A patented drop-in gas heat pump water heater that uses half the fuel of a conventional unit.
4 million residential gas water heaters are sold in North America every year. Most operate at a Uniform Energy Factor of just 62–64%. As emissions targets tighten and gas prices climb, water heating is the largest untapped efficiency opportunity in residential heating. The transition is also driven by the societal push toward decarbonization and lower CO₂ emissions.
Replace existing water heaters with a high-efficiency solution that requires no gas or electricity upgrades, reduces energy costs and emissions, and delivers the same dependable comfort you've always enjoyed.
The unique proprietary low-complexity architecture enables a compact, robust and cost-efficient design that supports scalable manufacturing and broad residential adoption. The technology delivers high-efficiency water heating in a drop-in format, fitting within the footprint of a conventional gas-fired storage water heater and requiring no gas or electrical infrastructure upgrades.
The thermochemical heat pump is hermetically sealed and uses a natural refrigerant with zero ozone depletion potential (ODP) and zero global warming potential (GWP). The system is designed to deliver robust long-term performance whilst minimizing environmental impact.
By producing the same amount of hot water with substantially less gas, HeatAmp can reduce water-heating energy consumption by up to 50%, helping households lower their utility bills without sacrificing comfort or performance.
We lead development of drop-in replacement gas-driven heat pump water heaters.
4 million gas water heaters are replaced annually in North America. Today, high-efficiency models represent only ~5% of the market, but tightening regulations are expected to drive that share toward 40%. HeatAmp is positioned to claim the cost-effective end of that growth.
Gas water heating is a global challenge, with Europe and fast-growing markets like China and India being key areas of interest. Opportunities in these regions depend on suitable manufacturing partners.
The base technology has potential for other applications and markets — it can be seen as a scalable, adaptable platform that extends well beyond residential water heating.
The HeatAmp water heater combines a high-efficiency gas burner with a novel thermochemical heat pump to produce hot water using significantly less gas than conventional water heaters.
The figure illustrates the principle of a thermochemical process.
The majority of conventional gas water heaters typically achieve efficiencies around 60%. By combining gas combustion with ambient heat recovery, the HeatAmp system can achieve gas efficiencies of 120–125%. This means more hot water from every unit of gas consumed, reducing both heating costs and environmental impact.
The scalable, low-complexity heat pump architecture enables significant reductions in size and cost, making it well-suited for large-scale manufacturing and residential deployment.
Built from the ground up over the past eight years in collaboration with leading industry partners — progressing from early breadboard systems to fully engineered prototypes designed for scalable manufacturing.
Each development stage has validated performance and reliability. The next milestone is prototyping for industrialization and field testing.
Over $1.4M in non-dilutive support from partner utilities and the US Department of Energy.
