Friend of mine that owns a muffler/welding/repair shop has a regular wood stove and uses a small 1/4"? Copper line to feed a drip of waste oil onto the already burning wood. A valve on a waste oil container that sits higher than the wood stove allows him to adjust the feed to a drip. He said if he feeds it too much not only does the stove get pretty hot but it puts out black smoke which results in a visit from the fire department.

I have heard they can be high maintenance. A good buddy of mine has a repair shop and and chose a regular furnace over the waste oil version because of it.

Why even think about burning used motor oil? Burning it disperses contaminants, like lead and other heavy metals, through the air. And once it is burned it is gone. It can be recycled and re-used.

I used to own a heavy truck and trailer shop ,and went through 900 litres of oil a week .The oil companies would give me things to use their oil ,one was a clean burn furnace .Because I had full control over the oil I burned (I was not buying it from someone else ,or randomly accepting it from others ) I had very few issues with mine .Trick is to use the cleanest oil possible ,no antifreeze ,water ,etc .
Mr curious ,do you not believe using used oil for heat instead of purchasing new oil is not recycling it ?I had a very large shop ,200x300ft ,it goes down to -40 here often in the winter ,that would of cost a lot of money to heat if it wasn’t for the used oil .
I wouldn’t bother doing it if I didn’t have a real good volume of oil to play with ,the furnace was expensive to purchase outright ,and I have worked in other shops that had them and many had nothing but troubles stemming from poor quality contaminated oil .Transmision shops did well with them .I had an interest in the furnaces ,and understood them well enough that I would often fix them for other people that had them ,depending on where you are located finding someone competent to work on them could be a struggle ,also parts availability was an issue sometimes .

Thanks guys. Sounds like something more suited to a commercial application than home or hobby shop. I was a bit surprised it hadn't been mentioned here before, guess that's why.
