Thanks Jerry, does the little heater move the air enough to keep the windows clear? The largest I see is 300 watt so I guess it should be no smaller for sure. Do you know how many watts yours is? Thanks.
Is your machine liquid cooled or air cooled?
It is liquid cooled.
I was thinking the same, you should look into one that uses engine coolant. I remember others say with it running you almost melt inside the cab it can generate so much heat! You just need to plumb it into your engines cooling system.
I have seen heaters that use the coolant on e-bay,I think they were about $75 but not sure. I will look at my electric ones in the morning , they don't put out much heat and they sure suck current from the alternator especially when you have all the lights on also.
I can't seem to find these heaters on ebay or anywhere, anyone know what they are called, I may be searching with the wrong keywords. I can guess that even if a 300 watt electric heater would work it would be quite a drain on battery/alternator with all lights on. I am more concerned with fogging and frosting than being cold.
300 watts = 25 amp @ 12v. Most alternators will produce upwards of 50 Amps, so you will be fine. The most efficient way is the heaters that plumb into your by-pass hose in your cooling system. The heat is wasted in the radiator so its essentially free heat.

go to Ebay motors and do a search on[ truck heaters]. Im looking for one also so Ive been searching.
I took a heater core out of an ford truck and a dash fan out of another old truck and made a heater for my Mustang. mounted it betreen my legs with the fan blowing on the door. worked great, but the trick to keep from fogging up is to have outside air feed your heater, mine came from a crack below the door. Most cars and trucks feed the heating system through a vents. unless you want the sauna effect. cracking a window might work too. I hooked up to the existing fitting on the block for stock heater, you can mount a gate valve on one of the hoses to regulate heat and I piggy backed wiring to to the fuse block with a toggle switch and in line fuse. I took it out in the spring and installed it when it got cold.scott
The used computer cooling fans you see in surplus parts places are 12 volt and might be good for defogging the window. Some computer shops will give you one of a junk power supply.
Thanks for all of the replies.
These folks have them in Mi
