All-Pro propane heaters are portable combustion heaters that use liquid propane gas as a fuel. The company makes several models, ranging from convection models to forced-air and infrared radiant heaters. Propane heaters should only be used in garages or other areas with adequate ventilation and should not be used indoors.
When a fossil fuel burns completely, the only byproducts are carbon dioxide and water. However, fossil fuels are rarely able to achieve complete combustion, often leaving behind toxic byproducts, such as carbon monoxide. Carbon monoxide can displace oxygen in a room, leading to suffocation and death. For this reason, propane heaters are only suitable for outdoor use or in structures that possess a vent to the outside of at least 3 square feet in area.
All-Pro heaters range from 10,000 to 200,000 BTUs of heat, depending on the model. This output can present a fire hazard, so flammable items should be kept at least 4 feet away from the back and sides of these heaters and at least 10 feet away from the front heating element on forced air or infrared models. Extra propane cylinders should be stored away from an operating heater to reduce the risk of fire and explosion.
