Solar Swimming Pool Heater: Pros and Cons

Solar swimming pool heaters are great examples of energy efficient and eco-friendly alternatives to electric models. These appliances use light and heat from the sun to warm up large quantities of water in swimming pools. Solar swimming pool heaters are very popular in different parts of the world. Below are some of the pros and cons of using solar swimming pool heaters.


Low cost of operation is a primary advantage of solar swimming pool heaters. When you use these devices, you are no longer dependent on conventional heating methods such as electricity, gas or fuel. You can achieve significant savings by heating up your pool water for free. Swimming pools are usually warmed up during peak time, when electricity costs are highest. By eliminating this expense, you can save hundreds of dollars a year.

Another major advantage is that you can do your part in saving the environment. The use of gas for heating purposes results in the emanation of carbon monoxide and other toxic elements. It also contributes to the depletion of the ozone layer on earth. Though electricity is clean to use, it is produced by burning fossil fuels, which makes it just as bad a choice. In contrast, solar swimming pool heaters use the limitless energy from the sun and are the best choice for the environment.

Solar swimming pool heaters work by heating up water and transmitting it to the pool by means of the existing pool pump. The water in the pool is transmitted back and forth by means of the pump. In most cases, you do not have to spend extra money on getting a new pool pump or other equipment. Most solar pool heaters work with the existing pool equipment. Another advantage of solar pool heaters is that you can enjoy your swimming pool for much longer periods of time. This is especially true in colder climates, where most people have to close down their pools in the fall.

With the use of a solar pool heater, you can open your pool earlier in the spring and close it later in the fall. You can maximize the use of the pool on cool but sunny days. You can use insulated pool covers to maximize heat retention in the pool as well.


A solar swimming pool heater is dependent on the sun for operation. On cool or windy days, it will not give you best results. However, a solution for this problem is to use a solar pool heater in conjunction with a gas or electric heater. This way, if you do feel like a swim on a cool, cloudy day, you can still warm up the pool.

Solar swimming pool heaters can be quite expensive to purchase and install. Depending on the size of the pool, they can take up a considerable portion of your roof. However, over time, these appliances pay for themselves many times over. Another common complaint is that solar swimming pool heaters do not heat up the water as well as electric or gas heaters. However, in most cases, the use of solar power makes the water in a swimming pool pleasantly warm, which is suitable to most people.
