South Carolina Rebate Program

Natural Gas Water Heater Rebates

Commercial water heaters consume a considerable amount of energy, accounting for about 11 percent of the total energy load, on average, in many commercial facilities.

Upgrading to a higher-efficiency water heater can result in recognizable energy savings. The Natural Gas Water Heater Rebate Program for businesses will offset some of the incremental cost associated with choosing more efficient equipment.

Commercial customers in South Carolina who replace existing natural gas equipment with new qualifying high-efficiency natural gas equipment are eligible for up to a $250 rebate. This includes the following qualifying high-efficiency gas water heater. 

Rebates currently available:

Note, effective Jan. 15, 2018, the minimum efficiency requirements for water heaters changed. These changes are a result of new water heater standards that the Department of Energy (DOE) implemented in 2017. DOE revised its testing and qualifications for water heaters and the standards changed from using an Energy Factor (EF) to a Uniform Energy Factor (UEF). As a result, the qualifications for the Piedmont Natural Gas Equipment Rebate program changed to reflect cost-effective water heater energy savings utilizing the new Uniform Energy Factor (UEF).  For tankless water heaters, the minimum rebate qualification changed from an EF of 0.82 to a UEF of 0.81. The rebate amounts and revisions are reflected in the table below.
