Why solar water heating can help our environment- By: Andy Groves
The population of the earth is slowly realizing that natural resources are not endless. Using natural resources in excess is causing the earth to deteriorate and will eventually become uninhabitable. Scientists are constantly working to find other ways to provide basic necessities like heat and power to every home in the world. One of those things includes solar water heating devices.
Typical water heaters are energy vacuums. They constantly cycle on to keep the water in the tank warm, no matter if it is being used or not. Water heaters are not something that can be turned off and on when they are not in use on a daily basis. For this reason alone, solar water heating can save a homeowner a great deal of money, while limiting a homeís carbon footprint on the world. Solar water heating units have a much longer expected life than typical water heaters, saving our landfills from excess waste.
The initial investment for a solar water heating unit may seem steep, but the amount of money saved in just a few short years makes the cost well worth it. The units rely on the sunís rays to provide power. A solar water heating device provides the hot water needed for any home, just like an electric or gas powered water heater. The sunís rays charge up the device and maintain throughout the night time hours. Cloudy days do not pose a problem, there are still sun rays out there, just not as obvious. However, cold winter days can pose a bit of a problem. Most systems always include a back-up energy source like gas or electricity. If the solar unit does not have enough power to heat the water, the optional power source kicks in.
A professional solar water heating installer can advise a homeowner about the best system for their needs. There are two different types of solar water heating systems currently available. The consultant will also advise a potential buyer about the system that will work best in their climate. A close coupled system involves a water tank being mounted onto a home or buildingís roof. This eliminates the need for a pump. A pump circulated system is similar to typical water heaters currently used. The unit is installed on the ground floor of a home generally, and it uses a pump to cycle the water throughout.
