AUTOTERM duoBOIL
The AUTOTERM duoBOIL utilizes two independent heat sources - hot coolant and electric power - to ensure a reliable supply of domestic hot water, whether you're off-grid or connected to shore power.
Seamlessly compatible with AUTOTERM Flow Series heaters and can also be connected directly to the engine’s coolant loop to harness waste heat for warming water while driving or cruising.
LIQUID HEATERS OR ENGINES
Water is heated with the help of hot coolant running through the boiler.
ELECTRICITY
The water is heated by connecting the boiler to an electrical power source.
DURABLE AND ROBUST BUILD
The boiler features a durable, saltwater-resistant 316L stainless steel body with a shockproof, impact-resistant housing for maximum longevity.


Flexible Mounting
Flexible installation on the floor, wall, or sloped surfaces. Its cylindrical shape allows rotation within the two mounting clamps, ensuring a practical fit in any vehicle.

Frost Protection
When the water temperature drops to 2°C, the heater will automatically heat the water to +15°C and Air to +7°C, protecting the boiler from freezing.

Integrated Safety Valve
If the system pressure is too high, a safety valve opens and prevents damage or leaks to the boiler and water system in the vehicle.

Integrated Thermostat
Built-in in the 120/230V versions and as an external module (TSR, included) in the 12/24V versions.

Minimized Heat Loss
Closed-cell polyurethane foam insulation for minimized heat loss.

Overheat Protection
Turns off the heating when the water temperature reaches 78°C.

DC & AC Applications
The combiBOIL is compatible with 12V or 24V DC systems and can also run on 230V or 120V via an inverter or shore power.

AUTOTERM Integration
Fully compatible with all AUTOTERM Flow Series heaters.
