How quickly does your pool empty out?
There are various contributing factors that contribute to water loss.
- Evaporation by the solar radiation (by the heat of the sun)
- Air Temperature
- Pool Chemicals
- Pool Usage
- Pool Backwash & Rinse Cycles
The below water evaporation rate table indicates the evaporation rate in liters per hour of an unoccupied standard 8 x 4 meter swimming pool at given pool water temperatures, air temperatures, and also percentages of humidity. These are average temperatures that can be expected throughout South Africa during most of the summer, spring and autumn.
|EVAPORATION RATE (litres per hour) FROM 8 x 4 METER POOL, UNOCCUPIED, NO WIND|
These humidity rates and the table above is info taken from the source here, are about what you’d expect in Sydney, Melbourne, Brisbane. These are similar to much of South Africa. Often humidity can be 70% in these areas too.
Fact: Did you know that an average heated swimming pool in will lose almost twice it’s volume of water every year from evaporation. In the hotter areas of the country it is even more severe. An average heated 8 x 4m pool will lose almost 80,000 litres of water each year if it’s heated year round.
If you calculate how much this costs according to the level 3 water restrictions, this will cost you a fair amount.
To prevent this huge water loss we have a SOLUTION – Get A Pool Cover. This reduces water evaporation & loss by up to 97%
