Sounds like a perfect application for one of those annoying little Honda generators that we always seem to get stuck next to when camping...? Annoying and expensive! The Honda's go for around $600 and the Coleman's about $450. There's a DuroPower line that runs just north of $100 but that price makes me take a step back. Marco |

That might not work so well in an application like this. If he has the 250 watt heater and runs it for 3 hours then he has removed 750 watt-hours of energy from the battery (plus change). A typical solar panel charger is meant for trickle charging and they only put out something like 10 watts or less, although I've seen some up around 20 watts. That means that it will take 75 hours of charging time at 10 watts to replace that 750 watt-hours, and that's at 100% efficiency which, as well all know, doesn't exist. There's a guy with a solar-power setup on the ramp but I've never been able to run into him to pick his brain. A friend heard that he has his thing patented so I might get little info other than a price... I researched the solar powered thing briefly but stopped after the numbers on the napkin hit 4-digits to the right of the dollar sign. Most of these deep cycle cells are looking for a charge at around 20 amps for 10 hours or so to bring them up to full charge, and then a float charge to hold the terminal voltage around 13.8 volts. Either a generator or a propane-fired pre-heater is the way to go here. Yeah, I think a generator is the ideal thing. Plus, I can use it for many different applications as well. |

If you can setup some sort of remote starting for the generator, you can get started warming it up or just start the generator and go get a cup of coffee. You don't want to be hauling hundreds of pounds of acid filled batteries around. That's a good point about the acid batteries. Charging would be a constantpain as well. I think you guys are convincing me to go the generator route... |

I've been reading this tread with some interest, but I am fortunate in
that I have electricity to my hanger. What I'm curious about is the cell phone or pager thing to turn on a heater remotely. Has anyone done that, and how so? One thing that came to mind with pagers is that alot of times they will beep something like once a minute as a reminder if you don't push the button when it goes off, does that mean that any application would be switching on and off likewise if you used a pager? -Ryan Wubben Madison |

There are others on the market I believe. There's also a $15 ThermoCube that turns on the outlet under a certain temperature. Sporty's has it. Marco |

I think it would work for someone who flies infrequently. Solar power does have a significant upfront cost - but is essentially free thereafter. Personally I have had good luck with a couple of ceramic "cube" heaters with dryer duct hoses attached to the business end - but have been fortunate to have had AC available. David Johnson |

Annoying and expensive! The Honda's go for around $600 and the
Coleman's about $450. True, but you'd have something that would be truly useful in other applications all year long. (Like a power outage?) Not sure what else you could do with a solar-powered Tanis heater contraption... ;-) -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Winter means thick overcast, how well will your solar panels
work in the cold with dark overcast and short days? "Jay Honeck" wrote in message oups.com... | Annoying and expensive!

Winter means thick overcast, how well will your solar panels
work in the cold with dark overcast and short days? I don't know. However, winter isn't always a thick overcast, especially at this time of year. When it gets really, really cold, we are often under a big bubble of Canadian high pressure. The sky turns cobalt blue, the winds die down, and the temperature plummets. Today was an absolutely perfect day to fly, if you don't mind the cold. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination |
