Heat Your Water Economically With Solar Water Heater

Posted by admin on Jan 13, 2014 in Posts

Hot water is required by everyone, and a water heater is an essential need of a family. A conventional water heater uses a good percentage of electricity to meet the water heating needs, which proves to be really costly in the long run. An approximate amount of 6000 kilowatt hours is consumed only by an electric heater in a year when used by an average family of four. This amount of electricity when multiplied by all the homes using the water heater, will amount to huge amounts of electricity being produced and wasted and production of more carbon dioxide, than automobiles do. Carbon dioxide causes the greenhouse effect and increases the heat inside the atmosphere. All this can be controlled by using a solar water heater as it doesn’t use electricity or any other fuel, only the sun’s energy, which is absolutely free. Solar energy is very friendly to the environment and does not create any type of waste and does not pollute the atmosphere. That is the reason why it is ecologically acceptable, as well.

There are mainly two major types of solar water heater. One is an active solar water heater and the second are passive solar water heaters. The difference lies in the types of heating systems. In case of active solar water heater, water is heated by using direct and indirect circulation systems whereas in passive water heating systems water is heated by integral collector storage and thermo siphon system.

A solar water heater has a high initial cost, the price, which can easily be provided by any nationalized bank, at very low interest rates (3% to 5%), which in turn brings huge savings for your family. A solar water heater typically has a life span of more than 25 years and if properly installed doesn’t require servicing and maintenance.

Different factors determine the amount of hot water provided by solar water heater, the principal one’s are:

•  The amount of sunshine the site can access.

• The type and the size of the solar heater to be installed are considered according to family requirements.

• The weather of the area.

• .Basic design of the building, where it has to be installed.

Electric water heaters consume a large (15 to 20%) proportion of electricity which as the time runs adds up to large amounts. Home owners who have installed a solar water heater unit keep on praising it and are overwhelmed that they did. They save money on a monthly basis and have an abundant amount of hot water for their use.
