Product details

The FLOW 5D compact diesel liquid heater from Autoterm features an impressive heating output of 5 kW and can be used in combination with heat exchangers, boilers and radiators. It can also be used pre-heat the vehicle engine and compartment. The cold start function guarantees engine starting at low temperatures (down to -45°C), which also increases the service life of your engine. Can be operated with the engine switched on or off. Supplied with installation kit and control panel.

Water heater advantages
  • Excellent heat distribution
  • High level of efficiency with correct insulation
  • Pleasant radiating heat (no dry air as is the case with warm air heaters)
  • Automatic heating
  • Cost-effective operation
  • Optional radiators can be individually adjusted

Standby mode
In standby mode, the heater shuts off when a settable temperature threshold is exceeded and the pump continues to operate. The value can be set between 20 and 95° C. If required, the pump run can also be deactivated in standby mode.

Including control panel
Delivery includes virtually everything that is needed for basic installation. The Comfort Control display panel boasts a modern design and numerous functions, such as three adjustable timers, extended heating modes, fan functions and much more. The intelligent thermostat function, for example, automatically switches the heating on when the temperature falls below a set number and similarly turns it off once a set temperature is reached. Multifunctional rotary knob with grippy rubber coating and OLED display. Small installation dimensions, easy to use, stylish design.

Additional switching inputs
The wiring harness features a gate input for connecting your own remote control or other secondary control unit. This requires only two cables to be connected via switch or relay.

E-mark
All Autoterm heaters have an E-mark (e2) and can therefore be installed without registration.

Gladly again
Excellent after-sales management. I had a problem wiring the control unit. The actual cable colors didn't match the installation instructions. I was immediately connected to a very competent employee at SVB. That's the kind of service you want.
