How do you keep a water storage tank from freezing?
To keep your water storage tank from freezing, make sure it is properly insulated in the winter, placed in a location like a barn or shed or garage, and consider installing an aeration pump to keep the tank’s water circulating. If you have an outdoor water storage tank in a part of the country prone to frigid temperatures, you will need to take precautions to keep your water from freezing over. Moving the tank to an indoor location, like a shed, will provide it from direct exposure to extreme temperatures. Placing an insulated cover over the tank will trap heat within the tank and prevent the water from chilling too fast. Perhaps the best way to ensure that your water stays in liquid form is to keep the water in perpetual circulation. Standing water freezes much quicker than moving water, so the addition of an aeration pump to the tank will keep the water in motion.
You can also always upgrade to a larger tank. The larger your atmospheric tank’s reservoir of water is, the longer it will be able to withstand freezing temperatures. Round tanks are also less likely to freeze compared to rectangular tanks, as they have less surface area and therefore emit less heat. Heated barrel or drum heaters can be wrapped around tanks and distribute uniform heat throughout the water storage tank.
