How to Keep Water Tanks from Freezing

If you’ve ever had a water storage tank freeze, then you know just how much of a disaster it can be. As the colder months are fast approaching, now is the time to consider what you can do to keep your tanks protected from failure.

When it comes to freeze protection for water storage, the water itself is only half the equation. Surely it’s obvious that your priority would be to protect your storage from freezing, but have you stopped to consider that your storage tank needs just as much protecting? If you’ve stored water before in cold temperatures, then you probably have, because you’ll be well aware of water’s unique characteristics.

Of all the pure elements on earth that we know of, H₂O is the only molecule that expands when it freezes. Everything else contracts. With this being the case, one can imagine, and most of us have experienced firsthand, the dilemma posed by water’s frozen state. As it has to do with tank storage, well, potential damage to the tank is a very real concern. Consequently, having your water storage tank freeze can create a very big problem.

Most water storage tanks are equipped with two different types of systems for churning the water within the tank. These systems only work well within the proper environments, however. One such system is known as a passive system. These are hydrodynamic mixing systems. Another type is a jet aeration system. Jet aeration systems create movement in the water only during the filling process, which means that are completely incapable of preventing ice buildup in the tank once the temperature drops.

Then there are your active systems, and there are two kinds: pulse hydraulics and solar. These types of systems are known as active because they can be programmed to respond to various needs in the tank environment. However, only the most powerful active mixers can prevent ice buildup all winter long.

So here’s the moral of the story: unless your environment is just right, simply moving the water around in your tank isn’t going to prevent freezing. Even if you have a large and powerful active mixer, you’re still gambling with Mother Nature. When ice develops in your water storage, it can damage your controls, the interior of the tank, or it can even puncture the walls of your tank. What’s more, all this can happen before you even realize you have ice buildup.

 

The Answer

So how to keep water tanks from freezing, it’s a good question. But as you can already tell, the answer section to this topic is much shorter than the problem, and that’s because the solution is simple. In order to eliminate the damage associated with freezing water, you simply have to keep your tank at the ideal temperature. To be quite frank, the traditional methods for reducing ice formation inside water tanks are expensive, difficult, and only partially effective, hence the word “reducing” instead of “eliminating”.

So when seeking a solution for preventing ice buildup inside a storage tank, the most important thing to remember is uniformed heat. In order to properly prevent ice buildup, you need to maintain the same temperature at the bottom of your water tank, as you do at the top. In order to do this, you need to have a solution in place that can keep your tank at an ideal, regulated temperature year round. And thankfully, it just so happens that we provide that very solution here at Powerblanket.

Powerblanket's custom tank heaters provide freeze protection, making your business more sustainable and efficient.

  1. I use an engine block heater on my travel trailer. The water flows slowly from tank drain thru the blick heater then into a condensate pump which sends it back into tank. Tested at 15 degrees for two days
    Works great.

  5. I want to keep my 10000 lts. Tank warm in wi ters when the temp. Is around 5 degrees during night. If i use the powerblanket what will be the difference in the water temp. Its a 10000 ltrs round shape 3 feet in height tank.
