Heating swimming pools

The pools contain large bodies of water maintained at a controlled temperature, it varies by what type of activities that must take place in the pool and the degree of comfort desired

Water temperatures for different types of pool

Temperature ° Cswimming competitions 22-24

Light sport / leisure 24-28children's pool / warm 28-30

pool for therapeutic use 29-30

In the heating of swimming pools, there are two different parts: development and maintenance regime. The development scheme is the increase of water temperature from the value of the aqueduct to the value of use.

This takes place during the first start of the pool and then whenever it is necessary to empty the tank for routine maintenance and hygiene.

This time can varies from 24 hours up to 96 h.Once you reach the desired temperature, it must be maintained so we need to provide a continuous heat input equal to the sum of the losses of the entire pool: this is the maintenance phase.

Heating times

The heat loss of the poolsThe heat loss of a swimming pool are due to several factors:

• evaporation from the surface of the water;

• radiation to the outside;• convection produced by

the contact between air and water;

• transmission through the walls of the basin;daily change of water flow.

The most important item is the evaporation and dispersion depends on the size of the water, the water temperature and above the air temperature and its vapor content.

Solar heating for swimming pool water

Solar heating is an economical solution to heat the pool water.It is ecological, economical, and versatile
