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!

Lol.. maybe in sunny CA but not up here in the NE. It's April 21 st and temps are still in the 40's here. I plan on heated seats for my 6 as I'm running headers. If I need heat or a/c I'll drive the Audi. |

I still commute on a bicycle when it's that warm. I dress for how I need to be comfortable OUTSIDE. Then the car is just warmer. Defrost is the real hassle, but a coating of RainX inside and out of all glass can help big time with that. |

Seriously? 40s? You mean above freezing or below? LOL That's not cold. I still commute on a bicycle when it's that warm. I used to commute on bicycle in any weather, and never knew what my girlfriends were complaining about in my 914 with no heat. (As an aside, it seems the same women who are attracted to the *idea* of a convertible in the early dating phase will the be ones asking for the top to be on later.) My wife simply wouldn't go with me on the motorcycle without heated gear. Once I tried heated gear, I was hooked. I did a ride without it and felt that being so cold affected my judgement and especially my enjoyment. In my Miata, having a good heater means I can leave the top open more than I could otherwise. So I'm happy to join the wimp club. I'd love to have a heater in my 914. Didn't need one today though. |

I completely understand and respect the wimp club, even though I often comment like I did for fun. I have a car with creature comforts too. I just won't go down that road with my 914. It's not the car for that. Bottom line that seems to keep being regurgitated year after year is: The best electric option is heated seats. You cannot heat and defrost your car from a 12v source. STOP trying. "Capn' I cannotta change the laws of physics." Heat exchangers just work. The most solid solution. The gas heaters can work great, you just have to be willing to go through a proper installation. Keep seeking another solution if you want to waste your time. Or come up with something that hasn't already been tried and proven to fail around here. (IMG:style_emoticons/default/dead horse.gif) |

(IMG:style_emoticons/default/idea.gif) You'll want to run #00 welding cables from the alt to the battery and from the battery to your heater... --DD For 1200 watts? Of course you would have to leave some of that behind for the other needs of the car. Step it up 110 with an inverter on the way and the wiring could be an extension cord. Which brings me to the Honda generator in the trunk idea. Small household space heater in the car. Another idea is to put the webasto in the right rear wheel well and duct into the existing air system. I want to go to WCR across the Rockies from me. Will I make it without a heat exchanger? The front fan works, and I can bundle up, but I do want to see ahead. |
