Anyone have experience burning waste oil to heat a home or shop? I'm thinking about converting my oil system to accommodate waste oil.

We use a waste oil burner at the shop. Works great if you keep on top of the maintenance.

Just do he right thing and check local regulations.

Last winter was the worst winter we've had in 15 years. Only burned about 275 gallons of waste oil.

We have a reznor and it still works great. Ours heats the oil up before it gets ignited. I believe most work this way.
Ours burns any oil from gear oil to transmission fluid.
It hates the smallest drop of water and can really be a mess if coolant gets mixed in.
The burner is not your typical home furnace it can withstand huge temp changes due to the different types of oil. A home furnace burner would probably last a week and end in a fire ball.
It burns about a gallon and hour. So I hope you have a lot of oil. We assumed with the repair work we did and the few hundred cars we parted out a year would be enough to keep our shop warm. Wrong we were constantly on the hunt for oil. Several shops would let us come pump there oil but in all reality a real pain in the ass.
We usually just broke down and bought heating oil. Not cheap. Still it helped in keeping the yard clean and cars were broken down quicker since we had a clean way to deal with all the oils.

Yes ours needs major cleaning every year. One year the service man knew we had mostly been running diesel because it was much less work to clean.

Back in early 90's the engine builder we hired to make our engines used an old acetylene torch and compressed air to burn a flame about the size of a basketball inside an old pot belly wood stove. It burn very clean as the was no build up of any kind inside the stove. The exhaust out the chimney was clear the only thing one could see was the density change from the heat. They used pneumatic tools to run the hand grinders to port heads; because of that they had a compressor big enough to push the oil through torch and feed air though it too. I don't recall the size of tank they had to hold the oil but I'm pretty sure it would last more than a day. They mostly burnt 20-50 wt oil which was what we used in our engines.
