Gas Heating Device

Abstract

A gas heating device comprising a gas burner, a combustion chamber for the flames of the gas burner and a convection air conduit with an air inlet and an air outlet for evacuating a convection air stream that has been heated in the gas heating device. The aim of the invention is to enable the gas heating device to be used for various purposes. To achieve this, the combustion chamber of the gas burner and the convection air conduit are connected to allow the passage of fluid. An exhaust gas stream can thus mix with the convection air stream.
