GSW water heater outer jacket is very hot to the touch or insulation seems inadequate

Safety: Turn off power or gas if overheating is suspected. Avoid contact with hot surfaces.

• Check temperature setting: Reduce thermostat setting to recommended range.
• Inspect access panels: Ensure all insulation pieces are in place behind the upper and lower covers.
• Look for leaks: Remove panels and check for moisture that could compress insulation. Address any leaks found.
• Consider replacement or insulating blanket: For older GSW models with minimal insulation, consider replacing with a newer high-efficiency model or adding an approved insulating jacket (not covering controls or T&P valve).
