SHe-AO Solar Power Heater Flat Plate Solar Thermal Collectors Solar Hot Plate Use Solar Hot Water System
(1) 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.
