Abstract
A resilient black flexible polymer mat is submerged on the bottom of a small pool or pond to promote the passive solar heating of the water. The upper surface is non-reflective, textured and provided with projecting elements to increase the surface area for enhancing the amount of solar radiation absorbed to heat the mat; the bottom surface has a plurality of spaced-apart projecting frictional supporting members to assist in retaining the mat in position on the bottom of the pool or pond; spaced-apart passages extending between the upper and bottom surfaces permit the movement of water.
Claims17
An accessory for promoting the passive solar heating of a pool or pond, the accessory comprising a resilient black or dark-colored flexible polymer mat, the polymer being chemical-resistant and having a specific gravity greater than one,
- the mat having an upper surface and a bottom surface,
- the upper surface being non-reflective and textured to increase the absorption of the IR rays of the sun to heat the mat when it is placed in the water of a pool or pond,
- the bottom surface having a plurality of spaced-apart projecting frictional supporting members to assist in retaining the mat in a submerged position on the bottom of the pool or pond, and
- a plurality of spaced-apart passages extending between the upper and bottom surfaces.
