3. Product information
3.1 Functional principle
The combustion of gas powers a high-performance
alternator that produces electricity.
The heat that is generated by this process is used for hot
water provision and heating.
This principle is referred to as combined-heat-and-power.
3.3 Modes of operation
The system can be operated in five modes of operation
(including shutdown). The modes of operation are set via
the operational display.
“ELCO/Control” operation manual.
3.3.1 Ready for e-car charging button
Special mode for charging electric
to produce electricity in this mode if the storage battery is
fully charged.
3.3.2 Summer operation
In summer operation mode, the system only operates at
minimum capacity. The system only starts if the storage
battery has insufficient charge.
3.3.3 Heat-optimised
The system starts if a temperature requirement has been
set. If the storage battery has reached a specific percentage
charge, the system begins to power down steplessly.
vehicles. It is still possible
The control mechanism manages and monitors the
combustion process in the generation unit. The system is
operated via the operational display on the control cabinet.
3.2 Registering with the energy provider
The energy provider must be informed about the installation
of the system. Obligations of the operator:
A Inform the energy provider about the system before it is
assembled.
A Fulfil the requirements specified by the energy provider
(e.g. registration, approval, compensation).
A Provide the energy provider with all the relevant system
data.
Technical data.
The electricity produced over and above the operator’s own
requirement can be fed into the energy provider’s local
electricity network in return for compensation. A suitable
application must be submitted to the energy provider for
this purpose.
3.3.4 Electricity-optimised
The system starts to operate according to a temperature
requirement. Once a specific storage battery charge has
been reached, the system aligns itself to the electricity
consumption of the building.
3.3.5 Shutdown
The system is in hibernation mode. The system does not
start according to temperature requirements.

applicable laws and regulations for boiler rooms
(e.g. in Germany, the ordinance for heat-producing
appliances (Feuerstättenverordnung)).
B The substrate on which the generation unit is to be
installed must be flat, even, solid, dry and load-bearing.
B The ambient air temperature must be between
+5°C and +30°C.
B The system must be protected against frost and the
elements.
The following are not permitted:
B Installation on floating screed.
B Operation of tumble dryers in the same room.
B Storage of explosive or highly flammable materials
(e.g. paper, paints, petrol) within the installation
location.
B Use of aggressive substances (e.g. sprays, solvents,
chlorinated cleaning agents, paints, adhesives) in the
vicinity of the system.
If the system is installed in vaulted cellars or bare smoothwalled rooms (hard-walled), there is a risk of noise and
sound resonance.

5.2.3 Heating system
The structural elements of the building’s heating system
primarily comprise the peak load boiler, the buffer tank,
and the pipework system and radiators.
The peak load boiler supplies the required residual heat if
the heating energy requirement exceeds the capacity of the
system (e.g. in extremely cold weather).
The buffer tank acts as a hydraulic separator and isolates the
system from the building’s heating system.
For the system to operate, a buffer tank is required, which
must comply with the following requirements:
B The buffer tank must have holding fixtures for the
temperature sensors.
B The buffer tank must have shut-off devices fitted on the
connections to the system.
B The buffer tank must be designed to meet the system
specifications.
B Minimum 100 litres per kW thermal
for installations < 10 kW

12.1 Hydraulic diagrams
The following hydraulic diagrams illustrate examples
for connecting the system to the heating system. These
hydraulic diagrams do not replace the need to correctly
design the technical aspects heating system.
The hydraulic diagram applicable to the heating system
must be checked for correctness and completeness.
The installation location requirements must be observed. In
particular:
B The building’s heating system.
