The majority of solar
saunas that you will find for purchase seem to be quite expensive, and
most if not all of the websites for these saunas require you to contact
them to inquire about the price. Anyone who is used to shopping for
higher end products knows that it is almost never a good sign when a
company refuses to list their price, as this usually means that the
product is much more than the average person could afford.
Nonetheless, there are
several different types of solar powered saunas that you can check out
to see if they are right for you. The other option is to attempt to
yourself, and we’ll give you a few hints on the different
ways this can be accomplished. First we will take a quick look at some
of the different designs available to give you a little better idea how
to go about trying to construct your own solar powered sauna should you
choose to attempt to do so.
The Sauna Box by Castor
Canadian design company
Castor Designs produces the
Box which is actually an old shipping container that has
turned into a sauna. The only issue with this product is that we are
not convinced that it can truly be called a solar sauna. The sauna
comes equipped with solar panels on the roof, but also a wood burning
stove inside to provide heat.
This means that the sauna
will still produce carbon emissions, and one of the major selling
points of solar energy is that it is emission free.
The solar panels on
this particular sauna are actually there to supply energy for the
stereo and speakers that come along with the sauna. In fact, it evens
come complete with iPod and guitar hook ups for those who like to rock
Solar Exergy Technology,
SETI is another
Canadian own company
that manufactures a line of three different passive solar saunas. Their
designs feature large windows and are specifically designed to collect
and retain the sun’s heat in much the same way as a greenhouse uses its
large windows to heat its interior.
The company states that
each of the three different models can be customized to fit almost any
space requirements and budget, although no prices are listed and you
must contact them about the saunas.
Whether you decide to
of these products is your own choice and very little information is
available on how well they work apart from the company’s own
Nonetheless, the concept
that these products utilize has been used since the time of the Ancient
Greeks and Romans, and it is extremely reliable provided you live in an
area with enough sunlight. The Solar
Exergy Technology, Inc. site is a good place to get ideas for
the design of your own solar powered sauna.
Design and Build Your Own
With a proper amount of
research and a little technical knowledge, it is possible to construct
your own solar energy sauna, although how well it will function depends
on your building methods and quality. There are several different
options for how to heat your sauna using solar energy.
You may wish to use only
one method, or you could combine both methods to get the most out of
your sauna. No matter what how you decide to heat your sauna, the most
important thing is to ensure that your building is extremely well
insulated and air tight to prevent any heat loss.
The first method is by
solar heating, which usually involves the use of windows
to let in light and heat, which is then trapped and stored inside the
building. A great example of this can be seen in the SETI designed
saunas. This is usually the cheapest and easiest way to use solar
energy to heat your sauna, although it may not be the most efficient.
By utilizing the greenhouse effect, it is possible to create
temperatures in excess
of 190 degrees Fahrenheit (90 degrees Celsius)
which is quite impressive.
Solar radiant heating
involves the use of solar water heating panels on the roof of your
sauna which heat water that is then pumped throughout the building.
This same principle is often used to heat homes, and can be quite
efficient, especially in very small spaces.
To make this type of sauna
completely solar powered you will need to also install PV solar panels
to create electricity to power the water pump. In order to install this
type of solar heating, you will need to add a heating element
throughout the room. Usually this consists of a series of pipes or
baseboard heaters that circulate the water around the entire
These work best when they
are placed as close to the floor as possible, without actually touching
the floor. You could also have the heated water hidden behind the walls
and floor and circulated throughout the entire building, although this
will add extra costs and is unnecessary if you have properly insulated
to Solar Energy
