Dometic 6-Gal RV Water Heater | WH-6GEA / 94002 | Gas + Electric

Get fast, reliable hot water in your RV with the Dometic WH-6GEA 6-Gallon Gas + Electric RV Water Heater (Part #94002). This compact 6-gallon water heater delivers 10,000 BTU of LP gas heating power with electronic ignition for rapid warm-up, plus electric heating element capability for shore-power flexibility — all in a lightweight aluminum tank that's corrosion-resistant and maintenance-free by design. The right water heater for RVers who want dependable hot water without the headache of anode rod replacement.

Fast Hot Water — 10,000 BTU Electronic Ignition

The WH-6GEA delivers 10,000 BTU of LP gas heating power with electronic ignition:

• Rapid heating — gets hot water flowing fast after startup
• Push-button electronic ignition — no pilot light, no matches
• Reliable starts in all conditions
• 6-gallon capacity — enough for showers, dishes, and household water needs

Dual Heating Options — Gas AND Electric

The "GE" in WH-6GEA stands for Gas + Electric — meaning the unit includes both LP gas heating AND an electric heating element for shore power use. That dual-heat capability is genuinely useful:

• LP gas heating for off-grid camping, dry camping, and boondocking
• Electric heating on shore power — saves your propane for when you actually need it
• Use both simultaneously for faster heating in cold conditions or high-demand situations
• Energy efficiency flexibility — pick the heat source that makes sense for your current situation

Aluminum Tank — No Anode Rod Needed

One of the standout features of the WH-6GEA is its aluminum tank construction. Unlike steel-tanked water heaters that require periodic anode rod replacement to prevent tank corrosion, the aluminum tank is:

• Naturally corrosion-resistant — no sacrificial anode rod required
• Maintenance-free by design — no annual anode swap to remember
• Lightweight compared to steel tank designs — easier installation, less stress on the mounting structure
• Long-lasting with proper care

That's a meaningful real-world advantage. Steel-tanked water heaters require anode rod replacement roughly annually to prevent tank failure — a chore most RVers forget about until the tank starts leaking. The aluminum tank eliminates that maintenance entirely.

Compact Footprint — Smaller Than Older Atwood Designs

The WH-6GEA fits a standard 6-gallon cut-out and is physically smaller than the older generation Atwood water heater. That's useful in two ways:

• Easier installation in tight RV compartments
• Direct replacement for older Atwood 6-gallon units (with the right door conversion kit — see below)

Improved Vent Design

The WH-6GEA features an improved vent design that delivers both better aesthetic appearance and better performance. The vent is responsible for safely exhausting combustion gases during operation — proper vent design means safer operation AND better burner efficiency.

Converting from Atwood? Use a Door Conversion Kit

If you're replacing an older Atwood 6-gallon water heater with this Dometic unit, the existing Atwood door won't fit the Dometic — you need a door conversion kit:

• White Door: Dometic 4471011653 / 94946 White Door Conversion Kit
• Black Door: Dometic 94951 Black Door Conversion Kit

Choose the color that matches your existing exterior finish, and order the door at the same time as the water heater to avoid installation delays.

Easy Installation Design

The WH-6GEA includes mounting flanges for straightforward installation in the standard 6-gallon water heater compartment cutout. Compatible with most existing 6-gallon water heater mounting layouts.

Common Reasons to Upgrade

Reasons RVers choose to upgrade to a new Dometic water heater:

• Existing water heater has failed — tank leak, ignition failure, or other end-of-life issues
• Frequent anode rod issues on steel-tank units — aluminum eliminates this maintenance
• Older Atwood unit aging out — Dometic is the current production replacement
• Want gas + electric dual capability
• Want electronic ignition rather than older pilot-light designs

⚠️ Professional Installation Recommended

Water heater installation involves propane connections, water line connections, electrical wiring, and exhaust vent verification. Improperly installed gas appliances are a fire, explosion, and carbon monoxide safety risk. Installation should be performed by a qualified RV service technician. Always pressure-test propane connections and verify proper venting after installation.
