Air heater systems and control methods

An air heating system for heating air in a room, the air heating system comprising a first air chamber, a first inlet coupling the room to the first air chamber to allow the passage of air from the room into the first air chamber, a first outlet coupling the first air chamber to the room to allow the passage of air from the first air chamber to the room, a first variable speed fan for motivating air to pass from the room to the first air chamber and back into the room, a first inlet temperature sensor which yields a first inlet temperature value, a first outlet temperature sensor which yields a first outlet temperature value, a room temperature sensor which yields a room temperature value, a second air chamber, a second inlet coupling the room to the second air chamber to allow the passage of air from the room into the second air chamber, a second outlet coupling the second air chamber to the room to allow the passage of air from the second air chamber to the room, a second variable speed fan for motivating air to pass from the room to the second air chamber and back into the room, a second inlet temperature sensor which yields a second inlet temperature value, a second outlet temperature sensor which yields a second outlet temperature value, and a controller informationally coupled to each of the first inlet temperature sensor, to pass the first inlet temperature value from the first inlet temperature sensor to the controller, the first outlet temperature sensor, to pass the first outlet temperature value from the first outlet temperature sensor to the controller, the second inlet temperature sensor, to pass the second inlet temperature value from the second inlet temperature sensor to the controller, the second outlet temperature sensor, to pass the second outlet temperature value from the second outlet temperature sensor to the controller, the room temperature sensor to pass the room temperature value from the room temperature sensor to the controller, wherein the controller is adapted to control the speed of the first fan based on at least one of the first inlet temperature value, the first outlet temperature value, and the room temperature value, and to control the speed of the second fan based on at least one of the second inlet temperature value, the second outlet temperature value, and the room temperature value.
