waste oil heater ,what do you know ???
well i have a 6000 sq ft shop .i work om motorcycles and have access to waste oil .i am considering a waste oil heater but wonder if a handy guy could build one .anybody build one or know where i could get plans to build one .
they are around 4000 bucks so it would be worth the time ....

My dad once worked in a garage where they used wasted oil for heat. They installed a Warm Morning coal stove (the old stand up kind). They ran a 3/8 copper line to a oil tank on the hill behind the garage. Once they got the fire going with wood, they cracked open a little valve on the copper line so the oil dripped right into the top of the stove. Man, that thing would get cherry red hot! Not sure how safe that would be, though. 0 -
I have a 140k btu Clean Burn brand waste oil heater in my shop. I gave $4400.00 for it 2 years ago. It burns about one gallon of waste oil per hour. For a 6000 s.f. shop you will need at least a 250k btu. unless you have low ceilings. I suggest buying a heater made for waste oil rather than trying to build one. We used the drip type method as mentioned above for about 5 years, til one day it dripped a little too fast while no one was watching it and we almost lost everything. We were lucky that we had a secondary valve mounted away from the heater to shut the oil off. The floor was covered in fire. If you choose to purchase a new waste oil heater, check with your tax man. We got back 50 percent of the purchase price on our state taxes over a 5 year period. If you want to know more about them, just email me.
BTW, a factory waste oil heater puts NO smoke out of the stove pipe. The drip method into a wood stove will smoke black and cover everything outside in soot. Been there, done that.0 -
The first one that we got was not much more than jimdeere's. It had a cast iron pot at the bottom that you started a paper diesel fuel fire in. When the temp got high enough oil was pumped in the pot a little at a time. 0 -
i second the post by forklift king...we have 3 commercial w.o.heaters i service at work, and havent paid for heat at those installations for over 4 years.
no smoke, great heat, about a gallon an hour fuel useage and they handle kero, tranny fluid, waste oil from the quick lube site as well as the old oil from all the pumps we run
seems the trick to the newwer ones compared to older models is a pre-heater for the oil to keep it thin just before the burner...and lots of filtering before that point
only drawback is you must clean out the heavy ash accumulation every 700 hrs of operation, less would be better for heat output0 -
We did what Jimdeere described, except some of the welders in my dad's shop had already built a HUGE wood stove. They did all their own maintenance and had LOTS of old oil. Mounted a 55 gallon drum outside the building, behind where the stove sat, ran a tube through the wall into the stove and dripped the oil continuously all day after the wood got to burning. Never had a problem, still doing it today. Works well, but could probably be made more efficient with some engineering. 0 -
I converted my wood stove in the shop over to strictly oil this year.
This thing runs great and heats up more consistant than wood.

backyard metal casting was a good read and has good ideas ,also lead me to the mother earth news article explaining how to build a forced air stove like i was thinking of .i just update my home furnace to a foreced air carrier unit .what i replaced was a large old heavy duty oil furnace that i thought i could convect to waste oil by adding an injection unit of some sort . the combudtion chamber is heavy duty so i thought it could be incorperated into a waste oil burner or vegtable oil burner as i has huge access to fryer oil here in the chicken wing capitol .
the earth news unit looks great but is a lenghty build . a local shop owner has one for sale used ,i am going to take a look at that one and see what the deal is .......0 -
MVP,
Could you please explain what we are looking at with your burner set up?
Are we looking down a pipe straight at the fire? If so wouldn't smoke/CO2 come up out of that pipe?0 -

What I have is just an old wood burner with a 5 gallon oil can set up abouve it on a metal frame. The oil is delivered through the copper tube and regulated by the valve at the oil can.
Oil is dripped into the metal can inside the old stove and the pipe you see is the intake that alows air to flow to the oil fire. The more oil that is allowed to drip creates more flame which creats more air flow which creats more heat.
When it is up and burning at a good rate, it sounds like a jet engine with all the air being sucked down the air pipe.
My shop is 24'x36' with 12' walls and this thing heats it well.0 -
mvp , how do you get the oil to fire to start it ? 0 -

I squirt a little lighter fluid into the can and light it. It preheats the can and then I start the slow drip and increase it as the can heats up.
Once it is going full out, which takes a good 15 minutes, the can glows bright orange.0 -
I am also working on a new seperate burner which I am making out of an old water heater tank.
My freind built one with the water tank design and it works really good.0
