2. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   Baseboard heaters will especially benefit from a programmable thermostat which is capable of continuous control (as are at least some Honeywell models), effectively controlling the heater like a lamp dimmer, and gradually increasing and decreasing heating to ensure an extremely constant room temperature (continuous control rather than relying ...

3. Self-regulating heater - Wikipedia

   en.wikipedia.org/wiki/Self-regulating_heater

   For example, space heaters use heating elements much hotter than the room being heated. In these applications, a thermostat may be better able to sense and control the temperature of the item being heated. Nevertheless, a self-regulating heating element may still be used to keep the heating element from damaging itself or other parts of the heater.

4. Thermostatic radiator valve - Wikipedia

   en.wikipedia.org/wiki/Thermostatic_radiator_valve

   A thermostatic radiator valve on position 2 (15–17 °C) Installed thermostatic radiator valve with the adjustment wheel removed A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.

5. Thermoelectric cooling - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_cooling

   Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

6. Stirling engine - Wikipedia

   en.wikipedia.org/wiki/Stirling_engine

   A 2-horsepower (1.5 kW) engine, built in 1818 for pumping water at an Ayrshire quarry, continued to work for some time until a careless attendant allowed the heater to overheat. This experiment proved to the inventor that, owing to the low working pressure obtainable, the engine could only be adapted to low power for which there was, at that ...

7. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   Newer versions of this type of control do not use a choke as such, but much smaller capacitors and/or solid-state circuitry; the switch is typically mounted in a standard in-wall gang box. The old one is called electrical fan regulator that works on the principle of reducing voltage and the new one is called electronic fan regulator that works ...
