Best Propane Pool Heater

Propane pool heaters can heat up a pool in minutes. Rather than waiting days for a solar-powered pool heater, you can be swimming and playing in the water by the time you finish reading this article. With our top pick Zodiac Jandy LXi you’ll be swimming in just a few minutes! Here’s a list of the 10 Best Propane Pool Heaters so you will never have to swim in a cold pool again.

How Propane Pool Heaters Function

The heater connects to the pool’s main water system and pumps the pools water through heated tubes. As propane gas heats the tubes, the tubes will heat the water and pump the warm water back in to the pool. According to the U.S. Department of Energy, propane pool heaters are great ways to quickly heat up a pool and maintain that temperature in any climate.

How to be Energy Efficient with a Gas Powered Pool Heater

According to the RSPEC (Reduce Swimming Pool Energy Costs), a gas powered pool heater can use up a lot of energy but by minimizing heat loss and finding the right size heater for each pool, a significant amount of energy can be saved. Heating a pool takes a lot of energy because the pool easily loses heat due to evaporation. Investing in a pool cover can help decrease the amount of heat loss as a result of evaporation.

Based on a recent study, the government of Michigan found that many gas powered pool heaters are 89-95% energy efficient. This high percentage means that almost 100% of the fuel put in to the heater is being used towards heating the pool.
