A swimming pool in your yard is one of life’s amazing luxuries. You can cool down in the pool over the summer months, and warm up when the cools evenings set in. If you are thinking of installing a pool in your yard, then there are a few things which you need to think about. The pool itself is important, but you need to think about how you are going to heat your pool.

For the best swimming pool, you need the best pool heater, especially if you are in a colder climate. Even in the warmest climate, you need a heater which can increase the temperature of your pool by a few degrees. If you live in colder climate, then you need a heater which can increase the temperature of your pool by a lot (and often quickly).

There are a lot of things to think about before you by a top-rated pool heater. You need to know how much you are heating your pool by, the power of the heater, the power supply, and more. We have everything you need. Not only have we compiled the best pool heaters on the market, but we have an expert buying guide, which will guide you through the process.

Types Of Pool Heaters

Solar Pool Heater

Unless you live in the warmest climate in the world, you are going to need a pool heater; there is no doubt about it. The only thing you need to decide, is which kind of heater are you going to choose?

Solar pool heaters are relatively new in the pool heating world, but the technology is improving all the time. The panels are coming down in price, and the efficiency of the panels are constantly improving. If you want solar panels to heat your pool, then there are some things which you should know; both good and bad.

The bad news is that solar pool heaters are the most costly pool heaters to buy and install (we do believe that over time the price will come down, though). The other negative is that they work slowly. That is not necessarily a bad thing, as you are going to be using your pool when it is never out, and when the pool is up to temperature, it is easy to keep it there.

The good news is that there are almost no maintenance costs once you have the heater installed. There are also no monthly operating costs. Once you have your panels, they will take the power of the sun and convert it into heat for your pool. They are the most environmentally friendly heaters on our list.

Be sure that you have access to the sun where your pool and heater are going to be. If your pool is in a shaded area, then there will be less power for your heater. Do not place the heater under trees and expect it to be efficient. The clearer the area above the solar panels, the better.

Electric Pool Heater

Electric pool heaters are consistent year-round and are one of the most popular pool heaters on the market. Electric heaters are the fastest of the heaters on this buying guide list. The more energy efficient heater you choose, the less money you will spend per month. The opposite goes for a cheaper heater. You may spend less initially, but the monthly cost will likely be higher. Try to strike a balance, and always try to save money in the long-run.

Electric Pool Heat Pump

These are also electric heaters but work differently from electric pool heaters. They use electricity, but they draw the heat from the air or water and then pump that into your pool. They are slower than traditional electric pool heaters, but they work slower. They generally cost less than traditional electric heaters, but your monthly operational spend will be more. It can take some research to decide which are more cost-effective in the long-run. The one benefit of an electric pool heat pump is that they have great longevity and will outlast almost any other heater. If taken care of, these pumps can last for up to 20 years.

Natural & Propane Gas Heaters

Gas prices have risen over recent years, though with the price of oil, there is a chance that gas will become more affordable over the coming years. Due to the price rises in recent years, these heaters are not as popular as they used to be. These pool heaters are the most cost-effective to buy and will last a long time, but they are currently the most expensive to run on a monthly basis. For the time being, we would recommend a solar or electric pump, but if gas prices come down, then these pumps may become cheaper to run than electric.

How To Accurately Size For A Swimming Pool Heater

When it comes time to choose a pool heater for your for your pool, it is not quite as simple as going out and choosing the best-quality heater for an affordable price. There are many things to consider, and one of the most important is choosing the correct heater for the size of your pool. If your heater is not powerful enough, then you will not be able to heat your pool. If it is too powerful, then you could be wasting your money and not running the heater efficiently.

The first thing you should know is the volume of water in your pool. When you bought your pool, you will have been told the volume of the pool. If you do not know the volume, then it will be in your manual, or you will be able to find the information online. You should also take note of the length and width of your pool (or other dimensions if it is not square or rectangular). Once you have these measurements, you need to make a few calculations.

Every pool heater has a BTU rating. This tells you how much the heater can heat the water by and how quickly. By calculating your needs based on the water volume and dimensions, you can get a heater which will not only heat your pool but will keep it warm.

