2. Infrared heater - Wikipedia

   en.wikipedia.org/wiki/Infrared_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.

3. Infrared lamp - Wikipedia

   en.wikipedia.org/wiki/Infrared_lamp

   The development of quartz halogen linear lamps allowed much higher power density up to 200 watts/inch of lamp (8 w/mm), useful for industrial heating, drying and processing applications. [3] By adjusting the voltage applied to incandescent lamps, the spectrum of the radiated energy can be made to reduce visible light and emphasize infrared ...

4. Passive daytime radiative cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_daytime_radiative...

   [34] [35] PDRC can be contrasted with traditional compression-based cooling systems (e.g., air conditioners) that consume substantial amounts of energy, have a net heating effect (heating the outdoors more than cooling the indoors), require ready access to electric power and often employ coolants that deplete the ozone or have a strong ...

5. Gas heater - Wikipedia

   en.wikipedia.org/wiki/Gas_heater

   Upright non-flued liquefied petroleum gas heater, 1970s A wall mounted gas heater that runs on either propane or natural gas. A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or ...

6. Phase-out of incandescent light bulbs - Wikipedia

   en.wikipedia.org/wiki/Phase-out_of_incandescent...

   Incandescent light bulbs that meet the new standards, for example high-efficiency halogen bulbs, would continue to be available. [111] It is estimated that greenhouse gas emissions will be cut by 800,000 tonnes (Australia's current emission total is 564.7 million tonnes), a saving of approximately 0.14%. [112]

7. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   Electric heating can either be purely resistance-type heating or make use of a heat pump system to take advantage of low-grade heat in the air or ground. A district heating system uses centrally located boilers or water heaters and circulates heat energy to individual customers by circulating hot water or steam. This has the advantage of a ...
