How to Heat a Stock Tank Pool? 

Now that you know how to make a stock tank pool, you can customize it however you like. Heating a stock tank pool converts it into a hot tub on the go. Just keep in mind that, like making one, you will need some handiness to heat a stock tank pool. 

Prepare the Pool Parts

From what we have researched, using an outdoor propane hot water heater and mounting it to the side of your home or a sturdy fence is the most efficient method to heat your stock tank pool. 

An alternative would be to use either an electric heater or a spa heater, but the materials needed to connect the parts together may vary. Either way, you would need some sort of heating mechanism to connect to your stock tank pool. 

Typically, you would need the following components: 

  • Water heater
  • Water circulation pump
  • Water spigot/fittings
  • PVC tubing
  • Swimline adapter
  • Sealant

For this DIY project, you will need the following tools:

  • Hole saw
  • Screwdriver
  • Pliers
  • Cordless drill
  • Heavy-duty utility knife

Choose your Water Heater

By comparison, an in-ground pool heater using 400,000 BTUs will consume four gallons of propane per hour to heat a standard nearly 20,000-gallon pool. 

It will, however, require a much smaller propane water heater to heat a stock tank pool that only uses around 800 gallons of water.

You can expect to spend between $150 and $350 on an outdoor propane water heater for your stock tank pool. Price variations will depend on the temperature the water heater can reach and how long it may take to reach that temperature.

Consequently, getting the smaller propane water heater will be less expensive, but expect it to take two hours to raise the temperature of a standard stock tank by 10 degrees. A large option can heat up to 100 degrees in less than two hours.

Install the Parts

The installation of the necessary parts is fairly straightforward once you have all the necessary components.

  1. Install the propane water heater and pump on a sturdy wall or fence.
  2. Drill the holes for the necessary fittings.
  3. Connect the hoses to the water heater and pump.

Once everything’s installed, you can now proceed to heat your stock tank pool: 

  • Turn on the heater, with the water and gas set to maximum and the heating set to “full.” There may be an “eco” option depending on the brand that may burn more gas but will heat your pool faster.
  • Speed up the heating process by placing an insulating pool cover over the stock tank pool while it is heated.

After a couple of hours, depending on your heater’s power and the size of your pool, you are almost done! You can finally use your stock tank pool as a hot tub.

Quick Reminders

As you install your heater, consider getting an outdoor power strip to facilitate the connection of the necessary parts to electricity when necessary. It is never a good idea to use indoor power strips outdoors.

You might also want to insulate your stock tank pool while you’re at it. The use of proper insulation assists in maintaining a comfortable pool temperature and increases the pool’s thermal efficiency. 

You can insulate a stock tank with a simple DIY project, using carpet padding, foam board, or wrapping a thick decorative sleeve around the pool.

Final Thoughts

Stock tank pools are a great way to enhance the aesthetics of any barndominium, whether it is a naturalistic barndominium or a more modern barndominium.

The versatility of stock tank pools extends beyond aesthetics and extends to functionality. This allows you to upgrade it as you would a regular pool but at a lower cost and more energy efficiency.

Now that you know the steps on how to heat a stock tank pool go ahead and try it out! One of the great perks of owning a stock tank pool is that you can customize it to your liking, and you can transform it into a makeshift hot tub when you wish.
