Abstract
Conservation of energy of a swimming pool is provided by an attractively colored polyethylene panel secured to a circular frame which panel cover and frame are stable, and will not disintegrate due to direct rays of the sun. The panel passes and traps the heat of the sun rays during the day and maintains a pool cover to prevent substantial loss of heat and thereby retain the heat of the pool. The absorption of heat and reduction of evaporation is effective primarily to reduce fuel of the pool heater and also reduces consumption of chemicals and water.
