Knowing that solar energy is available to us - particularly with the escalating concerns of current supplies of energy and lack of
prolonged availability - is reassuring. Current sources in the
way of fossil fuels are thought to be dwindling and
alternative sources need to be sought. Solar energy is a continual renewable energy source.
It is logical to conclude the sun is not going anywhere nor
will using it as a source of energy provide any worries about future supplies dwindling.
It is also clean and does not provide any less than favorable gaseous
materials to be emitted into the earth's atmosphere.
Knowing all of the above is why consumers who are
concerned about future energy as well as environmental standards
regarding safety and health are easily turning towards solar
energy as a prime alternative energy source.
The following article places emphasis on using a solar water heater in order to save on associated costs of energy and address environmental concerns.

Naturally, solar water heaters make use of solar energy in order to effectively heat water.
The system, in the way of design, is made up of collectors as well as a system (fluid-based) that
transfers the heat from the collectors to the end-consumer.
You can easily use a solar water heater in a residential as well as a commercial location. The water heated can be used in the way
of sanitation or in the generation of electrical service.
In order for the solar heater to operate you must place a
collector on the top of your dwelling or commercial building,
or at minimum upon a wall that is within the direct
path of the sun. The collector is an insulated box with a
top made of glass. Inclusive is a solar absorption area
comprised of sheet metal painted black in order to
better absorb the sun's rays and copper piping.
The absorber can also be made up of metal tubing within a cylinder made
of glass.
Cold water is pumped into the area of the collector where it is heated.
It then flows back to a tank where it is housed for eventual use.
You may be surprised to know solar-style water heaters have been around
for quite awhile. They have been in existence since the nineteenth century.
Also it may further surprise you that currently approximately one and
one-half million commercial enterprises and residents
across America are making use of a solar water heater.
If you believe at this point installation of a solar water heater will prove beneficial within your household or commercial business then you may
wish to search the "net" for construction plans for solar water heaters.
How much do solar water heaters cost? Although fairly free of maintenance, there
is a certain cost to materials and installation before profiting from
overall savings as to energy. This naturally brings up the very important point of cost of the solar appliance.
Do not allow installation of a solar water heater deter you.
Any cost involved can be recouped since maintenance is
nearly non-existent as well as other associative costs
as to energy.
The price you will incur with regard to a solar water heater is relative to the type
or style of water system you select for installation. There
are 2 primary kinds of water-heating systems: a passive system and an active system.
The active system is comprised of a pump and temperature control.
The passive system as the name suggests is absent of
movable parts and works on the proven theory that hot water will come to the
top; and cold water moves toward the bottom. _______ ____________
The active system has a pump but no tank. The passive hot water heater has a tank but no pump.
From the standpoint of efficiency, passive
heaters are not as effective as active heaters.
The passive heater however is very dependable and generally
lasts for a longer span of time than the active heater.
The price of the passive heater is less than the active water
heater. The active (flat) system is priced around the three-thousand dollar price point.
The passive system comes in around half of what the active system costs.
Also besides product price there is the matter
of installation. The cost to install a water heater for use within the household is between three-thousand to five-thousand dollars.
The price stated is for general installation.
However, you may expect the bonus to come in the way of operational expense of the solar water
heater. The cost annually is generally around fifty dollars in order to operate a solar water heater.
Compare that to the average per annum cost of electric
and gas heaters. The current traditional-style heaters come in around an average price projection-point of five hundred dollars.
Your energy-savings realized on a yearly basis can amount to right around $450.00.
(Environmental and Energy Study Institute). Also you can expect your solar heater to provide anywhere from five to fifteen years more service as opposed
to your gas/electric version. The average life for the gas and electric brand is generally around
ten years. In comparison, the solar water heater's useful life is fifteen to thirty years in duration.
The passive style solar water heater does not need near as much maintenance as the active version.
The parts of solar-powered water heaters are maintained very similarly
to how gas and electric heaters are maintained.
Maintenance on the heater is scheduled three to five years.
However, all appliances must be properly maintained in order to work at
maximum levels of efficiency so do not let the associative cost of maintenance scare you off.
In using a solar water heater you are practicing energy conservation as well as affecting a cost saving,
so timely expense as to maintenance need not be an area of
concern. Further, maintenance needs to be carried out regardless of
the type of appliance whether it is electric,
gas or solar and you are paying well more monthly
when using an electric or gas water heater. Solar water heaters are, at
this point, able to provide the average residence with nearly
half of the energy needed to heat the water required.
When you use any type of solar energy you are greatly contributing to a decrease of dwindling
fossil fuel reserves and other more provincial energy
sources.
Another positive consideration is that clearly solar energy generation does not cause pollution. The costs of installation and possible higher maintenance costs are rationalized by the savings incurred when heating the
water. Certainly keeping the environment safe and
healthy cannot be measured price-wise as no amount of money can get back an environment that has
been ruined or destroyed from pollution or neglect. |
