Measurement of the electromagnetic fields emitted by Fenix products
Interest in electric heating systems is increasing constantly, particularly in connection with those that utilize large surface areas (floor and ceiling heating systems). The growing demand is also accompanied by an increasing amount of questions from customers regarding the potential health risks connected with long-term exposure to what is known as electromagnetic smog.
In response to these queries, Fenix asked for a test to be carried out focused on determining the exact electromagnetic field emission values of items in our product range. The measurements were carried out by the Electrotechnical Testing Institute, s.p. in Prague-Trója. The tested products were a single-core heating cable with protective braiding (PSV 10W/m), a two-core heating cable with protective braiding assembled into a mat (LDTS 160/1), an ECOFILM F 1008 heating foil, and the radiant panels ECOSUN 600U (the heating element is a foil) and 700U (the heating element is a resistance wire cable).
The electromagnetic compatibility of each of the products was tested, their disturbance voltages and disturbance powers were measured with regard to the power grid frequency, and primarily the intensity of the electromagnetic field was measured with respect to human exposure. The measurements were carried out in accordance with European technical standards EN 62233 and EN 55014-1, which are the only valid EU regulations defining the exact methods and measuring devices to be used in testing, as well as the permitted limits.
The obtained results show that all of the determined values lie well below the limits set by the valid standards (see the enclosed protocols). It is interesting, for example, that the results for the single-core and two-core heating cables are almost identical; there is a deep-rooted belief that single-core cables are many times worse than two-core cables with regard to so-called electromagnetic smog.
The highest electromagnetic field values were measured for the ECOSUN 600 U radiant panel, but even in this case they only amounted to 2.2% of the permitted limit. It is thus clear from the measurement results that individuals who install electric heating systems in living areas are in no way exposing themselves to an intensive electromagnetic field that could give rise to health risks.
