Duoetto Gen 3
10 L · 2.65 US Gal — Dual-Voltage Water Heater
A 12V DC / 120V AC storage water heater built for North American caravans, RVs, marine, yachts, and 4WD builds. Selectable temperature on both supplies — shower, wash, and clean with abundant hot water whether or not mains power is available.
Two Ways to Heat
Automatic voltage detection switches between 12V and 120V and back — so the Duoetto pulls from whatever you have: shore power at the campground, or your house battery out in the wild.
Full-power heating on 60Hz mains. Fast recovery for back-to-back showers when you're plugged in.
Heat straight from your house battery, no generator or hookup needed. Truly independent hot water anywhere you park.
Dial In Any Temperature
Digital control of AC/DC on-off and the full temperature range — the same selectable 86–140°F (30–60°C) span on both 12V and 120V.
