combiBOIL - One Boiler, All Options
combiBOIL offers three different options for hot water preparation:
1. With an electric heating cartridge.
2. Using hot air from the heating device.
3. Via integration into the engine cooling circuit / with a water heating device.
This combination provides maximum flexibility and efficiency for various applications, making it unique in this market segment.
Monitoring and control with Autoterm Comfort Boiler Control.
The Autoterm Comfort Boiler Control Control Panel (a further development of the Comfort Control Panel) is specially designed for the interaction of Autoterm heaters and combiBOIL hot water boilers. This enables an extremely convenient and safe operation of the hot water system. All standard options for heater control as with the Autoterm Comfort Control are retained.
Your benefits:
- Display of water temperature in real-time, even on sleepscreen.
- Water temperature pre-settable from 50 – 80 °C.
- Adjustable hysteresis from 5 – 25 °C from the target temperature.
- Overheat protection (configurable): The air heater automatically turns off before water temperature reaches a critical point.
- Usually, no control flap is needed to adjust airflow into the boiler anymore.
- Frost protection: If the water temperature drops to 2 °C, the heater automatically warms the water to +15°C and the ambient air to +7°C. Boiler and water pipes are reliably protected against frost damage.
The Autoterm Comfort Boiler Control is optionally available, exclusively in combination with the combiBOIL hot water boiler.
Note: Autoterm Comfort Control and Autoterm Comfort Boiler Control differ in hardware and software. The standard Comfort Control cannot be updated for boiler functions.
Hot Shower Kit 2.0
After the development of our original Hot Shower Kit in 2017, we now improved the system by collaborating closely with Autoterm.
The heating devices of our long-time partner from Latvia are indispensable in land and sea travel vehicles. With the Hot Shower Kit 2.0, you don't just get a heater and boiler, but a perfectly matched system.
Thanks to the standard G12" screw connections of combiBOIL, issues like an overheating water line between boiler and mixer are now a thing of the past. A heat-resistant steel flex line is already included as standard.
Optionally available, technically matching components for the pressurized water system ensure reliable technology for travel.
Goodbye Control flap
With the ability to control and monitor boiler temperature, regulation via an Y-piece / control flap is finally unnecessary. Before reaching a critical temperature, the heater can be automatically switched from the current heating mode to ventilation to lower the boiler temperature. The resulting rapid cooling allows the heating mode to restart before a noticeable drop in room temperature occurs. Only with extreme heating demands (e.g., double-digit sub-zero temperatures with sub-optimal insulation) a control flap is still potentially needed.
Couple or large family - Get just as much hot water as you need.
combiBOIL is available in three sizes. With capacities of 7, 9, or 12 liters, just the right amount of hot water is heated up without wasting energy. At a temperature of nearly 60°C inside the boiler, 7 liters of water provide pleasantly heated shower water for two people.
Use with other heaters
Using an Autoterm heater is not strictly necessary for the combiBOIL hot water boiler. Hot air for heating the water can also be produced by other heaters. In this case, however, integration of temperature measurement and safety functions will not be present, as the use of the Autoterm control panel requires a connection to a corresponding heater. A control flap and its manual operation are then prerequisites for safe operation.
Hot Water Connection Kit
Caution: Both the hot water outlet directly on the boiler and the thermostatic mixer can become very hot (depending on the system configuration and settings). Standard (drinking) water hoses and plastic connectors cannot withstand such temperatures over long periods and can thermally deform, which can lead to leaks.
We therefore recommend the hot water connection kit for integrating the boiler into the water system. It includes, among other things, special silicone drinking water hoses (heat-resistant up to 150°C), matching clamps, and connectors. Learn more and order under item number TEX1178.
Please note: When purchasing a Warmduscher Kit 2.0 (combiBOIL boiler + auxiliary heater + installation material), the material from the hot water connection kit is already included and does not need to be ordered separately.

The Autoterm Comfort Boiler Control (ACBC) control panel only controls operation via the air auxiliary heater.
Electric heating and the cooling circuit are controlled and monitored separately, see the following FAQ.
Depending on the heating method -electric, air heater, water circuit- the boiler temperature is monitored and controlled independently of each other.
This means the Boiler Control heater panel does not control the electric heating element or the cooling circuit. That is what thermostat relays are for -or, with the 110/230V boilers, the integrated control of the electric heating element.
Please follow the instructions of all devices -boiler and relays- for controlling and monitoring your combiBOIL!
For general information in advance, however:
If the combiBOIL is combined with the Autoterm Comfort Boiler Control (ACBC), the ACBC temperature sensor constantly measures the boiler water temperature while the auxiliary heater is running. If the measured boiler temperature rises above 85°C, the ACBC interrupts the heater's combustion and switches to fan mode until the boiler temperature has dropped to 75°C. After that, combustion continues. This function applies exclusively to heating the water with the Autoterm air auxiliary heater.
