How to Calculate the Size of Pool Propane Heater

Easy Steps to Determine the Perfect Size for Your Pool Propane Heater

If you have a pool and want to extend your swimming season, a propane heater is a great option. However, it's important to choose the right size heater for your pool to ensure optimal performance and efficiency. Here are the steps to calculate the size of pool propane heater you need:

Step 1: Determine the pool size
The first step is to determine the size of your pool. Measure the length, width, and depth of your pool in feet. Multiply these three numbers together to get the total volume of your pool in cubic feet.

Step 2: Calculate the required BTUs
BTUs (British Thermal Units) are a measure of heat energy. To calculate the required BTUs for your pool, you need to consider the following factors:

- Desired temperature: Determine the desired temperature for your pool. This will depend on your personal preference, but a common temperature range is between 78-82°F.
- Average temperature: Calculate the average temperature of your location during the swimming season. You can find this information online or by contacting your local weather service.
- Heat loss: Calculate the heat loss from your pool due to factors such as wind, humidity, and evaporation. This will depend on your location and the type of pool you have.

Once you have these factors, you can use the following formula to calculate the required BTUs:

BTUs = pool volume x temperature rise x 12

Temperature rise is the difference between the desired temperature and the average temperature. Multiply this by 12 to convert the result into BTUs per hour.

Step 3: Choose the right size heater
Once you have calculated the required BTUs, you can choose the right size heater for your pool. Propane heaters are available in different sizes, ranging from 100,000 to 400,000 BTUs. Choose a heater that is slightly larger than the required BTUs to ensure optimal performance and efficiency.

In conclusion, calculating the size of pool propane heater requires determining the pool size, calculating the required BTUs based on factors such as desired temperature, average temperature, and heat loss, and choosing the right size heater. By following these steps, you can enjoy a comfortable swimming season and extend the use of your pool.
