An indoor propane heater is a heating system that uses propane gas as a fuel source and radiates heat through infrared waves. Propane heaters can provide heat quickly and evenly. They can be vented or vent-free and typically require a source of electricity to operate.
Some indoor radiant propane heaters do not require electricity to operate. These types of heaters are typically vent-free and are designed to be simple, efficient, and easy to use. They burn propane gas and radiate heat through infrared waves, eliminating the need for electricity.
However, it’s worth noting that most indoor propane heaters need a source of electricity to ignite the flame, and some also have a blower fan which also requires electricity.
It’s best to check with the manufacturer or consult the product manual to confirm whether a specific model requires electricity or not.
