Truma Combi 4

Combined Heater and Boiler for Caravans

This device combines interior heating and water heating into one compact solution. It operates on gas and efficiently distributes heat throughout the living space via a warm air distribution system. A variant with electric auxiliary heating at 230V is also available, offering higher performance and more flexible operation.

Control is provided by a modern panel, allowing you to manage the entire system, including the option to connect to a mobile application.

Heat is distributed via air ducts running through the vehicle – these components are always addressed individually according to the specific installation and are not included in the basic package.
