Alternative heating
Discussion
Gents
Anyone have any experience of decent alternatives to exhaust heat exchangers to heat early 911's? Mine is a 1969 car built for rallying, as a result, the heat exchangers and all heater related hoses are gone to keep weight down. All well and good, but at this time of year the car can get uncomfortably cold, particularly for the navigator, making it hard to concentrate. Also getting problems with demisting of windscreen. Any ideas that don't involve reinstating heat exchangers? The controls on the dash are still there as is the gubbins on the other side under the bonnet, but as it stands obviously only let cold air in. I believe there was a petrol powered heater made by Webasto, but it sounds a little too "bomb like" to me!

Mixed reviews and of limited effect but for £11 its better than nothing?

I just have misgivings about a heater that uses petrol as fuel and is installed right next to the tank! Particularly in a competition car, I don't think it would get through scrutineering apart from anything else. Electric would seem the way to go, but the ones on the market all seem a bit crap.
The problem with electric heaters is their power source - the alternator. Let's say your alternator is rated at 100 amps - that only 1200 watts. If your fuel pump and lights and driving lights are using perhaps 3-400 watts that only leaves you 800 watts. That's not a lot of heat in a moving car where cold fresh air will be coming in through vents and leaks. And any which way an electric heater needs to be wired to the battery to be capable of much help - through a lighter plug you'll struggle to get more than 15 amps = 180 watts.

The electric heaters are useless,front heated screen is good.I have been running as have porsche petrol heater for years,no problem with scrutts either so far!The petrol heater can be fitted into the smugglers box,i have seen flexy pipe fitted run inside because of no heater channels,connected back up to heat exchangers etc.

Have you been over to Impactbumpers or DDK forums? Lots of bods over there who run very similar 911s.Anyone have any experience of decent alternatives to exhaust heat exchangers to heat early 911's?
