Williamson-thermoflo Gsa-250 - 157k Btu - 83.0% Afue - Steam Gas Boiler - Chimney Vent Review Aug 06, 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.

Very Pleased Oct 13, 2016

Ordered late Friday, and it arrived on Thursday in good shape. I will order here again.

Nothing But The Best Sep 12, 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.

Cold Air Rocks Oct 28, 2016

Received unit only issue unit would be left in driveway not placed on porch. Family strained and put unit inside house. My only complaint. Unit working great. Cold Air Rocks. It has been a sweat box. Good product and great price. I strongly recommend a/c unit.

Too Early To Tell Aug 12, 2016

Hooked up the heater in late June, so no way to tell how it will work when the cold weather arrives. Hook up was easy, except the schematic didn't really tell which of the possible 5-6 spots the two line thermostat was to be hooked. Blew a fuse the first time I turned it on, but the second placing of the thermostat lines worked.
