Swimming pool heaters - types and benefits

You should think about installing a pool heater if you want to take utilize the best of all these advantages regardless of whether you already have a pool or want to build one in your backyard. A pool in your backyard increases the utility, appeal, and value of your house. Any swimming pool must have a pool heater, especially during the winter months. They are made to raise the water's temperature and make swimming more bearable. Gas, electric,heat pumps and solar heaters are the four main types of pool warmers on the market.

The need for a pool heating system

Many individuals mistakenly believe that if they reside in a sunny environment, the pool would remain warm all year round. This is untrue, though. A pool heating system is necessary to regulate the water's temperature to the right level no matter where you reside. Your pool would be approximately 30 degrees during the hottest months, even if you live in one of the warmest areas. You should anticipate a more than 10-degree reduction in pool temperature throughout the colder months. On the other hand, if you reside in a region of the country that experiences colder summers, such as Melbourne, you may anticipate pool temperatures that range from 16 to 22 degrees.

When you first enter the pool, the temperature may appear to be warm enough to you, but once inside you'll notice that only the surface warms up. This is due to the sun's warmth only being able to superficially and ineffectively heat the pool. Normally, the pool's depth has a 3-degree cooler temperature. Therefore, installing a heating system for your pool makes sense. You may be able to swim all year long rather than only during the three to four months of the summer.

Benefits of pool heating

There are advantages to having a device that you may use to manage pool temperature in addition to the obvious purpose of a pool heater.

Extended usability: You are essentially increasing the time you can use your swimming pool each year by adding a pool heater. You could be able to utilise it for a lot longer than just three to four months of the year as opposed to merely three to four months. With a heated pool, you'll have more time to spend with your family, engage in active recreation, and host pool parties for your friends.

Health benefits: The location where the sun's rays meet water tends to be warmer. So when you dive in, you might find, quite unpleasantly, that the rest of the water is actually a few degrees cooler. You may control and maintain the temperature of the pool water with a heater. This is particularly crucial if you use your swimming pool for therapeutic purposes. With a pool you can maintain comfortably warm, you may keep utilising it for exercise and benefit from swimming's health advantages. By keeping your pool at a comfortable temperature, you may also stay in the water longer and benefit from its anti-inflammatory and therapeutic effects on the respiratory system.

Relaxation: With a properly heated pool, you may enjoy the water year-round. You can take a soothing swim or just settle down and unwind while floating in the pool.

It Extends: By adding a heater to your pool, you may extend the swimming season and take advantage of the ideal swimming temperature whenever you choose. Because a Heat Pump distributes heat from the air to your pool, you may use a heated pool whenever you want without seeing a significant rise in energy bills.

It Gives You More Ways to Enjoy Time with Your Family: By including a heater in your outdoor pool, you can make the most of your family time. Finding new ways to spend time with your family is made easier when you can immerse yourself in the 80-degree water at any time of the year. Think about how liberating it would be to let your kids play in your pool over winter vacation.

It Helps You Make the Most of Your Investment: The value of your property may rise if you add a pool to your house. You ought to equip the pool with a heater if you want to maximise the return on your investment. By adding a heater, you may extend the pool's season of use and get the most out of your pool's initial investment.

It Is Durable: A pool heater will allow you to maintain warm water throughout the year with very little maintenance. The heater will continue to function as needed with regular pool maintenance, allowing you to always enjoy the desired water temperature.

We may now explore the various pool heaters and their advantages and disadvantages if you are already convinced of the value and necessity of a pool heater for your swimming pool.

Types of pool heaters

There are three primary types of heaters that are frequently employed when it comes to pool heating. These heaters have gas controls, electricity and solar power. If you don't know much about pool heaters, picking one of the three might not be so simple. Here is some information that will be useful in assisting you in making a decision.

1. Solar heaters

Solar heaters are quite popular since they are a green, sustainable alternative. As a result, they perform best in locations with the most sunlight exposure. This makes sure that even during the colder months, your pool has a dependable, regular source of heat to keep it comfortably heated. Solar heaters ensure a decrease in your electricity bills and are the least expensive type to operate. Once installed, solar heaters require relatively little upkeep. You might need to get the parts checked and cleaned if yours seems to have ceased warming the pool water.

Solar pool heaters utilise the sun's energy to warm the water while being environmentally beneficial. They are the heaters with the lowest operating costs and the highest energy efficiency. They are not suited for places with little sunlight because they depend on the weather. During the colder months, solar heaters use the sun's energy to keep your pool heated. They are environmentally safe and perform incredibly well in sunny areas where your backyard receives direct sunshine. The fact that solar pool heating systems are the most affordable makes them a good option as well. They end up reducing your electricity bills drastically, which offsets their installation costs. You don't have to spend a lot of time cleaning them because they require very little upkeep. It is recommended to place the solar panels on your rooftop's southernmost portion for the most sun exposure. In this way, on bright days, it can raise the temperature of your pool by up to 2 degrees.

