Posted: Sun Dec 10, 2006 8:59 pm Post subject: Heater

I am planning  on installing an inverter behind the seat that will

connect to a separate  battery.  From the inverter I will run a small

electrical heater and  mount it under the dash.  Does anyone know why

I should not do  this?

 Hi !  Michael,

                         You can't get enough heat this way at least without flattening the battery real  quick indeed. Let's say you use a 500 watt heater. I can't see where you are  going to find smaller and I think you would need that anyway. So that 500 watt  heater will actually draw more than that out of the battery and the total output  of your charging system is probably only 170 watts and you need some of that for  other things plus you would not want to run your charging system flat out all  the time. Did you realise it works out to power a 500 watt heater you need to  draw  about 45 Amps ?

   Sorry  you will need to use a heat muff or water.

                                                                                        Rex.

Too heavy and it brings your cg aft.



My guess is that you'll have to recharge it after every flight or when it's depleated.  It'll then have to be a marine deep-cycle battery since you will be cycling the charge down so much.  Deep cycle batteries are heavier than normal automotive or airplane batteries.



A heat muff off of your exhaust is an option but a bit more complicated with potential CO2 in the cockpit.  A heater core with a small fan is probably the least complicated alternative and you won't have to deal with potential CO2 problems.

Ok Dave you asked for it  , now you say that my heat system has the risk of co in the cabin, first off it pulls from the right side of the radiator, and only the right 4 inches. I channel it right in through the hole for the bungee's in the floor.  Now, before I had spring gear I had the bungee gear, guess what, the holes in the floor where open, guess what else, in the summer time I had to close that area up as much as possible, why because I would get a bunch of heat from the radiator and would push up through the floor.  Now you can't tell me with your concern that you now should have a concern for co entering your airplane, I saw your video and you have spring gear.  Also, the old spring gear had a problem from exhaust hitting the leg going from the center of the plane to the wheel, that's what caused most of that gears problem, I can see it hitting the leg and shooting up into the little hole for the bungees.  I would be concerned for your situation when it comes to the exhaust as well.

I have a piece of alum bent at about 90 deg in front on bungees to deflect, 

fumes heat etc and protect the bungees from the same.



I have a scoop on backside of rad and it works gear -- no fumes but Carbon 

monoxide it odourless.



Heat Muff on muffler is the best heat aquiring mod you can make in my 

findings.  Although a fellow on this list Jim from Belle River Ontario that 

I have met a few times at flyins has a oil cooler plumbed in his coolant I 

think and he says it works great . It is mounted over top of runner pedals . 

He could probably tell you better on the performance of it.  He has little 

fans on it too.   BTW  His Kitfox IV  is "pristine" and with 912 weighs at 

about 600 lbs- so you know it a rocket !



I have very minimal airleaks as I have sealed up some like you have.



What dave are you talking to ?  >> I saw your video and you have spring 

gear.  <<



Too many Daves  LOL

Dave

Maybe Dave did what I did...I covered the bungee holes while I was 

covering my plane, because I had already made up my mind to go spring 

gear.

I guess I was refering to Dave with the ski video.  Yup, to many Dave's.

I would say the best thing to do is invest in a co meter, than you don't have to guess about it.

Dave,

   

  Could you publish some pictures of your heat muff installation? Also, anyone else who has used similar technique with a 582 exhaust system.

Ooops, I had spring on the brain.  everywhere I put spring gear twards the end of the message, replace with tubegear.  I meant to say the tube gear will have problems with the exhaust going up the bungee's and you have the tube gear.
