2. Infrared heater - Wikipedia

   en.wikipedia.org/wiki/Infrared_heater

   A household infrared electric heater. An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or ...

   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. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...

6. 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 ...

7. Oil heater - Wikipedia

   en.wikipedia.org/wiki/Oil_heater

   A 500-watt heater will take at least twice as long to reach the same thermostat setting as a 1000-watt unit; however, the total electricity consumption will be the same for both. Additionally, the rate of heat flow from a heater to the air directly in contact with it is higher when there is a greater temperature difference between the two.
