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 Commissions ‘Heat Pump Furnace’ Field Test Prototypes

SMTI and its commercialization partners successfully commissioned an 80,000 BTU/hr gas heat pump furnace prototype on two single family residential homes in Wisconsin.  These 3rd generation units will provide all of the heat required by these homes (including hot water in one home) without need for backup, even in that region’s decidedly cold winters.  SMTI’s […]

SMTI develops first wall-hung gas-fueled heat pump boiler/furnace for low load buildings

SMTI completed its first prototype thermally-driven heat pump (TDHP) with a 20,000 BTU/hr (6 kW)  capacity.  Filling out SMTI’s suite of existing prototypes (ranging from 10-140 kBTU/hr), the 6 kW model is well-sized to provide both space and water heating for low-load and net-zero energy homes, as well as individual units in multi-family buildings. This […]

5th Generation Residential Gas Heat Pump Water Heaters Begin Field Test

Six 5th generation prototype gas heat pump water heaters were recently commissioned.  Five were installed in homes in Southern California while the sixth was sent to a test lab for further evaluation. The units were installed in June of 2018 and will continue operation for 1 year. Prior to installation, one of the prototypes was […]
