How to take advantage of solar energy to heat swimming pool water

Anyone who has a swimming pool and can’t and won’t afford to heat it at the cost of increasing energy consumption, is likely to start looking at it with anticipatory nostalgia when temperatures start to drop in thermometers. However, there are clean alternatives available. Taking advantage of solar energy to heat swimming pool water is not only one of them, but it is “The most profitable use of solar energy” in a multitude of climates, depending on Ministry of Energy the United States. For this reason, we will tell you how these solar thermal energy systems work, what types there are and what are the main components of solar kits for swimming pool water heating.

How to keep pool water warm with the sun.

In the same way that it can harness energy to light a house, power a computer or irrigate the ground, solar energy can be used to heat pool water when the ambient temperature is no longer favorable. a bath. In fact, its potential for this domestic use is such that, depending on the size and type of installation, it will keep the water between five and ten degrees above room temperature.

In order to extend the bathing season without this translating into an increased demand for energy from non-renewable sources, the panels will be the fundamental part. This is valid both for systems which heat water directly, in which it circulates freely through the panel, and for indirect solar installations. This more expensive modality is one of the most widely used, because it offers superior performance.

Solar kit to heat the pool water.

In general, solar systems used for this purpose must incorporate, at a minimum, the following elements:

  • Solar collectors. In addition to capturing the sun’s energy, water will flow through them so that it can be heated and returned to the pool.
  • A bomb. It will be essential that the water circulates from the pool to the system.
  • Filters. With them you will make sure that the water returning to the pool is free of debris.

How to calculate the size of the solar installation.

This is one of the decisive points for making good use of the sun’s energy to heat water and to do so at an affordable cost. The reason is clear. The more panels, the greater the investment. However, failing will mean not achieving the desired goal, so correctly calculating the number of solar panels required will be crucial.

One aspect that makes the decision difficult is that there is no exact formula. The size of the installation depends on so many aspects that generalization is practically impossible. The climate of the area where you live and the hours of sun exposure in your home are two of the determining factors. With this, the usual thing is that the dimension of the solar installation is the equivalent to between 50% and 100% of the pool size heat.

However, as mentioned, what may be worth in Almería will not be the same as in Vigo, so it will be necessary to polish well before this decision. Another important one will be the type of solar installation chosen, which includes collectors without cover and those who have. While the first family is distinguished by its lower cost, the second does so for greater efficiency in heat capture. Again, the specific case of each individual will determine which system is the most practical.

Either way, the truth is, this type of solution is an option to consider for clean energy home use. The savings it entails, as well as its low maintenance cost, are some of the advantages of this alternative, which also makes it possible to move towards less dependence on energy from fossil fuels.
