What are Solar Pool Heaters? How Do They Work?
Solar pool heaters are undoubtedly the most inexpensive pool heating mechanisms available out there, and they work just as well as any other heat pump.
The only difference is that solar pool heaters will only work at full capacity when it’s hot out, otherwise its efficiency will significantly diminish when it’s overcast.
These are the type of heater which collects the energy from the sun to warm your pool water.
But this works in a different way as the water from your pool is pumped through the filter which is situated on the solar panels situated on the top of the pool or on the side.
They are similar to the normal solar panels which are known as PV solar panels and there are pipes circulating throughout the bottom of the pool which makes the pool water warm.
There are many pools of solar panels which include flow controlling valve with automatic sensors which can provide you with feasibility and flexibility.
When you set up the desired temperature these features will detect the water temperature coming out of the solar panels and compare it to your desired set temperature.
When the pool water is chilling or cool this device diverts it towards the solar collectors which automatically warms the water according to the temperature, when the pool water is hot so the flow controlling valve stops furthermore hot water entering the pool.
Yes, they work efficiently as they are managed with an automatic solar system and the mechanism hence making them work perfectly fine and produce the best results.
Benefits of Solar Pool Heaters
Essentially there are many benefits of Pool Solar Panels but there are 5 main reasons which can make your mind buy and install this system in your pool.
Like you can have a longer swimming session as an average pool owner might use the pool for up to 4 to 5 months and the rest of the time the water is cold and unbearable.
With the pool solar panel, you can have a proper warm and heated water for your pool even in starting winter months.
Other than that, it saves energy while using solar energy to power it hence saving fuel cost and pollutions.
Thirdly, it helps to save the environment as combustion is the main reason for global warming in this era.
With that said, it requires low maintenance and it quiet and silent hence making this cost-efficient and affordable in every aspect of a budget-oriented person.
How Do Pool Heaters Work?
Electric pool/spa heaters use a resistor element and electrical current to generate heat to warm your pool water. After it is heated, the water is pumped out of the unit and circulated back into your pool. Electric pool heaters are quite effective, but they require a large amount of electricity, which could become costly. Your electrical panel may also need to be modified to accommodate the additional load.
Electric heat pumps transfer heated water to cooler areas of the pool so the overall heated temp is maintained. The system takes warm outside air into the compressor and compresses the heated refrigerant inside. The hot compressed refrigerant heats the water while cold air is expelled.
Gas pool/spa heaters can heat quickly and maintain your desired pool temperature regardless of weather, temperature, or climate. They operate on natural gas or LP and use your existing pump and heat coils to circulate the water and heat your pool, hot tub, or spa. Your pump circulates pool/spa water through the filter to the heater where gas fuel is burned in the combustion chamber heating copper coils the water passes through and is heated before it is returned to the pool.
Solar pool/spa heaters use energy from the sun, a solar collector, filter, pump, and control valve to heat (or cool) pool/spa water. Your existing pool pump circulates the water through the filter and then through the solar collector where it is heated and returned to the pool. This process may be done at night to cool the pool during peak hot climate months.
Types of Pool Heaters/Heat Pumps
Electric Pool Heaters
Electric pool heaters are extremely effective, reliable, clean, and require less space than other types of pool heaters. They are easily installed and operated whenever there is power and effectively operate in any weather. However, your regional cost per kW/Hr of electricity and how many hours a day you intend to run the system may increase your utility bill making your electric pool heater more costly to run than gas or solar unit. For these reasons, electric pool heaters are recommended for smaller pools, hot tubs, spas, or in climates where shorter periods of heating is needed.
Electric Heat Pumps
Electric pool/spa heat pumps do not generate heat. They move heat to where it is most needed to ensure your pool is maintained at a consistently comfortable temperature. Heat pumps are easy to install and use and cost little (50% – 75% less than gas heaters) to operate. They provide a reliable, budget- and environmentally-friendly, efficient means of heating and cooling your pool/spa’s water. Electric heat pumps are a good addition for larger pools. They operate most efficiently when the air temperature is 45+ F. deg. A typical electric heat pump can last up to 20 years.
Gas Pool Heaters
Gas pool/spa heaters are most commonly used because they are efficient in any climate. There is no minimum outdoor temperature restriction since they burn fuel (natural gas or LP) in a combustion chamber. They heat quickly (faster than other types of pool heaters), which makes them especially a good choice for hot tubs, spas, and pools that are not used regularly.
New model gas pool heaters are reliable, energy efficient, and less expensive than heat pumps. They are also more environmentally-friendly than in the past. They may be hardwired to natural gas or propane sources. Professional installation costs may reduce any initial cost savings. Their operating cost is determined by the cost of propane or natural gas. Propane gas typically costs more than natural gas. A typical gas pool heater can last as long as 15 years.
