You will find that propane heaters come in several varieties. Propane furnaces have a fire box and force air that has been heated into the rest of the home. Propane fireplace logs, offer better heat than wood logs as the flue can be closed and the heat kept in the home. A freestanding efficient propane heater offers radiant heat that can quickly warm a room and keep it warm with low amounts of propane being used. An electric heater would probably be more convenient to use indoors than lugging around a big propane heater, but there are also other factors to consider. If propane is less expensive where you live than electricity, then the inconvenience of a propane heater may prove to be worth the hassle.
