Glossary of Terms
Facade mounting
With this type of mounting, the solar collectors are mounted at an angle of 45-60 ° on the facade.
flat plate collector
Device similar to radiant floor heating that is laid in the earth in order to use heat energy from the earth.
Flat roof mounting
With this type of mounting, the solar collectors are mounted on a frame. This variant is suitable for bungalows and garage roofs or for set-up in a garden area.
Flue gas
Flue gases rise, among other things, during the combustion of fossil fuels such as oil, natural gas or coal. Their composition depends on the fuel type. They consist largely of steam and carbon dioxide (CO2). Furthermore, depending on the fuel, they contain additional materials.
Flue gas loss
The flue gas loss is the part of the unused heat that escapes into the outdoors with the flue gas.
Flue gas venting
The vent or chamber conducting the flue gases through the flue gas system (e.g. through the chimney, through the outer wall or directly out of the roof).
Flue system
The part of a heating system that conducts the flue gases into the outdoors. Earlier, chimneys handled this; today, flue gas systems are being used instead.
