Quite late to join this conversation, but I need some help. When we bought our unit the salesman knew nothing about the Truma Combi unit. Had the installed show us the basics.
I have a bunch of questions, so please bear with me. A previous post said that on the ECO setting with both gas & electric selected the unit uses electric. Is that true of other settings?
Do you turn the unit off before you unplug from shore power and get on the road? What is the benefit of using gas & electric. Why not just run on the campgrounds power?

Thanks a bunch.

yes turn the unit off before traveling.

and - to heat up the air (or water) propane is fast, and has a big thermal energy.

the Truma Combi is either 800 watts or 1800 watts... if i recall correctly - depending on the setting - but 1800 watts (like a hair drier) isn't enough to heat up an RV from a cold blast of air as you enter, for example.

so you use both propane and electricity. The propane gets you to your target heat. The electric keeps you there.

also - you can find the manual on the internet and read it. :-) for more questions.

I'm no expert but I do know the above to be true.

hope this helps.
