The warm air from the heater can be channeled into the boiler via a 90mm connection and an air-to-water heat exchanger. The inlet and outlet are interchangeable, allowing either side to function as the inlet. The heating duration is influenced by variables such as the initial water temperature in the boiler, the intake air temperature of the heater, and the flow rate. It is crucial to ensure that the temperature within the boiler does not surpass 85°C, necessitating timely shutdown of the heater. The Autoterm Comfort Boiler Control heater control panel facilitates automatic shutdown, eliminating the need for manual control flaps. In instances of exceptionally high demand for warm air, such as very low temperatures with poorly insulated cabins, a control flap may still be beneficial. In the absence of Comfort Boiler Control, warm air should be redirected away from the boiler using a control flap or other suitable methods to prevent overheating.

The boiler can integrate into the motor's coolant circuit to heat domestic water or a second water loop. Conversely, it can preheat the engine for a gentler start, except in extremely cold Arctic temperatures. Integration options include:

1. Heating domestic water while driving, with caution due to potential high temperatures exceeding 100°C, which could lead to boiling and dangerous steam generation. Measures to prevent overheating include using a valve or disabling the circulation pump to limit the boiler temperature to 85°C.
2. Preheating the engine's coolant circuit using a power source or warm air to prevent freezing in low temperatures. The effectiveness depends on ambient temperatures and engine size, and in arctic conditions, combining with an Autoterm Flow heater may be advisable.
3. Transferring heat energy to a second water loop for underfloor heating or a towel drying radiator. Careful regulation of flow temperature and consultation with a dealer is recommended.

The electric heating element can be operated from the 110V shore power.. The heating time depends on the initial water temperature in the boiler. Operate the electric heating element only when hot water is actually needed. Thus, continuous operation to the heating element is not recommended. 

ATTENTION : The electric heating element must not be operated when the boiler is dry. In such a case, no liability can be assumed for damages.

Selecting the correct model can be challenging; here are some tips and information:

DIMENSIONS :

9L CombiBOIL is 484 x 270 x 272 mm / 19.05 x 10.63 x 10.71" for 10.39Kg / 22.91lbs

12L CombiBOIL is : 579 x 270 x 272 mm / 22.80 x 10.63 x 10.71" for 14.53Kg / 32.03lbs

NUMBER OF PERSONS THAT CAN TAKE CONSECUTIVE SHOWERS :

9L CombiBOIL : Up to 3 people

12L CombiBOIL : Up to 4 people

While the use of an Autoterm heater (2D or 4D) is not essential for the operation of the combiBOIL, it's important to note that alternative heaters can also generate hot air for heating the water. However, it's crucial to understand that without the integration of temperature measurement and safety functions, which are only available when used with an Autoterm heater and its corresponding control panel, certain safety features may not be accessible.

ATTENTION : In such cases, the manual operation of a control flap becomes a prerequisite for ensuring safe operation.
