Gas Hybrid Heat Pump

This study aims to provide additional system performance testing for a prototype dual fuel hybrid heat pump for the residential sector. Developed by a major OEM, this 120 V heat pump is equipped with a gas combustion burner to maximize efficiency and performance. This eliminates the need for expensive 240 V panel upgrades and addresses the size and recovery limitations of 120 V heat pump water heaters. The system is a TRL 8 with prototypes constructed and tested by the OEM which leverages their existing commercially available 120 V electric heat pump water heater form factor. This technology is designed to operate under the electric heat pump system during routine usage, however, during times of peak demand or tank depletion, the natural gas burner will be leveraged.
