"Uncover warm possibilities" with Williamson-Thermoflo's GSA gas fired steam boiler. The highly efficient GSA-250-N-IP pumps out 250,000 BTUs with an AFUE (annual fuel utilization efficiency) rating of 83.0 percent. The GSA is also designed with a generous heating surface and an automatic vent damper to maintain that efficiency. This factory-packaged boiler is equipped with many features, such as a spark (intermittent) pilot system, cast-iron sections, and an insulated heavy-gauge steel jacket. The GSA is also easily serviced with all controls in reach and a one-piece access door.
