Choosing an above ground pool heater is an important consideration for any pool owner to think about. That’s because a pool heater for above ground pool models can not only really extend the swimming season but can make the swimming environment even during warmer months. Buying one of these heaters will prevent you from having to close down your pool too early at the end of summer and may even allow the pool owner to open it earlier in the late spring.
Of course, some people who live in warmer climates don’t feel like they really need one of these units for their pool. After all, it’s warm all year round so they figure they don’t need one. However, this isn’t always the case. Often times, nighttime temperatures can dip—even in warmer climates—to temperatures that wouldn’t be comfortable to swim in. This is when one of these heaters can really come in handy. In fact, some types of heaters work better in warmer climates. Take the above ground pool solar heater. This heater can soak up the rays of the sun all day and release that heat during the nighttime hours so the pool can be enjoyed day or night.
Some people get hung up, however, on what type they should buy. They bounce back and forth between the various heater types and have difficulty settling on just one. This is why I’ve decided to write this guide to help you choose the right above ground pool heater for your particular needs. I’m going to start by telling you about some of the brands currently available and then I’m going to pivot to tell you how to choose the right type for your pool and your particular needs. Let’s get started.

Heating Options for Above Ground Swimming Pools
Since there are a number of different pool models available, from above ground pool electric heater units to solar ones to ones powered by propane, it’s important to take all of your options into consideration.
Here are some things to consider when buying a new heater for your pool.
Types of Fuel
When it comes to pool heaters, there are four basic types: electric, natural gas, solar and propane. Natural gas and propane units do a better job at heating pool water quickly when used occasionally and do a good job at maintaining the temperature of the pool if left on all of the time. However, gas ones are also more expensive to run than solar ones or electric ones. Electric heaters are cost-effective and can be used to heat the pool year round. Solar panels can maintain water temperatures of around 80-degrees but only in areas which have a good amount of sunlight.
Another thing to consider is the size of the pool. Large pools are often difficult to heat with solar heating units unless you use several units on the same pool. As far as gas units go, the higher the BTU the quicker they will be able to raise the temperature of the water. 1 BTU will raise the temperature of one pound of water 1-degree.
The more BTU a gas heater has, the faster it will raise the temperature of the water in the pool.
The higher the BTU, the more efficient it will be as well. Always check with the pool heaters listing to see how big of a pool it is capable of heating.
Another thing to consider is whether the unit you want to buy has a control panel or not and if it does, what type it is. Nowadays, digital control panels are not only the most efficient and give the user a greater control over the temperature of the water but often also comes with a temperature monitor. Cheaper models often don’t have this temperature monitor, which means that you’ll have to buy an external thermometer to keep track of water temperature and adjust the unit manually.
Professional Installation Needed
You should also take into consideration whether a unit you’re thinking of buying needs to be professionally installed or if you can install it yourself. If it needs to be professionally installed, then this is an extra expense that adds to the price of the heater. Unless you are specifically trained and certified for the job, then DO NOT attempt to install a unit that’s supposed to be professionally installed.
A Few Final Thoughts
Now that we’ve covered some of the more popular heater models available and have gone over some of the things that you need to look for before you purchase a pool heater, it’s time for one last thing. Purchasing a pool heater, whether it’s a solar one, a propane one or an electric above ground pool heater is something that should be taken quite seriously.
After all, it’s a major investment. If you choose a cheap, lesser quality model than you could spend even more money trying to rectify your mistake then you would have spent by just purchasing a quality one in the first place.
