Solar Heating Best For The Environment
Solar refers to the sun and solar heating, therefore, means utilizing the sunís thermal energy to provide space heating and
hot water to homes and buildings. With a natural source of energy, this type of heating system has major benefits to homes as
it can really save a lot of energy, utility costs and produce clean energy. But for the curious mind, solar heating actually
relies on various factors like solar radiation, surface area, surface reflectance, emissivity, ambient temperature and
thermal convection from the wind.
Types and uses
A solar heating system has a solar collector that faces the sun to absorb heat energy. Solar heating consists of active and
passive solar heating. In active heating, pumps are used to move air or liquid from the solar collector to the building or
home. Passive heating, on the other hand, does not need electrical or mechanical equipment but rather depends on the homeís
structure and design for collection, storage and distribution heat. In this type of system, water moves via natural
convection. In most cases, solar water-heating systems work best with conventional gas or electric-water heating systems.
Apart from space heating, solar heat can also be used in heating water and pools. Solar space heaters and water heaters are
made of solar collectors where heat is stored. The system collects the sunís energy to heat air or fluid which, in turn,
transfers solar heat directly to a home, pool or water.
The benefits people get from using solar energy are very valuable. First of all, it is helpful to the environment in that it
does not cause pollution or emit greenhouse gases. It also does not lower the Earthís energy resources. Being
environment-friendly, solar energy is clean and safe for everybody. People need not worry about tanks that contain flammable
materials and about chemical odors.
Solar energy is very reliable because it is not influenced by political and economic factors so people are always assured of
a steady supply. Best of all, itís free because after installing the system, the heat we get wonít cost anything. Only a
small amount of electricity is needed to run the pumps that circulate heated water throughout the solar heating system.
The only downside for this system may be its initial high cost. It might cost more to purchase the equipment and install a
solar system but eventually, users will recover their initial costs by way of great fuel savings and a durable product which
can last form 15 to 30 years.
In the U.S., the efficiency and reliability of solar heating systems have greatly improved the reason they have become
popular options for the home and office. The U.S. Department of Energy and its partners are said to be working hard to design
more solar heating systems that are cost-effective. Their aim is to enable this type of system to reach the average consumers
and help them lower their utility bills. The ultimate goal is to reduce the countryís use of fossil fuels in a bid to
preserve the environment.
