Solar Heating
Systems can be either passive or active. Passive solar heating
relies on building design to collect and hold sunlight. Passive solar homes
have large, south-facing windows and thermal mass surfaces. Thermal mass is an
absorptive material such as tile, concrete, or even water, which collects and
stores heat for later use. The thermal mass can be incorporated into flooring
or walls. Active solar heating systems consist of solar collectors, heat pumps,
exchangers, storage tanks, and controls to gather, transfer, and disburse heat
throughout a home. Active systems rely on electricity to move the gathered heat
from the solar collector through the home. Both alternative heating methods use
a completely renewable source (the sun) to provide warm air and hot water to
homes. N ...
