Grundfos UPS15-58FC circulator pump (Grundfos# 59896341) incorporates a cast iron housing, three speed motor (Low/Med/High) and a built-in, removable check valve. Grundfos UPS15-58FC is among the most popular and most versatile circulator pump models on the market. Pump's performance parameters cover nearly all traditional heating applications - from radiant and baseboards, to fan coils and zoning and many others. 3 speeds allow to set up the circulator pump in a way, that matches the system's requirements, while wet rotor design allows it to be virtually silent while operating.

The radiant heat in my home is provided by hot water circulated by two Grundfos UPS15-58FC pumps, and there can be times when these seem to run for hours on end. When I installed my system, I purposely ordered three of these so that I would have a back-up in the event of an emergency. Well, I am not always the most brilliant person in the world; however, this did prove to be a wise idea. For some reason, one of the first two did fail near the end of the winter. These things can happen. In less than twenty-minutes, I switched out the bad and switched in the good, and the zone was back in business without losing any heat. The next day, I contacted Pex Supply with my warranty information, and a new replacement arrived without issue. Nothing critical has happened since, but I am prepared if it does. Meanwhile, we remain efficiently toasty throughout the cold season here on Cape Cod.

I bought this pump as a spare so I will be evaluating the one I bought in June, 2011. I am using the pump on my home hot water heating system. After installing the pump in June it seemed to work fine. When the heating season started this fall I put the pump on the low setting and it was quite for a few weeks then started to squeak. When I turned it to medium the squeaking stopped so I let it run on medium. In mid December it started to squeak on medium so I turned it to the high setting. It now only squeaks when it starts or stops but does whine(not loud) when running. It still works but at this point I am disappointed. My brother has a pump like mine only it is a single speed and he loves his.

Comments about UPS15-58FC, 3-Speed Circulator Pump, 1/25 HP, 115 volt:
Pump itself is nice. It comes with good quality gaskets and function quietly. The standard flanges are not user friendly as there is not a hex nut end to get a wrench around. Up grade to isolation flanges.
Bottom Line Yes, I would recommend this to a friend

Great product and great company
Needed offset flange
By Rusty the electrician.
from Manchester, NH
I needed a circulator with the flange 90 degrees to the motor housing so this was perfect. I like the three speeds as I can pick one that suits the application. It is easy to wire. Be aware that the housing is threaded for the electrical connector which may have to be installed before mounting this circulator at the boiler manifold. The shipping is very prompt
from Wilmington DE
have a 6ft head, works great for my 800 sqft (4 zone)radiant floor.
would recamend this product to a freind
from Marcelus N Y
I have solar hot water for all my needs. I don't have a hot water heater. I also have radiant heat where I use three of these grundfos pumps. one is for circulating the water through the solar collectors and the other two for circulating water through the radiant heat tubes. These are one of the greatest pumps made.
Perfect as described.

Used this pump in hydronic heating system and fit right in, works perfect.
This is the new standard in circulators
By MM on LI
from Melville, NY
I have three of these on my own system and just installed two on a customers boiler refit. The small size, easy wiring and adjustable flow make these the new standard for hot water heat. From the low setting which is almost silent to the high setting which is barely a hum, these are super quiet. The three settings give a huge flow range with good ratings for head loss, far beyond what a single speed circ will give you. Grundfos has been around for a long time with a good track record. For the same price as similar rated Taco pumps, the multi speed adjustability can't be beat. With a single speed circ, you will always be a little off from the specified flow requirements of your system, either too high or two low. With this little wonder a flick of the switch increases or decreases the flow to better match what you need. Best circulator on the market for residential or light commercial hydronic system
from Zanesville, Ohio
After a lengthy research process, I reluctantly chose this pump to replace my old 100 series B&G. From what I can tell this pump appears to be working better than the series 100 that it replaced. I currently have it set on speed 2 and I can't tell its running with more comfort in the zone in which it controls. I used to hear my old B&G pumping away but now all I hear is the relay kicking on. I plan on replacing my other 3 series 100 with these pumps as soon as possible.
