Even informed buyers must find the landscape very confusing. One might think that a government website could help solve the confusion. However, even the EPA site listing approved […]
A cord of freshly cut hardwood from a northern forest (green firewood) contains about 24,000,000 British Thermal Units (Btus) and weighs about 4,500 pounds. After proper air drying, the same cord weighs only 3,500 pounds. The loss of 1,000 pounds of water at 8.34 pounds per gallon is about 120 gallons. The next time you […]
Climate change and environmental concerns drive many of today’s consumer decisions. One of the biggest environmental decisions homeowners can make is how to heat. Tucked away in basements and utility rooms, boilers and furnaces are quietly emitting about 75% of household carbon dioxide emissions. Making large reductions in household carbon footprints, therefore, requires de-fossilizing home […]
As of December 2020, installations of wood-fueled boilers and stoves for home heating with an efficiency of 75% or better qualify for a 26% federal tax credit. The Investment Tax Credit or ITC, which has been available for other renewable energy installations for years, was finally granted for efficient wood heating after almost a decade […]

Green wood chip boilers and fuel handling systems require more infrastructure, which means both a larger investment and larger requirements for floor space. Green wood chips do not require as much processing and handling […]
