Because concave mirror is used as a converging mirror. This heater converge sunlight rays at a fixed point.

How to Make
Solar Water
Heater and Its
Working
Introduction to solar
water heater:
A solar water heater is a device that helps in
boiling the water or making it warm. Solar water
heaters make use of the solar energy which is
derived from the sun absolutely free. Also the
solar energy is one which is available in
abundance. The solar water heater can provide
hot water for more than 605 of the household
chores. Solar heaters are very cheap and it can
help you save energy by 20%. Depending on the climate the heater helps in water warming.
There are basically two types of solar water
heaters, i.e. active and passive.
The active system makes use of pumps to
move the water and also require a secondary
source of power. You can place these systems
anywhere you want, also these systems help in
providing warm water when the temperature is
freezing cold. A passive system is one that does
not use pump. It works in a different panel initials
heats the water which rises to the top of the
current at the location of the water tank. Cold
water is relatively pushed down to the solar panel
for heating. This system is cheaper and one thing
that has to be noted while using it is, it should be
always placed above the solar panel.
Heating water with the help of solar water history
is indeed a cost effective and is used not only for
residential purposes, but also industries for
generating electricity.
Working of Solar Water Heater: -
Solar water heater helps in heating water with
the help of solar energy for residential,
commercial, and industrial purposes. Basically a
solar water collector that is placed in a wall
facing the sun helps in heating the cold water
with the help of the rays of the sun. The heater
is available in two types i.e. active and passive.
The collectors consist of a box that is insulated
and has a black painted glass cover, a solar
metal absorber that is flat and is fastened to
wires made of copper. Heat is stored in a
separate water tank with an outlet and inlet which
is attached out to the collector. Passive collectors
make use of electricity to produce hot water where there is
no access to sunlight and the temperature is too
cold. Now ltts talk in brief about both these
systems. Passive system:
There are two kinds of primary systems namely
Batch: it is a tank inside a solar collector without
any tubes. The water heats inside and either the
gravity or the tendency of the hot water to rise,
moves the water upwards and the water reaches
the home pipes.
Thermosiphon: In this the water collector and
solar system both are separate. Cold water
moves through the solar collector tubes and then
natural convection pumps which results in hot
water in the storage tank. That water then
travels to home pipes. Active system:
Direct:This system makes use of pumps. The
water moves from solar collectors to storage
tank with the help of electrical pumps.
Indirect: In this system the solar collectors heat
the heat transfer fluid and not the water. The
fluid then flows through a sealed piping of a heat exchanger which is full of water. The water
absorbs the heat from the fluid and then is
pumped inside the storage tank.
Drainback:This is similar to the indirect method.
The only difference here however is that it uses
distilled water as the heat transfer fluid. It has a
separate tank for the distilled water. Pumping out
the heat transfer liquid into a separate tank
makes it perfect for use during cool climates.
On the whole the working of a solar water
heater is not very complicated. If you find it
costly then you can cut down costs and make
one of your own.
