WATERSTAGE™ ATW Systems What is the difference between an air conditioner and an ATW system?
An ATW system takes heat energy from the surrounding air and transfers it to water in an enclosed tank; it is used mainly for heating purposes. An air conditioner removes heat from the indoor air and transfers it outside in summer, and collects heat from the outside air and transfers it inside your house in winter. An air conditioner is used for both heating and cooling applications.
