Solar Heating Systems
A solar water heating system can be a great option to save money and help the environment, but deciding to install solar panels is a major investment. In evaluating whether this is the best choice, you should first take account of your home's solar exposure. Does it get enough sun that installing a heater would be economical? You can figure this out by using tools at energysavers.gov or contacting a local solar contractor.
Next you must determine what type of system to choose. If you live in a warmer environment then a direct circulation system is best, whereas those living in colder climates should select an indirect circulation system. Other things to consider are the size of your home, total overall cost, and ease of installation. You should then consult with a solar contractor for parts and installation service.
