Selling my Thermobile AT 307. Unit has been used for about three or four years, it was bought as new old stock still in the box from a farm supply store. This unit is pretty much trouble free and is easy to start. Has a built in 15 gallon or so oil tank, built in circulation fan, and it does a good job of heating my 30'x48'x10' ceiling pole barn in the winter. Going to a furnace style conversion to make it easier to keep the shop warm all the time. This same unit is now sold in the states by Thermobile as a waste vegetable oil heater; a friend of mine bought one the same time I did and runs his on veggie oil and says it stays much cleaner than WMO. If you have a source of WVO and want a cheap way to heat with it, this might be your best option. Located in zip 46365, Northern Indiana, and I can help with hauling if necessary for a reasonable distance. Asking $950 OBO, these go for over $2000 new. Thanks!
