VVX Heat exchanger.
The heating system comprises two separate circulation
systems with separate fluid systems.
• Motor circuit
• Living area’s heating circuit
Certain KABE Travel Masters have a heat exchanger
(VVX). The heat exchanger transfers heat from one
circulation system to the other. During travel, the living
area can be heated by the vehicle’s engine.
When the temperature in the motorhome is below the
value set via the control panel, the circulation pump (MKV)
starts. Heat circulates in the convectors.

To counteract heat loss and thus maintain a comfortable
temperature in the motorhome even during severe cold,
the vehicle’s walls, floor and roof are insulated.
It is not possible to insulate the motorhome’s front as ef-
fectively as the rest of the body. Windscreen, side win -
dows and engine bay can all lose heat rapidly. This is also
true of safety features in the driver’s environment.
Implementing the following suggestions reduces heat loss
at the motorhome’s front.
• Internally, use blackout curtains at the windscreen/win -
dows at the motorhome’s front.
• Externally, use insulating winter covers on the winds -
creen/windows at the motorhome’s front.
• To insulate walls and floor from the engine bay, fit a
textile cover on the dashboard.
• Fully integrated motorhomes: use the fans in the dash -
board to blow warm air in at the windscreen.
