They do not use fan or mechanical relays, so you can’t hear them operating or switching. The heaters also have a closed heating element - a child or pet will not be able to get burned, and dust or thread will not be able to get inside and catch fire, and there will be no unpleasant smell of burnt dust and no dry air.

The heaters have smart “brains” inside them, as well as an Android/iOs application with your mother tongue, which allows you to: control all heaters remotely, lower your utility bills or just set a convenient schedule and forget!
