No, the Truma Combi system requires water to operate properly. The water in the system helps to transfer heat and ensure safe operation.

It is important to always ensure that the system has sufficient water before running it.

There could be several reasons why your Truma heater is not working. Here are a few common issues to check for:
1. Check the power source: Make sure that the heater is receiving power. Ensure that the power switch is turned on and that it is plugged into a functioning power source. If it is powered by propane or gas, ensure that the fuel supply is sufficient and turned on.
2. Check for blocked ventilation: Truma heaters require proper ventilation for combustion. Ensure that the air intake and exhaust vents are not obstructed by debris, dirt, or snow. Clean any blockages that may be preventing airflow.
3. Check the thermostat settings: Make sure that the thermostat is set to a temperature that requires heating. If it is set too low, the heater may not turn on.
4. Check the battery: If your Truma heater has a battery-powered ignition, ensure that the battery is not dead and is properly connected.
5. Check for error codes: Truma heaters often have error codes or LED lights that indicate specific issues. Consult the user manual or contact customer support to identify the meaning of any error codes and troubleshooting steps to resolve them.
If none of these steps resolve the issue, it is recommended to contact Truma customer support for further assistance or to consult a qualified technician for repair.

The heating time for water in a Truma Combi-4 can vary depending on a few factors, such as the initial temperature of the water, the desired temperature, and the power source.
