First, what do we expect by a “hybrid” water heater? It’s an electronic water heater that blends a heat pump method with a storage-tank water heater. Fairly than using electrical resistance to boil the water in the tub (i.e. driving energy by heating components to apply them hot), the water heater draws heat from the ambient air around the water heater using the heat pump. The refrigerant in the energy pump that employed the extreme heat transports it to a heat exchanger that then releases it into the vessel to increase the water temperature.
