I am trying to determine if we need to include the conventional commercial gas/electric water heater in our Energy Star documentation. This particular type of system is not listed in the ES products list. It seems they are only concerned with gas condensing or heat pump water heaters. I think also since water heaters are covered in ASHRAE 90.1-2007 Section 7.5, as required by EA Prerequisite 2, they would not need to also comply with ES. Does anyone know if we are able to mark our conventional water heater as ineligible for ES compliance?
