Like another comment mentions you should do some more heat exchanger pipes and also with your excess heat you could probably do a sterling fan which operates off the heat and will push the air through the pipes for the heat exchange ...great job and great video

I have one almost just like what you have I made it so I could close the door I used exhaust wrap and flat strap and bolted it the heater side it works great to seal the door up

I'm going to be building a setup kinda like this soon. Perhaps I'll get it made before Christmas. I can get my hands on plenty of used oil between my stuff at home and where I work. I run a grader and we've got a second one also and two tractors. So lots of used oil to get me through a winter even in Canada. Lol. My grader alone I'd get about 350L/93 US gallons roughly in a year.

I know this is an old video. I’ve been looking at building an outdoor one so insurance doesn’t have an aneurism. Love the build and it’s nice cause our hot water heater was just replaced. I subbed and appreciate the time you spent to do an efficiency test.

Great set up. I built one exactly like that only difference a few more heat exchangers. I don’t have a burn chamber cap like you have to swirl the flame, but that is an option I can always add. I reinforced my door with 1/8 inch thick by 1 inch wide steel strips. One piece on the inside of the tank the other piece on the outside edge of the door. It really seals the door well and when you close it you can really hear it roar when it’s burning. I also have a half inch copper feedline inside of a 1 inch black pipe for the feed, The air around the copper pipe keeps it cool so that it does not get gummed up with burned oil residue. Once again great job, you will really appreciate the amount of heat that they put out especially on a really cold day. 😬👍

if you lived in a cold climate and were burning around the clock you would need 10 gallons a day or 300 per month in the winter on 2400 sq feet shop...seems like a lot of old oil would be needed. If the oid was free and you had an endless supply of it...and a big tank to hold it. Would be a great idea

If you can keep it regulated to a small stream 5 gallons may do it The problem I've had with mine is as the shop becomes warmer the oil becomes thinner and flows faster so I have to keep an eye on it.

What you are making is a feed rate limited burner, or it should be used that way. In short if you ever over feed the oil you end up in a situation where there is more than enough fuel and the limit is the amount of oxygen it can get and how hot the oil is. You've made a bomb. The goal is to never be able to over feed the oil and create pooling. The best way to handle this is by line sizing, you could use 1/4" or 1/8" line prior to the sight glass to achieve proper flow so that you can see that the tubing isn't plugged and yet you never have to worry that someone could accidentally open a valve too much and allow the fuel to pool.

@@randysdiy2102 I ran Grignard reactions before that are similar to burning oil in that if it gets too cold the reactants can pool and when it begins to warm up you have a runaway reaction (a bomb). Here if the oil is allowed to pool significantly and it continues to burn the oil can burn faster and faster until it burns out or explodes due to all the oil vapor and oxygen blending. The boiling creates an atomized mixture of fuel and air in a container that is already burning. Adding too much oil can cool the oil in the burner and now it becomes a heat controlled reaction because there is more than enough fuel but it's not hot enough to burn but you wouldn't know that because you can't see inside and even if you could the damage is done. Hope that it burns out. I think for added info you can look up Grignard reaction and see how they deal with it's explosive nature.
