| Gas | 37 % | 27 % |
| Heating oil | 18 % | 20.4 % |
| District heating | 1 % | 0.6 % |

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.
13.6 % of buildings mix housing with shops or offices.
For your renovation plans in Wädenswil, the federal building register provides important insights for your project. The median house volume is 497 m3 according to the SIA 416 standard, which is essential for scaling heating and insulation works. Please note that this volume data is based on a very limited coverage of only two buildings out of 2128. Regarding heritage status, 53 buildings are identified as known. We recommend contacting the municipality early to clarify any specific permit requirements or restrictions for your property, ensuring that your renovation project proceeds smoothly while respecting the local building regulations.

Solar thermal collectors usually cover much of summer hot water. To maximise your energy efficiency in Wädenswil, the annual solar coverage rate should be assessed based on your roof's orientation.
During winter, solar radiation is weaker, necessitating a boiler or another backup system to guarantee a constant temperature. A well-sized installation can significantly reduce your energy bills throughout the year.
Do not hesitate to simulate the overall costs via RenoIndex to better understand the initial investment required for your home renovation project.
Combining collectors with a heat pump needs a sizing study. This hybrid approach allows you to leverage solar heat for preheating water, while the heat pump takes over during cold spells.
It is crucial to harmonise the components to avoid summer overheating and ensure system longevity. Proper sizing ensures your investment is not unnecessarily overvalued while still meeting your household's needs.
To obtain a budget range specific to your situation, please consult the free RenoIndex estimator for reliable guidance on current market prices.
Several cantons subsidise collectors per m² or per installation. It is advisable to inquire about available grants within the canton of Zurich before beginning work. These incentives can vary depending on the size of your installation and performance criteria.
These grants help reduce the payback period for your equipment.
To refine your financial calculations and incorporate these elements into your renovation budget, use our RenoIndex tool to generate a comprehensive estimate of the costs for your solar installation project.
Investing in solar thermal systems is a major advantage for reselling or renting out your property in Wädenswil. In addition to meeting modern energy requirements, this type of renovation improves the building's energy rating.

The duration depends on the complexity of the roof and the system. Generally, you should allow a few days for mounting the collectors on the roof, followed by a few days for the technical interior connection.
In Wädenswil, inquire with the competent municipal authority. Integrated solar installations are often simplified, but a notification or permit may be required depending on the type of building.
Yes, solar thermal collectors also capture diffuse radiation. Production is certainly lower than in direct sunlight, but the system continues to heat water, assisted by your boiler.
The cost depends on the number of panels and the hot water tank volume. Use our free RenoIndex estimator to get a price range tailored to your renovation project.
