Glossary. Heating technology explained simply.

All about heating. From A to Z.

When it comes to heating, there are a few technical terms that need to be explained. You can find everything you need to know here. In alphabetical order.


Collective term for environmentally damaging pollutants , which through continual advances in burner technology – a field in which Weishaupt is the world's market leader – are being reduced to a minimum. Nitrogen oxide  emissions  in particular (one of the causes of acid rain) have been drastically reduced in recent years.

Energy resources

A distinction is made between finite energy sources, such as oil or gas, which are only available to us in limited quantities and should therefore be used extremely sparingly, and renewable energy  sources, such as solar, wind, or water power. Despite much progress, and taking even a long-term view, these renewable resources will only be able to meet a small proportion of our energy requirements in an economically justifiable way.

Energy source

Fuel oil, bio-oil, natural gas, LPG, and biogas are used as fuels . Their energy content is released during combustion (fuels ).
