The heating transition begins at ISH.
Visitors to the ISH trade fair can expect to see the most important trends and innovations in the field of heat generation. Whether renewable heating systems, heat storage tanks, local and district heating systems or smart heating solutions, visitors can discover the innovative heat generators that are making heating in residential and commercial properties more efficient and environmentally friendly, both now and in the future. Sustainable heating technology based on traditional, renewable or hybrid sources of energy plays a pivotal role in reducing CO2 emissions and cutting costs in keeping with the goals of the Paris Agreement.
In our video, Vanessa Perner explains everything about the ‘Heat Generation’ solution area - and shows how innovative solutions can be used for efficient heating in residential and commercial buildings.
The application areas in the heat generation solution field at a glance
Electricity-based heating systems
According to the International Energy Agency (IEA), 30 percent of global CO2 emissions are attributable to energy consumption in buildings. In turn, heat generation accounts for around 60 percent of building energy consumption. These figures illustrate the key role to be played by sustainable, energy-efficient heating systems in the decarbonisation of buildings.
Electric heating systems, such as heat pumps, use electricity to generate heat. When powered by green electricity from wind or solar plants, these environmentally friendly systems not only help reduce the carbon footprint, they are also easy to install and maintain.
The supplementary use of heat stores and buffer systems helps compensate for fluctuations in the power grid and stabilise the heat supply in a sustainable way.

Biomass heating systems use organic materials, such as wood pellets, wood chips or agricultural waste, to generate heat. Installed in the boiler room or in a single room, these renewable heating systems not only represent an environmentally friendly alternative to fossil fuels but also help to reduce greenhouse-gas emissions.

Local and district heating systems distribute heat from central heating plants to residential and commercial units via small or extensive pipe networks. They achieve a particularly high energy yield by using the waste heat from power plants. District heating is considered ideal for densely populated areas such as cities and urban agglomerations, while local heating is intended for smaller communities and rural areas.

Modern condensing systems that use fossil fuels such as oil and gas not only burn the fuel, but also use the residual heat for maximum energy efficiency. The optimised energy yield of condensing systems is a pragmatic way of reducing greenhouse-gas emissions and cutting costs in existing buildings. Green fuels and e-fuels are promising new approaches for sustainable heat generation with liquid-based systems.
Hybrid heating systems combine fossil fuels such as oil and gas with electricity from renewable sources of energy. They are particularly suitable for heating old and existing buildings, where flexibility and efficiency are important factors when modernising heating systems. Innovative heating systems based on hydrogen and fuel cell technology also represent a promising option for sustainable heat generation in the future.
Further information about gas and liquid-based heating systemsAt ISH 2025, visitors from skilled trades, politics, the energy supply sector, property operators and building-services experts will find practical insights into all aspects of energy generation. They will also have the chance to discover the ideal energy mix for their project – efficient, sustainable and future-proof.
