| Gas | 37 % | 40.8 % |
| Heating oil | 30 % | 26 % |
| District heating | 4 % | 5 % |

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 homeowners planning renovations in Thalwil, official building register data provides crucial insights. With a median building volume of 800 m3 measured according to SIA 416 standards, owners can better estimate the scope of heating or insulation upgrades. Note that this volume data is only partially covered, representing 13 out of 1050 houses. We strongly recommend contacting the municipality early in your planning process to discuss your specific property requirements. By addressing these structural details before you begin, you ensure that your renovation budget is accurate and that your project aligns perfectly with local building standards.

Before investing in a heat pump, the first logical step is to check if your home is located in an area that can be connected to a priority district heating network.
In certain zones, authorities prioritise the development of centralised thermal networks for overall neighbourhood efficiency. Contacting local services helps clarify whether such an option is available or planned for your address.
This can significantly influence your technological choice before you start your energy renovation work.
The optimal sizing of a heat pump depends directly on the local design outdoor temperature. This technical parameter is crucial as it determines the power required to guarantee constant thermal comfort during the coldest days of the year.
An undersized unit will not heat enough, while an oversized one will unnecessarily increase investment costs and reduce overall efficiency.
Consult a certified installer to calculate the power required for your building precisely to achieve maximum thermal efficiency throughout the winter.
For outdoor air-water heat pump installations, noise management is a key factor for the neighbourhood. It is imperative to comply with applicable noise limits to preserve the quality of life in your area.
A well-considered location, the use of acoustic covers, or choosing low-noise equipment can significantly reduce the sound impact.
Take the time to study the ideal layout with your installer to avoid future conflicts and ensure a harmonious integration of your new heating system into your residential environment.
Installing a heat pump is a significant investment that requires rigorous financial planning. Using RenoIndex allows you to quickly obtain a price range in Swiss francs tailored to the specifics of your renovation project.
