Portable Large-Space Gas Heaters
 |  |  |
Style A | Style B | NEMA 5-15 |
Built for big jobs, these are powerful space heaters.
All have a safety shut-off that cuts the gas supply if the flame goes out.
Propane Heater—Propane heaters have a regulator with a NGO connection (the same connection between your gas grill and propane tank).
Knob Control—On heaters controlled with a knob, turn the knob to adjust heat output.
Thermostat Control—Heaters with a built-in thermostat allow you to control the temperature.
Style A—Style A heaters use convection to circulate warm air. They have a pilot light ignition and do not require electricity.
Style B—Style B heaters have an electronic spark ignition and are good for drafty areas where a pilot light could be extinguished.
