Truma 4E combi boiler
Truma combi 4E combines all the benefits of the combi 4 with those of an electric heater.
As apposed to the Truma combi 4 it also has intergrated heating elements and this allows you to run the heater at camp sites with the 12v supply unit without the vehicle battery.
Combi 4E uses very little electricity and the heater runs in gas mode for self-sufficient use, in electric mode at the camp site and in mixed mode when outside temperatures are low.
In summer the Truma 4E heats just water without running the space heater.
With intergrated heating elements for additional electrical mode heats the vehicle very quickly and uses little energy.
