As we enjoy a delicious dinner at our favorite restaurant, a whole lot of hot water is being used in the back. Excited about the results of our gas-driven heat pump demonstration in the LA where our gas heat pumps reduced gas use by 48% compared to the baseline water heaters, and delivered an additional […]
Great paper by Thomas Manjarres and Allen Dusault of Franklin Energy highlighting the important difference between site energy efficiency and actual carbon emission reduction. Specifically, this paper shows that replacing gas space heating equipment with electric heat pumps in cool climate zones will actually increase carbon emissions, in addition to increasing the home owner’s utility […]
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 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 […]
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
SMTI appears in Accelerate America Magazine – in its April 2019 issue focusing on heat pumps (pg 51). https://issuu.com/shecco/docs/aa1905/44
In March 2019, two of SMTI’s 80,000 BTU/hr Gas Absorption Heat Pump prototypes were commissioned at restaurants in Southern California as demonstration projects. They will provide both DHW heating and supplemental cooling to the full-service restaurants, cutting hot-water heating bills by up to 50%, plus the additional free-cooling benefit. Project economics of 1-3 year paybacks […]
The Canadian government is keen to closely examine SMTI’s gas furnace heat pump technology for use in residential heating, and other applications. Based on analysis and stakeholder feedback developed by Natural Resources Canada (NRCan), the government is nearing a nation-wide mandate for all heating to be done with heat pumps by 2035. SMTI’s technology represents […]
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 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 […]
