Many electronic patio heaters, fans, and even fire pits will come with a wall switch or control knob to allow for convenient adjustment of your item. These switches may come with the option of a weatherproof cover to protect your electronics from the elements.
If your switch will be installed in a protected area, such as under a pergola or permanent awning, you should be fine without a weatherproof cover. If there is no chance that the faceplate or switches will come in contact with rain or snow, a weatherproof cover is not necessary.
If your switch or control panel will be installed in an unprotected area that is open to the elements, you should make sure you purchase the options with a weatherproof cover to avoid water damage to your controls.
