NOTE: The heating element may not feel warm to the touch when submerged, this is NOT an indicator of whether it is working. Always keep the heating element free from mineral build-up. Also, natural dissolved gases in your water can create foam in or around the deicer due to the temperature change, this is normal and is not toxic, it is natural.
