2. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   Wall heating systems; Radiant ceiling panels; Underfloor and wall heating systems often are called low-temperature systems. Since their heating surface is much larger than other systems, a much lower temperature is required to achieve the same level of heat transfer. This provides an improved room climate with healthier humidity levels.

3. 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 ...

   Industrial water heaters may reach 2000 kilowatts. Where off-peak electric power rates are available, hot water may be stored to use when required. Electric shower and tankless heaters also use an immersion heater (shielded or naked) that is turned on with the flow of water. A group of separate heaters can be switched to offer different heating ...

   Avoiding the use of heaters near flammable materials such as paint or gasoline. Installing smoke alarms and carbon monoxide detectors nearby. The risk of fire (and burns) is sometimes less with oil-filled heaters than those with fans, [8] [9] but some fan-assisted heaters have a lower risk of fire (and burns) than other oil-filled heaters. [10]

6. 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.
