I would buy this product again,
This product plumbed right into the location of the old boiler. It has worked very well for two weeks, and there have been no problems. The iron castings caused a few installation problems, the male NPT threaded portions actually bottomed out in the female portions. This is not a good thing, however with some effort they were sealed.

Working well
Shipping is fast. Well packed. No damage.
Installed and working well so far.
Got a defective gasket for the pump. Leaked after 2 days. I have to order a new one.
Great price. I rated it 4 stars because I was told warranty is void because I am using it in Canada.
