Solar Pool
Heating
Solar pool heating is one of the best
things you can do for your swimming pool. It is also easy
to implement, plus it is very inexpensive. Overall, solar
pool heating is one of the best ways to save energy, and
there are many benefits. The most obvious is the money
saved in fuel costs, but there is also the complete lack
of carbon emissions when using solar pool heating.
Using the sun to heat your pool is one of the
best uses of solar energy. The methods range from very
simple, homemade covers, to solar panels with circulating
heat. Both the solar pool covers and the solar panels are
well within the ability range of a determined
do-it-yourselfer.
Solar pool covers
For starters, installing a solar pool cover
will save you a ton of money. Many pools are heated directly
by the sun, and lose a huge amount of BTU's when left
uncovered. Evaporation steals the heat very quickly from an
uncovered pool, therefore, by simply adding a cover, you
will save tremendous amounts of energy.
There are many types of solar pool covers, ranging from
plastic tarps to electrical roll-up systems that are totally
automatic. Even a simple, manually operated cover will have a
dramatic impact on retaining that precious heat in your
pool.
A type of plastic that has been treated to
resist deterioration due to sunlight is available in the
form of something similar to bubble wrap. This is
particularly efficient and inexpensive. One drawback is that
you must manually remove it and replace it. Plus, it does
not last for many years, as a more expensive pool cover
would.
Solar pool heating
For many climates, it is common to install
either a conventional gas heater or use a heat pump to heat
a swimming pool. Solar pool heaters are competitive with
these conventional systems, over time. The solar system is
simple and requires very little maintenance, and should last
for many years.
The solar pool heater functions by using a pump
to move the pool water through a filter and then into the
solar panels to circulate and gather heat. This heated pool
water is then pumped back into the pool, and the process is
repeated continuously, or as needed.
The system may also contain a check valve in
order to bypass the solar panel when necessary. One example
of this is when the temperature in the solar panels is not
sufficiently hot. The pool water is simply circulated
directly back into the pool.
What about the weather?
In very hot climates, it can be advisable to
use the solar panels at night, to cool the pool water. Once
the warm pool water is circulated through the cool solar
panels, the cooled water is returned to the pool. This
represents yet another savings with the solar pool heating
system.
Wherever the climate stays above freezing,
solar panels are made without glass glazing . This reduces
the cost and is often quite efficient for home use.
In those climates that experience freezing
temperatures, glass coverings, or glazing are needed. These
are more expensive than unglazed panels, but are often more
efficient. This efficiency is partially due
to the heat exchangers and heat transfer fluids that are
installed, which absorb more heat from the sun. The glazed
panels can also be used for domestic hot water
systems.
There are many good reasons to use solar pool
heating. Cost savings, reduced fuel consumption, no carbon
emissions, longer life than conventional systems, and the
satisfaction of knowing that you are doing something good
for the earth are just a few of the benefits.
