heat in the garage

J

what are you guys using in the garage to paint with. I don't want to blow myself up. the only suggestion I have right now is to construct some kind of tent inside the garage to keep the fumes away from the furnace. I am getting busy and need to be able to do this year round
 
i use a large torpedo heater outside of my booth . burns farm diesel . when it is in the 30's i can keep my booth at 75 or above while painting . my shop never gets below 45 in winter overnight . it is insulated and holds heat well.
 
How many BTU's? I also am in a search of increasing the temp in the booth. I am thinking of a propane heater I could point at the inlet of the booth. I am trying to figure what average size would be required for the volume of air pulled by the booth.
 
i have a 150k btu with thermostat and a smaller 50k btu which sets outside the booth when painting. my shop never gets below 40-45 degrees at night and is not hard to heat during the day when temps are in the 30's. my booth stays at 70-75 degrees while painting.
 
Shine, don’t the fumes bother you, I have a 100k btu unit and its really nice and warm when I use it but after an hour or so I feel like I’m on cloud nine with a splitting headache and very dizzy. I use K1 kerosene for fuel.
 
i run farm diesel in mine without a problem. if they work right they dont make fumes. now if you let it run out of fuel it will cough out enough smoke to run you out . then you open doors let all the heat and smoke out and start over. mine runs about 5 min then shuts down for a while. if the end isn't red hot you have a problem.
 
You can use diesel in a kerosene heater?? how long does the tank last?
I am just looking for something to increase temperature in the booth, the shop is heated with natural gas. I don't want to have heat up the whole shop just to have some heat in the booth when a small extra heater could be used only when spraying.
 
why would it hurt the tank ? farm diesel is just dyed red to identify it . very little difference in diesel and kerosene . i have not bought kerosene in 30 years or so .
 
Perfect, and how much btu's are required?

I meant how long can a full tank last, fuel consumption.
 
my small 50k that i set outside the booth will run all day+ on 3 gals. the bigger ones burn more so i have thermostats to shut them down .
 
Last question, the fumes of burning kerosene or diesel don't contaminate a paint job? I have my eyes on a 120000btu unit, just want to make sure before I buy.

If that is happening you better have a look at the filters and get yourself a pressure guage and adapter pipe and check the pressure the pump is putting out also check the spark plug is giving good spark. I would hate to see you get hurt from an oversite, I also have a Carbon Monixide detector in my garage just incase CO is nothing to play with.

Anybody who dosen't have one go get one.

So long as it's burning clean you wont have a problem. Don't forget what I said above get a CO detector with it, that goes for you too Shine.
 
Ok, got the 135k btu kerosene heater today, ran diesel. I used while I was painting, and it worked very good. Brought the temperature in the booth up pretty fast, and even heated the shop in the mean time. No fisheyes in the paint, can't ask for more.

Shine, how do you get the warm air from the torpedo heater/s (outside the booth) to inside the booth?
 
the heater is setting outside of the booth doors. the heat is drawn in through the filters . the booth will stay at 70+ while i'm painting . i have a smaller one i set in the booth after the paint has dried for a while. it will come up to around 80-90 degrees for a few hours . overnight it will not get below 50-60 .
 
Ok, thats what I was looking for. My booth draws air directly from outside so in the winter its too cold to paint using that method. In the winter, I minimize my painting projects, but do have the option to draw air from the heated shop rather than outside. Shop has two options for heat, wood stove and electric. If I try and draw air from the shop with the wood stove going, it sucks the stove pipe right out of the chimney and all the ash from the fire and chimney with it. Electric works for the actual spray time. Once I get the booth, metal, and paint temps up to spray, I can spray with not a lot of drop in temp. Then after the booth has done an air exchange, I can get the tempreture in the booth back up to specs with very little time below spec. In the winter, its just a matter of using a different air supply (heated) to get the air into my booth.
 
You definitely need an air inlet somewhere to keep the shop from going too negative. I wonder how many shops out there are sucking combustion gasses into their shop without realizing it? Our shop has a swamp cooler mounted in one wall which has been retrofitted by removing the water sprayer and adding spray booth filters. The large squirrel cage blower keeps enough air flow coming in to balance the shop pretty well with the outside with the booth running, though it's still negative compared to outside. Luckily the furnace is a modern one that has a fan for forced combustion air. It won't let fumes back in while it is running.
 
My system works great for summer cause Im pulling warm outside air into the booth thru the intake filters. In the winter time, I close those intake filters and open intake filters located in a petition between the shop and the paint booth. That way the intake air is filtered and heated from the heated shop. But, I crack the big shop door on one side of the shop and the walk in door on the other side so the shop cools off pretty fast. It does not seem to get too cold in either the shop or the paint booth and once I am done spraying, I can get the temps back up within 15-20 minutes.
