Water evaporates consuming large amounts of energy. It only takes one Btu (British thermal unit) to raise one pound of water one degree. However, every pound 80 F water that evaporates removing heat from 1,048 BTU.
All this depends on the temperature, the pool temperature and air humidity, and wind speed. The higher the pool temperature and wind speed and low humidity, the greater the evaporation rate. Adding windbreaks such as trees, shrubs or fences can reduce evaporation. One thing to remember does not let the windshield shade the pool from the sun that heats it. You can buy custom retractable pool enclosures for indoor outdoor pools from various online sources.
To minimize evaporation, the use of a swimming pool cover is recommended. This can greatly reduce heating costs and save a lot of money. Thus, you can enjoy good warm water for swimming even on the next day. This is because the pool cover minimizes heat loss occurring when the temperature drops overnight.
It also keeps out leaves, twigs, and other debris. Without a pool cover, anything can land on your pool – toy dog, dead insects, or leaves that are dirty. Unless you enjoy fishing for this item, using the cover of the pool so you will not run after every leaf that goes there.
Good cover, easy to maintain your swimming pool. You will vacuum less often and spent more time swimming. That means you'll enjoy your pool more and spend less time cleaning it.
