Abstract: A heating device (1) is provided with a sleeve member (14) surrounding a burner element (10) of the heating device, such that a combustion air chamber (15), having a predetermined volume coordinated to the respective configuration of the burner, is obtained between the burner element (10) and the sleeve member (14). The sleeve member (14) may be radially divided into two parts (14a, 14b), which parts are tightened against each other for sealing purposes. At a front end, the combustion air chamber (15) is defined by a cover (16) having an inlet opening (17) for the combustion air, which inlet opening is sealed relative to the environment and is connected with the outlet of a combustion air blower. The sleeve member (14) may be made of a light metal, such as aluminum or an aluminum alloy.
