propane preheater
Another thread made me think about using the portable propane heater I
use in my garage to preheat my airplane. It's the standard metal tube type with the fan from Home Depot or Lowes. I've seen people simply attach a flex duct to the end of this type heater and blow the hot air into the cabin - poor man's red dragon. Any drawbacks? Thanks Dave |

If this is blowing the warm combustion gases into the cabin, plenty of
drawback. The combustion products are primarily carbon dioxide and water vapor. Lots of water vapor. The moisture can fog all the windows, or create frost on the inside of the windows if it is below freezing. OK on the engine, bad in the cabin. "dave" wrote in message . ..

Thanks Dave It may also render your CO detector completely useless. Aren't the combustion products are CO and H2O, not CO2 and H2O? |

It may also render your CO detector completely useless. Aren't the
combustion products are CO and H2O, not CO2 and H2O? Complete combustion results in only C02 and H20. Incomplete combustion, such as that in an (relatively) oxygen starved environment, results in the formation of CO (carbon monoxide). The trick is knowing wether or not you are having complete combustion. People have died as a result. Dave |

I've got a little ($15) ceramic heater that I put on the floor of the
cabin when I arrive at the airport -- and turn it on, of course. By the time I've finished preflight and such, the cabin is comfy. |

By the time I've finished preflight and such, the cabin is comfy. I think mine was about $20 but it has a nice thermostat, fan, and tilt switch to turn it off if it tips over. OTOH they are probably available cheaper. I set it on the floor in front of the seats and a bit under the instrument panel. Works great and no smell or after effects.

I'm not planning on using it to preheat the cabin. I'm wondering how
this is any different than a red dragon or the large pre-heaters that the FBO's use. Dave Stan Prevost wrote: If this is blowing the warm combustion gases into the cabin, plenty of drawback.

Bob,
I'm really only interested in using it to heat the engine. Dave Bob Noel wrote: In article , dave wrote: I'm not planning on using it to preheat the cabin.
