Water evaporation can
account for up to seventy percent of your pool’s heat loss, and a solar
swimming pool cover limits evaporation by trapping and heating a layer
of air between the cover and the surface of the water. The majority of
solar pool covers are thick pieces of material with tiny air pockets
that are heated by sunlight and this heat is then transferred directly
to your pool water.
These products can be
extremely efficient at
heating up the water in your pool, at least at the surface. They can
even be used in conjunction with a pump to entirely heat your pool in
hotter climates. When determining which solar swimming pool cover to
purchase, you need to take a few things into account. Firstly, you need
to make sure that the cover will actually fit your pool!
attention to the covers you find online: most of them should list the
size and shape of pool that they are suited for, and some covers may
need to be trimmed to fit oval or kidney shaped pools.
Another thing to
take notice of is the thickness of the solar cover itself, which is
almost always measured in millimeters. A thicker pool cover will
usually be better at trapping heating and transferring it to your pool,
but a thicker cover also means more weight.
If you have a very
large pool, then a thick cover may be almost impossible to move around
Although many people have
reported that they were able to
simply cut the cover into smaller strips, making it easier to put the
cover on and take it back off themselves.
Thicker covers also cost
more money, so
if you live in a warmer climate, then it may not be necessary to
purchase a 16 mm cover unless you are planning on heating your pool
entirely with the solar cover.
There are many different
brands of solar
swimming pool covers available for purchase in local retail stores as
well as most online retailers. Below we will have a look at two of the
top brands and provide more information on each one. These products
will give you a good reference point for the price and quality you
should expect from a decent solar pool cover.
Swim Time 12 Mil Solar Blanket For In-Ground Pools
The Swim Time solar pool blanket is a great addition to your in-ground pool, and extends the
time of year in which you can use your pool. The blanket is durable,
12-mil thick, and loaded with thermal bubbles that retain heat even at
night and on cloudy days. The bubbles work in a similar way to a
magnifying glass, focusing the sun’s heat into the pool water.
By covering the pool, the
cover also prevents evaporation, saving you money on refilling and
further protecting the water’s temperature.
As well as warming your
pool, the cover has other practical applications.
By keeping dirt,
debris and leaf litter out of the water, you can extend the life of
your pool’s pump, and keep the water more clean and sanitary. You can
even save money on the cost of the chemicals needed to clean and treat
The transparent blue color
ensures that the sun’s warmth can reach through to your pool. In fact,
the solar blanket is capable of making your pool up to 15°F warmer than
an uncovered one. The blanket is also UV-protected itself, so it won’t
degrade, even under the harshest of sunlight.
The blanket is suitable
for in-ground pools and is available in a range of sizes, from 12 x 20
feet, right through to 30 x 50 feet. The covers can be cut down to size
to fit smaller or irregularly shaped pools.
The covers do weigh more
when wet than dry, but they should still be able to be moved and lifted
by a single person. If the cover is particularly large, you may want to
consider using two people or having a simple mechanism in place such as
a solar pool cover reel, or cutting the cover into two smaller covers.
The solar blanket includes
a 5 year warranty, and retails from around $50-$300, depending on the
size you need.
12 Mil Solar Pool Covers
another very popular line of solar swimming pool covers
that are slightly cheaper than the In The Swim products due to the fact
that they are only 12 millimeters thick instead of 16mm. These covers
are recommended for warmer climates, or for people who use a
traditional pool heater and simply wish to reduce heat loss.
Mil Pool Solar Cover is highly
recommended and you should be able to
purchase one at
many different online retailers for between $50 and $100, while the
largest 20 X 40 cover costs around $130.
Midwest also produces a
of smaller solar spa
covers that can also be used for smaller round
pools such as aboveground pools, and they usually cost somewhere
between $20 and $40.
