Harvest Thermal

Harvest Thermal is a home energy technology company founded in 2019 that makes the Pod, a smart thermal storage system that replaces or augments conventional water heaters and home heating equipment. The Pod stores thermal energy during cheap overnight electricity hours by heating or chilling a water tank, then uses that stored energy for home heating, cooling, and hot water throughout the day, reducing reliance on expensive peak-time electricity. The system integrates with time-of-use electricity rates and renewable energy programs to automatically optimize when it charges, helping homeowners minimize bills while maximizing consumption of low-carbon electricity. Harvest Thermal targets homes transitioning to heat pumps and all-electric operations, where intelligent thermal storage can dramatically reduce operating costs by avoiding expensive on-peak electricity. The company raised $18M and is working with utility partners to deploy the Pod as a grid-interactive asset that utilities can manage to reduce peak demand. Harvest Thermal represents an accessible and cost-effective path to home energy storage that complements or replaces electrochemical battery systems.
