How to Select a Pool Heater

Written By: poolgeek.com

In order to select the the right heater for your pool, you must first calculate the number of gallons in your pool. Once you have this number, you must then determine how large a temperature rise is needed (10 degrees, 20 degrees, etc.). After these two figures are calculated, just follow the simple formula below:

Pool Gallons x 8.33 x Temperature Rise Desired = BTU's needed

BTU's needed / Heating Time (Hours) = Proper Heater Size (BTU's)

Once you know the size of the heater you want, you just need to choose which type of heater to use. If gas, then you must choose between natural gas or propane. Natural gas is the better choice due to its lower cost and availability, while propane is perfect for areas without natural gas. If you want to heat your pool without enlarging your carbon footprint, then solar heaters are the way to go.

Title: RE: What is a better brand?

“Hi Theresa! That is a tough question to answer simply because Hayward, Pentair, and Jandy are all premium manufacturers. Any of these companies will give you an excellent product, so you really can't go wrong. I would suggest buying the product that best matches your needs and budget. For heaters, you could also consider Raypak, which is another excellent manufacturer. ”