The first calculation will give you the number of BTUs you need to heat the water in your pool by 1 degree in an hour, and is as follows:

(Gallons of water in your pool * 8.83)/24

This will tell you the number of BTUs per hour are needed to heat your pool by 1 degree in 1 hour. The next calculation will determine how many BTUs you will need to heat your pool from the current temperature to the desired temperature. For this calculation, you will need the current temperature of your pool (current), the desired temperature of your pool (desired), and the BTUs  per hour (BTUph) which you calculated in the last equation. You will then use the following equation to find out the total BTUs you need:

(desired-current) * BTUph

This will tell you the total number of BTUs you will need to heat your pool. You will also need to calculate how many BTUs you will need to keep your pool at the desired temperature. You need to first find the surface area of your pool. For a rectangle, you will multiply the length and width. For any other shapes, you can find the equation for the area online. Once you have the area, you need to know the desired temperature (desired) and the temperature of the air outside (air temp). Your next equation is as follows:

area * 10 * (desired-air temp)

That will give you the total BTUs to keep your pool at the desired temperature. Whichever number is greater between this and your previous BTU number, is the number of BTUs you will need in your heater. It is always better to get e heater which is around 20% over this number, so that you are guaranteed of the heat, and if the heater loses efficiency, it will still heat your pool.

Your Budget

This will make your decision easier or harder. You silly cannot buy a heater which you cannot afford, and you cannot afford to buy a heater which will not heat your pool. When you start out on your journey to find a pool heater, you should calculate how many BTUs you need and then look at some heaters. The lowest price for a heater with this many BTUs will be the lower end of your budget. You will take this and then decide on the maximum you can spend. You can then have a range from which to shop in.

When you are deciding how much to spend, you should also consider the monthly costs of your heater. If you spend a lot at the outset, you may not have to spend anything each month. If you skimp at first, you may pay for it later.

You can get a heater from as little as $1500, and as much as $4000.

How large is your pool?

The size of your pool will directly impact the price of the heater. A larger pool will require a heater with more BTUs, which will likely cost you more money. A larger pool will also cost you more money each month. The longer it takes to heat a pool will also mean more money spent to heat it.

How quickly do you want the pool heated?

If you want your pool heated quickly, then you are going to have to spend more on a heater. Electric heaters are quick and affordable, but the quicker the heater, the more you will spend. Solar panels are somewhat of an exception. They work slowly and cost nothing to heat the pool. If you want them to heat faster, you can spend more at the outset and get bigger solar panels.

In-ground Vs. Above Ground

The type of heater will also depend on whether you have an in-ground or above-ground pool. There are specific heaters for both, and while some are interchangeable, there are some which will not work with the other. The sizes for the heaters are different, and the connections may be different too. Make sure to check that the heater is compatible with your pool.

How To Protect Your Pool Heater

You are sending a lot of money on your pool heater, so you should make sure that you take care of it. If you do take care of your pool heater, you will have fewer issues with it, have less maintenance to do, and will end up spending less money in the long-term. To take care of your pool heater, there are some simple things which you can do to take care of it.

One of the main issues with pool heaters is damage from chemicals. If the chemicals in your pool are not balanced, then they can damage the heater. You should also try to balance e chemicals in your pool so that they do not harm or irritate your skin and eyes. Pool heaters are designed to cope with chlorine, saltwater, and more, for years at a time, but too much of any of these can cause problems with your heater.

You should always make sure that your pH is between 7.2-7.8. Chlorine should never exceed 10ppm. Calcium hardness should not exceed 400ppm. You should be checking these levels regularly to ensure the safety of the swimmers, and to also extend the life of your heater. Even short-term exposure to high levels of these chemicals can damage your heater.

The other thing to check when you buy a pool heater is the installation. If you are installing yourself, you should follow the instructions exactly. If you have someone else install your heater, then you should double-check the work to ensure that it has been installed correctly. If the heater is installed wrong, then it can become damaged quickly. Your warranty may only last 6 months, and you may not be covered if you have installed it wrongly yourself. If you are ever in doubt, then have a professional install it for you.

