How to Calculate Natural Gas Pool Heater Cost

Calculate Your Natural Gas Pool Heater Cost with These Simple Steps

If you're considering installing a natural gas pool heater, one of the most important factors to consider is the cost. Calculating the cost of a natural gas pool heater can be a bit tricky, but it's essential to ensure that you're getting the best value for your money. In this article, we'll guide you through the steps involved in calculating the cost of a natural gas pool heater.

Step 1: Determine the size of your pool
The size of your pool is the first factor to consider when calculating the cost of a natural gas pool heater. The larger your pool, the more energy your heater will need to produce to heat the water. Measure the length, width, and depth of your pool to determine its volume in cubic feet.

Step 2: Determine the desired temperature of your pool
The desired temperature of your pool is the second factor to consider when calculating the cost of a natural gas pool heater. The higher the temperature, the more energy your heater will need to produce to maintain that temperature. Determine the desired temperature of your pool in degrees Fahrenheit.

Step 3: Determine the efficiency rating of the heater
The efficiency rating of the heater is the third factor to consider when calculating the cost of a natural gas pool heater. The higher the efficiency rating, the less energy the heater will need to produce to heat the water. Look for the Annual Fuel Utilization Efficiency (AFUE) rating, which measures the percentage of energy that is converted into heat.

Step 4: Determine the cost of natural gas in your area
The cost of natural gas in your area is the fourth factor to consider when calculating the cost of a natural gas pool heater. The cost of natural gas varies depending on your location, so it's important to research the cost in your area. Contact your local natural gas company to determine the cost per therm.

Step 5: Calculate the cost of heating your pool
Now that you have all the necessary information, you can calculate the cost of heating your pool. Use the following formula:

Pool volume x 8.3 x (desired temperature - average temperature) x heater efficiency rating x cost of natural gas = cost to heat your pool

For example, let's say you have a 20,000-gallon pool, and you want to heat it to 80 degrees Fahrenheit. The average temperature of your area is 60 degrees Fahrenheit, and your heater has an efficiency rating of 80%. The cost of natural gas in your area is $1.00 per therm. Using the formula above, the cost to heat your pool would be:

20,000 x 8.3 x (80 - 60) x 0.80 x $1.00 = $6,640

Step 6: Consider additional costs
In addition to the cost of heating your pool, there may be additional costs to consider, such as installation, maintenance, and repairs. Be sure to factor these costs into your overall budget.

In conclusion, calculating the cost of a natural gas pool heater requires careful consideration of several factors, including the size of your pool, the desired temperature, the efficiency rating of the heater, and the cost of natural gas in your area. By following the steps outlined above, you can determine the cost to heat your pool and make an informed decision about whether a natural gas pool heater is the right choice for you.
