A solar pool heater is a device that uses the sun’s energy to heat your swimming pool. It consists of an insulated, black tank filled with water and a special type of plastic pipe called “black tubing” which absorbs sunlight. The system works by circulating warm water from the storage tank through the black tube where it heats up before returning back into the storage tank for use in heating your pool or spa.

Solar Pool Heater: Frequently asked questions

What types of Solar Pool Heater are there and what determines a good product?

There are two types of solar pool heaters, active and passive. Active systems use a pump to circulate the water through your system while passive systems rely on gravity alone to move the water from one part of the pool to another.

A good solar pool heater is one that can heat the water to a temperature you desire. The higher the temperature, the more efficient it will be at heating your pool. It should also be easy to install and maintain so you don’t have any problems with it later on down the road.

Who should use a Solar Pool Heater?

Any pool owner who wants to extend their swimming season. A solar pool heater is a great way to heat your water and save money on energy costs at the same time.

Based on what criteria should you buy a Solar Pool Heater?

There are two main factors to consider when buying a solar pool heater. The first is the size of your swimming pool and how much heat you need to maintain it at an ideal temperature all year round. The second is whether or not you want a system that requires minimal maintenance, as well as one that can be easily installed by yourself without having to call in professional help.

There are many factors you should consider when comparing a Solar Pool Heater. You need to look at the price, features, and other specifications of each product carefully before selecting one.

What are the advantages and disadvantages of a Solar Pool Heater?


A solar pool heater is a great way to heat your swimming pool. It can be used as an alternative or supplement to other types of heating systems and it will help you save money on energy bills in the long run. The main advantage of using a solar panel for this purpose is that they are environmentally friendly, which means that there are no harmful emissions released into the atmosphere when you use them. They also do not require any additional equipment such as pumps or filters because they work by absorbing sunlight directly through their panels and then converting it into heat energy before releasing it back out again at night time so that your water remains warm all day long without having to rely on electricity from the grid during peak hours where prices tend to be higher than usual due to increased demand for power usage around these times. This makes them ideal if you want something more cost effective but still reliable enough for everyday use while saving yourself some extra cash over time compared with what would otherwise have been spent paying off expensive utility bills every month instead.


The main disadvantage of a solar pool heater is that it can be expensive to install. It also requires maintenance and most importantly, you need sun. If the weather isn’t sunny enough for an extended period of time your pool will not heat up as much as you would like. However, if installed properly this shouldn’t happen too often.
