How do heat recovery systems work | The Renewable Energy Hub recovery systems work by drawing on that potentially valuable warm air or water in a property and getting it to work just a little bit harder for us. In a world without a green technology like heat recovery, air circulates around an office, becomes stale and is replaced by colder air that it is warmed up by the ventilation system.
