Solar Heaters
Solar
heaters provide heat for space and water with solar energy
in two different ways. Because utilization of this type of home heating
involves mechanical equipment, it is described as "active solar
heating." If the heat was provided through the design and structure
of the house, it would be called "passive solar heating."
The two general groups of solar heaters are those that heat air and
those that heat liquids. All solar heaters use solar energy collectors
to heat whichever base fluid they utilize, be it air or liquid.
Solar heaters which are air-based systems heat air in an "air
collector." They can provide ventilation heating as well as space
heating. Liquid-based solar heaters use a "hydronic collector"
to heat such fluids as water, antifreeze solutions, or another type
of heat-storing liquid. They are ideal for central heating as well as
water heating.
