Salt begins to melt at 800°C (1,472° F) and is perfect as a heat storage medium. As soon as the SALT VITALHEATER is placed into operation the radiant heat of the infrared heating lamps is immediately noticeable. When the salt brick has warmed-up after a half an hour a thermal storing mass is created which continuously radiates heat throughout the surrounding area. The average temperature of the salt brick is reached at 95°C (203° F) in a fully heated room. Even if the heating lamps are dimmed, a large part of the heating radiation is retained.* The watt strength of the infrared heating lamps (300-2000 W) is significantly lower than that of conventional electric heaters. For the first time this makes electrical heating as an economically affordable option.* (See the Vienna Displacement Law)
The Vienna law states on the one hand: If the wattage, i.e. the power consumption or current consumption is reduced from an infrared heat source then its heat radiation is reduced to a lesser extent than one would expect from the light intensity reduction. Although the brightness changes, the intensity of infrared heat radiation is only slightly reduced due to the so-called shift of the radiation maximum.*
