3 Stock Tank Heating Options for Your Home

A stock tank is a large water container that holds fresh or treated water for livestock such as cattle, horses, and pigs. It is typically made of galvanized steel and comes in various sizes ranging from small (20 gallons) to very large (500 gallons). The main purpose of the stock tank is to provide clean drinking water for animals on farms and ranches.

In order to keep the water inside the tank at an ideal temperature, especially during winter months, many people use tank heaters. Heaters come in three main types—electric, propane, and heat exchangers—and each has its own advantages and disadvantages. This blog post will discuss the different types of stock tank heaters available, tips to consider when buying one, DIY installation advice, maintenance suggestions, safety precautions, and the benefits of having a heater installed in your stock tank.

Electric Tank Heaters

Electric tank heaters are powered by electricity and require a standard 110-volt outlet for operation. They usually have an adjustable thermostat so you can set it to maintain a certain temperature range, keeping the water within safe levels. These types of heaters also come with thermal protection features that automatically shut off the unit if it begins to overheat. Electric tank heaters tend to be more expensive than other models but they are easier to install and don’t need to be refilled like some others.

Propane Tank Heaters

Propane tank heaters run on liquid propane gas and do not require electricity to operate. They are cheaper than electric heaters and can be used in areas where there isn’t access to power sources. However, they do require frequent refilling which can be costly and time consuming. Like electric tank heaters, these units feature adjustable thermostats and safety cutoffs so they won’t become too hot.

Heat Exchangers

Heat exchangers are devices that take energy from one source and transfer it to another without direct contact between them. In this case, the heat exchanger takes energy from the air outside and transfers it into the water inside the tank. These devices are efficient since they don’t use any fuel or electricity and can save you money in the long run. They require less maintenance than electric or propane heaters and are great for remote locations or places with limited access to utilities.

Tips To Consider When Buying A Stock Tank Heater

When selecting a stock tank heater, you should consider factors such as size, capacity, cost, efficiency, safety features, type of fuel/energy needed, and ease of installation. You should also make sure that the model you choose is suitable for the size and volume of your tank so it doesn’t overload the system or cause damage to the heater itself.

DIY Tank Heater Installation

Installing a stock tank heater is relatively simple, though it may vary depending on the type of heater you choose. Generally speaking, all that is required is connecting the electrical wires (if using an electric heater), mounting the unit onto the side of the tank, attaching hoses (if using a propane heater), and securing it in place with screws or brackets. For heat exchangers, you’ll just need to connect the hoses to both sides of the exchanger and secure it properly.

Maintaining Your Tank Heater

To ensure proper functioning and longevity of your stock tank heater, regular maintenance is recommended. Depending on the type of heater you choose, this could include changing filters, checking electrical connections, cleaning vents, replacing gaskets, or inspecting hoses for leaks. Regularly inspecting and maintaining your heater can help prevent problems before they occur and maximize its lifespan.

Advantages Of Having A Stock Tank Heater

Having a stock tank heater installed in your tank can offer several benefits. By providing consistent warmth throughout colder months, it prevents freezing temperatures that can put strain on pumps and pipes while ensuring your livestock always has access to clean drinking water. Additionally, installing a heater can reduce energy costs associated with heating tanks manually.

Safety Precautions For Using A Stock Tank Heater

Although generally safe to use when installed correctly, stock tank heaters still pose potential risks such as fire hazards due to improper wiring or faulty components. Make sure to follow instructions closely when installing and never leave your heater unattended while operating. It’s also important to inspect your heater regularly for signs of wear or malfunctioning parts.


Stock tank heaters are essential pieces of equipment for anyone who owns livestock as they provide clean drinking water year round no matter how cold it gets outside. With a variety of options available including electric, propane, and heat exchangers, there’s something for every budget and setup. Just remember to take safety precautions seriously whenever using a stock tank heater and follow manufacturer guidelines carefully when installing and maintaining it.
