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.

Quality Aug 19, 2016

Have used Runtal UF series before and the quality is excellent. Now if they could sneak more BTUs per foot.

Too Early To Tell Aug 07, 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.
