I have one on my wood/coal burner for the shop.Mounted a 4 gal tank on the outside of the air jacket to keep the oil warm.Works good for a few days ,then the end of the drip tube gets coked up and wont drip.I used 3/8 pipe for the tube and feed it with a t,so that I can ream out the coke by pulling a 3/8 plug on the outside of the stove.I think its more trouble than its worth.
edit) it does smoke and stink a bit,might be a problem where you live,not for me,I dont have nieghbors!
