Rated 5 out of 5 by from Excellent product Excellent product as per from Grunfos very powerful pump

Rated 5 out of 5 by from Is it working? Yes it is! Bought to replace a noisy Wilo Gold RS60. This was a direct replacement and is practically silent. Had to double check that it was actually working the difference between the two was so vast.

Rated 4 out of 5 by from oh dear fitted it the wrong way round, leaked everywhere when i took it off as i forgot to drain back down, instructions are useless as i cant read.

Rated 5 out of 5 by from A good start Bought to replace a brand new Grundfos UPS2 (which didn't start properly - just pulsed, as reported by others). This has had no such troubles, seems capable of pumping very hard if needed, is about as close to silent as you can get ... Only mid-rating for reliability as I haven't had it installed for long so can't say good or bad (seems fine so far though). Tip - always bleed radiators in ascending order (downstairs first then upstairs) with the pump not running.

Would this work as a replacement for my UPS 25-60 130?

Asked by: Darb595

Do I need to fit an external pipe thermostat to control the pump?

I've been advised that I will also need a pipe thermostat which will be wired into the pump to control when it comes on. Is that right? If so, any suggestions on a suitable unit?
Asked by: CHNewbie

Powerful enough for 22 rads in 3000sq ft house?

We currently have a Grundfos 15-50/130 pump, but around 6 of our 22 rads don't get hot. All rads are new with TRVs and the system was balanced recently. Our 46kw boiler is also newish. Should we replace the pump? If so, would this one be suitable?
Asked by: JulT

Does the pump still allow water to flow through it (eg by gravity) when it is not running?

Asked by: Katherine
No. A gravity system is not pumped, if your asking in a power cut would say a wood burning stove or Rayburn build up heat and be a risk if a pump was fitted on the primary.... Yes it would be a risk. Hope that helps
