Dometic 6 Gallon RV Water Heaters

What models are in the Dometic 6 gallon RV water heater collection?

This collection covers the Dometic WH-6GEA series, a 6 gallon LP gas and electric water heater built for standard RV side-wall installations. Confirm your existing cutout dimensions and fuel type (gas only, electric only, or gas/electric combo) before ordering to ensure a direct swap with no cabinet modification.

Will a Dometic WH-6GEA replace my Atwood or Suburban 6 gallon water heater?

The WH-6GEA uses a 12.5" x 12.5" cutout, which matches the standard Atwood/Dometic 6 gallon footprint but does not directly match Suburban's 6 gallon opening (Suburban uses a 12-7/8" x 16-3/8" cutout). If you have a Suburban tank, you'll need an adapter or a like-for-like Suburban replacement. Measure your existing door opening before ordering.

Do I need a 10 gallon water heater instead of a 6 gallon?

A 6 gallon tank recovers fast enough for one or two people taking short RV showers and handles typical galley use. Larger rigs with multiple users or longer showers usually benefit from more capacity, see our 10 gallon RV water heater collection for higher-volume options. Recovery rate and BTU input matter as much as tank size, so check both specs.

What other parts should I pick up with a new water heater install?

Plan for fresh water line connections, a new T&P relief valve if yours is corroded, and winterization supplies for seasonal storage. Our RV winterizing kits cover the bypass valves and antifreeze you'll need to protect the new tank in freezing temps. If you need help confirming fitment, text or call 817-984-1852.
