Truma Combi - Can I get heating if there's no water in the boiler??

[@Bola-zu5ie]

Thank you for that. I am off to the lakes next week. Got a new van and was wondering how to heat it as I have only done ehu so far. Site has none of that but I have a full gas bottle and I have drained my system. Nice one.

Thanks for the video. Can the heating work on the 12v battery instead of has?
