Public pools consume large amounts of energy. Italian operators/owners spend millions of euros every year to heat their pools. Much of this energy is often wasted and it can be saved with proper management. This waste, indeed, also contributes to the increase of greenhouse gases in the atmosphere.
Public swimming pools consume large quantities of energy. Facility owners/managers spend millions of euros every year to heat their pools. A large portion of this energy is often wasted but this can be avoided with correct management. This waste also contributes to the increasing greenhouse effect in our atmosphere. According to the American Department of Energy’s EERE (Energy Efficiency and Renewable Energy) you need 0.001163 kW/h of energy to raise one liter of water by 1°, whilst every liter of water at 27° that evaporates wastes 1.218 kWh of energy.
A heat retention cover allows total blockage of water evaporation and therefore less heat loss. In order for the cover to work properly, and for you to benefit from the significant energy-saving advantages, it is recommended that you always cover the pool at night and when not in use, regardless of whether it is an indoor pool or an outdoor one.
The degree of evaporation in an outdoor pool varies according to different factors: water temperature, air temperature, humidity, and wind speed. The higher the water temperature and wind speed, and the lower the humidity, the larger amount of evaporation you'll have. The temperature fluctuations between day and night also cause a drastic decrease in water temperature.
Indoor pools are not subject to the same temperature fluctuations that are typical in outdoor pools, but, even though they are not influenced by wind that helps dissipate heat, they require ventilation installation to control the internal humidity levels caused by evaporation. Without an adequate ventilation system, the high levels of internal humidity cause numerous problems, including condensation on cold surfaces that irreplaceably damages structural components. The energy necessary to manage an adequate ventilation system is added to the already high costs of normal pool functioning. Furthermore, ventilated air needs to be cooled, which means even higher costs.
Lower management costs
A heat retention cover can provide an average 35-40% reduction in running costs per year, due not only to the blockage of evaporation but also to other advantages provided by heat retention covers:
– A dramatic decrease in the cost for water heating;
– 30-50% decrease in necessary water top-ups;
– 35-60% decrease in the need for chemical products;
– No need for dehumidifying and vacuum systems overnight;
– Greater hygiene and cleanliness.
