How big of a pool heater do I need for a 15000 gallon pool?
How big of a pool heater do I need for a 15000 gallon pool?
For pools under 10,000 gallons, small gas heaters like the Hayward 100K$) BTU output are suitable. Pools up to 15,000 gallons should look at the Pentair 125K BTU or higher, and 20,000 gallon above ground pools should look at the Raypak 150K BTU.
How big of a pool heater do I need for a 15 x 30 pool?
This answer is the minimal BTU size recommended for that particular surface area. Continuing the example above with the 15 x 30 pool, after dividing by 3, you get 150. Therefore, the minimum size heater that is recommended for a 15 x 30 pool is 150,000 BTUs.
How do you determine the size of a pool heater?
When you are determining which size pool heater to buy, the first step is calculating your pool’s surface area. A lot of pool owners assume that you use your pool’s gallon size to determine your heater size. In fact, there are some websites that DO use the number of gallons.
How much heat should I add to my Pool?
Click calculate to get your Please note that heat rise varies when dealing with different heaters. The usual recommendation is an increase of 1 to 1 and a half degree per hour. Calculations are rough estimates as to which size pool heater you may need. Most newer heaters are at least 83% efficient.
Do you need to oversize a gas pool heater?
When it comes to gas heaters, you always want to oversize the unit. The job of a pool heater is to replenish the heat loss at the surface of your pool. Most heat loss happens over night. Without a solar cover, there is no way to make up for the loss. That’s when having a higher BTU size comes in handy.
How to calculate the size of a pool heater?
Heater size in BTU/hr. = Surface Area x Temperature difference x 12, where Surface Area is the area of the pool in square feet, temperature difference is the result of (desired pool temperature – current pool temperature), and 12 is our constant number based on the assumption that wind speed is around 3.5 miles per hour.
How many BTUs does a pool heater need?
Current pool heaters are 85% to 90% efficient. This means if you have a heater with an input of 400,000 BTUs, you’ll be getting 340,000 BTUs of output based on 85% efficiency, though this drops over time due to normal wear and tear. Understanding BTU’s helps you determine the necessary heater size for the volume of water in your pool.
How big of a gas line do I need for a pool heater?
The heater size will also require you to have the correct gas line size, both in diameter and length. For example, if you previously had gas pumping through a 20 foot long, ¾” pipe to a 150,000 BTU heater, an upgraded 400,000 BTU heater would require a larger 1¼” pipe to run gas the same 20 feet.
How many gallons of pool water is needed to heat 30 degrees?
In order for 20,000 gallons of pool water to heat 30 degrees, you would do the following calculations: Now, divide this Btu total by 24 (hours) to determine the Btu/hour required to heat the water:
