Self-reliance and sustainability in the 21st century.
Most stock tanks aren’t designed to maintain the temperature of the water, which would slow freezing. The tanks have no insulation, and the large area of water exposed to air doesn’t help either. So, most of the time, people drop a floating electric tank heater into the water, plug it in and pay the electric bill. But there’s a better (and less expensive) solution — solar livestock water tanks.
You can Build a Solar Stock Tank for about $300, and it should keep your stock tank water ice-free in all but the worst winter weather. Even if you still need to use an electric heater, the solar stock tank will reduce your electricity usage in winter.
If you’re not a do-it-yourselfer, you can buy solar livestock waterers, too. Or register to win a 25-gallon, solar water trough from eNasco. It prevents water from freezing even in temperatures as low as 20 below zero.