Solar heaters have advantages, but there is a slight problem that you might have to go around. They are powered by the sun, so when it's cloudy, it could take them longer to absorb energy. This indicates that it could take your pool anywhere from 4 to 6 hours of sun exposure to begin heating to the necessary levels. The southernmost portion of your rooftop is where the solar collectors should be placed for the most sun exposure. With a solar heater, you'll have a solar pump that draws water through a system of tubes, where it is heated and then returned to the pool. On sunny days, a solar heater can raise the pool's temperature by up to 2°C.

The greatest locations for solar heating systems are those with year-round high levels of sunshine. This will enable you to get the most out of a solar heater and guarantee that you have a dependable water heating source for a longer period of time each year. By choosing a solar heater, you can almost eliminate your need for energy sources, which will result in significant electricity bill savings. In addition to being strong and long-lasting, solar heating systems are a wise investment for a sustainable smart pool.

Note: When it's cloudy, solar collectors typically take longer to capture sun energy. In order for your system to effectively heat up your pool, it may require four to six hours of the most direct sunlight.

2. Gas pumps heater

A dependable and efficient piece of water heating equipment is a petrol pump. You don't have to rely on the sun or the outside temperature to heat your pool. They can also swiftly heat a pool. A gas system may adequately heat a pool, depending on its size, in less than an hour. The best heating method for you is a petrol pump. They are employed in hydrotherapy to revitalise your body and provide health advantages. For the greatest benefit, the pool water should be maintained at the proper temperature continuously. You may heat the pool water using petrol pumps without depending on the sun or the outside temperature. They function by swiftly heating the water with natural gas or propane. One significant drawback of using petrol pumps to heat your pool is that they could have a finite lifespan. They are also not environmentally friendly.

The most often used and trustworthy choice is a gas pool heater. They are powered by either natural gas or propane, and a combustion chamber burns the fuel to heat the water. They are perfect for anyone who want to use their pool regularly because they quickly heat the water and maintain the correct temperature. Nevertheless, they are more expensive to run than alternative solutions, and fuel prices might vary greatly. Gas pumps are the best option, though, if you just occasionally plan to use your pool during the winter months. They spare you the headache of dealing with more durable heating methods like solar installations or electric heaters. For spa pools, which are used for hydrotherapy and must be regularly maintained at the ideal temperature, gas heaters are the recommended option. Therefore, if you intend to have a spa and pool combo, a gas pool heating system may be the best option.

Note: They are powered by dirty energy or fossil fuels. Gas is not a renewable resource and is not in line with pricey green practises. Some pool owners install a backup gas pump to work in conjunction with their solar heater. When your solar heater doesn't have enough solar energy saved to heat your pool on cloudy days, this combination may be handy

3. Electric heaters

A heat exchanger and an evaporator coil are used in electric pool heating to transfer heat from the ambient air. This heats the water that flows through it and into the pool. Electric pool heaters use a heating element to warm the water and are powered by electricity. Compared to gas heaters, they are less expensive to install, but they are less effective and take longer to heat the pool. 

Electric heaters are more affordable than other pool heating systems because of how they recycle energy. Electric heaters are a good option for you if you live in a place where there is little natural light for the majority of the year. Due to the fact that they are powered by air and electricity, they can operate well in all conditions. Electric heaters can heat a pool more quickly than solar heaters. To run it, you need at least a 40-amp breaker. This suggests that you might be looking at a hefty electrical bill. Additionally, electric heaters are not environmentally friendly appliances like solar heaters.

Consider your options carefully before making an electric heater purchase if you care about the environment. These heaters are an intelligent alternative for pool heating because of this technique of reusing energy from the atmosphere. Electric heaters are a more affordable option for pool heating than petrol pumps. Additionally, heat pumps may be a better option than solar heaters if you reside in a region that receives insufficient sunlight for the majority of the year. Due to the fact that they just require air and an electrical power source to operate, heat pumps are unaffected by cloudy weather. In addition, heat pumps may heat a pool more quickly than solar heaters.

Note: A minimum of a 40-amp breaker to run it. This not only means you’ll need a lot of electrical power to use one, but also that it’s not really an eco-friendly solution.

4. Heat Pumps

Pool heat pumps are among the most energy-efficient pool heating choices. While electric resistance and gas heaters are known for their speed, the benefit comes at a cost — high monthly operating costs, to be exact. Pool heat pumps, on the other hand, are far less expensive. This is due to the manner in which they generate heat. Pool heat pumps harvest natural heat, whereas electric heaters require resistors and gas heaters consume fuel. Pool heat pumps use a tiny amount of electricity to run a fan and compressor that draws in hot air, transforms it to heat energy, and delivers it directly to your water. However, because the majority of the heat comes from nature, the draw on electricity is significantly lower than that of an electric resistance heater. Which is why pool heat pumps have a Coefficient of Performance (COP) of 6.0. This means that for every unit of energy your pool heat pump consumes, it produces 6 units in return. Consider the fact that neither gas nor electric resistance heaters have a COP greater than 1.0.

