Dometic XT 10-Gallon Premium Gas+Electric RV Water Heater
Dometic XT 10-Gallon Premium Gas+Electric RV Water Heater Review
The Dometic XT 10-Gallon Premium Gas+Electric RV Water Heater is Dometic's flagship 10-gallon RV water heater. The "XT" designation reflects premium positioning above the standard Dometic GC10-3E line — adds enhanced controls and improved combustion management.
Specs: 10 gallons stored, 12,000 BTU propane burner, 1500W electric element, recovery ~17 gph propane or 6 gph electric (both modes simultaneously for fastest recovery). Aluminum tank with electronic ignition control. Premium model includes diagnostic LED indicators and improved cold-weather operation.
The XT positioning targets larger Class A motorhomes and high-end fifth wheels where the enhanced features matter. Replaces existing 10-gallon Dometic/Atwood storage tanks with minor trim adjustments.
About $750 unit, $300-$500 install. Parts widely available through Camping World and RV specialty suppliers.
- No combustion, no venting required — installs anywhere with 240V electrical access
- 2-year warranty — well below the 8–12 year category average; extended warranty advisable
- Resistance electric has slower recovery than gas at comparable capacity — schedule heavy use to match tank recovery
- Small 10-gallon reserve — supplemental or 1–2 person use only
- Low 12000 BTU input — slower recovery than modern 40K+ BTU alternatives
