SMTI Wins DOE Grant
SMTI Wins DOE Grant to Commercialize Its Residential Furnace ProductSMTI is pleased to announce that it has been selected as an awardee by the US Department of Energy’s Building Technology Office for a $2.7 million grant to accelerate commercialization of a residential heat pump warm-air furnace replacement product. This innovative grant, a new approach for […]
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 partnership […]
SMTI Delivers Beta 80,000 Btu/hr GAHP Prototype to GTI
SMTI delivered a 2nd generation “Beta” prototype to Gas Technology Institute for 3rd party testing. GTI will conduct both steady-state and simulated “real-world” tests at a variety of outside air and delivered water temperatures. The Beta series prototypes incorporate several design improvements from original “Alpha” series prototypes developed and tested under a DOE grant. UPDATE: […]
SMTI Demonstrates Prototype Chiller for US Army & Navy
SMTI hosted representatives from the US Army and Navy to demonstrate our 2RT absorption chiller prototype. The trailer-mounted chiller/engine-generator package, produced 2RT of cooling using the waste heat (exhaust) of the engine. The absorption chiller replaced the electric air conditioner that is normally installed on the trailer, which requires more than half of the electrical […]
First 80,000 Btu/hr GAHP Prototype Field Test Unit Installed
SMTI’s very first 80,000 Btu/hr GAHP prototype (Alpha 1) was installed as a field test unit, in a warehouse heating application. The original proof-of-concept prototype, developed under a DOE grant, is hydronically connected to two ceiling-mounted fan-coils. Each fan-coil is controlled with its own programmable thermostat, creating two distinct heating zones. The 4:1 modulating GAHP […]
SMTI Wins Outstanding Venture Award at NREL Industry Growth Forum
In a competition with 30 other new ventures presenting at National Renewable Energy Laboratory’s 28th annual clean technologies investor event, Stone Mountain walked away with an Outstanding Venture Award. A panel of judges from amongst the financial community / investor attendees rated each presentation across four criteria. SMTI was one of three winners out of […]
SMTI Installs Four GHPWH Field Test Units in Pacific Northwest
SMTI commissioned four 3rd generation gas heat pump water heater prototypes in the Pacific Northwest, the first major field test of this exciting new water heating technology. In partnership with the Gas Technology Institute (GTI), who is providing overall project management and M&V, and the Northwest Energy Efficiency Association (NEEA), these ultra-high efficiency units replaced […]
