Quality product at a good price!
By Cory S.
Eugene, Oregon
Purchased 08/28/2019 |
Review Posted 09/20/2019
In 1980 I had a solar hot water system installed in our house. After 39 years the original Grundfos pump finally failed.....This pump is the replacement model I needed. After draining the system and removing the old pump, the new one fit in easily and did not require any.plumbing changes. After refilling the system the new pump ran perfectly and the system is back up and running. Another 39 years of service?

A reliable pump
By Allan B
Martinsburg, Pennsylvania
Purchased 11/10/2018 |
Review Posted 12/04/2018
We needed this pump for a 299,00 BTU laundromat boiler. The information provided by eComfort.com allowed us to make sure that this was the right pump. The order arrived very fast -- within just a day or two of placing the order. We would recommend both this pump and eComfort.com

Bullet Proof Product!
By Brad G

Review Posted 09/03/2018
I have been using these pumps in hydronic applications for years. These pumps are bullet proof!
They can be expensive if you buy from a local supply house.

Review Posted 08/23/2018
This pump works great to get hot water into your sinks quickly. It is quiet and has a built in timer. Great value as well, as most of the pumps in this category are $400+

Seems to be a quality pump
By Dennis N.
Camano Island, Washington
Purchased 12/22/2017 |
Review Posted 01/20/2018
The pump has been performing as advertised, and the attached timer seems to be accurate as well. It is a bit noisier in operation than the similar Grundfos pump that this one replaces, however. It could be improved by (1) making it a little quieter in operation, (2) making it easier to mount on a wall (i.e. provide built-in "feet" that could be easily bolted to plywood, studs, etc.), (3) provide pre-soldered 1/2" copper pipe to both inlet and outlet to eliminate the need for soldering altogether, or provide a threaded attachment at either end.

Product Questions
Answered by Ken, the eComfort Product Expert
Can this pump work upside down? That is installed vertically but the flow goes from above to below?

My pump froze. Is there more to changing out the pump than shutting both gate valves and undoing the 4 bolts?
