How to Choose the Best Pool Heater: Factors to Consider

If you’re wondering what is the best pool heater for you and your home, you’ll be happy to know choosing a pool heater is far from rocket science. However, it does take a little planning and careful consideration. After all, the last thing you want to do is pony up for a pool heater and go through the installation process only to find out it isn’t suitable for your pool and needs.

There are quite a few factors to consider when deciding on a swimming pool heater, but the very first one to check off the list is the actual type of heater you want for your pool.

  • Solar heaters are inexpensive and won’t cost you a dime after installation, but they only work for smaller pools and take longer to heat up.
  • Electric pool heaters work better, but still take at least a few hours to begin producing warming results.
  • Natural gas pool heaters work great, but they can be costly to run.
  • You must consider your budget, needs, and lifestyle in order to pick the right type of pool heater for you.

After deciding on the type of swimming pool heater you want for your pool, you must then determine the right size heater for your pool. Most pool heater reviews simply recommend certain models and neglect to stress the importance of choosing the right size model for your pool. However, this step is critical, so listen up. pool heater reviews

Swimming pool heaters are rated according to their BTU output. Each BTU, or British Thermal Unit, is capable of warming water one degree Fahrenheit per pound. Therefore, the greater the BTUs produced by a swimming pool heater, the quicker it will be able to heat up a pool.

Since swimming pools are located in different climates and come in different shapes and sizes, to pick the best pool heater for your specific pool you must perform some basic math and calculate two variables: the temperature differential and surface area of your pool.

After you’ve calculated the surface area and temperature differential of your swimming pool, you can refer to the chart below to determine the number of BTUs you’ll need to keep your pool at your desired water temperature.

Heater Size Pool Water Capacity Pool Surface Area

  • 100,000-200,000 BTUs up to 10,000 gallons under 300 square feet
  • 200,000-300,000 BTUs up to 20,000 gallons under 500 square feet
  • 300,000-400,000 BTUs up to 40,000 gallons under 800 square feet
  • 400,000+ BTUs up to 80,000 gallons under 1,200 square feet

When you have calculated the surface area of your pool and considered these factors, choosing a pool heater is simply a matter of checking the numbers against a sizing chart like the one above. Of course, there are other factors to keep in mind as well. Durability, brand recognition, energy efficiency, ease of installation, and your budget should all be taken into consideration in order to select the very best pool heater for you and your pool.

Types of Pool Heaters

Introduction to the 3 types of Pool Heating

By Fuel Type:

Solar Pool Heater

Solar Pool HeatersSolar swimming pool heaters make use of solar panels to collect and transfer heat from the sun to pool water. The water is simply circulated from the pool and into panels where it is warmed before being returned to the pool.

It may seem obvious, but since solar pool heaters are dependent upon the sun to warm up water, they work best in sunny, warm climates. The majority of pool owners who utilize solar pool heaters also use an auxiliary pool heater at night or on cloudy days.

Pros and Cons
  • Solar heaters don’t require any additional operating costs.
  • They are extremely energy efficient.
  • Similar to heat pumps, solar pool heaters are designed to last for decades.
  • Solar pool heaters utilize renewable energy and have no emissions whatsoever, making them the most environmentally-friendly pool heating option.
  • While inexpensive to operate, solar pool heaters only work well in sunny climates.
  • They heat water much slower than other types of pool heaters.

Natural Gas or Propane Pool Heater

best pool heaterIf you’re searching for the best pool heater, chances are a propane or natural gas pool heater is what you’re looking for as they offer unparalleled heating performance. With these types of heaters, a combustion chamber is used to warm the water. Basically, water is pumped out of the pool and goes through a super-hot tube before being returned 20, 20, or 30 degrees warmer.

Although propane and natural gas heaters work the best, they can be more costly to run. Since they work so well, however, you only have to turn them on a few minutes before diving in, rather than hours or days beforehand. This allows you to save some money and provide you with convenience unmatched by any other type of heater.

Pros and Cons
  • Most gas pool heaters are less expensive than other heating options.
  • Gas pool heaters heat up water very quickly, making them ideal for anyone who likes to take short dips.
  • As the most popular type of pool heater, there are many models to choose from with solid pool heater reviews.
  • Since they run on electricity and utilize natural gas, gas pool heaters can be costly to operate.
  • Most gas pool heaters have an energy efficiency rating of 80-8 percent, making them one of the least efficient pool heating options.
  • Due to their reliance on fossil fuels, gas pool heaters aren’t environmentally friendly.

Electric Pool Heater

Electric Pool Heater reviewsElectric pool heaters warm up pool water by heating up a metal coil, which in turn heats up the water. Although electric pool heaters are often less costly and easier to install, they’re also the least efficient. Due to the amount of electricity needed to heat up an entire in-ground or above ground pool, it usually makes them an unwise choice for most pool owners.

While hot tubs and spas typically use electric heaters, they’re much smaller than pools, so they heat up faster and use less energy. Nonetheless, given their cost of operation, you’re likely better off going with a heat pump or natural gas pool heater.

If you’re thinking of going with an electric heater, make sure to review your utility company’s pricing structure, as rates usually skyrocket after reaching a set limit of kilowatt hours. This information isn’t provided in most pool heater reviews, but you’re here for an honest opinion and honesty is what you’ll get.

Pros and Cons
  • Electric pool heaters are generally less expensive than other types of pool heaters.
  • Unlike solar and gas pool heaters, electric pool heaters tend to be easier to install.
  • Electric pool heaters don’t release harmful emissions, making them more environmentally-friendly.
  • Unlike gas heaters, electric pool heaters take a while to warm up water.
  • Most electric heaters aren’t suitable for large in-ground pools.

