Bolted right in, no spacers, no trouble
I replaced an older pump for my in home boiler heat system. This is quieter, lighter, and just all around better. The only problem is that it can create a heck of a water hammer when i turn the pump to medium or high. So i don't. Lovely little pump at half the price of a repair or a direct replacement of the old pump. Couldn't be happier.

Excellent, by noisy pump
A little noisy, a little expensive, but great for a multi-story house where the water has to be pumped up and down several times!We live in a "green acres" house and this makes all of the rooms warm now.

Great pump and good price
So far it’s been working fine. It came in all black vs the picture shows red. Don’t care as long as it works for years.

Works
Used this newer version to replace an old squealing Grundfos pump they no longer make. It is definitely noisier than when the old pump was not squealing. I do like that it has three speeds that are easily manually changed between III, II, and I.

Good Purchase
Bought this pump to replace one on our outdoor wood boiler. We got ours through Amazon Warehouse and it came in perfect condition at a great price.

Another bad one! I am done with Grundfos.
This brand new pump would not even turn over. I have a radiant heat system less than 14 years old. This was my 5th Grundfos water circulation pump! There is a lot of end play, but even with a screwdriver you could not turn the rotor. That’s unacceptable le on a brand new motor. I substituted a Taco pump in its place (at half the price) and the system works fine. There is another Grundfos circulator pump for the glycol. It’s smaller, but it has been replaced once as well. The pump I replaced failed sometime in Feb and there were sub zero temperatures so there is damage beyond just a pump replacement as there was no heat in the house. Based on my experience with this brand, I would recommend getting a different brand pump in your system. I really expected top quality for the price. 5 pumps in 14 years is ridiculous.

Straight forward installation
The order and delivery were as expected. It was a simple removal of the old and replacement of new with the water shut on both sides of the pump used in a radiant floor heat system. Read Grundfos instructions. Be sure to let the water back into pump before starting.

Perfect pump
I had undersized 15-52 pump previously. With this pump system is working perfect at medium speed so I can turn up or down if necessary. Pump was shipped quickly. Strong well built pump.
