They also understood the huge rock of the cliff might absorb heat in winter and safeguard from wind and snow. At the same time, the cliff-dwelling style blocked sun light during the summer, once the sun is higher in the sky, keeping their dwellings cool. The modern version of this sun-welcoming design is called passive solar since no pumps, fans, or other mechanical devices are used. Its most basic functions include large, south-facing windows that fill the house with natural sunlight, and dark tile or brick floors that store the sun’s heat and release it back into the house at night.
Throughout the summer, once the sun is higher in the sky, window overhangs block sunlight, which keeps the house cool. Tile and brick floors also stay cool during summer. Passive solar style combined with power efficiency will go further. Energy-efficient features such as energy-saving windows and appliances, together with good insulation and weather-stripping, can make an enormous distinction in energy and cost savings. Solar energy may be utilized to heat water for your house or your swimming pool. Most solar water-heating systems comprise of a solar collector and a water storage tank.
Solar water-heating systems use collectors, usually mounted on a south-facing roof, to heat either water or a heat-transfer fluid, like nontoxic antifreeze. The heated water is then stored in a water tank comparable to 1 utilized in a standard gas or electric water-heating program. The quantity of warm water a solar water heater produces depends on the type and size of the program, the amount of sun available in the site, correct installation, and the tilt angle and orientation of the collectors. But if you’re presently using an electric water heater, solar water heating is really a cost-effective alternative.
