Dear community, I need your help again. As in the description, I have a Renault-Trafic Evado II with a second battery under the driver’s seat. I want to retrofit an air heater. I really want to mount it outside. The effort between inside and outside seems similar. Outside, however, I have the advantage of saving space and possibly hearing less noise. I think I prefer to operate it with fresh air, not in circumferential air operation. n should of course be permanently installed, for a mobile installation would probably rather offer itself inside. I need an approved heating. I found this here: https://www.g-part.de/LF-Bros-E50-3KW-12V-Kit-EU-Version The well-known manufacturers are after all again considerably more expensive. If I would install them in mobile, however, can I also take the 100€ China-Dinger or what is your opinion about it? But also in this case I would have to drill through the base plate n to remove the exhaust gases directly and to tap the diesel feed, because I can only transport closed spare canisters, right? Now I have some general questions: Has any of you ever installed a heater in the Trafic in the one or other variant (where, like air supply/disposal, diesel feed) and can possibly help me with some photos (where I would of course ask even more specifically, WHAT interests me)? Of course there are already many contributions and endlessly he forums, I know. I am particularly interested in Evado, because it seems to be installed from the factory INNNEN, but with many other models more often outside – at least I have the feeling. I would be interested in two things in particular: When I drill through the floor plate (rail system), do I have to take out the floor covering first? How do you let the air flow into the passenger compartment during outdoor installation? Do you have an extra nozzle installed? Where? I thank you for your opinions. Greetings and a good day to you!
