Solar water heater particularly in an area with plenty of daily direct sunlight such
as Arizona state will provide an amazing return on investment, save energy, save money and reduce ones carbon footprint with environmentally friendly solar energy. A solar water heater can be a power support 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 nearly 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 represents 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 typical 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 importance to everyones home and significantly reduces water heating bills.
