SOLAR POOL COVERS
Keep in mind that a Thermal Pool Cover is recommended for all pool heating systems. Heating a pool without a cover is like heating a house without a roof...the heat just goes right out the top.
Without a pool cover, the cost of operating a Heat Pump or Gas Heater is doubled, and a Solar Heater's effectiveness is decreased. For convenience a roller may be added to ease placement and removal of the cover. If a pool cover is not to be used, the size of the heater must be increased by 75% - 100%. Pool covers range in cost from $60 to $130 for residential pools; rollers start at $185.
