Intellihot, Chicago, Illinois, introduces its newly released family of Electro tankless heat pump water heaters. The electric heat pump water heater utilizes carbon dioxide as its refrigerant and is paired with a specially designed battery.
It absorbs heat from the external air, then this energy is stored in the thermal battery; that way, when there is demand, cold water flows through a heat exchanger located inside the thermal battery and the water is heated to the required temperature. It features a COP of 4.9.
