The Thermoflo GWS 95,000 BTU 84.6% efficient Gas Fired Boiler is a Energy Savings USA choice for high efficiency, low price gas boiler. We like it because of its simplicity of design ( no problematic injection pump) and installation and Lifetime warranty against leaking. Most importantly is its high effiency, reliabity, and low water content of 2.1 gallons (which means low heat loss and high recovery). This is a cast iron boiler with circulator and draft inducer. This boiler will handle about 160 linear feet of hot water baseword based on 500 btu per linear foot. If purchasing you may pick gas type at the shopping cart page (natural or propane) To see more information on this boiler check out there web site at http://www.williamson-thermoflo.com
