There’s nothing quite like taking a dip in a warm, welcoming swimming pool. Even on a hot day, stepping into an ice cold pool is not a pleasant experience. But what types of pool heaters are there? How do you know which one is right for your pool? Let’s take a look at the four main types of pool heaters.
Electric Resistance Heaters
Electric resistance heaters use currents to continuously create heat. This heat is then captured by the unit’s resistor and, when water washes over it, heats the pool. Since this option requires large amounts of electricity, it is ideal for smaller pools or portable spas. Electric resistance heaters are generally inexpensive, are not dependent on air temperature and do not produce pollution. However, electric resistance heaters are costly to install and incur high monthly energy costs.
Gas heaters use propane or natural gas to create heat and are widely used. Water passes through coils heated by the gas heater which enables a pool to heat quickly. Installing a gas heater system in a pool is inexpensive compared to other options and is not reliant upon air temperature. Unfortunately, gas heaters have a life span of only five years and are expensive to maintain. Additionally, air pollution emitted from gas heaters is a consideration for many pool owners.
Heat pumps, like electric resistance heaters, use electricity to heat a pool. Unlike other options, some heat pumps are dependent on air temperature. Heat pumps are an energy efficient and environmentally friendly heating option for pool owners that will last up to 20 years. However, heat pumps take longer to heat an entire pool and are often expensive to purchase.
Solar heaters are becoming a popular option for many pool owners as they use the sun’s heat to naturally warm pool water. This direct heat transfer is energy efficient and requires little maintenance. The booster pump of a solar heater is generally the only part of the system that requires maintenance. However, solar heaters are not year round heating solutions as pool temperatures will vary in cooler months.
Installing a pool heater is a great way to get the most enjoyment out of your pool. Before making a decision, be sure to take into account the ongoing costs of operating a system and its reliability. Once you’ve found the perfect heating system for your pool, jump right in with confidence!
