DIRECTTECH Stone®

Top-quality marble and granite have the natural ability to convert conducted energy into long-waving infrared radiation. This ability of heat radiation was already realized in ancient times. DIRECTTECH STONE® products combine most modern infrared heating technique with this knowledge. This way, a comfortable indoor temperature arises. The low energy use preserves the environment and your finances.

Design and function

DIRECTTECH STONE® heating panels are designated to be used as a wall- or stand element. The design with insulation on the back side and the stainless steel covering provides highest heat emission. The panels can be very easily installed, horizontal as well as vertical.

Highest efficiency

An installation below the height of 1,80 m requires a maximum surface temperature of 100 °C according to the standard DIN EN 60335. This is reached through activating the safety switch „Limiter”, that takes place at an inside temperature of 100 °C. The Installation above the height of 1,80 m allows higher temperatures, so that the entire efficiency of the long-waving infrared radiation can be utilized, that takes place at a temperature of 120 °C.

Safety factor

Is the defined maximum temperature reached by the heating technique in the interior system, the internal safety switch “Limiter” is activated and the temperature is reduced. The maximum operating temperature is below the cut-off safety temperature and can vary due to environmental conditions, e.g. supply voltage, ambient (room) temperature and environmental humidity.
