How To Care For An Immersion Heater Placed In A Large Water Tank

Construction & Contractors Articles

If your business uses large barrels of water to cool the products being made, it is likely that at least a portion of the water needs to be stored outside. While this is your best option to minimize spacial concerns within your plant or manufacturing building, the water outdoors may end up freezing if you do not take necessary precautions to prevent issues ahead of time. One of the best ways to prevent a freezing issue is to make sure that each barrel contains an immersion tank heater. These devices consist of a variety of anodes or rods that help to consistently heat the water so it does not freeze. However, if you do decide to utilize an immersion tank heater, then you will need to make sure that you take care of it properly with the following tips.

Remove Mineral Debris

If the water that fills your water tanks contains hard water, then it is likely that the calcium and magnesium in the water will adhere to your anodes over time. This issue is similar to one you may experience with your home water heater. However, your home system will have something called a sacrificial rod that will rust and deteriorate. Without the rod, the minerals in the water can cause the tank to deteriorate quite quickly. Your water tank will not have one of these rods though, and the heat from the immersion heater will allow minerals to dissolve and then solidify on the heater itself. The collection of these minerals will stop the steel, iron, copper, or titanium heater from working effectively. To keep the water in your tank from freezing when this happens, make sure to remove and clean the heater every few months. 

Unplug the heater unit first and then remove it from the top or side opening of the water tank. Fill a bucket with about one gallon of vinegar and one gallon of water. Place the heater in the bucket overnight and gently rinse it off. The vinegar should dissolve all of the mineral deposits. Afterwards, use a flashlight to peer inside your water tank. If the tank is covered with a layer of debris like the heater, then it will need to be flushed and rinsed with vinegar as well. Otherwise, the heater will collect the mineral deposits fairly quickly. You may also want to think about placing a small metal rod in the tank to keep rusting and general deterioration at bay. This will protect not only the tank but the metal of your heater as well. Look for a variety that is meant for placement in a water heater. Typically, the anodes are made from magnesium or aluminum with a steel core along the middle. 

Keep The Tank Filled

The immersion heater that you place in your water tanks will work by heating water near the anodes. As the water heats up, it circulates and cold water begins to move toward the heater. This water is then heated, and this process helps to keep all of the water in the tank at a consistent warm temperature. Most tank heaters will produce a relatively large amount of heat to keep the water warm and they will turn on and shut off automatically. You need to understand that the heaters are meant to remain inside fluid though, so that heat is consistently transferred away from the metal anodes. Without the transfer of heat, the heater can overheat quickly and burn out. 

To prevent a burnout issue, make sure that you monitor the volume of fluid within the tank. If tanks are large and you invest in a heater that screws into the top of the tank or sits along the side, then think about adding a bobber tank gauge like one used for large heating oil and gas tanks. You will need to create a small hole in the top of the tank. Place the bobber and metal rod through the hole and secure the gauge to the top of the tank. As the water level in the tank starts to drop, the bobber will fall and pull the gauge downward to provide an accurate reading of the volume of water in the container.

inspecting the roof on your home

When was the last time you really looked at your roof? I had no idea how important yearly inspections of my roof was until I found myself footing the bill for a full roof replacement and interior ceiling replacement. Since then, I have learned how to inspect my own roof twice each year. I always inspect it each spring after the harsh winter elements have gone away and again in the fall before winter weather sets in. You can use the information compiled on my website to inspect the roof on your home and make the small repairs that will save you from full roof replacement.
