Abstract
A device, system and method for heating fluid (air) in a flue to create a draw prior to combusting a fuel in a combustion device. The device, system and method includes a housing that may be integrated about the flue. The housing may include a heat exchanger that itself may include a heating source that may be in thermal communication with the flue and a temperature differentiation driver. The heat exchanger may operate to transfer heat energy from the heating source to a fluid constrained to a path created by the flue. The result is a pressure differential created within the flue to help draw the fluid out of the combustion device. The heat exchanger may be configured such that it may cause heat transfer to the heavier, more dense fluid contained within the ventilation system prior to combusting fuel in a combustion device, thereby causing the fluid to be relatively less dense thus creating a draw.
