Heating your water with the pollution-free Solar Energy can well reduce your carbon footprint and protect the environment
The abundant solar thermal energy is a very good option to replace coal, propane, natural gas, and fossil fuel resources on the earth, making our future sustainable and brighter.
The Solar heating systems can largely reduce your monthly heating bill as they use the free fuel-sunshine to provide hot water to your homes and businesses.
Solar water heating systems use solar collectors to capture sun's energy;
A non-freezing, heat-transfer fluid(or water) in the collectors is heated;
The fluid is then circulated from the collectors and transferred the heat to the water in storage tank;
The hot water run out of the water tank and flow into the house and business building;
The solar fluid is then back to the collector and reheated.
Active solar water heating systems:
The active solar water heating systems have circulating pumps and controls, and usually the water storage tank can be installed in garage or on the ground.
2.Passive solar water heating systems:
The passive solar water heating systems have two basic types:
The integral collector-storage passive systems and thermosyphon systems:
For integral collector-storage passive systems, these work best in areas where temperatures rarely fall below freezing.
For thermosyphon systems, the collectors and water storage tank must be installed both on the roof. These systems are reliable,but contractors must pay careful attention to the roof design because of the heavy storage tank.
A solar water heating system can offset up to 75% of water heating energy costs. A solar water heater can cut a business' water heating costs by 50 to 85 percent, while demonstrating your commitment to a cleaner environment.