Electric heatingIf you heat the water electrically, the 12V and 24V versions of the boiler come with an external thermostat relay (TSR) in the scope of delivery (boilers from 11/23), which measures and controls the boiler temperature for electric operation, independently of the ACBC. The switch-on and switch-off temperature must be set in the TSR relay beforehand (see its instructions!). If the water temperature rises above 65°C (recommended setting), the relay switches the heating element off. If it falls to 60°C (recommended setting), the relay switches the heating element back on. The thermostat relay's instructions must be followed, and a switch must be installed upstream.
For the 110V and 230V (9L and 12L only) versions of the combiBOIL, the temperature control is integrated in the boiler. The heating element switches off at a fixed 65°C and back on at 56°C. We recommend connecting the heating element to the 230V mains via an illuminated switch for better control.
Cooling circuitIf you connect the boiler to the vehicle's cooling circuit ( Coolant circuit kit ), you also need to integrate a temperature control. For this you use another TSR temperature sensitive relay, which also measures the water temperature in the boiler and, by means of a switchable bypass, routes the coolant through the boiler or past it depending on temperature.
Here, too, follow the instructions of the temperature sensitive relay! At a temperature of 75°C (recommended setting) the relay should switch the bypass and pump the coolant past the boiler. At 70°C (recommended setting) the relay switches back and the coolant flows through the boiler again.
Heating via air auxiliary heater: approx. 1 hour, regardless of boiler and heater size).
When operating via the coolant of the engine cooling circuit, a heating time of approx. 20 min is realistic if the engine is running at operating temperature.
With electricity, the time depends on the power of the heating element. For example, heating a 7-liter boiler with 300W from 15°C to 65°C takes approx. 84 minutes. You can easily calculate the heating time yourself.
Calculate:
(target temperature in °C – starting temperature in °C) x boiler volume in L x 1.2 / boiler heating power in watts x 60 = heating time in minutes.
If you want to learn more about the heating times required, take a look at our comprehensive magazine article on this topic.
You should choose a heating element with on-board voltage (12 or 24V),
If an inverter is present, you can feed more electrical power into the boiler via a 230V heating element, which heats the water faster as a result.
Caution: The towel dryer must not have more output than the heater / heating element feeds into the boiler.
Note that the system should be installed as straight as possible to work efficiently. The smallest Hot Shower Kit (2kW heater + 7l boiler) needs at least 108cm of space before you can continue with individual air ducting/distribution.
For all other setups, heater and boiler sizes, you can roughly add up the lengths of the following components:
Everything that is needed equally for every installation -in a vehicle or boat- and is not individual, we have put into the Hot Shower Kit, so that it is in principle ready and functional.
Depending on your starting situation, you might still need the following:
Of course, our range also includes all other components for building the complete pressure water system, such as certified drinking water hoses, pumps and accumulator tanks, installation material such as clamp jaw clips etc.
In our online magazine there is a detailed article on what is included in which kit and what you might still need.
combiBOIL has a check valve that prevents pressure that builds up from expanding "back". To protect hoses and faucets or shower heads from damage caused by excessive (heat) pressure, an accumulator tank should therefore be used.
With long pipe runs, the accumulator tank is not strictly necessary if the pressure can distribute itself in the piping system.
In a vehicle, long standing times, changing water sources, warming and biofilm formation act together. Controlled water care improves hygiene and protects the entire system. The service life of drinking water point-of-use filters is extended by inhibiting bioactivity.
Chlorine-based products (e.g. Micropur Forte) may only be used strictly according to the manufacturer's dosage, in the cold water system and with limited contact time. Afterwards the system must be flushed thoroughly.
Not permitted:
These applications can cause irreversible damage.
Typical damage patterns are:
This damage is not caused by a lack of material, but by chemical misapplication.
Different disinfectants should not be used in parallel or alternately without flushing in between. This increases the chemical load and brings no hygienic benefit.
Recommended are high-quality plastics (e.g. PEX, PA, PPSU), gunmetal fittings and stainless steel fittings.
Brass is only suitable as dezincification-resistant DZR brass.
Not recommended are copper, galvanized steel and aluminum in water-carrying areas.
Overaged or wrong coolant primarily damages aluminum components and can impair heat transfer. The stainless steel heat exchanger is usually not the first component affected.
These notes apply to all our 316L stainless steel boilers, regardless of size or version.
Our boilers are made of high-quality 316L stainless steel (1.4404) and are designed for drinking water and hot water applications in vehicles. They are robot-welded and pickled and passivated inside and out to achieve a very high level of corrosion protection.
However, the service life of a stainless steel boiler depends not only on the material and manufacturing, but significantly on the way it is operated and on water care.
PERMITTED USE
Use of drinking-water-suitable disinfectants according to the manufacturer's instructions
IMPROPER USE
LIABILITY NOTICE
Damage caused by chemical misapplication, unsuitable disinfectants, overdosing, incorrect material pairings or deviation from this usage specification does not constitute proper use and can considerably shorten the service life of the boiler.
SUMMARY
Our boilers are designed for drinking water.The use of unsuitable chemicals or incorrect disinfection methods can lead to material damage and does not count as proper use.
