The Truma Combi D4E Combination Heater is a versatile and efficient heating solution for small to medium-sized motorhomes and caravans, providing both air heating and hot water in one appliance. As a hybrid system, it includes integrated electric heating elements, allowing users to harness additional electrical power to heat their vehicle. This feature enables the heater to run on 230 V at campsites without drawing power from the vehicle's battery. With the option to operate on diesel, electric, or a combination of both, the Truma Combi D4E offers flexibility to match weather conditions and personal comfort levels. This hybrid approach ensures that no matter the external temperatures, your vehicle remains warm and comfortable.

The Truma Combi D4E Combination Heater stands out for its quick heating ability, ensuring that even in the chill of winter, your living space and water supply can be warmed up rapidly. The unit's 10-litre stainless steel water tank is heated concurrently with the air, eliminating the need for a separate water heater and thereby conserving space and reducing weight. The efficiency of the Combi D4E is evident in its energy usage, which is optimised to reduce consumption while still providing rapid heat up times. With an integrated FrostControl drain valve, the system is also safeguarded against freezing, making it a reliable choice for all-season touring.

Installation flexibility is another significant advantage of the Truma Combi D4E Combination Heater. Its compact design allows for various installation options, accommodating the unique layouts of different vehicles. This compactness does not come at the expense of performance; the Combi D4E is capable of heating both air and water very swiftly, providing immediate comfort upon demand. The presence of four air outlets ensures optimal distribution of warm air throughout the vehicle, creating an even, comfortable temperature in every corner. The integration of a pressure sensor automatically adjusts the combustion air inflow, contributing to the heater's long service life and maintaining efficient combustion control.

Control and operation of the Combi D4E are made user-friendly through the digital Truma CP plus control panel, which is iNet ready, allowing for seamless integration with the Truma iNet X System. This advanced control interface enables users to manage the heating settings conveniently, with the potential for automatic climate control when used in combination with a Truma air conditioner. This level of integration and control makes the Truma Combi D4E an intelligent addition to any vehicle, ensuring that temperature management is both straightforward and efficient, enhancing the overall experience of travel and leisure in the great outdoors.

The Combi D 4 E is structurally identical to the Combi D 4, the only difference being the integrated electric heating elements. The diesel version is equipped with a high-quality burner and therefore reliably heats the vehicle while driving.

At the camp site, simply switch over to electrical mode and run the heater with 230 V, with no need for the vehicle battery. Depending on the required output, choose between diesel, electric or mixed mode: in milder weather, set the appliance to electrical mode, on colder days to diesel mode and in extremely cold weather use mixed mode – diesel and electrical mode. Through four air outlets, the warm air flows into the vehicle where it is distributed optimally.

The powerful Combi D 4 E heats small and medium-sized vehicles within a short time. The appliance also has a 10-litre water tank, which is heated at the same time when hot water is required. This means that you do not need an additional water heater, which saves space and weight. The Combi heater is also very compact and offers many different installation options.

The Combi D 4 E is controlled and monitored with the digital Truma CP plus (iNet ready) control panel or via the iNet X System.
