As a CPI member you can receive a $25 rebate when you purchase a new energy efficient water heater or up to $50 when you purchase a Marathon electric water heater from CPI. How can you tell if your water heater is energy efficient? Check for the Energy Factor. The closer to 1, the more efficient your water heater is. This rebate applies to new construction as well as replacement water heaters.
