2. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   The power through the thermostat is provided by the heating device and may range from millivolts to 240 volts in common North American construction, and is used to control the heating system either directly (electric baseboard heaters and some electric furnaces) or indirectly (all gas, oil and forced hot water systems).

3. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. [1]

4. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   A heating system is a mechanism designed to regulate and maintain a desired temperature within a space by utilizing thermal energy. It is a fundamental component of Heating, Ventilation, and Air Conditioning (HVAC) systems, providing warmth to residential, commercial, and industrial buildings.

5. 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 ...

6. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   Electric point-of-use (POU) tankless water heater, wall-mounted under a sink (Germany) Tankless water heaters can be further divided into two categories according to their heating capability: "full on/full off" versus "modulated". Full on/full off units do not have a variable power output level; the unit is either fully on or completely off ...

7. Space heater - Wikipedia

   en.wikipedia.org/wiki/Space_heater

   These heaters are often designed such that the frequency of the emitted waves are in the infrared part of the electromagnetic spectrum. The materials used in radiant heaters can vary. Halogen heaters have tungsten filaments in sealed quartz envelopes, mounted in front of a metal reflector in a plastic case. They operate at a higher temperature ...
