This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 8 % | 5.6 % |
| Heating oil | 47 % | 32.1 % |
| District heating | 16 % | 10.7 % |
| Heat pump | 23 % | 7.8 % |
| Electricity | 2 % | 40.3 % |
| Wood | 4 % | 2.1 % |
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.
6.4 % of buildings mix housing with shops or offices.
For homeowners in Obersiggenthal, the building registry data provides essential guidance for planning renovations. With 370 buildings under heritage protection, it is vital to contact the municipality early to navigate permit requirements for any exterior work. Regarding project scale, data coverage is currently partial; the measured volume according to SIA 416 standards is unknown for all 1022 houses, and the renovation year is not recorded. Consequently, owners should prioritize a professional site inspection to assess heating and insulation needs accurately, as these specific official figures are not available to support standardized planning or preliminary budget estimates.

Solar thermal collectors capture energy from the sun to heat a fluid circulating to a storage tank. These systems usually cover much of the hot water demand during the summer, reducing the load on your main boiler.
Although sunshine varies, this technology remains a proven solution to supplement existing heating systems. It is essential to choose durable materials adapted to your roof to ensure optimal performance over the long term throughout the year.
Use our expert resources to evaluate your roof's suitability early in the process.
A successful project requires a precise analysis of your household's actual hot water needs. Combining collectors with a heat pump, for example, needs a sizing study to ensure efficient synergy.
Incorrect calibration could lead to summer overheating or insufficient coverage in winter. Consult specialists to validate the compatibility of your installation.
RenoIndex allows you to estimate the costs associated with these technical adjustments before contacting local companies, providing a reliable budgetary basis for your work.
Investing in solar thermal energy is a commitment to the energy transition. Several cantons subsidise collectors per m² or per installation to encourage sustainable renovation.
It is recommended to check the specific conditions for grants in force when submitting your application. Rigorous financial planning is the key to optimizing your investment.
By using our RenoIndex estimator, you can access a cost range in CHF, allowing you to better anticipate the net cost after deducting potential aids.
A well-maintained system guarantees stable thermal production for decades. It is advisable to periodically check the hydraulic circuit, the heat transfer fluid pressure, and the condition of the collectors.
This preventive maintenance prevents performance losses and ensures the long-term viability of your investment. By staying informed about best practices, you maximize the energy savings generated by your installation.
For any further renovation steps, RenoIndex remains your ally in estimating the necessary costs and keeping your home up to current standards.

Generally, solar water heating serves as a supplement. It effectively covers hot water needs in summer, but a backup energy source is required during winter or periods of low sunshine to ensure continuous thermal comfort.
Using the RenoIndex simulator is entirely free. It allows you to quickly obtain a price range in Swiss francs for your energy renovation projects, helping you better budget for your work.
Planning regulations depend on cantonal and municipal legislation. We recommend contacting your local authority to check if a preliminary declaration is required for your specific project.
