Frequently Asked Questions

What type of ventilation is recommended for gas-operated heaters?

It’s always a wise standard operating procedure to keep some level of ventilation constant in your work area while operating a propane heater. While modern-day propane heaters are equipped with many fail-safe features, the exhaust of propane, carbon monoxide, is a colorless, odorless gas that can poison and lead to death in high doses. Since most spaces being heated tend to be larger than the space heater’s effective range anyway, having a warm corner with a backdraft encouraged by an open window or two is precautious enough to ensure your safety in chilly environments.

What other safety precautions should I take before operating a garage space heater?

Aside from the dangers of carbon monoxide poisoning, there are several further precautions necessary for electric and gas heaters’ safe operation. Gas heaters can also leak propane if the line is punctured. While propane alone is odorless, manufacturers add mercaptan to give the gas a ‘rotten egg’ type smell, alerting you to ventilate immediately. In regards to electric heaters, never overload an outlet with too many electric components. Space heaters require a huge electric load, especially at high temperatures; plugging power tools or powerful speakers into the same outlets can cause a surge, which may permanently damage any unprotected components.
