Founded in 2008 by Michael Garrabrant, SMTI evolved from a vision to revolutionize residential and commercial heating solutions. Garrabrant, who previously held key engineering roles at American Water Heater Company and A.O. Smith Water Products Company, recognized the need for more efficient and environmentally friendly heating technologies that didn’t impact the grid.
Over the years, SMTI has focused on developing its flagship product line, the Anesi® brand of gas-fired absorption heat pumps. These innovative systems utilize patented compressor-less technology and operate without harmful refrigerants, achieving an impressive Annual Fuel Utilization Efficiency (AFUE) rating of 140%. This breakthrough technology significantly reduces fuel consumption and carbon emissions, making it an ideal solution for a wide range of heating needs. In 2022, SMTI unveiled its gas absorption heat pump system at the AHR Exposition in Las Vegas. This milestone marked the beginning of SMTI's journey towards commercialization. Anesi products are available in North America through Manufacturing Reps and Distributors.
