Water heats as hot air passes through the boiler.

AUTOTERM combiBOIL 12L
High-performance hot water boiler with three versatile heating options - Air Heaters, Flow Heaters, and Electricity. Designed for durability, its saltwater-resistant 316L stainless steel body ensures reliable, long-lasting performance in any environment.
Available power variations - 12V 300W | 24V 600W | 120V 500W | 230V 500W
MAXIMUM CAPACITY FOR ULTIMATE COMFORT
The 12-liter model delivers the highest hot water capacity between combiBOIL models, making it perfect for larger RVs, boats, and off-grid setups. Despite its increased volume, it remains efficient and seamlessly integrates with any AUTOTERM system or operates independently on electricity, ensuring maximum comfort without compromise.
-
Mixed with cold water, 12-liters is usually enough for three adults to take consecutive showers.



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 Air and Flow Series heaters.
EXTENSIVE COMPABILITY!
These boilers are ideal both for new installations and upgrading existing systems.



With Air Heaters
With Flow Heaters
Water heats as hot coolant circulates through the boiler.
Works Independently
This can boiler operate independently, using electricity.
FULL CONTROL WITH A SINGLE PANEL!
The AUTOTERM combiBOIL is controlled with the Comfort Boiler Control panel - an enhanced version of the Comfort Control panel. It's designed to seamlessly manage both combiBOIL boilers and AUTOTERM heaters.

RECOMMENDATIONS FOR THE SMOOTHEST USER EXPERIENCE

DOMESTIC WATER KIT
A domestic water heating kit to make the combiBOIL installation as easy and efficient as possible.
It includes - Pressure tank (1pce); Inlet filter (1pce); 1/2'' to 10mm connectors (3pcs); Hose T-pieces 10x10x10 (2pcs); Hose connector 10mm (1pce); Spring clamps 15,7-16.5mm (18pcs); Male brass hose adapters 1/2' to 10mm (5pcs).



WATER PUMP
Ensures water circulation. If you already have a pressure water pump in your vehicle, you don’t need to replace it to use with the boiler system.
PRESSURE VALVE
Eliminates risks of an overpressurized domestic water system, that could cause leaks.
THERMOSTATIC MIXING VALVE
Mixes hot and cold water to ensure optimal temperature and extend the warm water volume.
