Stone Mountain Technologies

Based in Johnson City, Tennessee, SMTI has been developing and perfecting a cost-effective and scalable design for Thermally-Driven Heat Pumps since 2009. The approach re-configures an age-old thermodynamic cycle into high-efficiency replacement products for furnaces, boilers, and hot-water heaters in homes and light commercial buildings. The company is commercializing several HVAC products with OEM partners, and also significant support from utilities and other energy efficiency stakeholders. SMTI's approach offers the most economically practical method to decarbonize building heat loads on a large scale, a major source of green-house gases and other pollutants.
