Solar water heater particularly in an area with plenty of daily direct sunlight such as Arizona state will provide a great return on investment, save energy, save money and reduce ones carbon footprint with green solar energy. A solar water heater can be a power backup for utility system failures and it certainly qualifies for Federal solar tax credit and Arizona state solar system tax credits.
If one has an old water heater that needs to be replaced, it normally costs less to install a new solar water heater as its replacement than to replace it with a new water heater of the same type. Every home has to have hot water and people using solar water heater heat the water practically for free. Solar panels are often created for long life and low maintenance. The polyolefin material is resistant to chemicals in the water and scale build up.
The solar water heater system is a closed circuit which circulates water through a stainless steel heat exchanger and the solar panel on the roof. The hot water from the solar panel heats the heat exchanger and the cool water in the water heater tank is then circulated through the hot heat exchanger and brought up to temperature for use in the home.
A solar water heater can produce more than half of the hot water requirements for a regular residential home. However, in the areas like Arizona State the solar water heater can produce more than 90% of all hot water requirements. Without any doubt a solar system adds value to everyones home and greatly reduces water heating bills.About the Author:
