Benefits, tips and answers
General
Yes. With Combi and Trumatic E heaters, the heating function can be used without a problem whilst driving.
In the case of Trumatic S heaters, however, the heating function can only be used together with a cowl top, which must be installed freely in the air flow. Truma recommends cowl top T3 or cowl tops T1 and T2. Otherwise, the flame may burn back and cause damage to the heater.
Additionally, the cowl top must protrude at least 10 cm beyond any additional roof accessories (roof boxes, ski racks, luggage racks, etc.) so that the heater can function without problems.

If your heater features an auto ignitor, we recommend replacing the batteries every two years or when the ignition frequency becomes slower. Make sure to use only leak-proof battery types.
Truma S
Yes, the dimensions have changed. The depth of the base is now lower.
The new S-heater can be installed in the same position as the old one if the old unit is a S 3002 built after construction year 05/96 or a S 5002 built after construction year 05/98. The cut-out in the floor will need to be modified if the models are older.
Please note that the new cover of the control panel bracket is higher and in some cases the cupboard door may need to be modified. The contours and the depth of the base have changed slightly, this may mean that an imprint of the old base may still be visible on the floor.
Due to the lower installation cut-out, it is necessary to fit a strip to ensure that the S 5004 heater functions correctly when installed.
Always contact your nearest dealer when replacing units.
Due to the new operator-friendly design, almost all parts have been modified which means that the old parts cannot be used for the S 3004 and S 5004. Also, it is not possible to use the TEB-2 / TEN-2 / TN-2 fans for the S 3004 / S 5004.
No, this is not possible or permitted because the dimensions and connections have been modified.
Yes, the warm air parts and cowls (apart from the cowl top T1) can still be used.
Trumatic S
If you remove the cover from your heater, you will see a short piece of exhaust duct. If the exhaust duct has a winding, it is made from stainless steel. If it does not have a winding - only small grooves - this means it is an aluminium duct and needs to be replaced. Please note that the duct may only be replaced by a specialist (such as a Truma service technician).
Whatever the case, however, increased temperatures in the wardrobe and at the exhaust duct do not pose a risk of fire.
Combi-Modelle
With the Combi 4 (E), no more than one warm air outlet or warm air line may be closed completely. However, in all cases it is better to use all four warm air outlets.
Individual outlets in the same duct may only be closed if T or Y-pieces are being used and the heat is being conveyed to another warm air outlet that is open.
If the living area is being heated and the boiler is being operated (during winter operation), a water temperature of 60 degrees is reached after around 80 minutes.
It is possible to heat up the water in electrical operation alone (i.e. entirely without gas). The heating time in electrical operation is around 45 minutes.
The heater only heats the boiler (in summer operation, at a 2 kW level only); the circulation fan does not run.
The water tank should be descaled from time to time.
Citric acid must be used for this purpose. This can be fed into the device via the water inlet. Leave it time to take effect and then rinse out the Combi thoroughly with fresh water.
For sterilisation and decalfying purposes, we recommend the Truma AquaStar cleaning and preservation system.
Please do not use the water from the Combi as drinking water.
Trumatic C
With the Trumatic C 3402, no more than one warm air outlet or warm air line may be closed completely. However, in all cases it is better to use all four warm air outlets.
Individual outlets in the same duct may only be closed if T or Y-pieces are being used and the heat is being conveyed to another warm air outlet that is open
If the living area is being heated and the boiler is being operated (during winter operation), a water temperature of 70 degrees is reached after around 80 minutes.
To enable the water to heat up faster, we recommend using our electric heating collar too. This requires a 230 V power supply and has a heat output of 450 W. It also enables the water to be heated up entirely electrically (i.e. without using gas at all).
The heater only heats the boiler (in summer operation, at a 2 kW level only); the circulation fan does not run.
The new control panel has a modern design and features an additional function. It has a switch setting that is designed for operating the heating function without the boiler having been filled.
This means that the water is automatically heated up too when the boiler is filled. In this case, the water temperature is dependent on the heat output and length of time it takes for the device to heat up the room. This function allows you to have heated water but only consume a small amount of gas.
If you upgrade to the new control panel, you will also need a remote sensor (available from your dealer).
The water tank should be descaled from time to time.
Citric acid must be used for this purpose. This can be fed into the device via the water inlet. Allow it to take effect for the appropriate amount of time and then rinse the tank out thoroughly with fresh water. For sterilisation purposes, we recommend the Truma AquaStar cleaning and preservation system.
Please do not use the water from the Trumatic C as drinking water.
