  2. Kerosene heater - Wikipedia

    en.wikipedia.org/wiki/Kerosene_heater

    When filling a kerosene heater, there is an opportunity for the fuel to vaporize and create an odour in the air. This is why it is important to fill the heater in a garage or outdoors. When a kerosene heater is first ignited, it takes a few seconds to a few minutes for the fuel to mix with the air in the perfect ratio for complete combustion.

  3. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    Larger tubes permit a slower airflow, which also yields more efficient energy transfer and permits much higher volumes to be transferred, permitting more air exchanges in a shorter time period, when, for example, you want to clear the building of objectionable odors or smoke but suffer from poorer heat transfer from the pipe wall to the air due ...

  4. Space heater - Wikipedia

    en.wikipedia.org/wiki/Space_heater

    Keeping flammable materials, such as paper, plastics, curtains, furniture, and bedding, at least 3 feet (0.91 m) away from the heater. Turning off the heater when the last adult leaves the room or goes to sleep and keeping children and pets three feet away from the heater. Placing heaters on a flat, hard, nonflammable surface.

  5. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.

  6. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    The conversion factor is 3.41 BTU/hr/watt. Since a heat pump moves three to five times more heat energy than the electric energy it consumes, the total energy output is much greater than the electrical input. This results in net thermal efficiencies greater than 300% as compared to radiant electric heat being 100% efficient.

  7. Radiant heating and cooling - Wikipedia

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Radiant heating as a technology is more narrowly defined. It is the method of intentionally using the principles of radiant heat to transfer radiant energy from an emitting heat source to an object. Designs with radiant heating are seen as replacements for conventional convection heating as well as a way of supplying confined outdoor heating.

  8. Heating system - Wikipedia

    en.wikipedia.org/wiki/Heating_system

    The main source of harmful greenhouse gas emissions is the type of heating systems being used. For example; central heating systems depending on what they use to burn/electricity consumed to heat the system. Another environmental impact is during winter months heating systems depend heavily more on fossil fuel based energy production. [11]

  9. Fan heater - Wikipedia

    en.wikipedia.org/wiki/Fan_heater

    A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any fan, create a degree ...
