Dometic RV 10-Gallon Water Heater WH-10GEA Gas/Electric — 10,000 BTU Anode-Free Aluminum Tank

The Dometic WH-10GEA is a compact gas/electric 10-gallon water heater engineered for mobile use, delivering quicker heat-up and longer hot-water capacity than standard RV tanks.

The WH-10GEA (95001SP) combines a 10,000 BTU electronic-ignition burner with an aluminum, anode-free tank to supply reliable hot water in RVs, campers and other mobile applications. Its 10-gallon capacity is about two-thirds larger than many common tanks, and the unit includes a factory-installed winterization bypass to simplify cold-weather prep. Note: the front access door is sold separately.

How quickly does the WH-10GEA produce hot water?

This model uses a 10,000 BTU electronic-ignition burner to reach usable temperatures faster than lower-output units. The higher BTU rating shortens recovery time between draws, so you get ready hot water for showers, dishwashing or general crew use.

• 10,000 BTU electronic-ignition burner for faster heat-up
• Dual gas/electric heating options for flexible power sources
• Aluminum tank conducts heat efficiently for quicker recovery

What makes the 10-gallon tank different from standard RV heaters?

The WH-10GEA's 10-gallon capacity is approximately 66% larger than typical stock tanks, letting you run longer showers or back-to-back hot water tasks without immediate recovery waits. The tank’s lightweight aluminum construction removes the need for a sacrificial anode, lowering maintenance points.

• 10-gallon capacity for extended hot-water availability
• Lightweight aluminum tank with no anode required
• Good balance of capacity and compact footprint for most RVs

How does the WH-10GEA handle cold-weather use and maintenance?

This unit arrives with a pre-installed winterization bypass kit to simplify draining and freeze protection procedures, reducing the steps needed when preparing for storage. Routine upkeep is easier because the aluminum tank eliminates anode checks, and the electronic ignition reduces pilot-related maintenance.

• Pre-installed winterization bypass for straightforward cold-season prep
• Electronic ignition minimizes pilot maintenance and gas waste
• Anode-free aluminum tank cuts routine replacement tasks

What installation and compatibility points should I consider?

The WH-10GEA is designed for mobile installations and fits many RV and camper configurations, but confirm cabinet depth and ventilation clearances before purchase. Keep in mind the accessory front access door is not included, and you’ll need to verify fuel source compatibility and local installation codes.

• Front access door sold separately — check model fitment
• Requires adequate ventilation and correct gas/electrical hookups
• Compact footprint tailored to mobile application spaces

Who is this for: The Dometic WH-10GEA is suited to RV owners, caravan renovators and mobile-living enthusiasts who want faster recovery and more usable hot water than standard small tanks offer, without substantial added weight. It’s a practical choice for those who value simplified winterization, low-maintenance tank design, and the flexibility of gas and electric heating options. Confirm dimensions and door accessory needs for a smooth installation.
