How to Choose the Right Pool Heater
There's nothing quite like standing on your pool deck in a bathing suit, ready to jump in and enjoy some time soaking up the sun in your backyard swimming pool. You think you're going to be refreshed after you take the plunge, but you might be in for a chilly surprise.
If you want to extend your summer and enjoy swimming even when it's a little cooler outside, a pool heater is essential. But choosing the right one for you takes a little more work than strolling into your local outdoor store and buying the first one you see.
Why you need a Pool Heater
Pool heaters do exactly what their name suggests — they make the water in your pool warmer. If you're eager to open your pool early in May or keep it open until late September, you'll need some help to keep it from turning into an ice bath.
Factors to consider when choosing a Pool Heater
Cost: Cost isn't limited to a heater's purchase price; you'll also need to pay for installation, maintenance, and energy costs.
Efficiency: Finding a heater that's the best size for your pool will greatly improve its efficiency. Pool covers can also help a heater operate more efficiently.
Where you live: Location and climate can have a major effect on your choice of pool heater. In warm, sunny climates, a solar heater might be great. In colder climates, consider a gas or electric powered heater.
Types of Pool Heaters
Gas Pool and Spa Heaters: Gas powered heaters are the most popular option. They heat water quickly and maintain even temperatures. They're cheaper upfront but require fuel to operate. For an inground pool, see the Pentair MasterTemp 400K BTU natural gas inground pool heater. Shop gas heaters.
Electric Heaters: Electric heaters are affordable but inefficient, best for hot tubs or small bodies of water. Shop electric heaters and heat pumps.
Heat Pump: Heat pumps are more efficient than electric heaters and last longer (up to 10 years), but cost more upfront and need air temperatures of at least 45-50℉.
Solar: Solar heaters are environmentally friendly and long-lasting (10-20 years), but expensive upfront and won't operate at night or on cloudy days. Shop solar heaters. To keep running costs down, see our ways to cut pool energy costs.
Choosing the right size pool heater
Pool heaters are measured in BTU ratings. To find the right size: Area of pool x temperature difference (℉) x 12 = BTUs needed per hour
Conclusion
Choosing the right pool heater can be overwhelming if you don't know what you need. Start by taking inventory of what your pool needs — think about where you live, how long you want to use your pool, and your pool's size. Once you do that, you'll be ready to shop for a pool heater that fits your needs perfectly. Browse all pool heaters.
