There is a likelihood that underfloor heating may add to offgassing and sick building syndrome in an environment, particularly when the carpet is used as flooring. [citation needed] Electric underfloor heating systems cause low frequency magnetic fields (in the 50–60 Hz range), old 1-wire systems much more so than modern 2-wire systems.
A heating film, itself, is a variation of the modern ondol, but it doesn't require hot water and pipes as it is fully electric. There are also many variations of this underfloor heating system, as many underfloor heaters are based on PTC heating element, far-infrared rays, carbon film, or cables, etc. [6]
Economically, electric heat can be compared to other sources of home heating by multiplying the local cost per kilowatt hour for electricity by the number of kilowatts the heater uses. E.g.: 1500-watt heater at 12 cents per kilowatt hour 1.5×12=18 cents per hour. [14]
Underfloor heating systems—electric or hydronic; 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 ...
Electric heating or resistance heating converts electricity directly to heat. Electric heat is often more expensive than heat produced by combustion appliances like natural gas, propane, and oil. Electric resistance heat can be provided by baseboard heaters, space heaters, radiant heaters, furnaces, wall heaters, or thermal storage systems.
The heat transfer coefficient has SI units in watts per square meter per kelvin (W/(m 2 K)). The overall heat transfer rate for combined modes is usually expressed in terms of an overall conductance or heat transfer coefficient, U. In that case, the heat transfer rate is: ˙ = where (in SI units):
