A portable furnace is a small heater that is used to heat the air, usually in a specific indoor zone. Portable furnaces are a good choice for localized warmth at a very low fuel cost. A portable heater can be a cozy companion in a cold room, especially when only one area needs warming. That is why they are also called zone heaters or space heaters. Electric space heaters do not lose any energy through ducts or combustion. So they’re considered to be 100% efficient. All of the warmth generated by the space heater will radiate into the room.

A portable heater is specifically made to warm the nearby air and objects. They can be quite efficient in a confined space. The smallest ones can be tucked under a desk at work, keeping the heat fairly well confined to one user. The larger ones can be used to heat a chilly bedroom or children’s play area.

A few of the more expensive portable furnaces can come fully loaded with some pretty sophisticated features. Some models have LED readouts and programmable thermostats. If the heater accidentally tips over, a safety switch shuts it off immediately. Another great feature is the ability to adjust the thermostat with a remote control. This feature provides the ultimate portable furnace luxury: turning up the heat on a chilly morning without leaving the comfort of a warm bed.
