In response to a preliminary technical support document (PTSD) for energy conservation standards for consumer water heaters, CFA and other advocates submitted comments urging DOE to evaluate additional technology options for gas storage water heaters including gas-actuated non-powered dampers and gas-fired heat pump water heaters. including gas-actuated non-powered dampers and gas-fired heat pump water heaters (HPWHs). We also encourage DOE to analyze 120V/15A electric storage water heaters. In addition, we encourage DOE to investigate how the analysis could address price learning specifically associated with heat pump and condensing technology. Finally, we urge DOE to evaluate one or more alternate natural gas price scenarios that reflect electrification and other trends that could result in significant increases in natural gas prices.
