A
solar pool
heater is generally the most cost-effective solar technology
option. However, many of those who are interested in purchasing such
a heater hesitate simply because they do not understand how it works.
Though it functions in a relatively simple manner, a solar pool heater
system includes pumps, filters, flow control valves and collectors.
This can appear daunting at first; however, most of this need not affect
the typical homeowner. A solar contractor can be used to set up these
important parts and is in fact recommended.
The flow control valve of a solar pool heater may be automatic or manual.
An automatic version will sense when the solar collector has reached
an adequate temperature. At this point, the pump will begin circulating
the pool water through the system.
In order for a manually-controlled system to work properly, it is the
responsibility of the homeowner to set the timer that comes with the
system. What the timer does is allow the pool water to be filtered at
precisely the same time that the solar collectors gather radiation.
Typically, the best time to do this is mid-morning to late afternoon.
This is when the sun is brightest and hottest. Of course, it can be
done at other times as well. In fact, a solar pool heater is capable
of doubling as a cooler.
This possibility is ideally achieved during the warmest of the summer
months, with pools that are uncovered. The system can be started sometime
between the late evening and very early morning hours when the sun is
hidden. When the collector is cool, it will actually cool down the circulating
water if it is too hot for comfort during the day time.