Pool Heat Pump

best Pool Heaet PumpHeat pumps pull in warm surrounding air and use compressors to optimize the air to the right temperature. They then transfer the heated air to pool water, resulting in an efficient and ecofriendly way to warm up the largest of swimming pools.

Heat pumps are generally more expensive than the other types of pool heaters. However, they work extremely well and are capable of heating up a pool to a comfy temperature, even when it’s below 50 degrees outside and frost is in the air. While costlier than natural gas heaters, they work just as well and cost far less to operate, making them a solid option for any pool or spa owner.

Pros and Cons
  • Heat pumps are very energy-efficient and cost less to operate.
  • Most heat pumps are incredibly durable and designed to last for up to 20 years.
  • Although they run on electricity, heat pumps don’t produce harmful emissions, making them a more environmentally-friendly pool heating option.
  • Heat pumps cost more upfront than other types of pool heaters.
  • Unlike gas swimming pool heaters, heat pumps take longer to heat up water.
  • Since they rely upon outside air to heat the water, heat pumps aren’t ideal for colder, northern climates.

Wood Burning Pool Heater

Similar to an outdoor furnace, a wood burning pool heater features a combustion chamber where wood is burned to create heat, which warms up water in a circulation pipe. Although they do their job well, wood burning pool heaters are quite archaic and inconvenient, requiring pool owners to add fuel to the fire throughout the heating process.

Wood burning Pool Heater

By Usage:

In-ground Pool Heater

There’s no such thing as an in-ground pool heater per se, but some people choose to classify pool heaters according to the type of pools they’re heating. The truth is heat pumps, natural gas pool heaters, and even some solar heating systems can be classified as in-ground pool heaters. Whether or not one of these types of pool heaters is suitable for your in-ground pool largely depends on its BTU output and energy efficiency.

Above Ground Pool Heater

Like in-ground pool heaters, almost any type of pool heater can fall into this category. Natural gas heaters, heat pumps, electric heaters, and solar heaters can all be used to warm up above ground pools.

That being said, unless you have a huge 40,000-gallon above ground pool, chances are you’ll be better off going with an electric or solar heating option. If you like the power and performance of natural gas heaters and decide to go that route, make sure to use the pool heater sizing chart to determine how many BTUs your pool requires.

Above Ground vs In-Ground Pool Heaters

Whether you have a sprawling in-ground pool or a smaller above ground version, having a pool in your own backyard is a great way to have fun and beat the summertime heat. With a quality pool heater, you can even extend the swim season well into winter and enjoy warming therapeutic waters on brisk days and chilly nights.
 pool heater comparisonHowever, depending on the type of pool you have, there are some considerations to be made. This pool heater comparison will help shed a little light on the differences between above ground and in-ground pools.
In addition to being smaller in size, above ground pools lose heat faster than in-ground pools. Since in-ground pools are surrounded by insulating dirt, they only lose heat from the surface, not the sides. Above ground pools, on the other hand, lose heat from the sides as well. Therefore, although they’re typically smaller, above ground pools require nearly as much power as larger in-ground pools in order to keep up with their heat loss.

That being said, due to the size of in-ground pools, in-ground pool heaters are designed to utilize higher flow rates to heat larger volumes of water.
So, while two different pool heaters may have the same BTU output, one may actually have higher flow rates and perform better for in-ground pools.

pool and an above ground heaterAny pool heater will add some warmth to your pool. However, if you have a large in-ground pool and an above ground heater, you may only be able to warm the pool water by 10 degrees or less. With a larger in-ground pool heater, on the other hand, you can raise the temperature of your pool by up to 30 degrees, regardless of how cold it is outside. Needless to say, if you’re reading pool heater reviews in order to find the best pool heater, chances are an in-ground pool heater is the way to go.

Pool Heater vs Heat Pump

Pool Heater vs Heat PumpIf you’re considering installing a new heater for your pool or replacing an old one, you might find yourself in a dilemma. Should you choose a standard natural gas pool heater or a swimming pool heat pump? There are quality models in both categories capable of heating the largest of pools, but there are some distinct differences between the two that deserve a closer look.

Both heat pumps and pool heaters are designed to effectively heat up pools, but they do so in different ways. Traditional gas heaters use natural gas that is piped to the unit. A propane heater is another option, but they’re more costly than natural gas and you will have to look at a propane tank in your yard each day. Heat pumps, on the other hand, utilize electricity and function much like an air conditioner, except in reverse.

While both types of pool heaters will result in an increase in your gas or electric bill, heat pumps are much more efficient, resulting in little to no energy loss. This, combined with the fact that it takes much longer for a heat pump to actually begin heating up water, means heat pump owners usually leave them running around the clock. By nature, gas pool heaters produce heat extremely quickly, but are generally much less efficient. Therefore, individuals with gas pool heaters only run them as needed and turn them off after use.

As mentioned earlier, pool heaters rely on natural gas that must be piped from the street or propane that must be filled. They also need electricity in order to power the controls and the spark igniter. Heat pumps, however, only require a 220V electrical line, making them easier and less costly for most pool owners to install.

pool heater reviews

Due to these differences, many people benefit more from heat pumps in the long run. Although they generally cost more than pool heaters, they’re much more efficient and cost less to operate, even when left running.

On the downside, heat pumps aren’t designed to work well in colder weather. In fact, some heat pumps quit working below 50 degrees, making them fine for residents in Florida or southern California but less useful for those living in colder climates.

If you’re on the hunt for the best pool heater, you really can’t go wrong with either option. Both types of pool heaters have their pros and cons, so consider each of the factors we just discussed, read the pool heater reviews above one more time, and choose the type of heater that best suits your needs, budget, climate, and lifestyle.

Making the Decision
