In Chester County, PA, you may be eligible for a rebate for upgrading to an energy efficient heat pump water heater, depending on your utility provider. PECO is offering rebates of $300 for electric heat pump water heaters through their Smart Home rebate program, and PPL is also offering a $300 rebate through their E-power rebate program. For both programs, eligible electric heat pump water heaters must have EF values of 2.0 or higher.

It appears that you are still eligible for water heater rebates if you install the water heater yourself. You can check the PECO rebate eligibility requirements and call 1-888-573-2672 to verify. For the PPL program, you can also check the eligibility guidelines and call 1-866-660-4551 to verify.
