Buderus Hot Water Boilers

The residential models -- G234X, GA124, G215, and G124X -- have durable GL-180M high-silicone cast iron construction intended to prevent thermal shock and corrosion and to enhance heat exchange. These models can be converted to burn propane and feature AFUEs of up to 85%.

The commercial models have a higher BTU output. A full 3-pass flue ensures greater heat transfer, and a thermal shock-proof design promotes safety regardless of water temperature.

Buderus G124X boilers are available in natural gas or easily converted to propane. Efficiency ratings of 84.3%. High efficiency atmospheric gas boiler. Available in a variety of sizes ranging from 53,000 BTU/Hr to 96,000 BTU/Hr. This is old reliable. Non-condensing. It is an atmospheric design which draws the air it needs from the surrounding space. It is an open burner design. It must vent to a vertial chimney. It is quiet (though not silent). It is a good choice in a traditional cast iron residential boiler replacement. It has modern efficiency engineered into it however and has Honeywell controls (which we like). We have installed many of these over the years here in Seattle.Color brochure GXseries boilers available

Buderus GA124 boilers are designed for single or multiple famliy homes and guarantee reliable heating for many years. Sealed combustion and draft induced venting design. Very quiet running (virtually silent to my experience). Direct vent uses air from outside and side vents combustion gases. Efficiency ratings of 85%+ . Very popular for use in finished basements where silent operation is desirable. Very reliable. Solid sate controller. Color brochure GA series boiler available
