2. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   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 conditioner. They circulate heat by blowing air across the heating element which is supplied to the furnace through ...

3. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   Air-to-air heat pumps provide hot or cold air directly to rooms, but do not usually provide hot water. Air-to-water heat pumps use radiators or underfloor heating to heat a whole house and are often also used to provide domestic hot water. An ASHP can typically gain 4 kWh thermal energy from 1 kWh electric energy.

7. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right ...
