Abstract
A heater (independent vehicle heater) which can be operated in a particularly wide range between full load and partial load, e.g., 1:10 to 1:15, is shown. This is achieved by the annular space surrounding the combustion chamber being divided into two partial compartments and by supplying the combustion air to these partial compartments. A control element (back-pressure-controlled control element), which separates some of the air passage openings between the annular space and the combustion chamber from the passage of air, is arranged in the combustion air line.
