It saves electricity, plus you won’t have to pay for gas or electricity. However, it may not be the fastest method to heat a pool. The heating output depends on how many solar panels you put in your pool and the quantity of sunlight it receives.

Why you should own a pool heater

If you want to keep your pool warm in the winter, you need a heater.  Here are other reasons why you should own one:

Provides for a swimming season all year-round

Keeping a swimming pool open all year round is fine for some regions because of their climate.  However, for some places with colder climates, there are some months of the year which require a pool heater. This way, you can extend the swimming season by heating your pool. You can then swim whenever you like. No need to worry about freezing pool water.

Maintains appropriate temperature

Temperature swings between day and night are common. It even occurs in places with a warm climate. To address this, you need to own a heater. Regardless of the weather, your pool will remain at a reasonable temperature thanks to heaters.

Can be an investment

Although pools are pricey, if you keep it well-maintained, it will increase the price of your property, whenever you want to sell your home. Aside from its financial benefits, the comfort it brings is also a good investment.

What to consider when buying the best pool heater

There are several factors you should consider when buying a pool heater. If you bought a heater that is not compatible with the pool you have, you’ll end up with a low-performing or even worse, a damaged heater. That is why, it is important to consider the pool type you have, the size, and even the type of power supply you have at home. Here are other tips as well to help you choose the best pool heater.

Fuel type

Pool heaters can be electricity, gas, or solar-powered.

Gas-fueled type

In spite of their widespread use, gas pool heaters are notoriously expensive to run because of the natural gas or propane they use. As a result, propane heaters may need to be refilled and/or replaced on a frequent basis.

Solar-powered type

Pool heating with solar heaters does not need any fuel at all since the absorbed energy from the sun is used. This sort of pool heater, on the other hand, might take longer to heat your pool, and its efficacy is directly related to how much sunshine it receives. Because of this, they’re ideal for locations with a lot of sunshine, but less so in areas with a lot of cloud cover.

Electric-powered type

In terms of initial investment, electric heaters cost less than gas pool heaters, but their continuous power expenses surpass those of gas heaters. There are two kinds of electric heaters.

Direct flow heater

Direct flow heater heats water directly as it flows through it, using electricity. Compared to a tankless water heater, this technology is compact and does not need a lot of room.

Heat pump-based electric heater

It heats similar to that of an air conditioner, but in a reverse manner. These heaters aren’t cheap, but compared to gas pool warmers, they’re a better deal. Colder climes won’t be able to benefit from this form of heater since it depends on the surrounding air temperature.

Pool compatibility

You must ensure that the pool heater you choose is safe and effective for the sort of swimming pool you have before purchasing it. If you don’t, you might end up with faulty equipment or a damaged pool structure.]

Inground and aboveground

The kind of heater you need will also depend on the type of pool you have—whether it is in ground or aboveground. There are heaters for both and, although some are interchangeable, the majority of them can only be used with one or the other.

A good illustration of this is that the best heaters for above-ground pools are often smaller and more energy-efficient than those for in-ground pools. As a result, you should always make sure that the heater is suitable with your pool before using it.

Saltwater

Whether the heater you’re contemplating is suitable with your saltwater pool is also an additional consideration. A saltwater pool heater may theoretically be used with any kind of heater, but a non-saltwater heater is more likely to corrode and lose function over time due to the use of copper heating elements. Internal components may corrode due to the saline water.  Hence, salt water pools need a heater with a cupronickel heat exchanger because it is more resistant to corrosion.

Pool dimension

When deciding on a pool heater, it’s important to keep your pool’s dimensions in mind. The more gallons of water you have in your pool, the more work the heater will have to do to increase the temperature. In order to heat the water more effectively, a pool heater with a higher BTU rating is recommended for bigger pools.

Using a calculator provided by certain manufacturers of pool heaters will help you quickly and simply determine the proper size heater for your pool. For instance, with Raypak’s pool heater cost estimator, you can compare energy prices for various sized pool heaters based on factors such as zip code, size, and months of the swimming season.

BTU output rating

BTU stands for British Thermal Unit. To increase the temperature of one pound of water by one degree Fahrenheit, one BTU is needed. The A BTU output rating may be found on every pool heater. BTUs ranging from 150,000 to 400,000 or more for the majority of units.

You can also calculate the BTU output rating by yourself. Remember that this is an estimate of the total BTUs needed to increase the temperature of your swimming pool. In most cases, this is a 24-hour period, although it might be shorter or longer depending on how long it takes your pool to achieve the desired temperature.  

Here’s how to compute the BTU output rating so that you’ll know how many BTUs to check for in a pool heater’s BTU rating.

