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.

Heating device, particularly vehicle heating device

A motor vehicle heating system which is provided in a motor vehicle coolant circuit containing a motor vehicle engine, a motor vehicle heater with a heat exchanger and an associated blower, and a fuel operated heating device that is independent of the motor vehicle engine and is connected upstream from the motor vehicle heater, and a process for operating such a motor vehicle heating system, by which the motor vehicle engine in the motor vehicle coolant circuit is heated first to a temperature which is low yet facilitates its starting, and then the coolant is heated so that the motor vehicle heater can provide heat quickly. Until a first predetermined temperature of the coolant is reached, the coolant, is circulated in the complete motor vehicle coolant circuit. Then, the coolant, while bypassing the motor vehicle engine and the motor vehicle heater, is circulated between the intake and the outlet of the fuel operated heating device, until a second predetermined temperature is reached, at which point, the bypass connecting the intake and outlet of the heating device is opened. After reaching and exceeding the second predetermined temperature, the coolant is the, again, gradually circulated in a controlled manner in the complete motor vehicle coolant circuit as the bypass is gradually closed until its final closed position.
