Our Vision

Vision Statement

The heat pump “revolution” has already begun (growing globally at 8.5% per year). It promises dramatic savings for heating appliance operating costs through major leaps in energy efficiency, using climate friendly methods to promote human comfort.

However, electrically-driven heat pumps (the most common so far) have limitations. They cannot match the comfort and economy of conventional furnaces and boilers in cooler climates. Thermally-driven heat pumps (using natural gas, propane, fuel oil, bio-fuels, and even the sun) – provide the energy and climate benefits of heat pumps without sacrificing comfort or convenience – and are now poised to join the revolution.

Over the next decade, thermally-driven heat pumps will replace furnaces, boilers and gas water heaters as the dominant method of supplying the world’s heating needs.

Are you ready to join the revolution?


SMTI has developed cost efffective and scalable component designs that enable sorption heat pumps to compete against “standard” direct-fired heating systems.
Sorption heat pumps are powered by a heat source – natural gas, waste heat, even solar. Sorption heat pumps can provide heating, cooling or refrigeration. Sorption heat pumps use natural refrigerants with Zero GWP and are cost effective for gas-fired heating and heat/solar-fired cooling/refrigeration.

SMTI Hits 1.41 COP Target With Commercial Sized GAHP

SMTI recently achieved a 1.41 COP (coefficient of performance) at design conditions for our “Beta” 140,000 Btu/hr GAHP model. The commercial-sized (for water and space heating) prototype was developed by SMTI in cooperation with Oak Ridge National Lab and an OEM partner. Testing at ORNL in October was below original target (COP of 1.35), which […]

4th Generation Residential Gas Heat Pump Water Heater Field Test Installed

SMTI is proud to announce that a 4th generation GHPWH prototype was installed in a home in Birmingham, Alabama (serving a family of four). SMTI, with an OEM partner for the storage tank, fabricated and tested the prototype prior to installation. Gas Technology Institute is providing M&V (including baseline) and overall project management. The new […]

Residential “Combi” Field Test Site Upgraded to Beta Model

SMTI’s first residential “combi” field test installation in Erwin, TN was upgraded to a Beta model, nominal 80,000 Btu/hr GAHP. Originally installed in March using an early Alpha prototype, the GAHP provides all of the space and water heating for the home, replacing a standard gas furnace and electric storage water heater. The project, in […]
