Grease Gun Shop Heater
 ✖  |
"It's amazing how much heat it puts out and how cheap it is to run. Works better than any portable commercial heater on the market," says Glen Teel, Hays, Kan., about the propane-fired heater he made out of miscellaneous parts, including a grease gun and zerk used as a fire nozzle.
"I got the idea one cold day while working on a motor in my shop by my-self," says Teel. "I was trying to warm up the shop with an old wood stove. It was a big unit that took up a lot of shop space. To keep the building warm enough you were so busy keeping the fire going you couldn't get any work done. I decided there had to be a better way to stay warm."
Teel didn't want to spend the money on a commercial gas heater because of the. cost and because of fumes given off by the heaters, so he decided to design his own clean-burning unit. He used a piece of stove pipe, an old heater motor, spark plug, miscellaneous valves and electric controls, as well as the grease gun and grease zerk.
"One gallon of propane will last over 10 hrs. No one who's ever come into the shop while it's burning has smelled any fumes. It keeps the building so warm it melts snow off the roof," says Teel.
The body of the heater consists of a short length of stove pipe with a 2-lb. coffee can attached to close off the back end. A 1/4-in. dia. gas pipe is inserted through the bottom of the can into the center of the stove pipe. A grease zerk, with the ball and spring removed, is inserted into the end of the pipe, which is surrounded by the barrel of a grease gun. A 3-in. dia. metal cone is positioned 3 in. from the end of the grease gun barrel. A spark plug igniter, energized by a Model T coil, mounts just above the end of the grease gun barrel.
When gas is turned on, the spark plug ignites it as it shoots out of the grease zerk. The barrel of the grease gun directs the flame into the cone, which bounces the flame backward to bum up all unburned gases. An old auto heater blower, mounted at the rear end of the heater, then forces heat out the end of the stove pipe. "The heat it produces is extraordinary. The cone burns everything up so there's no fumes and the airflow produced by the blower makes it burn real hot and gets the heat out into the room. Without the blower, you wouldn't get much heat. You set the flame by controlling the flow of gas out of the propane bottle. My heater doesn't have a safety shut-off valve or regulator but they could easily be added.
I have to be real careful when lighting it not to let in too much gas before ignition, and when setting the flame you can't let in too much fuel or the heater will melt itself down," says Teel, who's considering putting together plans detailing how to put together and safely operate his home-built heater.
