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 Ships Residential Combi Field Test Prototype

In October, 2019 SMTI shipped another Thermally Driven Heat Pump (TDHP) off for a winter field test as part of the latest demo-series.  This prototype along with two others will provide all of the space and water heating for three homes in the Chicago area.  This 80,000 btu/hr (23 kW) natural gas driven air-to-water heat […]

SMTI Field Test Unit installed on Multi-family Building

SMTI is developing a TDHP (Thermally-Driven Heat Pump) product version suitable for multi-family building usage.  SMTI, partnering with a major OEM serving this sector, commissioned a 140,000 BTU output capacity TDHP in September, 2019 to serve both the space-heating and hot water loads of all the units in the building near Chicago.  SMTI’s approach to […]

The Fastest Way to Decarbonize Our Building Heat Loads

A new quantitatively-driven analysis shows that gas absorption heat pumps immediately provide a lower carbon footprint, and ultimately facilitate the way towards faster decarbonization of building heat – faster than electric heat pumps at scale. TDHPs – The Fastest Way to Decarbonize Building Heat
