There are companies that make a furnace or boiler made specificly for waste oil burning. There are a few that make just the burner, that you can put on an existing unit.
used oil furnace = previously owned furnace that burns commericial fuel oil?
Used oil furnace = funrace that burns old motor oil as heat?
I'm a little confused base on a couple replies please striaghten me out
thanks
Yeah, Krewat and others, Modified hit it right on the head. I must have have a brain cramp when writing that one . I have a fuel oil furnace that was previously owned. It doesn't burn old motor oil. I wish I had one, we go through alot of oil around hear.
My buddy has one like that - he likes it alot. There is a filter on it. I believe the water, etc. gets run right throught it.
I have a natural gas furnace in my garage. I can tell you this is about the worst type of heat. It heats my garage up quick but the gas prices are killing me so I keep it at 50 all the time and just wear more clothes. I'm sure the electric bill is going to kill me this summer too since I have a/c out here as well.
I looked at waste oil furnaces but they are pretty pricey. According to my calculations, it was going to take between 7 and 10 years for it to pay for itself. Here's a good link on waste oil furnaces though.
I converted a oil furnace from a mobile home for my shop. picked it for $50 installed myself and you can work comfortably in a t-shirt when it's below 0 outside. Warms the whole garage up in about 15-20min(25'x30' garage). It's great because a mobile home furnace blows the heat out the bottom to keep the floor warm. It's pretty efficient also, burns about 5 gallons in a weekend.
I have a 110K BTU space heater (the jet-engine type)... burns white kero.
I crack the door open, stick the nose of the thing into the garage, and turn it on.
I have a wall thermostat for a house furnace hooked up to a relay, so I can regulate the heat - small garage (12x15 or so), but you get the idea. After everything in the garage is warm, the heater hardly comes on more then a few minutes every 10-15 minutes. That's down to 20 degrees F or so. Garage is so well ventilated I don't need to worry about the carbon dioxide or CO - I also have a CO detector on the wall with digital readout
Once everything inside the garage is warm, it doesn't matter how much heated air is lost, it still "feels" warm.
Smells like kerosene slightly, though.
Other than that, take your pick of heating methods. Wood stove? Waste-oil burner? Propane?
No ideas about efficiency, but cost-effective is a better choice unless you want to be "green"
BTW: My 110K BTU space heater takes .9 gallons of fuel per hour. With the thermostat, I can get that down to probably .1 gallons per hour, with an initial .9 gallons to heat the place up. So, in an 8 hour day, I use 1.8 gallons. I recently spent $2.79/gal for white kero. That's just slightly more than $5 per day. $150/month. If that was 24 hours a day, that would be $450/month to heat a 12x15 space. I spend $100 a month heating my house with NG and baseboards under the same conditions.
Just for comparisons
Anyone else with real $/hr cost of heating a garage? (and describe their condition and size too!).
I have 5000W electric forced air heater and it keeps my 12oo sq ft garage comfortable but it never turns off because it won't get warm enough to allow the thermostat to do so.
I pay $.035/ KWH so...... lets see.... 17.5 cents an hour for heat in garage
