The purpose of the program is to promote the use of Residential High Efficiency Propane Water Heaters. The program is funded through a refund of assessments paid by propane marketers to the Iowa Propane Education and Research Council. Once the pool of rebate dollars, have been exhausted, no additional rebates will be processed. This is not a government program and it may be terminated or revised by the Iowa Propane Gas Association (IPGA) at any time. The program may be put on hold or discontinued when funds are not available. A completed current application, invoice showing the purchase and installation of the water heater and a safety inspection document must be provided. Please read the rules for all requirements.
