2. Self-regulating heater - Wikipedia

   en.wikipedia.org/wiki/Self-regulating_heater

   A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.

3. Heating element - Wikipedia

   en.wikipedia.org/wiki/Heating_element

   A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating. Heating elements are used in household appliances, industrial equipment, and scientific ...

4. 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 .

5. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   This is due to the modern design features that are added during manufacturing. Alongside new designs the use of a thermostat or sensor has improved the efficiency of the storage heater. A thermostat or sensor is able to read the temperature of the room, and change the output of the heater accordingly. Water can also be used as a heat-storage ...

6. 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.

7. 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.
