ABSTRACT
This article presents the results of field tests of an innovative capacitive solar water heater for 200 liters. Which has a
number of advantages unlike standard water heaters in low cost, ease of manufacture, ease of operation, reliability,
local materials, long service life, ease of repair, transportability, lighter weight, no heavy tubular structures, the
capacitive innovative solar water heater design developed by us is necessary in rural areas for dekhkans and farmers.
KEYWORDS
Capacitive solar water heater, solar energy, container, polyethylene film, absorber, matte paint, support table, thermal
insulation, individual households, tubular collectors.
INTRODUCTION
In the nineteenth century, there were no simple and
comfortable methods of heating water; wood-burning
stoves were used. In cities, lighting gas was used to
heat water. Swiss scientist, botanist Horace de Sausure

in 1767 created the world's first solar water heater for
25 gallons of water. The solar water heater consisted
of a wooden box covered with glass on top, the box
was thermally insulated and blackened from the inside,
and placed a flask with water inside [1-4].
THE MAIN PART
First commercial solar water heater. patented by K.
Kemp and went on sale in 1891 under the name
"Chimax Solar Water Heater". In 1904, Charles Haskell
bought the rights from Kemp to improve the design.
Then in 1909, William J. Bailey revolutionized the
market. He created a new design, divided a single solar
water heater into two parts. The heating element-solar
collector is located outside under the influence of
sunlight, and the storage tank is located inside the
building. By the end of World War I, J. Bieli had sold
4,000 solar water heaters on the market. The modern
type of solar water heater was created in 1953 in Israel
by engineer Levi Issar and improved by Dr. Zvi Tavor in
1955, for which he received an award of 1000 Israeli lira
from the country's Prime Minister David Ben-Gurion.
Currently, solar water heaters of various modifications
[5-9] are widely used in Israel, China, Spain, Saudi
Arabia, Korea, Russia, Portugal, Egypt, Dubai, France,
Morocco, Egypt, Turkey, Italy, Greece, USA and other
countries about the production of solar water heaters
China is the world leader. Solar water heaters can be
active or passive types. The active system uses an
electric pump to circulate the fluid. The passive system
does not have a pump, the process proceeds due to
natural circulation. The solar water heater developed
by us is recommended for use in household plots, rural
areas, individual and farm households, hospitals,
laundries, college dormitories, schools, colleges, and
auto maintenance. The ease of operation of the
developed solar capacitive water heater is its
extraordinary simplicity and reliability, long service life,
the possibility of acquiring a storage tank in any market
of regions. The absence of bulky tubular solar
collectors, which quickly scale up on the inside in hard
water, with their large areas and heavy weight, gives
our solar water heater great advantages. Handles are
installed on the side for the convenience of carrying an
empty barrel, there is a tap for draining hot water. The
cost of industrially produced solar water heaters on the
market is from 4-6 million soums or more, the
proposed solar water heater is an order of magnitude
cheaper than domestic and foreign ones. Does not
demand special service and is easily repaired [10-14].
The tests were carried out in the city of Fergana. They
showed, that the 200 liter solar DHW tank can provide
hot water around 45-55 degrees
℃
for a large family,
especially in remote areas where there is no gas line
and electricity [15-19]. The temperature of hot water
meets the standards for use in domestic and
household needs. The solar water heater consists of a
conventional commercial barrel with a capacity of 200
liters, a lid, a polyethylene bag, a special metal support
table with a built-in absorber, painted in black matte
paint, on which a barrel of water is installed. A special
heat-insulated table with an absorber simultaneously
serves as a support and an additional heating device.
All parts of the water heater are available and are
available in rural stores and are painted with black
matte paint. The heat of the sun's rays heats the unit
from 3 sides, on top is the lid, the div of the barrel
itself and a special heat-insulated support table with an
absorber. The lid of the barrel is painted with black
matt paint and fits snugly to the edges of the barrel,
this ensures that heat enters due to heat conduction
from above. Thus, using BU barrels, it is possible to
produce energy-efficient, cheap and reliable solar
water heaters with a long service life for rural residents
who are in dire need of hot water for washing clothes,
bathing and other household purposes. On the inside,
the barrel has a polyethylene coating (polyethylene

bag) that protects the metal div of the barrel from
corrosion and at the same time serves as a water
reservoir. The water is inside a plastic bag, which allows
you to maintain the high quality of the heated water,
the inner surface of the barrel and its coloring do not
matter. We choose ready-made tanks produced by the
industry for fuels and lubricants, as it is convenient,
cheaper and takes little time than inventing and
manufacturing ourselves [20-17]. Solar water heater
complies with environmental standards does not use
fuel, electricity, natural gas, coal, firewood and other
fuels, so it is recommended for residents of remote
areas without energy sources, as well as cemetery
workers to improve service. The proposed simple solar
water heater can be made from simple locally available
materials and manufactured in large quantities for
customers in any rural area, is unusually easy to repair,
so it is unmatched in low cost, ease of maintenance and
efficiency. The installation has passed many years of
full-scale tests, which showed that it is suitable for a
large Uzbek family living in rural areas. It is known that
about 400 kg of firewood is consumed to heat a barrel
of water with a capacity of 200 liters, this barrel of
water is heated by free solar energy supplied to the
helio-water heater during a sunny day [26-30]. By the
evening, when the family is assembled, 200 liters of hot
water are ready for use. Approximately 400 kg of
firewood is consumed to heat 200 liters of water.
Within one month, there is a saving of fuel equivalent
of 400 kg * 30 days = 12,000 kg of fuel in terms of
soums, which is 12,000,000 soums of conventional fuel,
a decrease in carbon dioxide emissions of CO
2
, and the
absolute environmental friendliness of the process.

Fig.1. General view of the developed innovative capacitive solar water heater
The service life is decades, since it does not have
moving parts during operation, it is possible to replace
a plastic bag, which can be purchased at any hardware
store in the countryside. A general view of the
developed innovative capacitive solar water heater is
shown in Fig.1. For ease of operation on cloudy days,
the solar water heater has a backup heater, an electric
heating element with a power of about 400 watts.

The solar storage water heater was located on a site
surrounded by neighboring houses, and the sun's rays
illuminated the solar plant in the morning from 9
o'clock, in the evening at 17 o'clock the sun was hiding
behind the neighboring houses, and therefore the
solar installation did not receive enough free energy
during daylight hours.
