With emergent awareness about global warming, citizens are turning more towards
eco - friendly and green products. Credit to climatic reforms and conferences,
which have made people conscious of their share of work towards the
environment.
More and more consumers are opting for green and solar energy products as they
have now realized the importance of this transition. Solar energy has become
one of the prime resources of energy due to its abundance and varied
advantages.
Manufacturers are slowly coping up with the colossal demand for solar water
heaters and other solar energy equipment. Nowadays energy efficient Solar Water
Heaters are replacing almost all traditional water heaters owing to their
affordability, cost effective nature and proficiency as an alternative.
Primarily there are two types of residential solar water heaters- active and
passive.
Active Solar Water Heaters constitute of heaters with circulating pumps and
control equipment while in passive solar water heaters, the pumps and
additional equipment is missing. Active solar heaters are further divided into
two types:
Direct circulation system- As the name suggests, in these
systems, the water is directly heated and then circulated in pipes all over the
installation. The primary disadvantage is for the regions where water often
freezes in pipes.
Indirect circulation system- this system was developed to
overcome the aforementioned drawback. The system uses a separate heat exchanger
with a non-freezing liquid circulating. The sun warms the liquid, which
sequentially heats the water for circulation in the house.
Passive water heaters are economic, easy to install and operate but relatively
inefficient than active heaters.
Your local (qualified) plumber can provide you with all the necessary
information and cater to all your plumbing needs ranging from installing solar
water heaters to remodeling homes/bathrooms or green plumbing to various
fitting requirements.
The focal part of a solar water heater is the solar panel or the solar
collector. There are three types of solar collectors:
Flat-plate collector
Integral collector-storage systems
Evacuated-tube solar collectors
Flat-plate collector
This type of collector consists of an insulated and glazed flat top. The
surface is made up of weatherproof boxes and a dark absorber plate, which is
covered by one or more polymer layers for protection purposes. The flat plate
collectors are efficient in warm regions. In addition, they are the most
economic forms of solar water heating equipment and can be easily installed
with the help of plumber from a reliable company.
Integral collector-storage systems
The integral collector-storage systems also known as ICS or batch systems are
equipped with a black tank / insulated tubes surrounded by a glazed box for
maximum rays assimilation. The cold water flows through the preheated panel and
thus provides an instant source of hot water. The only caution is that it can
only be efficiently applied in mild-freeze climates due to solidification of
water in pipes during cold weather.
Evacuated-tube solar collectors
The final type of solar collector is the evacuated-tube solar collector that
consists of parallel transparent / translucent glass tubes. Each tube is
outfitted with a metal absorber tube inside. The metal-tube system is connected
to a fin that amplifies the efficiency to several times. The fin absorbs the
solar energy and restrains heat loss due to radiation. The remarkably efficient
collector owing to its unique design, it is also the most expensive solar
thermal collector.
Opting for renewable sources of energy has become the norm these days and such
initiations can save us from the dilapidation and dependence on non-renewable
sources.
