Gas fumes
Fumes can build up from stored gasoline, or vents from fuel cells in older cars lacking charcoal canisters. Gas fumes settle to the floor so keep all gas-burning appliances and electric motors at least 18" from the floor.
 Types of heating
Utilizes the heat that is contained in the earth or bodies of water and through the use of a open or closed system brings heated water into the structure whereby the heat is extracted by a water furnace (water-to-air)or in-floor circulation.
 Closed loop
Is a sealed system, whereby water is pumped through the pipes and is heated by the earth or lake water and the heated water is brought back into the structure.
 Open loop
Takes water from the ground or lake and circulates it back into the structure through pipes and tubing.
 Radiant heat panels
 Sealed combustion space heater
Direct vent,these unit are usually 90% efficient or better. Pulls combustion air from outside, and returns exhaust gasses to outside. Burners are enclosed and does not use inside air for combustion. These units are better for use in garages and shop space where chemicals, gas, paint or other flammable products are used and stored. Warms up quickly.
 Open combustion
Usually 80% efficiency. These units do not have a sealed combustion chamber and have open flame. They use indoor air to supply the combustion process. You must be careful when painting, or storing flammable products.
- In-floor hydronic heating must be left on nearly all the time because it's slow to heat up. This type of system requires the use of a boiler. It's a great way to heat shops, painting areas or chemical storage spaces because the boiler is usually located elsewhere, i.e. inside the home or an enclosed utility room. You can heat your house and garage this way because there is no air transfer.
 Supplying gas to heating unit
Make sure you are supplying the correct type of gas to the unit (you do not want to supply natural gas to a unit that is designed for propane).
A gas burning appliance must be vented to the outside. Care must be taken to ensure the proper type venting pipe is used. It's also important to maintain minimum distance from combustible materials. Most units require vertical venting with at least 5 feet of vertical piping, though some newer units can be vented horizontally.
 Combustion air
When utilizing an open burner design heating unit, an air supply is required for it to burn and vent properly. The air is taken from the outside and should be a constant supply; merely opening the garage door periodically is not sufficient. Usually 4 to 6 inches depending on the BTU's produced. If there is no combustion air, the system will begin to consume the oxygen directly from the breathing air and pull the entire space into negative pressure. The exhaust gasses may then spill out of the combustion chamber.
 Distance from paint
Keep heaters a safe distance from paint. When painting it is best to turn all power off to the heating unit until fumes are ventilated.

When heating, money will be saved by insulating.
One option is to insulate with fiberglass batting, then cover the walls with inexpensive drywall or fiberboard.
- Install a carbon monoxide detector if relevant.
- Don't paint with a gas heater in the garage.
 Inexpensive heating solutions
- Used mobile home heater
- Wood burner
- Outdoor wood burner that heats water, which flows through a radiator, which has a fan blowing air through it
- Portable kerosene, oil, and propane heaters may put moisture, soot, and carbon monoxide into the air if they're not in proper working order and adjusted right. If there is good combustion, there will still be carbon monoxide present in the exhaust.
- For portable heat, mount a heater securely on a dolly. Use a flexible supply line if gas powered.
- If you have a basement or partial basement under your garage, you can place a heater in it, effectively heating the ceiling, which would be the floor of your garage.
- Consider putting two inches of new concrete on your existing floor, and install an in-floor heating system before the pour.
- A design that is being noticed is building a concrete box about a foot away from the shop with a stack coming out the back leading into the shop and another stack out the top for fumes. The rear stack's low exit from the box will transfer heat without bringing harmful fumes. This also aids in safety with the fire being contained in the box and not directly in contact with the building. Old chimney pipes work well for both passages.
