Energy transition
Decarbonisation starts at home
Buildings are among the largest consumers of energy and account for a significant share of CO2 emissions. In Europe, around 40% of final energy consumption is attributable to the building sector, particularly for space heating and hot water. The transition to environmentally friendly heating technologies therefore represents a key lever for decarbonisation. At the same time, greater use of domestically generated renewable energy reduces Europe’s reliance on energy imports. With efficient products and services, the Vaillant Group contributes to the success of the energy transition.

The building sector: a key lever for the energy transition
(as of 2024)
Why modern heating systems are crucial
Decarbonising the building sector is only possible by transforming heat supply – moving away from fossil fuels and towards technologies such as heat pumps that use renewable energy.
The technology is already available:
Heat pumps make use of free, highly efficient ambient heat, for example, from the air, the ground, or groundwater.
Photovoltaic systems generate electricity directly on site.
Energy storage systems ensure that energy from renewable sources can be used later.
Digital energy management systems connect all components and optimise the operation of the heat pump – delivering even greater efficiency and lower emissions. When needed, the heat pump parameters are adjusted automatically, reducing energy consumption and costs by up to 15%.
The interaction of these systems makes households less dependent on fossil fuels and sustainably lowers operating costs. In this way, property owners benefit from reduced energy expenses while maintaining a high level of comfort. At the same time, it represents an investment in maintaining and increasing the value of the property.

Taking care of a better climate
Bringing comfort and sustainability together: products from the Vaillant Group make a significant contribution to decarbonising the building sector – both in new builds and in the energy-efficient refurbishment of existing buildings.
A key focus is on the use heat pumps. They operate using around 75% renewable energy, requiring only about 25% electricity to run. If this electricity comes from renewable sources, the system operates entirely emission-free. This makes heat pumps a key technology for the decarbonisation of the building sector towards climate neutrality.
Gas-fired condensing boilers can also be integrated into hybrid systems alongside renewable technologies. In addition, the latest generation of Vaillant condensing boilers can already run on up to 20% hydrogen. For units up to 30 kW, a conversion kit is available to enable operation with 100% hydrogen.

Modern heating technology as a key to decarbonisation
The framework for decarbonisation is defined by global climate agreements and the EU’s target of achieving climate neutrality by 2050. As an interim milestone, CO2 emissions in the European Union are to be reduced by 55% by 2030.
Significant renovation needs in existing building stock
With its “Renovation Wave”, the EU aims to support the achievement of these goals and accelerate the modernisation of existing building stock. The objective is to at least double the renovation rate to 2% of buildings per year by 2030.
A key focus is the replacement of outdated, inefficient heating systems. Modern, high-efficiency technologies such as heat pumps play a pivotal role in sustainably reducing both energy demand and CO2 emissions.
