ECR said its freewatt home heating system, which it describes as a green alternative in home heating, is now available throughout the state of New York through new partnerships with Irr Supply Centers, North Tonawanda, NY; Security Supply, Selkirk, NY; and John M. Hartel & Co., Montvale, NJ. Using micro-combined heat and power technology, freewatt marries an ENERGY STAR-rated high-efficiency natural gas furnace or boiler to a Honda generator.
