Criteria Used for Evaluation
What good is a pool heater if the water isn't warm?
Swimming is a very good form of exercise. Some people prefer to swim because it is refreshing but you lose the same amount of calories just by doing a few laps.
During the cold season, taking a dip gets a little too challenging because the water can get really cold. And a cold dip on a cold weather doesn’t sound inviting at all. But what if, the water is warm? Now, that is a different story! It becomes more relaxing, imagine that! A warm pool waiting for you at the end of the day! It will not just help you relax, it will also help soothe your body aches and pain and you will feel the stress just leaving your body and even help you get a good night’s sleep!
Another thing you have to consider when buying a swmming pool heater are the additional accessories.
Putting aside the motor eficiency, heating capacity and voltage, that are all considered as basic features, but there are also some additional accessories that can help you make your choice. For instance, not all heaters are suitable for every pool. Also, some of the products on the list have digital control systems that allow you to change the temperature to your liking.
The capacity of the pool will be another important factor to consider because some units are suitable for small to medium pools and some are for larger pools.
While you can make a rough estimate by way of a rough calculation, we suggest you consult with a professional to give you a sound recommendation.
When planning on installing a swimming pool usually these types of recommendation are already included but for some who already have a swimming pool and are contemplating on buying a new one or replace an old water heater, then we still think it’s best to consult a professional. For instance, if you are thinking of switching to solar panels you have to know how many panels would be sufficient for certain pool sizes. Because buying solar panels are in sets or pairs and you can’t just add one or two if you feel it is convenient.
Expert Interviews & Opinions
Once you have made up your mind on what to buy, there is one more thing you have to carefully look into and that is after purchase service. You have to carefully consider the warranty and what it covers, to avoid misunderstanding and encountering problems when claiming your warranty.
Some warranty has conditions and you have to clearly understand them. It is also important to know what the coverage is because some products offer a 1-year warranty on services, 5-year warranty on parts or limited warranty on a replacement.
You also have to know where the nearest service center is or what are the services covered when they install the system and most importantly, who and where to call if you need any assistance after the unit has been installed. Sometimes, even if they so have service centers you can go to, it may be far and inconvenient. You can check if they have home-service regardless of how far your house is.
Our list of best picks is a combination of different types of heating system for your swimming pool and we reviewed each product taking into consideration the criteria we have presented. The list should be helpful in narrowing your search, so you can enjoy warm dips and extend the swimming season for you and your family. If you are still unsure, you can continue search and read more reviews online for particular units you are inclined to buy.
The advantage of buying online is that you don’t have to spend time and money trying to compare one item from the other. If you buy online, there are numerous items made available to you with all the information you need. You can even compare reviews and check all the details without leaving your home.

This machine use electricity to operate but it doesn’t use electricity to heat the water itself. What it does is it creates a warm air through condensation and that heat up the water as it passes through the pump. This is very much like the principle behind air-conditioning systems and refrigerators except that it’s reversed. Heat pumps are more expensive to buy but are cost-efficient in terms of operation and maintenance.
This is a combination of solar collectors, valves, pumps, and filters to create a heating system for your swimming pool. It generates power from the sun so it is very economical. It costs a lot of money to buy and install but cost less to operate. Solar heaters have become very popular not just because it is environmentally friendly but also because of its efficiency and dependability. It works by way of pumping the pool water to the filter and through the collector. The water gets heated through the power collected from the solar panels and then it is pumped back to the swimming pool.
When choosing a solar heater you have to know that there are two types; the glazed and the unglazed. The glazed panels are suitable for areas with hash climates and below freezing temperature. These type of panels are more expensive because of the materials used. The unglazed are for areas with cold but not freezing temperature. They are more affordable than glazed.
This generates power from gas or propane. It heats water by passing it through a combustion chamber; the chamber burns gas while warming the coils made of copper. When the water passes through these coils it gets warm as it returns to the pool. If the gas or propane is cheap in your area this can be a good value for your money because the operating cost will be cheaper.
Other Factors to Consider
Another important factor to consider would be advanced features such as the climate where you live in.
All the types of heating system that we have mentioned are important but you have to factor in the climate in your area. These heating system that we have mentioned are all effective but they have limitations. For example, solar panels are more effective in places where you get a lot of sunlight, and while it is very effective on another season where you can get ample sunlight, during long harsh winters, perhaps you might need a backup heating system so you can continue to enjoy a warm dip in your swimming pool. It is also very important to place solar panels strategically to reap the full benefits of it or it will just be a waste of money.
Another example of limitations are gas heaters, they are not as effective in heating water during the harsh winter season. So if you are from places with really long and freezing winters, you have to choose a different and more effective heating system.
It's no shock that pool heaters don't exactly come cheap. Perhaps you are going to share the cost with a neighbor or maybe you'll just be the most popular guy when winter starts creeping in. For this reason, the portability of the unit is important. Most of these units are easy to set up, install, and use. Having the ability to load up the heater and bring it with you is life changing.
We should remind you to always check out the power source and voltage of the pool where you plan to bring it. If the pool and heater are not compatible, you will have just loaded up your 200-pound machine for no reason.
Frequently Asked Questions
q: Do solar panel heaters work at night?
With a sufficient sized panel, it can store enough heat to sustain your swimming pool even though at night the solar panel can’t generate power anymore. This is assuming that your solar panels are sized correctly for your pool. Ideally, the surface area of your solar panels should match the size of your pool. It is possible to have less/smaller panels but the heating process will be slower.
q: Can I install the unit by myself?
Typically, yes. Most systems are made to be user-friendly and very easy to install. Solar panels are known to be the easiest to install, assuming you have already considered where you will place them and how the sun hits your house. However, if the unit is not installed by a professional it may affect the warranty. So it is better to check your warranty limitations first.
Another reason that you may want to leave it to the professionals is the ease of mind of knowing that the machine will be running at its highest efficiency and that it will be safe. There are very strict guidelines to follow and knowing that you and your children will be safe around the machine is priceless.
q: Should I use a pool heater in conjunction with a pool cover?
Great idea! A pool cover is a great addition to work side by side with your pool heater. Not only will the cover keep your pool clean, if you cover the pool when you are not using it, but the heat that you have pumped in will also have a much more difficult time evaporating. Overall, a pool cover will help to lower your electricity bill because you will have fewer degrees to conquer and as such, you will also not need to run the heater as often nor for as long.
q: What is a BTU?
BTU is short for British Thermal Unit. The term is used in for air conditioning units and heaters. BTUs measure how much energy is required to heat one pound of water by one degree Fahrenheit. For the most part, you can use the number of BTUs and multiply that by ten to determine how many gallons of water the machine will successfully heat.
q: Are these units safe to use while swimming in the pool?
Yes, it is safe to use a pool heater while you are swimming. The device is not actually in the pool with you, preventing danger. However, it is recommended to run the pump either regularly or at least for 6 hours before you plan on swimming. This will help to keep your electricity bills lower and also be easier on the pool heater itself. You can imagine how much warm air is pushed out of your air vents when warming the house, now imagine how much more you need to warm an entire body of water.
