To begin with, solar systems for heating water in the swimming pool will easily save your money. This means that your swimming pool may be heated rather cheaply and efficiently in this way, with energy conservation. Here is the word about solar systems which are very cheap and can be placed independently. What will ensure that the water in the swimming pool is clean is the pump. It is used for filtering. However, water in the swimming pool will use this solar system to circulate through the collectors. Solar system for heating water is a low – cost one Everything mentioned above underlines that the system is rather a low-cost one. Similarly, it is one of the simplest systems for solar energy which exists. Nowadays, people in different part of the world have this system installed. They are rather satisfied because of its great characteristics. Of course, when you build up something it is important to be efficient and to perform its function in the best way. That is why solar systems for heating water in the swimming pool are highly recommendable. Covers for the swimming pools First of all, one should have a cover for the swimming pool. Needless to say, this cover is both the most effective and safest thing which can be used to reduce the cost of swimming pool heating. If one makes the entire system without the cover, there will be more evaporation of water. Besides all that swimming pool covers will allow better absorption of solar. Rings for the swimming pools Some people use so called ‘rings’ which are several meters in their diameter big. You need a couple of rings to succeed in covering greater part of the surface of the water in the pool, almost 80%. Although these rings are less effective than covers, it is good to have them if one does not have other solution. What are solar collectors? To begin with, the water from the swimming pool is pumped through a filter. After that, it is pumped through the solar collector. It is heated before returned to the swimming pool. There is a difference between solar collectors for heating swimming pools in hot and cold weather conditions. When installing solar pool heating we have to think about the characteristics of the roof, because they may have great effect. In countries with the hot climate, solar collector may have different usage. It can be used to cool the swimming pool in summer. How this happens? Well, water may circulate through the collector at night. What is important is that when installed solar collectors have to be placed to grasp the maximum of solar energy in a daily level, or in a longer period of time, such as season. Scientists claim that the best position of solar collectors in the places in the northern hemisphere is towards the south. But, what happens these days is that inclination and the location of the collector are very important. It can be rotated and moved under 45° C the east or west of the southern point and its performance will not be reduced. An alternative to solar heating is using gas pool heaters which are also a cheap an effective way to keep your pool heated. Filtered water simply bypasses the solar collector in just one cast. It is when the temperature of the collector is similar to those of the swimming pool happens something different. After that, water is returned to the swimming pool.
