Save Energy with ThermGard Pool Covers

The natural loss of heat accounts for more than 70% of all heat lost from both indoor and outdoor pools. When the air temperature drops below your pools temperature, water evaporates from the surface of the pool theoretically until the water is the same temperature as the air. For heated swimming pools this means that your swimming pool heater will have to be engaged more frequently in order to maintain the desired temperature of the pool. This results in higher consumption of energy as well as higher costs for the aquatic facility.
It only takes 1 BTU to raise 1 pound of water 1 degree, but each pound of 80° water that evaporates from a pool causes a loss of 1048 BTUs of heat energy.
