Frequently Asked Questions
What size propane or gas pool heater do I need for my pool?
One formula commonly used to calculate propane/gas heater BTU requirements is the following: BTU = (surface area/3) x 100. For an easy estimate, use our pool heater BTU calculator located on our pool heaters page.
What's the difference between a gas heater and a heat pump?
Gas heaters (propane or natural gas) heat pool water quickly and can work in any climate. Heat pumps are energy efficient and better suited for regular heating in warmer environments, though they work more slowly because they use outdoor ambient temperature and the heat generated from the pump to heat the pool.
How long does it take for a gas pool heater to heat a pool?
Heating time depends on your pool’s size, heater type, and outside temperature. On average, gas or propane heaters are fast and can raise the temperature by 1–3°F per hour.
