The primary deciding factor for losses and gains is the pool surface and, to a lesser extent, the pool shell
insulation to the soil. The volume is decisive for calculating temperature changes.
The pool measurements are entered directly for round and free-form pools and via length and width for
rectangular pools. The mean depth of the water is determined from this information. In free-form pools,
the longest length of the pool is used for approximate determination of the pool geometry.
The maximum swimming pool temperature defines the temperature up to which the pool can be heated
by solar power, and must always be higher than the desired temperature. A high maximum temperature
allows longer operating periods of the collector loop, by definition increasing the swimming pool heating
requirements and the solar fraction. The control of the auxiliary heating ensures that the pool is
regulated with a hysteresis of 0.5 Kelvin.
Outdoor pools
The other fields are only relevant and can therefore only be completed for outdoor pools.
The color of tiles defines the absorption of solar irradiation on the pool wall and therefore how much of
the irradiated energy onto the pool surface can be used to heat the pool water.
The prevailing wind speed is decisive for the convection and evaporation losses and therefore for total
losses. Wind speeds are supplied with the climate file for the location. Define the geographical location
of the swimming pool in its geographical environment, e.g. in a wooded area, a residential estate, or in
the open. Enter whether windshields are available at the pool which can reduce convection and
evaporation losses.
