Life on earth couldn’t be blessed with anything greater that the heat and light from the sun, which is one of the greatest things any living thing can have. It has been possible to harness the energy of the sun absolutely free and that is the reason why the sun is most important planets in the solar system.
Cost of a solar hot water heater:
The solar heater involves a number of different costs. There are the operational costs, installation costs as well as maintenance costs. These costs are compensated with the cost of energy you save by using a solar heater. Depending upon the type of solar hot water heater one can determine the cost of a solar hot water heater.
There are two types of solar water heating systems. One is the passive solar water heater and the other is the active solar water heater. Installation costs of these two types will determine the cost. A passive solar water heater works on the simple principle that cold water falls and that hot water rises. It has not moving parts and hence this solar hot water heater is compact.The active solar water heater consists of a pump that circulates thus helping in maintaining temperature control. A small pump is required in the active solar water heater as it helps in circulation of water. No tank is essential in the active water heater. No pumps are required in the passive solar water heaters, but the tanks are necessary. It is because of the different accessories present or absent in the two types that the cost of a solar water heater might vary.
Working and design of a solar water heater:
One of the biggest boons to mankind is the availability of solar energy. In these times of inflation and severe economic crisis, the sun has been the constant supplier of solar energy to mankind and will continue to do so for millions of years. Solar energy is free from pollution and hence is one of the most eco friendly options available to mankind. Solar power is being used in a number of popular applications like the solar cooker and solar air conditioner as well as the solar water heaterWith affordable cost of solar water heater it is possible for many people to own one. One of the major aspects of a solar water heater is its cost. The solar water heater is mainly designed to heat water and it is the design which determines the cost of a solar water heater. A fluid system and a number of solar collectors help in transferring solar heat from these collectors to the point where they are required to be used. Many business owners as well as home owners own solar water heaters as they are good for use almost everywhere.
They help to generate electricity, for heating water and can be used for sanitary purposes also. The collector which is made of a glass topped insulated box, is normally fixed onto the roof top, faces the sun and collects a lot of solar heat from the sun. The insulated box has solar absorber made of black painted sheet metal has copper piper attached. Cold water is pumped into the collector then gets heated with the solar heat and can then be used from the collection tank, where the water gets collected.
Added longevity and service:
The cost of a solar water heater comes in different ranges. The operational costs of a solar water heater are not much as compared to the electric water heater and the gas water heater. The life expectancy of the solar water heater is very high which may go up to three decades even. When you compare the cost of a solar water heater, to the operational costs of the solar heater for that many years, you will see that the cost of the solar heater is recovered within just a few years.
The amount you save on electricity can be termed as your savings, by purchasing a solar water heater. Everything cannot be weighed in terms of money and hence by using the solar water heater you will be contributing greatly to the cause of the environment. By harnessing solar energy you will certainly be helping to save costs on fossil fuels and other sources of energy.
