Williamson-thermoflo Gsa-125 - 78k Btu - 82.9% Afue - Steam Gas Boiler - Chimney Vent Review Sep 13, 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.

Nice Choice Sep 16, 2016

The radiators went together very easily with the connections provided to the heating pex and there were no leaks. very easy to bleed. they provide much more heat than I was getting from my old wall convectors and seem to retain the heat a long time after the boiler is off. Not hard to hang either as long as you separate the hanger prongs in increments of 1/2 inch. Also, my wife was pleasantly surprised by the appearance

Great Heater Dec 16, 2016

Works Great! Aug 26, 2016

January 2016 our heater went out at our business. We ordered the Modine PDP-150,000 BTU Unit Heater. Other than the shipping was slow - we received this heater a little later than expected in Wisconsin. The heater was installed and is working great as of today, March 2.