Solar Pool Heaters
Solar pool/spa heaters maximize energy efficiency and environmental friendliness. Initial purchase and installation costs may be higher, but they are affordable to operate and require little maintenance. Only solar panels/collectors, the sun, pump system, and enough space to install the collectors are needed. Solar heaters tend to take longer to heat the water than electric or gas heaters, however. They are less efficient in colder or cloudy weather, so a backup heater may be recommended. A typical solar pool heater can last as long as 20 years (barring no glazing/tempered glass panel breakage).
7 Things to Consider in the Best Above Ground Pool Heater
When you’re choosing your own pool heater, there are several factors you may want to consider.
One of the things that make a pool heater great is how efficiently it heats your water. Gas heaters are usually the quickest and most effective, but that doesn’t necessarily mean it’s what you need.
For your climate, pool size, and type of pool, a solar blanket may be just as efficient in meeting your heating needs.
A good quality pool heater will be made out of quality materials made to last and withstand your particular environment.
3. Size of Pool
The size of pool you have will make a difference in the type of heater that will work best for you. For example, very small pools may only require sun rings to stay toasty warm, while a very large pool might need something better.
Gas heaters are the only pool heaters that can sometimes be harmful to the environment because of their emissions. However, most newer models are made with this in mind and meet emissions standards in even the strictest of states.
5. Ease of Installation and Maintenance
The right pool heater for you will be easy to install and maintain according to your own standards and abilities.
Affordability means something different for everyone. But keep in mind the cost of the unit is not all that you need to consider.
Also take into account the cost to maintain it and how often it will have to be replaced.
Again, your climate is one of the most important factors in choosing a pool heater.
For example, pool owners in Florida might like using a solar blanket to take the edge off the water temp. But pools in Maine often require something more just to keep the water bearable.
Reasons Why You Need an Above Ground Pool Heater
The truth is, most people don’t necessarily need a pool heater, but the comfortable swimming conditions they provide is certainly preferable. After all, when you purchased your pool, you probably hoped to get as much enjoyment out of it as possible, right?
Of course, the exceptions to this are pools in colder climates, like some northern areas. If you have a pool where you don’t have many days of warm swimming weather, you might fall into the category of actually needing a pool heater.
Either way though, jumping into a pool that doesn’t make your toes curl and chill bumps pop out on your skin is usually the way to go.
So, what are some reasons you might need a pool heater?
Extended Pool Season
With a pool heater, you’ll get to use your pool longer than most people. Pools without heaters may be closing down for the winter long before the temps outside dip to colder weather.
Relaxed Muscles and Joints
Aside from pure enjoyment, heated pools also have a few health benefits. One of those is that it relaxes muscles and soothes achy joints.
Swimming in warm water is known to help relieve stress and depression by relaxing your body and mind.
How Much Does It Cost to Run a Pool Heater?
The operating cost of a pool heater varies according to the type of unit you have. Electric pool heaters can run an upward of $50 per month extra on your utility bill. The time of year and local rates may make the cost less. Gas pool heaters are usually cheaper at about half the yearly cost, particularly natural gas.
Even less expensive are heat pumps. In comparison to gas-powered pool heaters, heat pumps cost cents on the dollar to run. Then, there are solar swimming pool heaters. Since solar heaters utilize the sun’s rays, the cost to use them is minimal.
How Do I Correctly Size a Pool Heater?
To get the ideal efficiency from your pool heater, it should be sized corresponded to your swimming pool’s capacity and the region in which you live. The more water your pool can hold, the more BTUs the pool heater should have. If you live in a cold climate, your pool heater needs plenty of power behind it. Conversely, a warmer climate necessitates a less powerful swimming pool heater.
What’s the Average Heating Time?
Of course, you want to enjoy the relaxing and warm water of your swimming pool as soon as possible. However, it takes a little time for a heater to warm the water upon startup. Even though the heating time varies by the unit’s BTUs, the pool’s size and other factors, the approximate temperature increase rate is approximately 20 degrees in 24 hours.
How Much Maintenance Is Involved?
A pool heater is a large appliance. As such, it requires routine maintenance to ensure it lasts for years and operates at peak efficiency. Professionals recommend that pool owners get their swimming pool heater serviced on an annual basis. By adhering to a once-per-year maintenance schedule, you can avoid the cost and hassle of mechanical repairs.
How Long Do They Last?
Like air conditioners and heat pumps, pool heaters are built to last. A particular pool heater’s lifespan depends on the type of heater and how well it’s maintained. For instance, gas and electric heaters can last at least 10 years while heat pumps may work for as long as 20 years.
With proper maintenance, your swimming pool heater can reach and even exceed the end of its expected lifespan. It also helps to run the heater regularly, which prevents the moving parts from locking up or corroding.
Considering the benefits of pool heaters, it is important that you don’t overlook the importance of installing one for your pool or spa. Just keep in mind that there are available in different sizes, designs, and types.
You should pay attention to your unique circumstances, know your budget, and decide whether you need a solar, gas, or electric heater for your pool. They all have their pros and cons, so weigh them carefully to answer, What are the best pool heaters on the market today?
