Personally, I disagree with the logic used by those above. If the bubbles are up, there will be larger surface area to absorb the sun's heat. Increased levels of heat absorption seems more important than the rate of heat transfer, especially when considering the fact that heat transfer takes place almost instantaniously.****i have tried it both ways, bubbles up or down. makes little or no difference heating. with bubbles down, though, it is easier to clean debrie off the cover and keep it clean.
The bubbles go face down on the solar cover because when the sun hits the smooth side if the cover it warms the bubbles up on the other side & the bubbles on the solar cover holds more heat than the smooth side
All Solar Pool Covers are placed on your swimming pool with the bubble side down, or facing the water. This allows an air pocket to form under the cover to trap heat & provide the maximum insulation value the cover is designed for. -Charlie Goss President DPD Pools / PoolDeals.com
Use a bubble type solar blanket or cover.
Sun Rings are safer, most are capable of generating more heat that a solar cover. The effect is that Solar Sun Rings with 70% to 80% coverage outperform bubble pack covers with 100% coverage. cheers mark tahiliani (jm)
The didstributor says bubble side down ( for instance solarcovers.com). I do mine bubble side up because when I reel it in the bottom part is in contact with the pool edge and the friction may damage the bubbles.
you make sure the bubble side is facing down on the water.smooth facing uo toward the sky.
They are the same thing basically. Pool Cover, Solar Cover, solar Blanket are all used interchangeably. It's basically some material, usually a plastic bubble mesh or vinyl covering that goes over the pool. The exception to this is Winter Cover which generally is heavier and designed to protect your pool during long winter months.
a heliosphere is a bubble around the solar system blown by the the solar wind.
A transparent cover is better for a solar heating panel as it allows more sunlight to pass through and be absorbed by the black base, maximizing heat absorption. A matte black base is preferred as it is better at absorbing and retaining heat compared to a shiny base, which may reflect some of the sunlight away.
My research online suggests that the 'bubble wrap' technology is standard for solar pool covers since the bubbles form the trapped heat layer. Regular pool covers do come in other styles, including mesh, vinyl or plastic as well as manual or motorized.
The smooth side of a solar pool cover should face down toward the water to help trap heat and prevent debris from entering the pool. The bubbles or air pockets on the cover should face up, as they help to capture and retain heat from the sun.
KWT and TAN both cover the solar space.
