# How many BTUs do I need for a 15000 gallon pool?

The amount of BTUs needed to heat a 15000 gallon pool will vary depending on the temperature outside and how warm you want the water of the pool to be. Generally, it takes about 115 BTUs for every 1 degree Fahrenheit that you want to raise the temperature of the pool.

For example, if you want to raise the temperature of a 15000 gallon pool from 65 degrees Fahrenheit to 75 degrees Fahrenheit, that would be 10 degrees of rise, which would require 1150 BTUs. That is the answer on average, but with weather and seasonal changes, you may need more or less BTUs to get the desired temperature.

## How many BTUs does a gas pool heater use?

The exact amount of BTUs a gas pool heater uses depends on several factors, such as the size of the pool, the temperature of the pool water, the desired temperature of the pool water and the make and model of the gas heater.

Generally speaking, gas pool heaters range between 150,000 to 400,000 BTUs. A 400,000 BTU heater could raise a 26,000-gallon pool by 20 degrees in less than one day. The size of the heater necessary is calculated by the following formula: gallons of water multiplied by 8.

34 (pounds per gallon) multiplied by the temperature rise desired and then divided by the efficiency of the heater (82-84%). For example, a 26,000-gallon pool with a desired temperature rise of 20°F requires a heater of 400,000 BTU.

## How do I know what size gas pool heater I need?

When selecting a gas pool heater for your pool, you need to take into account the size and volume of your pool, as well as your desired pool temperature. To accurately determine the size of your pool and its volume, you will need to measure the length and width of each length segment, and then the average depth from the shallowest to the deepest spot of your pool.

Use these measurements to calculate your pool’s volume, by multiplying these numbers together.

Once you have your pool’s volume, it’s time to figure out the size of pool heater you need. Generally, one BTU (British Thermal Unit) is needed to increase one gallon of water by 1° Fahrenheit each hour.

One BTU is equivalent to approximately 25 watts. To determine the size of pool heater you need, take the volume of your pool (in gallons) and multiply it by 8. Then take that number and divide it by 24, 36, or 45 (depending on what temperature you want your pool to be raised an hour).

This number you get is the BTU size you need for your pool heater.

As an example, suppose you have a 20,000-gallon pool, and you want to heat your pool by 10° Fahrenheit per hour. In this case, you would need to calculate 20,000 x 8 = 160,000. Next, divide this number by 24 (for a 10° Fahrenheit increase) and you get 6,666.

This means that a pool heater of 6,666 BTUs is the size you need to raise the temperature of your pool by 10° Fahrenheit per hour.

After you have determined the BTU size you need for your pool heater, you should also ensure the size of your gas line and gas meter can handle the size of the pool heater you have selected. Be sure to consult an expert or local store for help and advice when it comes to selecting and installing a pool heater.
