As expected for its age, the building only has poor thermal insulation. The building needs a high standard of thermal insulation to cut energy costs significantly. To this end, all exterior walls and the roof will be fitted with new thermal insulation. The owners also want to have the old windows and exterior doors replaced with modern elements with low heat transfer coefficients. These structural measures alone are very costly but worthwhile in the long run.
The owners decide to convert from the old oil heating system to a modern heat pump heating system for the following reasons. They also want to install a controlled mechanical ventilation system.
Modern appliances are produced from high-quality materials. They require little maintenance and work very efficiently. In addition, heat pump heating systems do not need to be connected to a chimney and so can be positioned almost anywhere in the building. Moreover, the system under consideration has a compact design that takes up very little space.
The models in question are environmentally friendly as they do not consume any fossil fuels or produce exhaust gases that are harmful to the climate.
If the electricity needed to run the heat pump heating system is obtained from renewable sources, the ecological footprint is better yet.
The cost of fossil fuels will rise over the next few years as a result of the CO2 tax alone, quite apart from the normal fluctuations of market prices. In contrast to heating systems based on fossil fuels, modern heat pump systems minimise operating costs.
A modern ventilation system can lower the heating costs still further. They use the heat contained in the extract air to prewarm the supply air via a heat exchanger so no heat is lost.
Furthermore, the entire project is eligible to receive a state subsidy.

It is possible to switch to heating with environmental heat even in older apartment blocks if the structural requirements are met. Modernisation involves a considerable investment. In the long term, these expenses will be recouped as heating requirements are cut and the owners are no longer subject to the rising cost of fossil fuels.
When combined with a controlled mechanical ventilation system, comfort is improved by the generation of a pleasant, healthy indoor environment. Once the owners have a sufficient budget available again, they want to install a photovoltaic system on their roof. There is ample space available to generate the electricity required for the heat pump heating system. Thus, the operating costs will drop still further.
