I have a 150 Gallon stock tank. I thought I would try this design. Barely got below freezing and the water had slush in it. Our winter temps get down to around -10 come January. I will NOT be buying this style deicer again.
This water heater has saved me so much time and made our horses and donkeys very happy. They always have water and we both dont have to fight with ice.
