Solahart Atmos® Heat Pumps create hot water out of thin air. They’re the smart choice for people looking for an energy efficient alternative to an electric water heater but who are unable to install a solar water heater. Solahart Atmos Heat Pumps work by drawing heat from the surrounding air and is a reliable and efficient way to reduce energy consumption, and cut greenhouse gas emissions. Heat from the air is absorbed by an evaporator and transferred to the water through an advanced wrap-around microchannel heat exchange technology for uniform and faster water heating. This process continues while heating is required until the water in the tank reaches the hot water temperature set-point. Atmos Heat Pumps work all year round, day or night, in sunshine or rain and even on cooler days, as there is always heat in the atmosphere which can be used.