The casing is also a possible problem point. The casings should be electrically bonded. This prevents electric shocks, especially when water is involved. It also prevents shorts in the motor. An electrically bombed casing cam stop wider problems in your pool. If the casing is not sealed, then you should not use the heater and should contact the manufacturer immediately for a replacement or a fix.

Backflow into your pool heater can also damage it. If this happens a few time, it may continue to work, but the more it happens, the more chance there is of the heater breaking. Check that there is a valve installed between the heater and the chlorine generator. If you are ever in doubt, then consult with a professional.

If you take care of your heater, then it will last for a long time. If you ever notice that there is anything wrong with your heater, if it is not working properly, if it is making funny noises, or if anything seems off, then have someone come and take a look before it is too late.

Gas Heaters Vs. Electric Heat Pumps

These are the two most popular varieties of heaters, and there is a good chance that you will be choosing one or the other. Before you do, you should know a little more about how they work and if they are right for you.

Electric heat pumps are better for summer months and warmer climates. They are a good heater for maintaining the heat of your pool, but they are not as good at taking cold water and waring it up. They take the heat from outside, mainly the sun’s heat, and use it to warm the water in your pool.

For colder climates or colder water, gas heaters are more effective. They use gas to directly heat the water, which means the heat is hotter than that of an electric heater. It does not matter what the temperature is outside; these heaters will still do the job. These heaters heat the water hotter than electric pumps, and are also great for heating hot tubs.

The climate you live in and your individual needs will dictate the type of heater you need. Always remember to try and conserve energy by keeping the heat in your pool. A cover will help to keep the heat in and will save you energy heating the pool.

FAQs

Can_I_Install_A_Pool_Heater_On_My_Own

Q: Can I Install A Pool Heater On My Own?

A: The short answer is yes. If you are confident in your abilities and follow the instructions exactly, then you can certainly install a pool heater on your own. The only problem is that if something goes wrong, then you may not be covered by your warranty. If something does go wrong with the heater, then it could end up costing you a lot of money. Of course, if you can install the heater by yourself, then it can also end up saving you a lot of money.

If you are ever in doubt, you should have a professional install the pool heater for you. You are guaranteed that everything is connected as it should be, and while you will have to pay for it, you could save money in the long run, and have peace of mind.

Q: Can Solar Heaters Be Used For Anything Else?

A: While solar heaters come with solar panels, these panels are specially configured to connect to your pool heater and heat the water in your pool. It is our opinion that these solar heaters cannot, and should not, be used for anything else. There is a possibility, that if you knew what you were doing, you could reconfigure the solar panel to give power to something else, but you run the risk of breaking the solar panel and the heater. These solar panels and heaters have been specially created to heat your pool, and we would recommend letting them do what they were created to do.

Q: Are Pool Heaters Efficient Or Environmentally Friendly?

A: That depends on the type of heater you choose. If you use a gas heater, then it is not very environmentally friendly or efficient. It is using up natural gas, which means that it is using natural resources, and there are some emissions. It does a great job of heating your pool and is more environmentally friendly than some other gas powered engines, but as far as pool heaters go, it is not environmentally friendly or efficient.

Electric heaters stoke a middle ground on both points. They are not the most environmentally friendly, but they are not the worst. The same goes for their efficiency. They do an okay job at both.

The exception in the pool heater world is the solar heater. They cost more to buy, but as they are converting the power of the sun into heat, they are extremely environmentally friendly. There are no emissions, and there is no use of natural resources. Are they efficient? They are slow, but they can still be efficient. But you know what, that is not the reason you are buying them. You are buying them because they are environmentally friendly and they will save you money each month.

Q: Are Pool Heaters Noisy?

A: This depends on the heater you are using. If you are using an electric heater, then you may have no nose at all, though the cheaper ones will make more noise than the more expensive ones. Gas heaters can make some noise, as can soar and heat pump heaters. The higher-quality heaters will make less noise than the cheaper ones.

Q: How Much Propane Does A Pool Heater Use?

A: That is a hard question to answer without knowing the type of propane heater you are using, the size of your pool, and the temperature you are heating your pool from and too. If you are heating your pool from cold to hot, then you could use up to 4 gallons per hour. You will use a lot less to keep it at the desired temperature.
