2. Fan heater - Wikipedia

   en.wikipedia.org/wiki/Fan_heater

   Electric 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 ...

3. Dehumidifier - Wikipedia

   en.wikipedia.org/wiki/Dehumidifier

   The dehumidification process is the inverse of adding water to the room with an evaporative cooler, and instead releases heat. Therefore, an in-room dehumidifier will always warm the room and reduce the relative humidity indirectly, as well as reducing the humidity more directly, by condensing and removing water.

4. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

5. Thermal destratification - Wikipedia

   en.wikipedia.org/wiki/Thermal_destratification

   When used in the summer to encourage evaporative cooling, HVLS fans are run forward, blowing air at the floor. When used for destratification in the winter, the fans are run in reverse, blowing air towards ceiling which then circulates around the room. The height at which HVLS fans can be effective is limited compared to axial destratification ...

6. Crawl space - Wikipedia

   en.wikipedia.org/wiki/Crawl_space

   A crawl space or crawlspace is an unoccupied, unfinished, narrow space within a building, between the ground and the first (or ground) floor. The crawl space is so named because there is typically only enough room to crawl rather than stand; anything larger than about 1 to 1.5 metres (3 ft 3 in to 4 ft 11 in) and beneath the ground floor would ...

7. Space heater - Wikipedia

   en.wikipedia.org/wiki/Space_heater

   Convective space heaters utilize convection to transfer heat from the power source to a space. These heaters typically either rely on natural or forced convection. Natural convection is a phenomenon where temperature variations in an environment generate fluid flow. Forced convection heaters utilize a device like a fan to generate air flow and ...