To sum up, purchasing a pool heater is a great way to make the most of your swimming pool. You can swim all year long and raise the value of your property by picking the right kind of heater. Before choosing the sort of heater that best meets your requirements, take into account the size of your pool, your location, and your budget.

Choosing the right pool heater

There are several factors to consider before purchasing a pool heater to ensure you are making the proper investment. These are some examples:

Frequency of use: If you want to make the most of your pool, a solar heater is certainly the best option, especially if you live in a sunny area most of the year. However, if you just plan to use your pool occasionally or on weekends, a gas heater may make more sense because it heats on demand. Furthermore, heat pumps and solar heaters are more expensive to install initially, so infrequent pool use may not justify the cost of installing either type.

Your budget: Consider not only the installation costs but also your long-term budget before making your decision. Consider your gasoline needs while purchasing a petrol pump. Electric heat pumps require consideration of electricity use. Solar heaters need a significant initial investment, but they are a cost-effective and environmentally friendly option in the long run.

Pool size: Remember that the size of your pool influences your heating requirements. A larger pool must be heated at a constant temperature, which necessitates the use of an effective and robust heating system. Heat pumps and gas heaters may be more dependable in this case. Again, your location and environment will influence your decision.

Logistical concerns: Whether you choose a solar, electric, or gas-powered heater, there are practical considerations to be made. If you want a gas pump, for example, you must consider the expense of running a line (depending on distance) between the gas metre and the heater. You must verify that you have enough power to sustain a heat pump. Otherwise, you'll have to hire an electrician to run a separate line from the main panel. sun heaters, on the other hand, perform best when the sun panels are near the pool equipment. This will require less plumbing work, lowering your setup expenses.

What is a solar pool cover?

A solar cover resembles a bubble wrap in appearance, which often helps retain the warm water in the pool. Evaporation of water is common for all outdoor pools, furthermore, this process may also lead to losing the effectiveness of the chemicals, and in some cases chemicals itself. A solar cover protects the pool water by decreasing the evaporation of water by 95%, resulting in better quality of water. It also maintains the temperature of pool water, which helps save energy, especially if using an electric heaters or gas pumps. Solar Pool Covers are often composed of polymer or resin, with bubbles that trap heat from the pool water. They come in a variety of forms and sizes, so you can always find a cover that fits your pool. If you have a rectangular pool, the reel will make it simple to put on and remove the cover on a daily basis. The reel can be fastened to the deck from any side. You can unroll the cover and set it on the pool, or you can roll it up and enter the water.

Benefits of solar pool covers

There are numerous advantages to installing solar coverings for your pool. Solar covers offer more benefits to the ordinary pool owner than one might think. A solar cover does much more than lend a bubble wrap appearance to your lawn when applied properly. There are numerous benefits to using these coverings.

Heating Your Water: One of the key advantages of a solar cover is that it catches UV rays from the sun, heating up the air inside the small bubbles and then transmitting that heat into your swimming pool's water. The amount of heat your pool receives depends on how much sunlight it receives every day, as well as the colour or form of the solar cover bubble, although solar covers have been known to raise pool temperatures by 10-15° F. It is critical to note that for a solar cover to work properly, the air bubbles must be face down on the water's surface.

Reducing Energy Costs: The beautiful thing about solar covers is that they heat your water in an environmentally beneficial manner at no extra expense to you. Other heaters still necessitate the use of extra energy, often gas or electricity. Using solar energy to heat your pool reduces your dependency on gas or electric heaters, saving you money each season. If your house is in a sunny location, a solar cover could completely meet your pool heating demands.

Preventing Evaporation: While an uncovered swimming pool can collect heat from the sun, the heat does not stay in the pool. Pool water is prone to evaporation when left exposed. Water evaporation is the leading cause of heat (energy) loss in swimming pools, according to the Department of Energy. The amount of water that evaporates from a swimming pool varies based on the temperature of your pool, the ambient temperature, and the humidity, but draining 1 pound of 80° F pool water requires 1,048 BTUs of thermal energy, which is drawn from the heat within your pool. The greater the evaporation of water, the greater the loss of heat energy.

Minimizes Replacement Water: By minimising evaporation, less water leaves your pool throughout the course of the swimming season. This means that less water must be put to your pool to compensate for evaporated water. The use of a pool cover can reduce the amount of make-up water required by up to 50%.

Reducing Chemical Consumption: When the water in your pool evaporates, some of the pool chemicals evaporate with it. Those chemicals must be changed to keep your pool in good balance, especially if you use make-up water. By using a sun cover to reduce water evaporation, you also prevent the evaporation of pool chemicals, reducing the need to add more. This can cut your chemical usage by up to 60%.

Blocking Debris: A plastic covering that rests on top of the water's surface keeps fallen leaves, grass blades, insects, and other types of debris out of your pool. Simply hosing this matter to one side and extracting it from the top of your cover speeds up and simplifies clean-up.

Extending the Swimming Season: Insulating your pool with a solar cover maintains the temperature of your water for a longer amount of time than leaving it uncovered, resulting in warmer water later in the pool season. A comfortable pool temperature can last throughout the autumn depending on the temperatures in your location.
