Williamson-thermoflo Gsa-150 - 94k Btu - 82.9% Afue - Steam Gas Boiler - Chimney Vent Review Jul 30, 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.

Nothing But The Best Oct 15, 2016

I have 2 of the 30,000 btu units and one 75,000 btu unit. I couldn't be happier with their performance and reliability. I went with these over the competition because of the compact design and the quality that they are built with. The Reznor brand may cost more but I have dealt with other heaters that have failed and caused pipes in the garage to freeze. Now I can leave for days at a time without thinking twice about what's going on back at home in sub zero temps.
