The Buderus GB142 Wall Hung Residential Gas Boiler is an Ultra Efficient Modulating Condensing Boiler with efficiencies of 94%+ AFUE. This ultra high efficiency makes the Buderus GB142 eligible for the Energy Star, which makes receiving Rebates, Grants, and Tax Credits under a variety of government energy saving incentive programs possible. Buderus started as a manufacturer of cast iron goods in Germany about 1731, and by 1835 they had expanded to five foundries and were well know for their stoves which were known as “Long Burners.” Today they are part of the Bosch Group and have a worldwide presence and in over fifty countries. Today Buderus has product lines including Solar Energy, Geothermal Heat Pumps, Wood Fuel Burners, and Gas and Oil Burners. Their US headquarters is located in Londonderry, N.H. and their main product lines in North America include: hot water boilers, domestic hot water storage tanks, climate and energy controls, panel radiators, and other hot water heating accessories. Buderus is widely recognized as a high-end manufacturer of heating products.
The Buderus GB142 is a Mod/Con Boiler, which is what we in the trades nickname Modulating Condensing Boilers. The modulating condensing feature is what allows these boilers to attain previously unheard of levels of efficiency while lowering emissions to new levels of clean and green that also were previously unattainable. The modulating burner modulates the flame size so it matches the heat load without wasting fuel and the condensing feature uses a second heat exchanger section to scavenge previously unused heat in the flue gases to preheat the water returning to the boiler. This condensing section actually scrubs so much of the heat out of the flue gases that water vapor in the flue gases condense to water and the flue gases are cool enough that they can be exhausted through PVC Pipe. The high efficiencies make the Buderus GB142 eligible for a rebate of up to $200 under the Appliance Stimulus Package, Grants of up to $6500 under the Weatherization Assistance Program if you qualify, and a 30% Tax Credit of up to $1500, along with other Rebates under various state and utility programs in about ½ of the states.
The Buderus GB142 is available in 4 models with modulated outputs ranging from 22,700 to 196,600 BTU/Hr depending on model and application. The GB142/24 has a rated input of 84,800 BTU/Hr, the GB142/30 is 106,000 BTU/Hr, the GB142/45 is 160,900 BTU/Hr, and the GB142/60 is rated at 214,800 BTU/Hr. The Buderus GB142’s have an attractive fully enclosed housing and the boiler features super quiet operation. The GB142 can be fired on natural gas or, LP gas, and has direct vent and sealed vent options. The GB142 has an aluminum heat exchanger and is supplied with a prefabricated manifold that makes installation easy. The GB142 is also supplied with the AM10 outdoor reset control module. The GB142’s are super clean burning with the CO2 content at full load being only 9.2 ppm and NOx emission factor of 22 – 24 ppm depending on the model. The Buderus GB142’s are fully covered a limited warranty for the first year with a limited lifetime warranty on the heat exchanger, which has a pro-rated service charge after 10 years.
The timing is right to consider an upgrade to a more efficient heating system.
