Abstract: A heating apparatus, in particular for recreational vehicles like campers or caravans, comprises a heating unit and at least one heat exchanging unit coupled to the heating unit. The heating unit comprises at least one burner and at least one combustion air fan unit. The combustion air fan unit is configured to supply the burner with combustion air. The burneris configured to burn fuel gas or liquid further supplied to the burnertogether with the combustion air received from the combustion air fan unitto get hot exhaust gasses. The heat exchanging unitis configured to receive the exhaust gasses from the burnerand to transfer heat from the exhaust gasses to a fluid to be heated, provided within the heat exchanging unit. The burnercomprises at least two nozzles configured to supply fuel gas or liquid to a combustion area in which the fuel gas or liquid is to be burned with the combustion air.

Abstract: A heating apparatus, in particular for recreational vehicles like campers or caravans, comprises a heating unit and two separate heat exchanging units, which are coupled to the heating unit in parallel with each other. The heating unit comprises one burner for each heat exchanging unit, and at least one combustion air fan unit configured to supply the burners with combustion air. The burners are configured to burn fuel gas or liquid further supplied to each of the burners together with the combustion air received from the combustion air fan unit to get hot exhaust gasses. The heat exchanging units and are configured to receive the exhaust gasses from the burners, and to transfer heat from the exhaust gasses to fluids to be heated, provided within the heat exchanging units. The heat exchanging units are positioned in parallel with each other side by side on one side of the heating unit. Furthermore, the present invention refers to a recreational vehicle with such a heating apparatus.

Abstract: A heating apparatus, in particular for recreational vehicles like campers or caravans, comprises a heating unit and two separate heat exchanging units, which are coupled to the heating unit in parallel with each other. The heating unit comprises one burner for each heat exchanging unit and one common single combustion air fan unit. The single combustion air fan unit is configured to supply both burners with combustion air, and the burners are configured to burn fuel gas or liquid further supplied to each of the burners together with the combustion air received from the single combustion air fan unit to get hot exhaust gasses. The heat exchanging units are configured to receive the exhaust gasses from the burners, and to transfer heat from the exhaust gasses to fluids to be heated, provided within the heat exchanging units. Furthermore, the present invention refers to a recreational vehicle with such a heating apparatus and methods for heating two distinct fluids with the above heating apparatus.

Abstract: A heater comprises a combustion chamber and a jacket extending about the combustion chamber. There is a fan having an output which communicates with the combustion chamber to provide combustion air. There is also a fuel delivery system having a variable delivery rate. A burner assembly is connected to the combustion chamber. The burner assembly has a burner mounted thereon adjacent the combustion chamber. The burner receives fuel from the fuel delivery system. There is an exhaust system extending from the combustion chamber. An oxygen sensor is positioned in the exhaust system to detect oxygen content of exhaust gases. There is a control system operatively coupled to the oxygen sensor and the fuel delivery system. The control system controls the delivery rate of the fuel delivery system according to the oxygen content of the exhaust gases.
