The heat pump for the whole neighbourhood
SOLUTIONS FOR HEAT SUPPLY ACROSS ENTIRE DISTRICTS
For more than 25 years, we have been developing solutions around heat pumps. For district solutions, we look at the heat supply of entire residential areas and combine heat pumps with suitable heating networks and energy sources.
What is a district solution?
A district solution involves planning the heat supply for several buildings together. Heat pumps can be used for heating, cooling and domestic hot water and connected via a shared heating network.
Depending on the project, additional energy sources such as photovoltaics, solar thermal energy, geothermal energy or waste heat can also be integrated.
- At least 30 residential units are planned and realized together and a common heat network is established
- Heat pumps can be used for heating, cooling and domestic hot water
- Other renewable energies, such as photovoltaics or solar thermal energy, can be used and distributed to different households
- Several residential units can be supplied via a coordinated heat supply concept
- A range of concepts with centralized or decentralized heating systems are possible – perfectly matched to your respective requirements
- Comfort temperatures can be set individually in each residential unit – despite using a shared heating network
- The use of local heat and heat pumps significantly reduces the consumption of fossil heat carriers or makes it possible to dispense with them completely.
- Depending on the supply concept, the use of fossil energy sources can be reduced or avoided
- This ingenious supply concept is rewarded by the state and the funding for such projects is higher than ever before
- We reduce primary energy demand with our heat pumps and energy concepts
Living of the future
Today, according to the building ordinance, the provision of heat in a new building or renovation project must involve more than 50% renewable energy. In the future, the mandatory requirements under the Building Energy Act (GEG) will have an even more significant influence on the share of renewable energies in thermal energy supply in the new construction sector. In addition, the requirements for thermal insulation of the building envelope are increasing, which is leading to a decrease in the primary and final energy demand. Synergy and efficiency potentials must be tapped via neighborhood solutions according to the Building Energy Act (BEG), the CHP and/or PV tenant power supply amendment, and climate protection legislation at the state and federal government level.
Heat supply in the neighbourhood with cold district heating
Heat pumps can be integrated into cold district heating networks. The comparatively high heat-source temperatures and low flow temperatures of modern surface heating systems can support efficient heat pump operation.
In district concepts, heat pumps can use different heat sources and help reduce or replace fossil energy sources for heating and cooling.
DECENTRALISED SYSTEM - ONE OR MORE HEAT PUMPS IN EACH RESIDENTIAL UNIT
- Compulsory connection for the homeowner
- The house resident pays a monthly levy
- The heat pump belongs to the operator (contractor, municipality, etc.)
- Simple scaling
- Cooling is possible
- economical
- energy advantageous
Advantages of a district solution.
- Contribution to meeting climate targets
- Individual temperature control for each residential unit
- Higher rental revenues
- Long-term customer loyalty through heat supply contracts
- Monitoring and remote maintenance possible
- Operator receives full subsidy (BAFA, Wärmenetz 4.0, KfW 271)
- Special energy concepts (electricity surplus – electricity purchase)

Project planning at a glance
1. ESTABLISHMENT OF A COMMON HEAT NETWORK
In the case of district solutions, several residential units are planned and built together and a common heating network is set up at that time.
2. DETERMINATION OF THE HEAT SOURCE
Suitable heat sources include:
- Deep drilling
- Springs
- Ground collectors
- Waste heat
3. DEFINITION OF THE HEAT SUPPLY CONCEPT
Various concepts are possible for the heat supply – perfectly matched to your requirements.
- Cold local heating network with decentralized heat generators
- Local heating network with centralized heat generators
