do solar geysers work? If you have been asking
yourself such a question, here is an explanation
that can help you understand the whole concept
of how solar geysers operate. A solar geyser
is a piece of equipment that works through harnessing
the sun’s heating capacity. It puts
in use the thermal conversion principle, hence
making the boiling of water easier. Solar geysers
comprise of two parts: an insulated water tank,
and the flat plate collector. An evacuated tube
joins the water tank and the flat plate connector.
To exploit the heat absorbing capacity, the
flat plate connectors are made using metal or
wood, and the inner walls are painted black.
A thick lid cover allows heat inside and prevents
The water storage tank is used to store both
cold and hot water. The tank is normally metallic
and insulated. It also has outlet and inlet
valves. The tube that connects the water inlet
and outlet is made of copper. Its outer surface
is painted black. Water heating happens at the
collector. Hot water enters the tank and cold
water leaves it through the connector tube.
The water outlet connects with the water taps
through the water outlet pipes.
water is brought into the tank through a copper
tube from where it enters the collector tube
and goes round it. Since the collector is covered
using a glass plate, maximum light and heat
enters via its surface. The heat is further
absorbed by the tubes’ black surface.
This is how the heating of the water is initiated
inside the tube. If you had been asking yourself
the question, how do solar geysers work? You
already have an idea of how the heating starts.
As the heating continues, the hot water leaves
the collector tube and gets into the storage
tank. Since hot water is lighter than cold water,
it floats on the storage tank’s top
layer. Outlet valves at the storage tank’s
upper part are used to supply hot water into
the pipes. Given that fresh cold water is heavier
than the heated one, it stays at the bottom
of the geyser and is directed into the collector
through the tube. If you have ever wondered
how solar geysers work, this is how the water
circulation is maintained in this system.
do solar geysers work? This second bit explains
the operation principle. Solar geysers work
effectively in humid areas. The efficiency of
the device depends on the heat entering the
system. The relation is directly proportional,
meaning that the greater the heat entering the
area, the more efficient the device is. The
performance of the solar heater is also profoundly
affected by the number of flat plates as well
as evacuated tubes applied in the construction
of the system.
water haters have a longer life span compared
to the conventional water heaters. However,
in cold areas, for the device to perform appropriately,
freeze protection should be used and this comes
at an extra cost.
