8 Glossary
Flue gas mass flow Flue gas volume, which the flue gas system dissipates to open air, depending on the preset burner output.
Filling water Water quantity, which is to be filled into the heating system before initial start-up.
Burner setting Adjustments to the gas burner, which should be carried out only by technical staff, for example setting the gas type,
gas air mixture, maximum and minimum output, of the gas pressure controller as well as the electrodes.
Calorific value Energy which is generated during combustion of the fuel as well as of the condensation of the flue gas as heat, and can be
used (synonym = gross calorific value)
Condensing
technology Heat engineering, which uses the condensation heat of the flue gas in addition to the sensitive combustion energy (calorific
value) and raises the efficiency of the system.
EnergySaving
Regulation (EnEV) Legal specification, which defines the standards of the civil engineering and heat engineering and evaluates the efficiency
of the heating and hot water preparation, and which replaced the heat protecting and heating system ordinance on
01-02-2002.
Make-up water Quantity of water to be topped up on water loss.
Automatic firing unit System, which starts and controls the gas burner, monitors the combustion process and switches off the gas burner in the
event of a fault.
Gas/air compound
control System, which adjusts the gas volume flow through the gas pressure controller according to the air-mass flow.
Thermal characteristic Mathematical relationship between outside temperature and target temperature of the inflow (synonym = Heat curve),
required to reach the desired room temperature at every outside temperature.
Heating circuit Circuit of the heated water from the heating boiler to the heating surfaces and back again.
Heating return flow Section of the heat circulation which conducts the cooled water through the pipe system from the heating surfaces in the
room back to the heating boiler.
Heating circulation Section of the heat circuit, which conducts the heated water from the heating boiler to the heating surfaces in the rooms.
Boiler control panel Operating unit in the front area of the heating boiler, which comprises main switch, fault indicators. water pressure gauge
as well as program selection keys, rotary knobs and display.
Condensation heat Energy, which is generated at the time of condensation of the water vapour in the cooling gas and is used in condensing
technology for generating heat.
Air/flue gas system
(LAS) System made of flue gas and air suction tubes, which cools flue gas by counter current and heats the air being drawn in.
On one hand, the generated condensation heat from the flue gas is used. On the other, the flue gas heats the drawn in
combustion air. Both factors raise the efficiency of the system.
Modulation Automatic and continuous adjustment of the heat output to the heat requirement at the time, without having to switch
various heat stages or cycles.
Nominal output Maximum heat output, which the heating boiler emits at certain operating temperatures.
Ambient air-dependent
mode Operating method of the system, in which the heating unit takes the air needed for combustion from the installation room.
Ambient air-
independent mode Operating method of the system, in which the heating unit draws the air needed for combustion not from the installation
room, but through the air-flue gas system from the open air.
Water shortage
protection/
overheating protection Safety device which switches the heating boiler off if there is water shortage, to avoid overheating.
Timer program Times which you can set on the operating unit to define regular heating, economy and hot water phases.
