12 Best Pool Heaters Of 2022: With Detailed Reviews & Buying Guides

Certainly, even the most tolerant of cold will find it difficult to feel comfortable if soaked for too long in a too cold lake. While a dip in a lake offers many benefits, the temperature difference, especially during times like autumn or winter, will negate these benefits.

Instead, the cold can bring discomfort and many diseases related to the respiratory system. So if you do not want to face these unpleasant problems, equipping the best pool heaters for your pool is extremely necessary to warm and keep the temperature stable.

In fact, pool heaters are not an easy tool to choose from because of many different factors, so I will help you get the information you need to determine which is the most suitable product easily.


Types

Although you may think that all pool heaters are the same at first glance, we can classify these products into many different groups to easily review and make appropriate judgments. It is also important to note that there are many ways to organize these heaters. However, in today's article, I will use the most common classification through the type of energy consumed by the device to conduct analysis and evaluation.

Gas or Propane

Whether on land or in a lake, heaters using gas or propane are still very popular today.

Because the water-warming efficiency of these fossil fuels is often very high, and the ability to keep warming is stable even when the surrounding environment has many adverse developments.

In other words, if you use fuel to burn, you will not need to care too much about external factors anymore. Still, there are a few other important factors to keep in mind.

Thanks to the impressive features available, a fuel-burning heater will be a good choice for areas with average annual temperatures of about 50 degrees Fahrenheit. Under these conditions, the water-warming performance is good.

This line of pool heaters will maximize efficiency and minimize waste. In addition, you also need to pay attention to the warranty and installation of these devices.

Electric

The electric pool heater is an upgraded version of pool heaters using gas or propane. Because if using electricity, the risk of fire and explosion will be greatly reduced. The cost of energy will also be much cheaper because, inherently, the cost of these types of energy has a large difference.

In addition, the advantages of fuel-burning heaters, electric-operated pool heaters also possess almost everything from maintaining heat stability to no dependence on the external environment. However, electric machines need to spend 3 to 4 times more expensive than gas-consuming devices. And with large pools, installing electrical systems is a big challenge.

Solar

With the exploitation of energy from nature, specifically, heat from the sun, you will not need to worry about problems such as adding more reserves or finding a power source like electric pool heaters, gas or propane.

These pool heaters are also quite environmentally friendly as they do not directly or indirectly produce emissions during operation. Thereby minimizing negative impacts on the environment.

Solar panels work by pumping pool water into a solar hot water collector that can be mounted on the roof or the ground.

Here, the panels made from heat-retaining materials have collected heat from the sun, then transferred to metal tubes or rods capable of transferring heat, and finally, the water stream will receive heat when passing through.

Because the structure is heavily dependent on the environment, if the weather is too harsh, the product's ability will also decrease quite a lot.

Buying Guides

Don't skip my guidelines below if you don't want to get too confused during the selection process, and consider which pool heaters are best for you.

It is because we will have to choose between many factors to find the factors that have the most important influence on the performance and quality of the product. And of course, this process is not easy if you do not have enough experience.

Pool Size

Like the fireplace that we often use in our apartments, the size of the pool heaters has a great relationship with the pool. And that's why you will need to carefully consider both length, width, and depth to assess what size heater we need to equip accurately.

As a rule, a larger pool will hold more gallons of water than a smaller pool. The more water, the larger the size of the pool heaters must be to generate enough heat to maintain and increase the water temperature before the convection of the environment occurs, and the water cools down.

The larger the size, the more energy the device consumes, which leads to greater pressure to pay, especially when we use natural gases.

The performance of large-size products is often high and puts a lot of stress on the parts, which eventually leads to a significant shortening of the part's life. So not always the larger the product, the better the quality. But instead, devices with dimensions that correlate with the size of the tank will be the best choice.

Output Performance (BTU)

One parameter that is certain that any model of pool heaters will provide to users is the number of BTUs that product can generate. If you don't know, BTU (British Thermal Unit) is the unit of energy required to raise the temperature of 1 pound of water by 1 degree F.

And the average BTU level that most products are on the market today. The school currently owns between 15,000 and 80,000 BTU. Some special types of equipment can reach 90,000 BTU or more, like the Hayward W3HP21004T.

In general, choosing a product with BTU is not unreasonable because I am sure that all of us want the pool to warm up quickly and for the longest time. However, even if you can afford it, using a product that is too high-performance will be somewhat wasteful. Instead, we need a standard formula to calculate the most reasonable number. Here multiply the pool's water capacity in gallons by the weight of one gallon of water (8.3 pounds), and the answer is BTU.

Operating Costs

In the analysis of the types of pool heaters above, I mentioned the energy consumption of 3 main product lines based on gas, electricity, and solar energy. And the energy factor is also central to determining whether a product has high operating costs.

If ranked by cost consumption based on operating time, gas or gas is the product with the highest cost, followed by electricity and, finally, solar energy like Intex Solar Heater Mat.

If considered carefully, gas products will not require too high installation costs, but the price of fuel will become more expensive over time. Meanwhile, electric pool heaters, with performance equivalent to gas products, have high installation costs. And finally, solar-powered products, though not very efficient, are very cheap.

Based on these characteristics, we can conclude that each model has its advantages and disadvantages related to operating costs. Depending on the needs, we choose the most suitable product. But there is no way to assume that one type of pool heater can be more economical than others.


FAQs

How long does it take to heat up a medium-sized pool?

First, we will need to agree on the size of an average swimming pool, from the smallest 10,000 to the largest 20,000 gallons of water. In addition, it is not possible to eliminate all factors from the outside environment, such as temperature, weather, and even altitude. If all of the above factors are considered, within 24 hours at most, a medium-sized pool will raise the temperature to an appropriate level. Typical electric or gas-powered pool heaters like Hayward W3H250FDN can do this job within 12 hours.

Is it better to leave the pool heater on all night?

The best advice for you is not to leave your pool heater on overnight. Because this action is useless and only adds to the cost, you have to pay for heating the lake.

What time of day should I run my pool heater?

The right time for you to use pool heaters does not have too much to do with environmental conditions, but instead, you need to remember to turn on the machine a few hours before you start using the pool.


Conclusion

After reading today's article, I hope you have gained the necessary information and knowledge to choose the best pool heaters model that best suits your needs.
