<p>The method involves providing hybrid heating that takes place by cascading of heat sources, where the heat sources are connected and heated by a switchable electric heater using domestic heating technique. Warm air transportation is performed under utilization of gravitational force circulation, where the gravitational force circulation is supported by fans. Heating power of the electrical heat source is controlled by adjustable thermostats. Multiple heating elements (5) are arranged in a cascade manner. An independent claim is also included for a device for heating a sauna room, bio sauna room or steam bath.</p> |
