Modernising an apartment building inexpensively
Apartment house modernisation
In terms of environmental protection, the landlord considers using the roof of the building to install an additional solar heating system. The building already has adequate thermal insulation. This is a good basis for being able to operate the future heating system at low cost. Furthermore, the owner looks at having a ventilation system installed during the modernisation project.
Reasons for choosing the new technology
The old appliance has reached the end of its useful life after almost 20 years and will simply be replaced with the new condensing boiler. The solar thermal technology on the roof supports the heating boiler. This cuts fuel consumption and reduces harmful emissions.
If the output of the solar modules is sufficient, it can cover all DHW heating in the summer. This means that the oil heating boiler could remain switched off during this period. Furthermore, the landlords can apply for subsidies for installing renewable energy technologies.

Positive effects even without changing the system
As this example shows, even a modest modernisation project that does not change the entire heating system can have noticeably positive effects. Especially if the developer integrates additional modern and ecological components and creates a hybrid system in this way. This can be best achieved by obtaining all components from a single supplier so that they can be optimally combined with one another.
