Safety of Catalytic Heaters

A catalytic heater is a portable heater that runs on propane. They are used to heat indoor and outdoor spaces and are commonly used while camping. There are number of safety issues surrounding these devices.

Adequate Space

• Ensure there is sufficient space around a catalytic heater before it is turned on. This especially applies to indoor uses. Due to the cold temperatures campers face during winter camping, it is tempting to use a catalytic heater inside a tent. This is not recommended unless the tent is very large (i.e. much larger than a five-person tent). If the heater tips over during the night, it could burn the tent down very quickly.

Service

• It is important to keep all fuel lines and fittings clean and free from damage and wear. Always inspect catalytic heaters for dirt, fuel residue and damage before use, especially if it has been a long time, i.e. a year or more, since the last use. During setup, check for leaks by rubbing soapy water over all of the fuel lines. If bubbles begin to form, a leak is present.

Carbon Monoxide

• Because catalytic heaters are flameless, they do not produce much carbon monoxide, which is extremely toxic to humans. However, it is still highly recommended that catalytic converters only be used in well-ventilated areas, i.e. areas with a fresh air opening of at least 39 square centimeters.
