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 […]
SMTI’s first commercial water heating field test was commissioned in North East Tennessee in April, 2018. A 140,000 btu/hr gas absorption heat pump prototype was installed at a commercial laundry facility where it will provide base load water heating over the next year. For ease of installation, the GAHP and a pair of 100 gallon […]
SMTI’s second residential “combi” field test was commissioned in Wisconsin in February. A Beta model GAHP, nominal 80,000 btu/hr, was installed at a home where it will provide space and water heating through the 2018/2019 heating season. The installation includes an SMTI designed hydronic-to-air indoor coil, a fully modulating air handler and an 80 gallon […]
SMTI’s advanced gas heating technology featured in October edition of AGA’s American Gas Magazine.
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 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 […]
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 […]
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 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 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 […]
