Get the Facts About Propane Pool Heaters

A pool heater makes it possible for you to enjoy your pool all year long. One option you have for heating your pool is a propane heater. Propane pool heaters are much more efficient and cost-effective to operate than electric heaters. They also require little maintenance beyond your regularly scheduled tank fills, making propane a clear choice for heating your pool. If you’re considering using propane for your pool heater, here are the facts you need to know.

Choosing the Right Size for Your Pool

Your pool heater needs to be large enough to keep your pool warm, but not so large that it wastes energy. Figuring out the best size can be a challenge, but start by determining what temperature you want your water to be. Then, find the average temperature for the coldest time of year in your area. Subtract those numbers to determine how much heating your pool will need. Multiply the square footage of your pool by the difference between your desired temperature and average cold temperature, and then multiply that figure by 12. This will give you an approximate amount of BTU output your pool heater should be rated to provide.

Determining How Efficient a Pool Heater Is

Pool heaters all have efficiency ratings that tell you how much heat is used to treat the pool water and how much is lost. For example, if the efficiency rating is 90%, then 90% of the energy is used to heat the pool water, and 10% is lost. Although there are lower ratings on the market, you shouldn’t choose a heater with a rating lower than 90, and ideally, you should choose one with a higher efficiency rating.

Filling Your Propane Tank

If you add a propane pool heater, your propane use is likely to increase. Talk to your propane company about changing your delivery schedule or getting more propane at each delivery, so that you don’t run out.
