Sunlight allows not only life on the planet Earth, but at the same time we have learned to use it successfully. Sunshine and intensity of radiation depend on the season, the weather conditions and, of course, the geographical location. And if we learn to work with these variables, solar energy can be used as an ideal source.

 

 

It is a device that converts solar radiation to heat. The solar collector contains so-called solar radiation absorbers, which can absorb the radiation and convert it to heat. This heat passes the medium through the medium that is transferred to the point of use. The medium can be air, oil, salt, but most often water. It is used for solar heating of swimming pools or solar showers.

 

Solar absorbers for pool water heating are the simplest type of solar heating. It is basically a simple, black, plastic tube that absorbs sunlight thanks to its dark color. Across these absorbers flows the pool water, which is warm and warmer, returns to the pool. Water to solar heating is pumped through the pump. Simple regulation can then ensure that the water starts to draw when the solar heating can actually heat it.

 

For the production of solar collectors, it is necessary to use materials that do not degrade in the sun and are highly resistant to UV radiation. Polyethylene (PE), polypropylene (PP) and ethylene propylene diene monomer (EDPM) have proven to be of production. Solar pool heaters are produced either as panels or as pyramids. In both types, it is possible to connect multiple heating in series to multiply their functions.

 

1 m2 of pool area requires at least 0.5 m2 of solar heating area. Heat savings can also be ensured by covering the pool with a solar sail at the time we do not use the pool.
