Application: Market environment.

The future of energy in the construction sector.

  • the demand for heat pump systems is increasing – particularly in the housing stock
  • building structures with old heating systems require flexible and future-proof modernisation options, while particularly space-saving solutions are needed in new-builds
  • desire for future-proofing and CO2-neutrality by no longer using fossil energy sources

Application: Building.

The versatile system for heat pumps in new and existing buildings.

In light of legal frameworks, such as the German Buildings Energy Act (GEG) and attractive state subsidy options, heat pumps play a vital role when it comes to selecting a heating system, both in new-builds and existing buildings. Depending on the application and building, different aspects must be considered when choosing a suitable heat pump system. A flexible choice of heat pump indoor unit allows you to optimally address different requirements and needs.

Application: Requirement.

Ideal conditions for seamless system optimisation.

  • high energy efficiency and low running costs
  • comfort and convenience
  • flexible, quick and simple planning and installation
  • optimised space requirements and an attractive design

Application: Subsidy.

Climate protection is worth it.

Renewable heating systems and efficient buildings are being promoted as part of the climate package. This includes heat pumps, pellet stoves and solar thermal systems. Benefit from state subsidies and let us advise you.

The BEG subsidy programme.

The BEG (German federal government subsidies for efficient buildings) is replacing the existing programmes from the Credit Institute for Reconstruction (KfW) and the Federal Office of Economics and Export Control (BAFA). Proven elements have been developed further and bundled into three sub-programmes, which is intended to make the subsidy programme easier to understand for citizens, companies and municipalities.

Heat pump excellence: Heat pumps in unrenovated existing buildings.

Modernising heating systems.

The existing heat distribution and heat transfer system is to be retained and operated with a heat pump that is optimised for replacing existing oil or gas boilers. In addition, it should be possible to install a photovoltaic system with an energy management system or a stove. In addition, if you consider optimising the radiators, the efficiency of the heat pump can be further increased.

Cost-conscious for improved energy efficiency.

Our house was built in 1960 and has only had some minor renovation work in the meantime. The distribution systems consists solely of radiators and we'd like to directly replace the outdated oil heating system with a heat pump. Our areas of focus are investment and running costs, as well as convenience. We'd also like to incorporate a stove into the new heating system.

Encouraging convenience. Fostering modernisations.

The selected heat pump system consists of the WLW MBE+ AR outdoor unit and the Logatherm WLW186i AR E indoor unit. The heat pump can be installed directly and operated efficiently because it is optimised for use in existing buildings with higher design temperatures. It is straightforward to integrate a stove into the heating system thanks to the versatile Logatherm WLW186i AR E indoor unit. Replacing the existing oil heating system allows you to benefit from the maximum level of subsidy.

A more efficient system. Greater independence.

The existing heat transfer system should be partially retained and partially replaced with an underfloor heating system. The outdated gas boiler is replaced with a heat pump system. The customer's attention is not only drawn to the heat pump's quiet and efficient operation, but also the opportunity to be independent from fossil energy sources.

Built in 1960. Renovated to be future-proof in 2023.

Our house was built in 1960 and we had it extensively renovated in 2023. We achieve high power coverage by reducing energy consumption in a targeted manner and adding a photovoltaic system. Our focus is on future-proofing by no longer using fossil energy sources.

Space-saving. Energy efficient. Low-noise.

The selected heat pump system consists of the WLW MB AR outdoor unit and the Logatherm WLW186i AR TP70 indoor unit. The outdoor unit is remarkably quiet and fits well in the area in front of the house. The indoor unit with an integrated buffer cylinder requires little space in a cellar and can also be used in areas with a low ceiling height. The system is monitored and controlled, and the amount of self-generated electricity used is optimised, using the MyEnergy Master app.

Increasing demands with the house efficiency standards.

In light of legal frameworks, such as the German Buildings Energy Act (GEG) and the defined house efficiency standards, heating and ventilation systems play a vital role in new-builds. While demand for a comfortable indoor climate grows, so too does the demand for self-generated electricity and environmentally friendly, future-proof systems.

Compact system solution for domestic homes made from a timber construction.

We're looking for an efficient heat pump system solution for our new home. The heating system should take up as little space as possible both internally and externally and fit in well in the surrounding area. Our areas of focus are the price-performance ratio and simple installation.
