What to Consider When Choosing the Best Natural Gas Pool Heater
You need to spend a leg and arm to get an efficient pool heater. When it takes a lot of investment to get one, you don’t expect it to run just for two-three years. Considering the below criteria will help pick the best pool heater that functions well and will last for years.
First off, consider the pool size before choosing a pool heater to heat your pool. It’s indispensable to measure your swimming pool. Otherwise, you will end your buying session by picking the wrong unit. For example, a pool heater that is designed to heat a 15000-gallon pool can’t heat a 35000-gallon pool. So, choose a swimming pool heater based on your pool size.
How efficiently the pool heater you will pick heats the room is the must. The efficient heating ability depends on the heat output a pool heater delivers. Fortunately, every pool heater we listed above produces 200000-400000 BTUs or over. So, you can go for any of them to heat your large swimming pool.
The longevity of a pool heater depends on the construction material. Each of the heaters we mentioned uses cupro-nickel or galvanized metal. As a result, saltwater can’t bring any damage to your pool heater as the heater resists corrosion and rust.
Ease of Use
You don’t want to buy a heater that you can’t operate, right? Fortunately, each of the pool heaters on the list is simple and convenient to run. All of them include a thermostat feature to adjust the temperature. Plus, every heater comes with a digital LCD to control the entire unit.
Energy Efficient or Not
Operating a pool heater takes a lot of energy. Though the price of natural gas is affordable, it still adds up the cost. The industry-leading design of the pool heaters we listed reduces circulation pump run time to offer energy savings.