  1. Calculate the required BTU to heat your pool by one degree. Multiply the weight of a single gallon (8.3 pounds) of water by the volume of your pool’s water in gallons.
  2. Calculate the defense between your desired pool temperature and the coldest air temperature. For instance, a desired temperature of 80F with a current temperature of 60F has a 20F difference.
  3. Find the product between the said temperature difference and the required BTU to increase the pool’s temperature by one degree. difference by the number of BTUs required to increase your pool’s temperature by one degree.

Climate

Where you reside may be the decisive factor regardless of the size and kind of pool you have or the way you utilize it.

For warm areas

Heating requirements are less stringent in warm areas. If you reside in a really hot climate, you may even want to consider an electric heat pump with water cooling capabilities.

For cold areas

There is such a thing as having too many BTUs in a pool, but for cold regions, the rule is that the larger the pool, the better. A higher powerful heater is required for more warmth. In pools that are situated in places where nighttime temperatures dip below freezing. Because it needs additional heating, gas heaters with the greatest heating capacity are your best options.

Budget

Determine how much money you have to spend before purchasing a heater for your pool. Also remember to take into consideration the price of the heater’s installation, as well as the heater’s maintenance and lifespan. If you’re contemplating an electrical model, consider your home’s electrical capability. For gas-fueled heaters, the kind of gas you have access to or the expense of installing a new gas line will also have an impact on the type of gas heater you need.

Ability to conserve generated heat

When a heater is installed in a pool, water runs past it, absorbing heat from it. Insulating materials like foam or plastic are used in heaters to keep the water at a consistent temperature. For instance, solar pool heaters make advantage of these since they must be exposed to the elements in order to absorb heat from the sun. As a result, the materials utilized and the structure of the heating tubes must strike a compromise between functioning and the conservation of the generated heat.

Product casing

The heater’s casing functions as additional insulation which prevents it from losing heat before it leaves the pump. It also protects it from the elements, impacts, and temperature swings. Moreover, it has an aesthetic benefit, to make your heater attractive. With solar pool heaters, the casing covers a large area in order to maximize the amount of heat and sunlight absorbed by the surface.

Ability to control flow rate

The amount of water that may travel through a pump in a given amount of time is known as the flow rate. It gives the ability to increase or decrease the amount of water that can flow via a pool heater. It’s like turning on or off the water supply valves, to control the water flow. Some pool heaters have this feature which allows owners to adjust the water flow rate, depending on their preference. However, because the pump and filter systems normally manage the water flow rate, this isn’t a popular feature on pool heaters, either.

Installation Ease

If you want to install the heater yourself, make sure you take into account the difficulty of the installation process.

For solar pool heaters

Installing a solar pool heater is a lengthy process. As long as there is enough room and you have the necessary equipment and ladders, these heaters are the simplest to put up for a DIYer.

For electric pool heaters

The installation of an electric pool heater is usually left to the specialists because of the complexities involved. There’s no substitute for having a professional electrician connect and check the electrical system, particularly when it’s close to water or other potentially dangerous substances.

For gas pool heaters

The most challenging part of installing a gas pool heater is getting the gas and electricity to work together. Before utilizing a gas pool heater, check the connections with a professional, just like you would with an electric one.

Warranty and maintenance

The heater must be winterized (depending on where you live) cleaned, and repaired on a regular basis. A professional should inspect any sort of pool heater at least once a year to verify that the system is working properly; however, if the pool heater is used all year round, it should be checked twice a year.

An extended warranty term will ensure that you have access to replacement components or even an entirely new heater in the event of a breakdown.

Other features

Number of thermostats

Small-sized heaters typically have only one thermostat. However, for both pool and spa use, a dual thermostat heater is preferred.

Resistance to wind

Models with a wind-resistant design or forced draft system eliminates the effects of external weather on your heater’s heating capacity.

What sort of pool heater should you get?

Choosing the appropriate pool heater for your requirements is critical, so understanding the different types and how they function is a good place to start. Pool heaters are classified into three types: gas pool heaters, electric pool heaters, and solar-powered pool heaters. Heat pumps are another sort of pool heater, however they are classified as electric pool heaters.

The key distinction between the three is that they all derive their power from various sources. This has an impact on factors like as operating costs, acceptable climates, and the difficulty of the installation procedure.

What type of pool heater should you buy?

Pool heater selection depends on where you reside as well as the heat source that is accessible in your house.

For those who live in the north:

Gas heater if you have access to gas

Heat pump if no access to gas

For those who live in the north:

With gas in the south, a heat pump or solar heater is best.

For those in tight budget:

A solar-covered pool heat pump. Even if the initial outlay is substantial, the benefits will outweigh the costs in the long term.

Always remember that in order to get the best results from your pool heater, you must maintain proper water chemistry. If your heater is exposed to low or high pH levels, erosion and scaling might occur within it. Heater damage may also be caused by pools with high levels of chlorine (particularly salt-water pools).

Frequently asked questions

How big of a pool heater should you get?

