Gas cylinders have the annoying habit of becoming empty in the middle of the night. You can put a stop to this with the Truma DuoControl CS which automatically switches from the empty operating cylinder to the reserve.
The Truma dual-cylinder gas pressure regulator automatically switches to the reserve cylinder. The integrated crash sensor allows you to operate the gas system safely even when on the road.
With an air conditioning system from Truma you can always have exactly the temperature you want inside your vehicle. It is not only the cooling output that counts, there is another function of the air conditioning system that is equally as important: it can dehumidify the air reliably. The higher the room temperature, the lower the humidity should be, because the body can discharge excess heat much more easily when the room air is dry. A high level of humidity often feels oppressive. The temperature and humidity level are perfectly aligned in all air conditioning systems from Truma.
Even if the weather is tropical outside, you should only cool down your motorhome or caravanmoderately. Experts recommend only cooling the temperature by around six degrees. This even applies when it is 35°C in the shade. If the temperature difference between the inside and the outside is too large, then this can lead to circulatory problems and illness.

Want to turn on the Truma Combi heater whilst you are still on the ski slope so you can return to a warm vehicle? The Truma iNet System makes it possible. You can even (remote) control Truma air conditioning systems via a smartphone or tablet – for instance, when you are on the beach or out hiking. The new Truma air conditioning control ensures a constant temperature in the motorhome and coordinates the heater and air conditioning systems perfectly.
The heart of this system is the Truma iNet Box. It is the central control unit of the system and enables communication between the Truma App and the Truma devices. When near the vehicle, all commands can be issued completely free of charge via Bluetooth, and if you are further away by means of SMS. Continue reading
There is no way of knowing what the weather will be like. Not even in Italy. Being able to control your air conditioning system means you can cope whatever the temperature. The Truma iNet Box acts as a central control unit linked to the networked Truma devices.
It forms the interface to the Truma Combi and the air conditioning systems, and also enables the devices to communicate with each other. The new air conditioning control function controls the system via the Truma App. The digital control panel CP plus – iNet ready coordinates the Truma air conditioning system and the Combi heater perfectly.

A reliable power supply is imperative if you want to make sure manoeuvring your caravan with the Truma Mover® is possible at any time. In conjunction with the Mover® PowerSet, the Truma SolarSet 23 protects the battery of the Truma Mover® against deep discharging. The set also maintains the voltage in the battery, even when it is overcast outside.
Truma Solarset
It is important to keep the battery of the Truma Mover® PowerSet fully charged because the SolarSet23 is only suitable for maintaining the charging level. The Truma BC10 charger is ideal for gentle charging.
Deep discharging and its consequences
The battery has deep discharged, if the battery voltage drops below 10.8 Volt, i.e. more capacity has been drawn from the battery than allowed. The battery capacity should not drop below 70 percent; this ensures a long service life that is measured in charging cycles.
The following factors can lead to deep discharging: Continue reading
An obligation for mud flaps on Caravans, based on EU-Regulation 109/2011, prescribes -among others-that mud flaps must be existent behind the tires of a caravan. Continue reading
The digital control unit
can not only be used for our heater type Combi 4 or Combi 6 (gas/electro- or dieselversion), but is also compatible with our air-conditioning system Saphir Compact and Comfort RC.
It must be notified, that the air-conditioning System Saphir Compact can only be operated with the digital control unit with serial-number 23091001 or higher. Otherwise the electronik must be changed in adition.
Replacement of the heat exchanger is not necessary for Truma liquid gas heaters
Worried customers frequently ask us about the regulation that stipulates that heat exchangers in vehicle heaters need to be replaced after 10 years.
Here is our detailed explanation: (This can also be submitted to the TÜV/Dekra if they do not have a copy.)
In compliance with the Road Traffic Regulations “Technical requirements for vehicle parts for the type test in compliance with §22a StVZO” dated 05.07.1973 for heaters operated with liquid fuels (diesel, petrol), the heat exchanger must be replaced after 10 years of use.
The reason for this are combustion residues.
In the new version of these “Technical requirements” dated 19.03.1990 the Federal Motor Vehicle and Transport Authority also demands the replacement of the heat exchanger in heaters operated with gaseous fuels after 10 years.
However when liquid gas is combusted, no corrosive elements are created that could corrode the heat exchanger of the liquid gas heaters, so that for reasons of safety, a replacement of the heat exchanger is not necessary.
Knowing this, we are convinced that the safety and quality of the Truma products can always be guaranteed well beyond 10 years, which is why we decided to prevent the enactment of the new version of the “Technical requirements” for the benefit of our customers!
We commissioned a technical report on corrosion to assess the durability of Truma liquid gas heaters from the Research and Material Testing Institute for Civil Engineering, Corrosion Protection department, which came to a very clear result: “Heaters of this type can be operated without problems for 30 years or more, without any signs of leaks caused by corrosion”.
Based on this report we were able to convince the Motor Vehicle and Transport Authority to extend the periods of use of the heat exchangers in liquid gas heaters and the exhaust-carrying pipes from 10 to 30 years in the “Technical requirements for vehicle parts in compliance with §22a StVZO”.
This means that these costly replacements that have no technical relevance and do not benefit the customer are no longer necessary.
This now means that anyone who has installed a Truma liquid gas heater Trumatic C, E or S-K in their motorcaravan is freed of their duty to replace the heater exchangers and exhaust pipes over the next years.
Note:
The heater exchangers/combustion chambers in heaters in motor vehicles (lorries and motorcaravan) that were built between 1993 and 2006 must be replaced (after 30 years).
Older heaters have permission to operate in non-compliance and newer vehicle have an E1 code that relieves them of this duty. Example: A replacement duty for e.g. the year of construction 1993 would then come into effect in 2023.
The heat exchangers in caravans are not affected by this regulation.
Maybe the one or other Camper has made the not so nice experience of a leaking waterheater when started up for the first time after the winter.
A reason for this could be that the water was not drained from the waterheater. Or there was still water in the lines that had not been completely emptied because e.g. the caravan was not positioned horizontally.
Always empty the boiler if the vehicle is not in use during periods of frost.
To avoid frost damage to the waterheater, we advise the following:
1. The caravan should be positioned horizontally when draining the water.
2. First disconnect the power supply to the water pump (master switch of transformer)
3. Next, the water is drained from the tank and / or the water pump is removed from the tank.
4. Now open the taps in the kitchen and wet cell, and if your vehicle has pre-mixing valves, set these to warm.
5. Then turn to completely open the drain and venting valve, and pull out.
6. Now check whether the water (5 litres) drains completely.
Our tip:
Use a 5 litre bucket or tank with a filling level scale to check the amount of drained water.
7. You can also blow into the open tap – when set to warm – to blow out any remaining water from the device.
And finally, another bit of advice!
We recommend using agents with active oxygen and silver ions for cleaning, disinfection and care tasks . These disinfect effectively and are gentle on materials and the environment.
Anyone who wants to purchase a vehicle with an older Truma heater should note the following: The device should always be inspected by an expert or qualified workshop to check for faults. After so many years of use, it is possible that there may be gaps in the heat exchanger between the two half-shells that are pressed together with a sealing compound.
If the exhaust fumes (carbon monoxide) leak into the inside of the vehicle, this may, in worst case scenarios, kill the passengers.
Exhaust fumes can also enter the inside of the vehicle from corroded aluminium exhaust ducts. Since 1982 Truma has only fitted exhaust ducts made of stainless steel. Unfortunately, the exhaust ducts cannot be simply replaced 1:1 on heaters built before 1981 because they cannot be connected to the heat exchanger of the old heaters.
