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.
