When selecting an electric heater, you should pay attention to the control equipment and user comfort in addition to the visual look and heating power. Harvia heater models utilise three different control methods:
Fixed operating switches
External digital control panel
External control unit that takes care of the power input of the heater
The fixed, mechanical operating switches are placed on a side or at the top or the bottom of the heater.
If you wish to avoid bending down or your bench solution prevents manual access to the heater, you can select a heater model that is equipped with an external control panel or control unit. The external control panel can be installed in the dressing room, for example – it also shows the temperature of the sauna.
External control units are necessary for large heaters used in public facilities, but they are also well-suited for home use (consult your electrical engineer first).
