The Dometic WH-6GA water heater is the gas-only 6-gallon replacement unit for RV owners who want a familiar tank-style water heater without adding electric operation. It uses a 10,000 BTU propane burner, electronic ignition, and a lightweight aluminum tank that does not require an anode rod. Choose this model when you are replacing a standard 6-gallon gas RV water heater and want to reuse or select the correct exterior door separately.

Why Choose the Dometic WH-6GA?
The Dometic WH-6GA water heater is for RV owners, service shops, and mobile technicians replacing a matching Dometic or Atwood-style tank water heater. It solves the common failure point of an aging heater tank, unreliable ignition, or worn burner assembly while keeping the familiar tank-style hot-water setup.
The main trade-off is fitment: this is not a universal tankless conversion and the exterior access door is separate. Confirm the model number, fuel setup, cutout, and door requirements before ordering. Most installs also pair the heater with a compatible exterior door, control switch, and any adapter bracket needed for older openings.
