An Energy Star-rated gas furnace or boiler is configured with a Honda generator to create the freewatt micro-combined heat and power (micro-CHP) system. The unit operates when home heating is called for. It generates 1.2 kW of electric power and most of the heat from the generator is recycled to heat the home. Michael Paparone, president and CEO of freewatt producer ECR, (Utica, N.Y, U.S.), said that unit can help reduce a home's carbon footprint by up to 6000 lb/year.
