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 E and C (auxiliary heater)
is used to:
• heat the vehicle cabin,
• defrost the vehicle windscreens,
• preheat water-cooled vehicle engines.
The 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 and the
combustion chamber. The Thermo Top E and C heater
has an additional circulation pump.
