Greetings once again from Munich!
It’s cold over here when the sun goes down, not to mention nice days in March, April, October and November. I need heat, and I don’t have it because my engine has headers. I am thinking I will need a high output alternator if I’m using only 12v in order to get the necessary output. Is this somehow a bad idea? (IMG:style_emoticons/default/idea.gif) Questions: How would a e.g. 50 amp alternator affect power and gas mileage? Would it have any effect on the electrical system? Can you recommend a heater for this application? Other suggestions on how to best get heat into the cabin without heat exchangers? Here is an article on PTC (positive thermal coefficient) heaters... https://link.springer.com/content/pdf/10.10...-11628-5_51.pdf Thanks for your feedback and advice!

Played with electric,didn't spend a lot (luckily),total waste of time,too much current draw as mentioned ,I use heater fan set on full speed for demist and have deleted heater control,works good enough .
Not really that cold here but would be different in Germany. |

Not really that cold here but would be different in Germany. I was thinking about using a high output alternator for this purpose and taking the power straight from that. Honestly don’t know much about the feasibility of this possibility. Still waiting for comments on THIS in particular. Aren’t there 12v heaters out there that need about 50 amps to put out about 10,000 btu / 3000 w or similar? (IMG:style_emoticons/default/confused24.gif) |

(IMG:style_emoticons/default/confused24.gif) Your money go ahead, but VW guys have been chasing this for 60+ years with poor results. Even big modern alternators can only handle around max 800 watts. There was a guy last year that bought a $200 espar china copy diesel kit from evilbay, did he ever install it? (IMG:style_emoticons/default/confused24.gif) |
