A reliable motor home heater is worth its weight in gold. It ensures a comfortable, cosy home on four wheels wherever you go. Whether you’re travelling in the cold season or high in the mountains, a good heater keeps you self-sufficient so you can enjoy boundless autarkic adventures.

What is important when choosing a heating system?

Most motor homes come with a Truma heater as standard. However, it’s worth taking a closer look at the different heating systems – both when converting a motor home yourself and before purchasing one.  This will ensure that you have the right heater on board when temperatures drop.  Find out which variant best suits your needs and your vehicle here.

Why choose an air heater from Truma?

Unlike hot water heaters, which operate via a complex system of water lines and heating elements, our air heaters warm the interior air up directly. This makes them significantly lighter, more compact and quicker to install. Above all, they heat up the vehicle faster – ideal for spontaneous trips and limited motor home space.

Our air heaters impress with numerous advantages:

  • Quick heat distribution: Air heaters warm up indoor air directly – for pleasantly warm temperatures in the shortest possible time.
  • Energy efficiency and low consumption: Modern air heaters are efficient in both fuel and electricity consumption.
  • Compact design and easy installation: No complex water lines like those in hot water heaters. Air heaters are lighter and more compact – ideal for limited space in motor homes.

Truma offers three types of air heater: gas, diesel and electric heaters. Flexible, autarkic travel is very important to us at Truma. That’s why most of our gas and diesel heaters are also available as so-called ‘E-variants’ with a Heat Hybrid function, giving you the option of heating purely with electrical power or in hybrid mode instead of using fuel.

Discover the heater types:

Gas heaters – proven engineering for campers

Gas heaters have been the first choice for many caravan and motor home owners for years. Truma gas heaters impress with their reliability and particularly low noise levels. They are also ideal for pitches without electricity connections.

Truma offers three different product families for gas heaters: the robust S heaters, which are particularly popular for installation in caravans; the Truma VarioHeat model series, which is ideal for panel vans as they are particularly compact and flexible to install; and our Combi heaters in the Combi and CombiNeo series. These can warm up rooms and hot water in a single device.

All variants feature permanently installed warm air ducts that distribute heat evenly throughout the interior, ensuring pleasant temperatures throughout.

Your advantages with a Truma gas heater:

✔ Large variety of models for every vehicle type

✔ Reliable and low-maintenance

✔ Quiet and odourless operation

Diesel heaters – for maximum range and independence

When choosing a diesel heater, your personal travel habits are especially important to consider.  If you frequently camp off-grid, travel to remote regions, or want to stay independent of gas cylinders, a diesel heater is ideal. Truma diesel heaters use fuel directly from the vehicle tank, enabling convenient, reliable heating without a gas cylinder. Their low power consumption and large tank capacity makes them ideal for winter camping, long journeys, and tours through countries with poor gas infrastructure. At Truma, diesel heaters are only available as Combi heaters.

Advantages of Truma diesel heaters:

✔ Diesel is available almost everywhere – maximum independence

✔ Convenient: refuel, move off, heat up

✔ Particularly suitable for winter camping and long-distance journeys

Electric heaters – comfort and efficiency with shore power

Electric heaters – comfort and efficiency with shore power

Truma electric heaters are perfect for compact vehicles or as additional heaters in fossil fuel heating systems. Extremely practical: On campsites with all-inclusive electricity, you can reduce costs and increase heating power at the same time.

Benefits:

✔ Intuitive to use and maintenance-free

✔ Saves gas/diesel as additional heater

Whether gas, diesel or electric – Truma has the right solution for every requirement. Gas scores points with its proven technology and quiet operation, diesel offers maximum range and low operating costs, and electricity gives you flexibility and ease of use.
