  2. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    Economically, electric heat can be compared to other sources of home heating by multiplying the local cost per kilowatt hour for electricity by the number of kilowatts the heater uses. E.g.: 1500-watt heater at 12 cents per kilowatt hour 1.5×12=18 cents per hour. [18]

  3. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    90–95% (multiply by the energy efficiency of electricity generation to compare with other water-heating systems) Electric heater: Electrical to thermal ~100% (essentially all energy is converted into heat, multiply by the energy efficiency of electricity generation to compare with other heating systems) Others: Firearm: Chemical to kinetic

  4. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    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. Electric heaters are usually part of a fan coil which is part of a central air ...

    en.wikipedia.org/wiki/Space_heater

    In the United States, Underwriters Laboratories' UL 1278 [11] (for portable electric space heaters) and UL 1042 [12] standards (for portable and fixed baseboard electric heaters) certify heater safety. Although the General Services Administration had Specification W-H-193 [13] for

  8. Radiator (heating) - Wikipedia

    en.wikipedia.org/wiki/Radiator_(heating)

    A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.

  9. Convection heater - Wikipedia

    en.wikipedia.org/wiki/Convection_heater

    A convection heater, also known as a convector heater, is a type of heater that utilizes convection currents [1] to heat and circulate air. These currents move through the appliance and across its heating element, [ 2 ] using thermal conduction [ 3 ] to warm the air and decrease its density relative to colder air, causing it to rise.
