- Are there different types of solar water heaters?

They all operate on the same principal of water heated in the rooftop solar collector and circulated back to a storage tank, but systems differ by circulation method. To find out more about the different types of systems, visit the following Web sites:
- What is the standard warranty for a solar system and what will it cover?
Specifics on solar systems should be discussed with the solar contractor. Typically, each component has manufacturer warranties. The collector is usually guaranteed for 15 years, the tank for 10 years, and the miscellaneous components for one year or longer. Ask the contractor to provide you with specific detailed warranty information.
- How long will my system last?
Your solar contractor will be able to provide specific details. Typical solar collectors are designed to last for 20 years on average. Storage tanks usually last for 10 to 15 years.
- Do I need to replace my water heater?
Based on your hot water consumption a new, larger storage tank may be required. Your solar contractor will design the appropriate system for your needs.
- Does a solar water heater have any way of storing the heated water, or is it operational only when the sun is out?
All solar systems incorporate a method for storing heated water. Some designs include additional storage in the solar collector. While the sun is only able to heat water when it is out and shining, the water heating system is operational at all times. This is accomplished by the hot water storage and the backup electric heating element.
