The Different Types of Pool Heaters
Before we talk about the specific products we can recommend, let’s first look at the different types of pool heating methods available, as well as their respective pros and cons. This will make it easier to narrow down the choices for a top-rated pool heater.
Gas Pool Heaters
It is the traditional choice when it comes to home heating. It works in the same way as the gas water heaters you have in your shower. There is a combustion chamber and gas burns inside it. Heat passes through the copper coils, and in turn, this increases the temperature of water in the pool.
If you prefer to use gas pool heaters, there are two main options – natural gas or propane. Regardless of which one you choose, they are both known for being efficient. They heat the water quickly.
If you decide to go for this type of heating method, one of the most important is to choose one that is labeled as Low NOx, which is good for the environment. They have been tested by third-party agencies and proven to emit low emissions while heating the pool quickly.
- Quickly heats water in the pool
- Low initial cost
- Low emissions
- Expensive to use in the long run
- Lifespan can be short
Electric Pool Heaters
If you are looking for an eco-friendly alternative to gas, consider electric pool heaters. They take advantage of ambient temperature to make the water hot. Since there is no need to connect it to a gas line, the installation is also more straightforward.
The use of electric heaters is best only for small pools. It is not as powerful as its gas-powered counterparts. Therefore, when you use it for a large pool, it may end up being power-hungry, or worse, unable to heat the water at all.
- Easy to install
- Lasts through the years
- Low initial cost
- Best only for small pools or tubs
- Heats water slowly
Solar Pool Heaters
From the three types that are mentioned in this article, this is the best if you are looking for an eco-friendly option. It uses the energy of the sun, which is a renewable resource. The initial costs can be steep, but in the long run, the savings will be worth every dollar.
There are different types of solar pool heaters. However, if you have a large pool, the best ones are solar panels and solar blankets. Solar rings and domes may not be as powerful. Also, if you live in an area where the sun does not always shine, using solar heaters is not recommended.
If you are using solar panels for pool heating, you will have two main choices. The first one is an unglazed collector which comes with plastic or rubber panels. The second is a glazed collector that comes with copper tubing laid on an aluminum plate.
- Uses renewable energy
- Can last up to 20 years
- Inexpensive to operate
- High initial cost
- Needs a lot of direct sunlight
Choosing the Best Pool Heater
To help you narrow down the possibilities, this section talks about some of the most important factors you need to take into consideration.
Consider the Size of the Pool
One of the first things that you need to do is to consider the size of the pool. If it is large, obviously, you will need a more powerful pool heater. Otherwise, it will not deliver the heating requirements and may be ineffective. In some cases, especially if you opt for a solar heater, there is an option to combine multiple units for better heating performance. If the pool is small, however, you don’t need a powerful heater as you will just end up wasting energy.
Consider the Type of the Pool
Aside from the size, the type of swimming pool that you have is another crucial consideration. If you have an above ground swimming pool, you don’t need a heater with high power. You are good with most standard heaters, including the ones that are solar-powered. On the other hand, if you have an in-ground pool, especially if it is large, you will need a more powerful heater. In this case, most people opt for electric or gas pool heaters compared to their solar counterparts.
Identify the Heating Requirements of the Pool
After determining the size and type of the pool, you can now determine the heating requirements. With this, one of the most important considerations is the BTU of the heater. BTU stands for British Thermal Units. The higher the number, the more powerful the unit is. However, you don’t always need a high BTU especially if you only have a small swimming pool and if it does not get extremely cold from where you live. In the case of some models, especially the electric ones, the rating is based on horsepower or HP. A higher rating also corresponds to better heating performance.
Consider Ease of Installation and Operation
In most cases, you can install the heater on your own, especially if it is solar. Gas heaters, on the other hand, can be complicated. While the manufacturer provides detailed instructions on how to complete the installation, especially for novices, it can be an intimidating experience. Pay attention to what the manufacturer says. Some models require installation only by licensed technicians. If you fail to meet this requirement, the warranty will end up being invalid.
Aside from the effortless installation of the pool heater, it is also best to choose one that is straightforward to operate. It should have an easy-to-see display so that you can easily monitor the temperature. It should also be easy to set the temperature as you desire.
Consider Care and Maintenance
It is a burden to the owner of the unit if it requires a lot in terms of care and maintenance. Look for a pool heater that is effortless to clean. If you don’t pay attention to taking care of the heater, this can compromise the performance of the unit. Regular inspection of the heater is important. If there is any problem, deal with it as soon as possible. Otherwise, it only gets worse and can be costlier to repair.
Evaluate the Noise
As you try to decide which heater is best of your swimming pool, you must evaluate its noise. It is annoying to spend time in the pool while hearing a loud noise from the heater. One thing that makes the heater quiet is the case. This provides insulation from loud noise. If you are looking for a quiet pool heater, solar and electric heaters are two of the best options. Gas tends to be noisier than the two, although, the latter is the better option if power is a more important consideration than noise.
Decide Based on Climate
Another excellent way to narrow down your choices is to consider the climate from where you live. Some models of pool heaters rely on ambient temperature to heat water in the swimming pool. If you are using solar heaters, on the other hand, you need the sun to capture the energy needed by the heater to warm water in the pool. The climate in your place will also dictate the energy requirements and heating performance of the pool heater.
Go Beyond Price
It is tempting to choose one product only because it is cheap. However, that should not be the case if you want a high-performing swimming pool heater. Be ready to spend more if performance is more important compared to price. It will be worth every dollar. To be sure, read reviews and learn from the real-life experiences of other people so that your money will not go to waste.
Look for a Pool Heater with Extended Warranty
This is important if you want to have peace of mind. Most products come with a standard one-year warranty. However, because the lifespan of pool heaters should be more than one year, it is best to choose one that comes with longer warranty coverage. Within this period, it is covered under defects. The manufacturer will provide not only free repairs but also a free replacement of defective parts. It is important to read the terms and conditions from the manufacturer to prevent the warranty from being void.
How to Make the Most Out of Your Pool Heater
Before we conclude this short buying guide, allow us to leave you with some tips on how to maximize the benefits of your pool heater.
- Pay attention to its proper installation. The failure to follow the instructions from the manufacturer can lead to inefficient performance of the heater.
- It is not enough that you have a reliable pool heater. It also helps to ensure the chemical balance in the water. Otherwise, the swimming pool will be unhealthy. Worse, it can also cause external damages to the heater, including rust and corrosion.
- Regularly inspect the casing of the heater. Any visible damage can speed up the wear and affect heating performance. There is also a higher risk of electric shock if the heater has visible damages.
- If you are unsure of how to complete the installation, it is best to leave the job to the pros. They know better. Also, as earlier mentioned, the warranty may be rendered invalid if you do not hire a licensed technician to install the pool heater.
