previous pumps. It is set on auto and functions between 13 and 15 Watts. I read my electricity meter every monday morning and today the reading was 10 units less than previous weeks. That will be a good saving over a year. I can also turn down my radiator thermostats from 3 to 2, and my home is still warm and cosy.

Have installed two pumps now and both very quiet and so much more efficient my one is running at 15 watts down from the old 80+ watt pump and my fathers is running at 35 watts down from 135 watts Both systems have become very quiet all, due to not sucking in air on start up. We have not had to bleed the systems since replacing the pumps. Would recommend and with the 5 year warranty can’t go wrongUpdate. Pump has been running for several months now and it’s fantastic the whole system is so quiet we don’t even know it’s on except that the house is warm, my fathers is the same and now they can run the heating all night if they need to with out it waking them up. It’s all brown to the technology I only wish they had invented this pump sooner.

The product arrived promptly. This pump has 3 power setting and an auto, this permits the pump to operate selecting the power needed rather than setting it on 3 the high setting and generating high electric running cost. I have not been able to work out what it is costing to run. It would be helpful if the manufacturer gave power consumption for setting 1, 2 & 3. This pump is pushing water around my bungalow covering 6 radiators and the heat hits them swiftly. Radiators are hot in around 1 minute. It’s predecessor failed in 14 months, Judy outside of its warranty, this pump is supplied with a 3 year extended warranty, although I have not confirmed how to make sure it is activated. Warranty is essential so I plan to get that resolved asap.

The warranty is only available to a qualified installer. That would mean DIY'ers don't get warranty. The pump cavitates in all modes. Producing a white noise while running. Cavitation is said to be very bad for the pump. So, it probably won't last.

I was slightly concerned about this pump as never used 1 from this manufacturer before and it's so much cheaper than the Grundfos equivalent but so far it's been no different. It's super quiet and I'm confident that it's saving money and wear and tear in general. I have an old house with an old system which due to the layout is a bit convoluted but we now don't get woken up in the morning by the pump running

the pump itself seems of a good quality , easy to fit. The connections although simple and tool less are not very well marked just a small set of letters below the connector block , if this pump is fitted in a darkish place deciding which is line and neutral would be quite hard, also the instructions omit them

A good price and the pump arrived within 24 hours of ordering it. A little fiddly to fit, but that was more about where the pump was located. Worked as soon as it was fitted and radiators hot soon after. Perfect.

Arrived on time in good nick. Only just installed it - no problems - working well so far. Assembly is much easier if you stick the rubber seals in place with universal glue some hours before.
