Great Product Aug 18, 2016

The product arrived in less than 2-weeks. The unit is a high quality boiler made in Minnesota. This one was for my personal home. If you need questions answered or tech service, they are top notch. They know their product. This unit has been in operation for about a month and works flawlessly. I also have one of their plenum heaters, in use now for 12 years, without any problems what-so-ever.

This unit is replacing a 66 year old unit my old unit was only @ 33to34% this one is @ 82% and it is working great I love it and it will save on my heating cost also. Thanks for the speedy delivery too.

Williamson-thermoflo Gsa-200 - 125k Btu - 82.8% Afue - Steam Gas Boiler - Chimney Vent Review Sep 12, 2016

Built by a division of Weil McLain the boiler it is similar to their products. Seems to be build well and I hope to have years of trouble free working status. A little difficult to install given the position of the ports. I will recommend this product to others.

So Far, So Good. Sep 10, 2016

Installed for 1 week. Very quiet and responsive. Nice to wake up to an inviting temperature instead of cold.
