Why You Need a Pool Cover

Evaporating water eats up huge amounts of energy. It only takes one Btu (British thermal unit) to raise a pound of water one degree. However, every pound of 80 F water that evaporates removes 1,048 Btus of heat from the pool.

All this depends on the pool's temperature, air temperature and humidity, and wind speed. The higher the pool temperature and wind speed and the lower the humidity, the bigger the evaporation rate. Adding a windbreak like trees, shrubs or a fence can reduce evaporation. But this has to be high and close to the pool so it won't cause turbulence over the pool that increases evaporation. Another thing to remember is don't let the windbreak shade the pool from the sun which heats it.

To minimize evaporation, the use of a pool cover is advised. This can greatly reduce heating costs and save you a lot of money. Thus, you get to enjoy warm water that's good for swimming even on the next day. This is because a pool cover minimizes heat loss that occurs overnight when temperatures go down.

It also keeps out leaves, twigs and other debris. Without a pool cover, anything can land on your pool - dog toys, dead insects or dirty leaves. Unless you enjoy fishing for these items, use a pool cover so you won't be running after every leaf that goes there.

With a good cover, it's easy to maintain your swimming pool. You'll vacuum less often and spend more time swimming. That means you'll enjoy your pool more and spend less time cleaning it.
