Best Pool Heater Buying Guide
Now that you have learned all about some of the best pool heaters you can lay your hands on, it is time to know what to exactly look for before buying a good pool heater.
- Type Of Pool
Firstly, you should look at what kind of pool you own, either an in-ground or above-ground swimming pool. Then, you should select a pool heater that works best with either type.
- BTU Units
Next, check how many BTU units the product can generate. If you have a larger swimming pool, then it is better to go for a heater that can produce a great intensity of heat to warm up the pool efficiently.
Select a heater that has a rating that’s more than your pool surface area. This will reduce the overall heating time of your pool.
- Weather Conditions
The outside weather may have an impact on the type of pool heater you choose to get.
If the place you live in is dominated by clouds and low temperatures, then, it might not be a good choice to get a heater that runs on solar energy. Due to the lack of the sunlight, the working may get affected.
However, if your house does not have a steady supply of natural gas majority of the time, then natural gas heaters might also not be suitable for you.
And, if you can afford them, pool heaters that depend on electricity as its power source may be your best pick.
- Gas Emissions
Look for a heater that releases a low level of harmful gases such as nitrogen oxide into the surroundings. This keeps the air around you comparatively clean and safe to breathe in.
Being environment-friendly, the pool heater keeps the environment safe as well. So, that is another plus point.
Remember to measure the space that is available for the fitting of the pool heater prior to the purchase. This way, you can have an idea about the size of the pool heater that will be right for your place, and you can shop accordingly.
Usually, it is good to go for heaters that have a compact and sleek design as it is easier to take them through smaller gates and spaces. Also, they will not consume a large area in your house, leaving room for other important things.
However, if you live in an area where high winds and low levels of humidity are common, then it may be a good decision to go for a large pool heater.
- Type Of Pool Heater
It’s good to know what you are looking for before searching the market. So, there are different types of pool heaters available for you.
- Natural gas or propane heaters rely on gas sources in order to carry out its functioning.

Therefore, you can choose from these available options and see which suits you the best.
Pool Heater Vs. Heat Pump
Many people often find themselves confused between pool heaters and pumps.
Swimming Pool Heater
They can work on natural gas, propane, or electricity. Moreover, the heating rate is pretty quick, and overall, pool heaters have a lower cost.
In addition, they are easy to install, and the process takes little time.
Furthermore, pool heaters come with the capability to maintain the temperature of the water, no matter what the outside conditions are. This is because they do not depend on the outside air in order to carry out their task. Hence, they can work efficiently in any kind of weather.
Most pool heaters can generate enough BTUs to heat up a large area of the pool.
Also, they are suitable for any size of the pool. From that in your house to those big commercial pools, these heaters can reliably increase the temperature of pool water.
However, they don’t last as long as heat pumps as their overall life is lower.
Heat pumps generally last longer than a swimming pool heater due to their longer lifespan.
They are dependent on the surrounding air for their functioning. The air passes through an evaporator coil that uses heated refrigerant to warm up the water in the pool.
Also, because of the above, the heat pump does not work on natural gas or propane, thus reducing the functioning cost of the heater.
Plus, they do not consume a large amount of energy, thus going light on your monthly electricity bills.
Moreover, they do not release greenhouse gases, such as carbon dioxide, into the surroundings, therefore keeping the environment safer and cleaner.
However, they cannot function properly when the outside temperature drops below 50 Fahrenheit. So, that is a disadvantage. Also, they might not be able to work efficiently in different seasons, such as winter.
Best Type Of Pool Heater
Well, there are several types of swimming pool heaters that are available in the market. You can choose from any of them that fit best to your requirements.
- Natural Gas/Propane Pool Heater
This type of heater will run on the natural gas supply of your house. It can rightly keep the pool water at a constant temperature that you have set, no matter what the weather conditions are outside. So, this can be a good pick for those who live in places where the weather does not stay the same for long.
Also, this type of heater takes less time to heat every part of your pool water efficiently. The gas burns inside a combustion chamber, producing heat as a product.
Then, the pool water passes through the copper coil located in these chambers. Here, the temperature increases, and then returns to the pool.
Moreover, you can switch between the sources anytime you wish with a quick method.
However, these pool heaters are only a reliable option if you frequently want to heat your swimming pool.
- Electric Pool Heater
This kind of pool heater consumes electricity for its respective working. These are not very expensive as compared to the other type of heaters, thus saving you money.
Furthermore, they make the right pick for smaller pools, or portable spas as they use electric current to generate heat. So, a small area will experience a greater amount of heating.
The heater collects heat from the surrounding air and sends it towards a heat exchanger where it warms up. Then, the heat is distributed uniformly through the pool water.
Plus, they also do not rely on outside conditions for their working. Thus, regardless of the temperatures outside, the heater will efficiently warm up your pool as you desire.
Also, they heat up the water pretty quickly.
But, they do consume a large amount of electricity for functioning that might have an impact on your bills.
- Solar Pool Heater
As apparent from the name, these pool heaters depend on the sun’s energy for their functioning. They have solar panels that absorb the heat energy from the sun, which is used in heating the swimming pool.
Moreover, they are not very costly and save operational costs in the long run. One way is that it does not need gas or too much electricity, hence saving up the money that may be required for that.
In addition, it is totally eco-friendly. The heater does not release any kind of toxic gases that may be harmful to the surroundings or to human health. Thus, it keeps you safe from bad air.
As a result, these heaters are best for places that experience bright, warm sunshine majority of the months. It will comfortably increase the pool temperature by almost 2 degrees, making it more enjoyable.
In the end, we think that a solar pool heater can turn out to be the best choice as it totally relies on solar energy. Moreover, it is friendly to the environment and is relatively cheaper.
