Concept: Application.

The system solution for newly constructed neighbourhoods with a cold network.

A municipal area with new buildings is to be supplied via a local heating network. Buderus provides assistance with planning and implementing this "cold network". The framework conditions:

  • a new-build area completely newly constructed by the municipality
  • with 50 single-occupancy buildings (in each case, approx. 150 m²)
  • and one to two multi-occupancy buildings (in each case, approx. 2,000 m², approx. 20 residential units), with integrated shopping arcade (bakery, etc.)

Concept: Application.

The system solution for a newly constructed neighbourhood with a cold network.

Requirement:

  • heat and DHW supply via local heating network
  • consideration of the future EE65 requirement
  • investment costs and operating costs in particular are to be kept as low as possible

Concept: Functionality.

The system solution for newly constructed neighbourhoods with a cold network.

  • a "cold local heating network" with decentralised heat production through geothermal‑water heat pumps
  • the heat is recovered from the soil via a central point and distributed to all connected buildings via a ring-shaped network
  • a geothermal-water heat pump in every building ensures building heating and DHW heating

Concept: Benefits.

One network – many benefits.

  • safe fulfilment of the future legal requirements (EE65)
  • no outdoor unit necessary
  • no noise emissions outside of the building due to the geothermal‑water heat pumps
  • low drilling costs to central hole(s)
  • low operating costs due to constantly efficient geothermal‑water heat pumps
  • within the common geothermal network, the buildings mutually benefit each other through simultaneous heat supply and usage
  • individual calculation of heating costs

Concept: Business model.

Constructed by the municipality.

  • the municipality makes an advance payment and invests in the drilling for and construction of the network
  • the operating costs comprise a monthly advance payment (investment and operating costs for the network) as well as the electricity costs of the heat pumps
  • the heat pumps belong to the respective building owners
  • the property owners can conclude individual electricity contracts

PKS9 passive cooling station

  • pleasant indoor climate in summer with low power consumption
  • quick installation
  • can be connected from the top or the side

System for single-occupancy buildings: Expansion stage 1.

PKS9 passive cooling station

System benefit:
The passive cooling station makes it possible to use the heat pump to cool the rooms. In this process, the room heat is directed via the underfloor heating system to the heat pump and ultimately via the cold network to the cooler layers of earth. This form of cooling is particularly energy - efficient and resource - conserving.

System advantage:

The current generated by the photovoltaic system supplies the heat pump system and the electrical and electronic equipment in the house. Adding another battery storage system increases the proportion of own consumption and the current generated by the system itself is available independent of solar irradiation. Commissioning the photovoltaic system and integrating the heat pump system couldn't be simpler thanks to the intuitive Buderus app, MyEnergyMaster.

System advantage:
In larger buildings, freshwater stations ensure a high level of domestic hot water comfort. The heat from the buffer cylinder is directly used via the heat exchanger for DHW heating via the instantaneous water heating principle. This ensures that the highest requirements in terms of hygiene are fulfilled. Thanks to its large heat exchanger and low temperature level in the buffer cylinder, the Logaflow HSM plus WW is perfectly suitable for combining with heat pumps. In addition, it can be optimally integrated into systems with the Logamatic 5000 or a building management system, though it is also suitable for stand-alone operation.

They can be quickly installed and freely combined in a modular fashion as a multi-split unit with up to five indoor units. In addition to various comfort modes, the air conditioning systems can also be controlled on the go using the MyBuderus app.

Service: Consultation.

Consultation with regard to planning and implementation.

As an expert partner, Buderus will support you from the very beginning of the process: Even in the early stages of planning and conception for the local heat network, we will be on hand to advise you. You can also continue to rely on Buderus' expertise for subsequent stages, including implementation and system design in single- or multi-occupancy buildings.

Service: Die Erdwärmebohrer.

Die Erdwärmebohrer.

Tapping into a geothermal energy source will provide energy for decades to come. We recommend carrying out the planning and organisation in collaboration with the specialist company “Die Erdwärmebohrer”. The feasibility testing and choice of the right heat source are of highest standard, with simulation testing taking place according to the standard of a major project. This means the heat source and building are perfectly coordinated with each other.

The following steps are carried out in a geothermal project:

  1. feasibility testing, planning and offer
  2. approval process
  3. construction site preparation and scheduling
  4. implementation (drilling and connection)

The benefits of ground source heat:

  • protects the climate through high efficiency and low energy consumption
  • cost-effective cooling comfort in summer
  • when cooling: Heat storage for the winter
  • concealed and silent
  • lifetime of 50–100 years – amortisation consequently guaranteed

Planning goal of ground source heat:

An energy source that supplies energy over the course of 20 years rather than 10 is worth twice as much. Because of this, good geothermal energy planning will ensure that the drilling operations involved result in 50‑100 years' functionality, rather than 10.

In order to be able to reliably fulfil this promise, a simulation method must be used for calculation – and one that can simulate energy quantities and temperatures on a monthly basis over a period of more than 50 years.
