Solar Powered Water Heater

Solar powered water heater uses – surprise, surprise, – solar energy to heat up the water. It’s probably the most environmentally friendly and energy efficient type of water heater. This unit relies on roof-mounted solar panels for energy, which is transferred into the tank to heat up the water. Obviously, this option works best for people, who already had their solar panels installed.

The life expectancy for the solar powered water heater is much longer than that of its rivals – up to 20 years and sometimes even more. However, it is essential not to forget about maintenance of the tank. Also, if you choose a solar powered water heater, it is important to have a backup source of energy — for those dull rainy days.

Seems like it is the most energy efficient and environmentally friendly type of water heater
