Stone Mountain Technologies, Inc (SMTI) Raised $15M to Commercialize Residential and Commercial GHPs

SMTI, a leading developer of high-efficiency heat pump technologies using natural refrigerants, and Energy Impact Partners (EIP), announced the closing of its Series-A in early November.

The investment, totaling $15 million, enables SMTI to commercialize a new generation of highly energy-efficient heating products, including a gas furnace and water heater replacement for single-family homes, and gas water heater replacement for commercial applications. This initial product offering will be manufactured and marketed in North America under their Anesi™ brand and has the potential to reduce residential and commercial building heating bills and carbon emissions by as much as 50% with no required infrastructure upgrades.

Advanced Hybrid Heat Pump System Installed in Toronto

Enbridge Gas Inc. has installed a first-of-its-kind Advanced Hybrid Heating system, a dual-fuel residential heating and cooling system where a gas heat pump (GHP) is paired with an electric heat pump (EHP) to maximize the benefits of hybrid heating.

In a conventional hybrid heating system, a furnace and an EHP are combined to heat and cool a home. In the Advanced Hybrid Heating System, the gas furnace is replaced with a greater than 120% efficient GHP resulting in the most efficient home heating system available on the market. The GHP also provides domestic hot water for the home.

This new Advanced Hybrid Heating System has been installed in a single-family house in the Greater Toronto Area for field testing. It will provide space heating, cooling, and domestic hot water heating for the household. A smart fuel switch controller will run the system in any of the following modes: GHG (Greenhouse gas) reduction mode, utility cost-saving mode, and comfort mode. The performance of the system will be monitored for one year to quantify energy saving, greenhouse gas reduction, and occupant comfort. Test results will be available in Q4, 2023.
