3.4 Recycling
and
disposal
Both your Valliant ecoCRAFT gas heating boiler and its
packaging consist mainly of recyclable raw materials.
3.4.1 Appliance
Make sure the old appliance and any accessories are
disposed of properly.
3.4.2 Packaging
Please leave the disposal of the transport packaging to
the qualified servicing company which installed the
appliance.
Note!
Please observe the applicable national legal
regulations.
3.5 Energy
saving
tips
Installing a weather compensator
Weather compensators regulate the heating supply
temperature according to the outside temperature. No
more heat is created than is required. The designated
heating feed temperature for the corresponding outside
temperature must be set on the weather compensator.
This setting must not be greater than that required by
the design of the heating installation.
The correct setting is normally undertaken by the
heating engineer. Desired heating and set-back phases
(e.g. at night) are automatically turned on and off by
using integrated time programs.
Weather compensators combined with thermostat valves
are the most economical form of heating regulation.
Reducing the heating system
Reducing the room temperature at night and in your
absence. This is best and most reliably realised using
regulators with customisable time programs.
At such times, set the room temperature approx. 5 °C
lower than during full heating times. Reduction of more
than 5 °C brings no additional energy saving, because
then increased heating capacities would be needed for
the next full heating period. Only for longer absences,
e.g. holidays, is it worthwhile to further lower the
temperatures. However, in winter, make sure that there
is adequate frost protection.
Room temperature
Set the room temperature only as high as would be
enough for your comfort level. An extra degree would
mean increased energy consumption of about 6%.
Adjust the room temperature according to the purpose
of use of the room. For example, normally, it is not
required that bedrooms or seldom used rooms are
heated to 20 °C.
Setting the operating mode
In warmer seasons, when the apartment needs no
heating, turn the heating to summer mode. The heating
mode is then shut off, however, the device or the plant
remains ready for operation for water heating.
Uniform heating
Often, in an apartment with central heating, only one
room is heated. Through the encapsulation surfaces of
this room, i.e. walls, doors, windows, roofs, floors, the
unheated adjoining rooms are also heated in an
unregulated manner, i.e. unwanted heat energy is lost.
The capacity of the radiator in this one heated room is
obviously not enough for such an operating mode.
Consequently, the room can not be heated satisfactorily
and an uncomfortable feeling of coolness prevails (the
same effect is produced when doors between heated or
unheated or slightly heated rooms remain open).
This is incorrect saving: The heating is in operation and
still the room temperature is not comfortably warm.
Increased levels of heating comfort and more effective
operation are achieved if all rooms in an appartment are
heated evenly and in accordance with their utilisation.
The building structure can, by the way, also suffer if
sections of the building are unheated or only partially
heated.
Thermostat valves and room thermostat
It should be a matter of course, today, that all radiators
be fitted with thermostatic valves. They exactly maintain
the set room temperature. You can adjust the room
temperature to suit your individual requirements and
ensure effective operation of your heating installation
using the thermostatic valves in combination with a
room temperature regulator (weather compensator).
In the room where the room temperature regulator is
located, all the radiator valves should be fully opened
since otherwise the two regulating systems will work
against each other and the regulation quality can be
affected.
The following actions by the user are seen quite often:
As soon as the temperature in the room gets too hot the
thermostatic valves are turned down (or the room
thermostat is set to a reduced temperature). If it gets
too cold again after a time, the thermostatic valve is
opened up again.
This is not necessary since the temperature regulation
system takes over this task via the thermostatic valve: If
the room temperature rises above the value set on the
sensor head, the thermostat valve shuts off
automatically, when the temperature drops below the
defined value, it opens again.
