Solar water heating is one of the best ways to get started in solar. On average, Americans spend around 25% of their total energy consumption heating water. A solar water heating system eliminates most of that cost and has a back-up heating element so you'll never run out of hot water.
Your water is pumped up to a solar collector designed to get your water extremely hot. That hot water is then pumped down and stored in your new water tank for future use.
