Fuel-fired heater booster (17,000 BTU)
Details & Technology
The heater booster heater unit is a compact water heater that is connected to the engine
coolant circuit.
The 5 kW [17,000 BTU] heater booster can be switched on whenever the engine is running.
The on/off switch is situated to the right of the light switch. When the heater booster is
switched on, a red indicator light comes on in the switch and a symbol lights up in the
instrument cluster.
While used as a booster, with the engine running, the increase in coolant temperature heats
the driver section via the water circuit of the front-end heater. The air is supplied to the
interior through the existing air outlets in the instrument panel or optionally H00 and H13.
After the heater booster has been switched off, the coolant pump and the burner blower
continue running for approximately 3 minutes, then switch off automatically.
Benefits & Arguments
Engine reaches operating temperature as quickly as possible
Faster heater response
This system is particularly recommended for vehicles with BlueTEC engines which will be
used in very cold climate regions. Since these engines are extremely efficient, their
thermal energy may not always be sufficient, at extremely low ambient temperatures, to
guarantee a comfortable level of warmth in the cab.
Remarks
Recommended for passenger vans in cold climate areas. Recommended for cargo vans
without partition in cold climate areas.
Note:
As of 01/2010 US emission regulations require the heater booster to be only optional
with outside temperatures below < 4∘C (39.2∘F).
