2. Fan heater - Wikipedia

   en.wikipedia.org/wiki/Fan_heater

   Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any ...

3. Ceramic heater - Wikipedia

   en.wikipedia.org/wiki/Ceramic_heater

   A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.

4. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   Circulation heaters or "direct electric heat exchangers" (DEHE) use heating elements inserted into a "shell side" medium directly to provide the heating effect. All of the heat generated by the electric circulation heater is transferred into the medium, thus an electric heater is 100 percent efficient. Direct electric heat exchangers or ...

5. Self-regulating heater - Wikipedia

   en.wikipedia.org/wiki/Self-regulating_heater

   The heat output of any electrical heating element can be regulated by regulating the electrical power input. PTC heating elements also can be regulated indirectly. For example, a PTC heating element with a sharp change in resistance at a particular temperature can be fitted with a constant voltage source and a variable-speed fan.

6. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   Electric heating or resistance heating converts electricity directly to heat. Electric heat is often more expensive than heat produced by combustion appliances like natural gas, propane, and oil. Electric resistance heat can be provided by baseboard heaters, space heaters, radiant heaters, furnaces, wall heaters, or thermal storage systems.

7. Heating film - Wikipedia

   en.wikipedia.org/wiki/Heating_film

   The films can also be used in heating panels to produce wall or ceiling panel heaters. Although heating films do not usually run at very high temperatures (typically 30 °C (86 °F) on floors and up to 40 °C (104 °F) on walls), due to the large surface area they cover, they can provide significant energy output.
