Solar water heating is a simple, efficient, affordable technology that provides hot water and saves on energy bills. Columbia Water & Light offers an $800 rebate for a natural gas water heating customer to convert to a solar electric water heating system. All electric customers can receive a $400 rebate for the installation of a solar water heating system. Low-interest loans are available to Columbia Water & Light electric customers for the installation of a new solar water heater system.

How much will I save?
By using a solar water heating system, residents can typically cut their water heating costs by 50-80%. The average Missouri family of four, spending approximately $455 annually on water heating, would save between $227 and $364 each year. Systems will last 25+ years when installed and maintained regularly (every 4-5 years)
How much will it cost to install?
Up front costs vary widely and depend on the type of system installed. Typical costs range from $3,000 to $5,000 for a standard home installation. Exact price quotes can only be obtained from the installer.
Choosing the System
A family of four needs two 4’ x 8’ collector panels connected to an 80-gallon storage tank. Residents in Missouri will want freeze protection. Both drain-back and non-toxic antifreeze systems offer freeze protection. A back-up heater is needed for cloudy days. Final system choice depends on the specific application and homeowner needs.
