"Excellent bit of kit. Bought one of these to replace my existing pump on my oil fired boiler. I have been having lots of issues with the boiler overheating since I fitted a underfloor heating kit. Once installed, I set to constant pressure and its been great. All my boiler issues now resolved. Not the cheapest but worth ever penny!!"
"Very good pump from Grundfos to replace my old pump, Not cheap but worth it for the performance, Very quiet when running and all radiators get hot quicker than my old pump could manage even when it was new. I contacted Grundfos Technical before fitting as it is a new type smart pump that can increase and decrease depending on the demand and they said the pump was suitable for my system and suggested the setting to use, Only took 1 hr to fit from start to finish, Great Pump and good advice from Grundfos."
