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 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
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
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
Integrated Thermostat

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

Minimized Heat Loss
