A combination of a floating thermal pool cover and thermal pool cover retaining device having a flexible clamping portion for clinging to an extended edge of a pool and a retaining portion for maintaining the floating thermal pool cover in direct contact with the water surface area of a pool. By keeping the floating thermal pool cover in contact with the water surface area of the pool, the pool water is heated more quickly and the amount of debris which falls into the pool is minimized.
