2. General Description
The water heater Thermo Top Z supplementary heater is
intended to compensate for the shortage in heat
generated by engines optimised for low fuel consumption.
The water heater Thermo Top C auxiliary heater is used
to:
• heat the vehicle cabin,
• defrost the vehicle windscreens,
• preheat water-cooled vehicle engines.
The supplementary heater Thermo Top Z may be
converted into an auxiliary heater using a retrofit kit.
The heater designed to the evaporator principle operates
intermittently controlled by the temperature sensor.
In order to minimise the battery's workload the heater
switches from full-load operation to part-load operation
after reaching a water temperature of 72 °C.
In this mode of operation the heater operates with
extremely low noise and particularly low power and fuel
consumption.
The heater consists of the combustion air fan assembly,
the control unit/heat exchanger, the burner insert, the
combustion chamber. The Thermo Top C heater has an
additional circulation pump.
