Pool Heater Buying Guide

Choosing the right-sized pool heater

This feature is directly related to your pool’s size, and it is the most important one to consider when buying a pool heater.

The larger the pool, the more powerful the heater should be. Therefore, it is essential to know the overall capacity by calculating BTUs.

If you take the standard calculation into account, then usually per 10,000 gallons of water, heat pumps are 50,000 BTUs. There are separate calculations for gas, electric, and solar pool heaters.

For instance, if you have solar heaters, you can determine how many solar panels you need using the square footage of your pool.

Considering your climate

The weather conditions and climate of where you live play an important role in determining which pool heater is best for you.

For instance, you should use solar heaters if you live somewhere with lots of direct sunlight, such as in the southern states. You will save on gas and electricity bills if you have loads of sunlight throughout the year.

Similarly, you should go for gas pool heaters if you live in the northern states where the temperatures are extreme. Solar pool heaters in areas with prolonged winters would not be a good idea.

All in all, choosing the type of pool heater based on your climate is rather convenient if not necessary.

Considering the heating time

It may not seem as if it’s important to consider the healing time of a pool heater, but it is, in fact, an important feature to consider. Why? Because knowing your preferred heating time will help you determine your heater options.

For example, you want your pool temperature to be maintained quickly, but you went on and bought a solar heater. You did not consider the fact that solar heaters take days to maintain the pool temperature.

An electric heater, on the other hand, can heat the same pool within hours. Therefore, if you don’t need to use your pool regularly, then a solar heater would be great.

However, if you are running commercial pools or spa pools or even swim regularly, then electric and gas-powered heaters would do the trick.

How environmental-friendly your heater is

The increasing threat of climate change and global warming has led to many people becoming pro-eco-friendly. They prefer products that pose the least to no threat to the environment.

Therefore, when choosing the best pool heater, you should consider how eco-friendly the product is. For instance, solar and electric pool heaters are more eco-friendly than gas heaters.

Even though solar pool heaters entail virtually no emissions, they are the most obvious choice. However, you have to deal with their limitations. On the other hand, electric heaters are quick with low emissions, but their overhead cost is hefty.

Gas pool heaters have the highest greenhouse emission out of all the types of pool heaters. But they are the most economical option, and manufacturers are also working towards decreasing carbon footprint and emission.

In a nutshell, you should weigh those factors that are a priority for you and the best-suited option for your pool.


Pool heaters allow you to have an all-year pool season. Therefore, you need to make sure you are buying the right pool heater that will last longer and provide efficient heating.

If you haven’t decided on buying a pool heater, then detailed product reviews of some of the best pool heaters in the market will help you make the decision.

Always consider your climate, your pool capacity, pool size, eco-friendliness, budget, and energy efficiency before buying a pool heater.

So, get your hands on your favorite pool heater to enjoy pool entertainment without worrying about the season.


Are all types of pool heaters eco-friendly?

To be precise, no. Each type of pool heater is a different level of environmental friendliness. Many solar and electric pool heaters have the least to no emission.

On the other hand, gas pool heaters contribute greatly to greenhouse emissions. For your pool heater to be eco-friendly, it should have a light carbon footprint, low NOx emissions, and energy efficiency.

What size pool heater should I buy?

There are separate calculations for solar, gas, and electric heaters, but the obvious equation is that the bigger the pool, the more powerful the pool heater.

Considering standards, you can consider something with 80,000 BTUs if you have a 14×28 feet or less rectangular pool. You will definitely need to go over 100,000 BTUs if you have over 18×36 feet.

Can I install the pool heater myself?

Installing a pool heater is no rocket science. Almost all pool heaters come along with an instruction manual; therefore, they are quite easy to install. Most people install the heater using instructions and then call an electrician to run the wire.

Do pool heaters have huge overhead costs?

It depends on which type of pool heater you are buying. An average monthly cost between $50-$150 of heating a pool with a heat pump is the lowest of nearly all pool heating options.

Whereas you can easily go up to $300 with a gas or an electric pool heater. To decrease pool heater overhead cost, you need to look for an energy-efficient product.

What should I do if my pool heater is running, but the temperature is not rising?

There can be a few things you can check for if your heater is running but isn’t heating.

To operate most efficiently, pool heat pumps require warm air. Therefore, you should check the air temperature because heat pumps run longer to compensate in cooler temperatures.

Next, check if the pool pump is sending enough water to the heater. There should be a steady supply of water for proper heat transfer and production.

Finally, check if there is optimal airflow by clearing any debris from the vent. Good airflow is important for the heating process of an air-source heat pump.
