Williamson-thermoflo Gsa-100 - 62k Btu - 82.9% Afue - Steam Gas Boiler - Chimney Vent Review Sep 14, 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.

I bought this unit not knowing if it would heat my 19 x 21 kitchen, but to my surprise I have not had to turn the unit any higher than 4 and that was on a -20 day . So my wife is well pleased with me.

Replaced a 22 year old Triangle tube heater with the Smart 40. My furnace hardly ever runs to keep my hot water hot unless I am using it. Really holds the heat. I have had it installed about a month now and I think it was a great purchase. A little expensive, but if it last as long as my last one, I'll be happy.