Whether you choose a gas, electric, or solar pool heater, selecting the right size heater for your pool is critical. BTUs, or British Thermal Units, are used to measure gas and electric heaters. That is the amount of energy required to elevate one pound of water one degree.

The more you need to boost the temperature, the more energy you will require. It’s worth looking into one of the many internet calculators that may help you figure out how many BTUs you need in a pool heater. For more detailed advice, speak with a pool professional.

An average-sized pool takes how long to heat?

There are many variables that will affect how long it takes for you to heat this water. Some of the factors are—what is your desired temperature (and how many degrees it needs to be raised from your current one), the type of pool heater you’re using and how much ambient air temperature you’re dealing with outside the pool.

Typically, residential pools have around 10,000 and 20,000 gallons of water. It is possible to achieve the desired temperature in a swimming pool in less than 24 hours with the correct heater. Using a gas pool heater, temperatures may often be raised by 5 degrees or more in as little as 12 hours.

How long will my pool heater last?

The average lifetime of a pool heater is between five and ten years. However, it can survive a decade or more if they are installed and maintained correctly.

What are ways to maintain my pool heater?

To make sure your pool heater lasts as long as possible, do regular maintenance as directed. It is important to read the owner’s handbook and pay attention to any maintenance recommendations that are particular to your model. Here are other ways to maintain your pool heater

  • Check the burner inputs for debris.
  • Keep them free of dirt, leaves, and other debris. Use a wire brush to remove any accumulated dirt or rust.
  • For propane-fueled heaters, check your propane tank gauge regularly to ensure that you have enough gas for operation.
  • Check for leaks in the fuel lines of propane and gas pool heaters. Fill a spray bottle halfway with water and dish soap. Fuel line joints should be smeared with the mixture. If you see bubbles, you most certainly have a leak, therefore have it fixed as soon as possible.
  • Turn off the power supply and open the heater’s cabinet to remove the heater’s elements securely. 

How can I tell if my pool heater is operating well?

Make sure your pool heater is working properly by checking a few items. Your pool heater is likely performing its job if all of these parts are operating as planned.

  • Check the machine’s lights and display to see if the electrical supply is fine.
  • Adjust the thermostat higher if necessary to provide enough gas flow, and visually check that the burner is igniting.
  • Remove any barriers to water flow from the pool filter and water inlets.
  • Make sure that your heater has enough air input and ventilation.

How many degrees does my pool’s heat drop overnight?

Temperatures can drop as much as 10 degrees Fahrenheit in an uncovered pool with a large exposed surface area on cold nights. This overnight heat loss can be reduced to just a few degrees by using a high-quality pool cover.

Is it okay to turn off my pool heater overnight?

The answer depends on how often you use your pool. Most of the time, instead of turning the heater off at night, it’s better for everyday pool users to lower the thermostat a few degrees. However, if you rarely use your pool, keep the heater off until the day before they want to swim. This way, maintenance and energy costs will be kept to a minimum.

Is it okay to install the pool heater by myself?

Several factors come into play, including your degree of technical expertise, the sort of pool heater you choose, the layout of your property (such as if natural gas lines are readily accessible), and the specific pool heater itself. Solar pool heaters, in particular, may be installed by an experienced do-it-yourselfer, but in general, you should hire a professional to set up your pool warmer so that they can test it and guarantee that it is operating properly.

Is it possible to get the heaters in swimming pools repaired?

It should be possible to replace or repair the pool heater’s parts if the damage is not serious enough to render the heater useless. However, better hire a professional to handle this kind of issue.

How should a pool heater be winterized?

Gas pool heaters used in cold climates are commonly used to winterize the pools they heat. Here are ways to do this:

  • Use the valves on the gas line to shut off the heater’s gas supply.
  • The heater should be turned off, with the pressure switch opened/
  • Make sure all drain plugs are open and stored until the pool is ready for use again.
  • Use a shop vacuum or leaf blower to blow out the heater.
  • Remove any remaining water to prevent it from freezing when the temperature drops.

Bottomline:

The kind and size of your pool are two important considerations when selecting a pool heater—whether you have an inground or aboveground pool. Large inground pools often need pool heaters with more heating capacity.

Residential pool heaters typically have a BTU rating of 100,000 to 400,000, depending on the volume of water in your pool and how high you want the temperature to rise. You’ll need to choose between natural gas, propane, or electric pool heaters depending on your power supply.

With a basic cupro nickel heat exchanger and the ability to heat pools up to 13,000 gallons, the Hayward Universal H-Series W3H150FDN is the finest option you could get. The AquaCal SQ120R heater-chiller combination is also a good choice if you want greater control over pool water temps. The long-lasting titanium heat exchanger on this 2-in-1 pool heat pump allows it to increase or lower the water temperature in pools up to 25,000 gallons.
