This pump is used in a two zone wood and gas fired boiler system for infloor heating and radiators on the second floor. The pumps I ordered were less than half the cost of purchasing this pump in Canada, including shipping. They are a must have in my system so I need to keep two spares on hand. I live 2 hours away from a major centre and it's nice to know I can afford to have two of these pumps on hand. Easy installation for anyone with even a little bit of handyman genes.

It was defective
I have several Grundfos pumps. Some are still working after 18 years. This one did not work out of the box. I did purchase a Grundfos pump locally and it is functioning fine.

Boiler pump took care of the problem
from Christopher, IL
I can't believe how quiet this pump is compared to my old boiler pump. I have ZERO complaints! Easy to install and get working!
from Wellston, OK
I built my house in 1978 and have used these pumps to recirculate water through a fireplace jacket that heats a 2000 sq. ft. home with no problem. The first pump lasted over 17 years, I'm on the second one now and I bought this new one recently, thinking that it might be time for some problems, but so far the second one is still working fine. Who knows, I may never need the new one!
