This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 43 % | 22.7 % |
| Heating oil | 20 % | 10.3 % |
| District heating | 6 % | 2.9 % |

Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
For your renovation plans in Aarau, federal building register figures are vital. With 467 buildings under heritage protection, it is crucial to contact the municipality early to address permit requirements. The median house volume is 800 m3, which serves as a key indicator for scaling insulation or heating upgrades. Please note that data coverage regarding volume is partial, as only 20 houses were measured according to the SIA 416 standard. We recommend verifying the precise dimensions of your specific property before starting any works to ensure your renovation budget remains accurate and effective for your project.

The first step is to assess your building's energy needs. First check whether your area can connect to a priority district heating network, as this option is often preferred in urban zones.
Furthermore, the local design outdoor temperature determines the heat pump capacity needed to heat your interior efficiently during cold spells. A professional thermal study is essential to avoid costly oversizing.

Installing an air-water heat pump involves adding an outdoor unit. These devices must strictly meet noise limits towards neighbours.
When choosing the location, be careful to direct the airflow to minimize noise pollution, especially if the facade is near property boundaries. Complying with these guidelines helps maintain good relations with neighbours.
If you have doubts, our experts at RenoIndex can help you anticipate these technical constraints.
Subsidies evolve regularly according to cantonal climate goals. It is recommended to submit your application files before starting any renovation work.
For a clear view of your investment, compare your projected expenses with the estimates provided by RenoIndex.
A successful installation relies on choosing a certified installer who can integrate the heat pump into the existing distribution system, such as underfloor heating or low-temperature radiators.
Once installed, commissioning allows for the adjustment of operating parameters based on your actual consumption. Regular optimization ensures a longer lifespan for your equipment.
