The design radiator is available with water, current or in the combination water as well as current. Those are two completely different systems; that means that during the operation with current, the water in the model is not heated but the ceramics is heated by means of specific heating mats and/or heating foils. In case the system is operated with water, the design radiator is connected to the central heating systems and heats depending on the supply temperature of your heating system. In case of a desired surface temperature of the design radiator of 45 ° C the supply temperature should amount to approx. 60 ° C. The time until this surface temperature is reached amounts to approx. 40 minutes. Please always make sure to provide for an own heating circuit for the operation. It is possible to control via a so-called flush-mounted thermostat or directly via the heating manifold by means of an actuator with room temperature controller. Es In case of operation with current, the heating-up time amounts to approx. 30 minutes. This is primarily due to the fact that the heating mats used by us are directly mounted at the bottom side of the ceramics.
