The waste oil heater is small prefabricated stove perfect for premises to 50 sq/m. The so called Spark model is inspired by russian designs. Tested with reduced air flow it burns 400 ml of oil for 40 min. The burning chamber can handle up to 3 litres with one loading - 5 hours non stop working. You can pour more oil while burning. It's safe becouse the oil do not burns, his vapor do. Optional drop feed from oil tank can be installed.
The stove is lightweight and cheap, easy to operate with only three replaceable parts. This means that the oil tank, the perforated burning chamber and the chimney box can be replaced, helping cleaning the ashes. Checkout the video.

<p>dear friend, </p><p>do you have any clues on how to use pellets in it, gravity feeded?</p><p>Regards</p><p>Chris</p>
I built one and looking at ur video it appears to have no black smoke. But I get occasional black smoke and doesn't appear to be a really clean burn.
<p>Well, it's waste oil and didn't think to make it eco friendly. :) It is <br> simple to make with replaceable parts. It burns less oil than russian <br>model on the net. Small workshops, garages will be happy to have one. I <br>already made few for clients. Now there is a new design with build in <br>fan. I simply want to register and patent it in US, because it's very <br>simple and efficient. If you heat 50 sq/m premise with this stove, the <br>new model will warm up almost 100 sq/m. And it can be turned and used as <br> wood, pellet, brickettes, coal burner etc.</p>

Does the bottom pipe need those small holes or could I use a pipe without any holes?
The small holes suck air right where the oil vapor burn and if the holes are missing, the air must travel all the way from the triangular hole lacking lots of clean burning. The holes also makes the draft way better and stronger. This holes are the slowest oparation you need to do. Do not make lots of them. The pipe is 30 inch long, 5 inch wide and it have 20 holes.
