Diesel "parking heaters" #2

[cfz2882]

Had a post on these devices a while back:meant for warming truck cabs,boat cabins.etc.these heaters run on 12 or 24v dc and burn diesel fuel in an enclosed,forced draft combustion chamber.Been using a couple of these to heat a 12v backyard building: very pleased with the performance so far using a Russian made Autoterm 4D- 4KW of heating power and very reliable though i had to partly dissasemble and clean a screen around the "glow pin"ignitor when screen became fouled when i tried a mix of diesel and used motor oil The fan motor,BLDC on the Autoterm,runs about 3000-4500 RPM. Combustion air and burner exhaust are piped from outside the vehicle or building,so very safe.Have also used a 2D Autoterm and a couple Chinese made Vevor ones.The chinese heaters are real cheap:~ $125

put to a good test...

was forcasted to get bitter cold temps last night so left the heater on-was afraid the diesel fuel line might "gel up"but was delighted to find the heater still working despite a morning temp of 28* below zero-and heater kept temp at 58* in the moon unit Also a couple 50w MR16 halogen lamps were left on to help a little. Sunny and 18 below as I write this at 12:45...

A business nearby has one in a shop and it works very well. They have a larger tank and use kerosene for the fuel as diesel is just dyed kerosene they sell for a higher price per gallon.
