DIMENSIONING

HEATING SWIMMING POOLS
Heating a swimming pool using solar collectors is advantageous especially if combined with the combi
system, as this allows effi
cient disposal of the excess summer heat captured by the solar panels. The
dimensioning of these systems, however, is not trivial due to the many factors that cause heat losses from
the swimming pool. Both in indoor and outdoor swimming pools the main cause of heat loss is evaporation.
This is aff ected by the temperature of the water and humidity of the air and wind speed on the surface.
It is therefore clear that heat loss in outdoor pools depends greatly on the geographical area where they
are installed. It is also not possible to guarantee a determined constant temperature of the water for the
diff erent months.
The fi gure below summarises the diff erent percentages if heat loss from outdoor and indoor pools.
Heat loss in the outdoor swimming pool
Heat loss in the indoor swimming pool
A = Evaporation
B = Radiation towards the sky
C = Loss towards the ground or other
A = Evaporation
B = Ventilation
C = Other
The use of a cover on the pool, when it is not being used, greatly reduces heat loss due to evaporation.
Regarding the dimensioning of the solar collectors, this can only be carried out approximately and on the
basis of the surface of the pool.
The following table supplies the indications for dimensioning of the collectors on the basis of the type of
swimming pool, with water temperature of 26°C.
However, the exact calculation must always be carried out by a heating technician and the swimming pool
must be heated with the aid of a boiler in order to be used not only in the summer months.
