Flow 14D coolant heater
In extremely cold environments, the Flow 14D can also be used as an auxiliary heater by bringing the engine up to its optimal operating temperature during driving when required.
The Flow 14D is supplied as a complete installation kit and is designed for small heating systems with a maximum coolant volume of 70 litres.
Key benefits
- High heating output for compact systems
- Auxiliary heating for engine and interior
- Complete kit for immediate installation
- Available for 12 V and 24 V on-board electrical systems
Installation without inspection approval
All Autoterm heaters are E-marked (e2) and can therefore be installed without registration.
Control units and operation
A control panel is included in the scope of delivery (please select your preferred option). You can choose between the following variants:
Comfort Control
Control panel with multifunction rotary knob and display: easy operation, timer function, voltage display and thermostat mode. A proven all-round solution, also featuring a maintenance reminder and voltage monitoring that can actively shut down the heater to protect the battery.
Touch Control
Modern touch control panel with clear menu navigation. Ideal if you prefer particularly convenient and intuitive operation and want to keep all key information in view.
Tip: optionally available Push Control
Since 2025, two control panels can be operated simultaneously on one heater – for example one in the living area and one in the cab or sleeping area.
The Push Control is a compact, robust button control for quick everyday operation (on/off and power levels). It can be combined with Comfort Control or used on its own for minimal control requirements.
