HEATING APPARATUS, RECREATIONAL VEHICLE WITH HEATING APPARATUS AND METHOD FOR HEATING FLUIDS IN A RECREATIONAL VEHICLE

摘要

A heating apparatus (1), in particular for recreational vehicles like campers or caravans, comprises a heating unit (10) and at least one heat exchanging unit (40) coupled to the heating unit (10). The heating unit (10) comprises at least one burner (22) and at least one combustion air fan unit (26). The combustion air fan unit (26) is configured to supply the burner (22) with combustion air. The burner (22) is configured to burn fuel gas or liquid further supplied to the burner (22) together with the combustion air received from the combustion air fan unit (26) to get hot exhaust gasses. The heat exchanging unit (40) is configured to receive the exhaust gasses from the burner (22) and to transfer heat from the exhaust gasses to a fluid to be heated, provided within the heat exchanging unit (40). The burner (22) comprises at least two nozzles( 22b1) and (22b2) configured to supply fuel gas or liquid to a combustion area (22e) in which the fuel gas or liquid is to be burned with the combustion air. Each of the nozzles( 22b1) and (22b2) is coupled to its own fuel gas or liquid valve to control the fuel gas or liquid supply for the nozzles (22b1) and (22b2) independently of each other. Furthermore, the present invention refers to a recreational vehicle with such a heating apparatus (1) and methods for starting and controlling the above heating apparatus (1).
