MO-PERC's water heater rebate propgram is considering changes that will not take place until January 1, 2005.  These changes will not affect any rebate or project currently underway.  The single-stage regulator rebate program did change on July 1 to allow up to 20 regulators per location at $30 each.  This is for the replacement of single-stage regulators only, not for new installations.
