Electricity is used in some space heaters directly to create heat by resistance. Electric current is passed thru a coiled wire or long metal ribbon made of a metal with a high resistance. Resistance is to electricity as friction is to movement. Rub your hands together, and they heat up from friction. In a similar way, as electri ity is resisted by the wire or ribbon, the metal heats up, and then radiates into the surrounding air.

An electric water heater, also called an immersion heater, is an insulated and waterproofed heating element that consists of the right amount of resistance wire to draw the required power on the given house supply.

The heating element is immersed in the water so that the heat it produces will raise the temperature of the water.

For example a 3 kW water heater for a 240 v supply would have a resistance of 31.7 ohms.

How is resistance used in a space heater?

In an electrical space heater, electrical current dissipates energy into heat, and the heat radiates from the element. In a fuel powered space heater, an orifice throttles the fuel feed (resistance to flow), which controls the heating rate. In a steam powered space heater, an orifice throttles the steam (resistance to flow), which controls the heating rate.

Can a pellet stove be used without electricity?

No, electricity is required to run the motors for the augers and blowers to feed pelets into the burn pot and to circulate the air (for combustion and possibly a second blower for the room air). While electricity is required, most pellet stoves only use a few hundred watts (using the most when the igniter is on) compared to a thousand watts for a small space heater. This means that if you are running off a generator and have limited power available, pellet stoves provide a substantial amount of heat compared to a small space heater.
