World's Leading Trade Fair for Water, Heat and Air Conditioning

ISH: most important driver of the industry

ISH is the world's leading trade fair and international meeting place for the sustainable use of water and energy in buildings. Like no other trade fair in the world, this leading fair stands for trendsetting topics such as the conservation of resources and the use of renewable energies.

ISH Energy

The efficient use of energy is one of the most important issues of our time. ISH presents the latest technologies and solutions to the challenges posed by climate protection and resource conservation. The ISH Energy division is the leading showcase for efficient heating and air conditioning technology in combination with renewable energies and thus the most important platform for future-oriented building technology.

The Federation of German Heating Industry (BDH) is a member of the ISH sponsorship. Along with energy and industrial associations, the BDH organises the technology and energy forum at the ISH.


As the main source of inspiration for the industry, ISH presents future developments in the heating market. In halls 11 and 12, manufacturers show the status quo of modern heating technology and systems, from efficient heat generation to heat transfer. Pumps and other components of the central heating system - expansion tanks, heating fittings, fittings and stations - are concentrated in hall 9.0 and 9.1 under the topic heat distribution.

The single-room furnace area comprises tiled stoves, fireplaces, fireplace and pellet stoves and is located in hall 9.2.
