This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 29 % | 27.2 % |
| Heating oil | 40 % | 25.4 % |
| District heating | 7 % | 5.9 % |

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.
23.8 % of buildings mix housing with shops or offices.
For your renovation plans in Rorschach, the official register indicates that 23 of the 1065 buildings are under heritage protection, necessitating early consultation with municipal authorities regarding permit requirements. Regarding building volume, data coverage is partial as there are no recorded SIA 416 standard measurements for the 280 houses identified, which complicates the estimation of heating or insulation project scales. Since there is no median renovation year provided, you lack historical context on recent updates. Homeowners should conduct a thorough site assessment to determine the true condition of their property and plan necessary renovations based on specific structural needs.

Solar thermal collectors capture the sun's energy to heat a heat transfer fluid that then transfers this heat to a storage tank. These systems are extremely efficient during the summer, usually covering a large part of your household's hot water needs.
Beyond financial savings, you increase the value of your property while actively contributing to the Swiss energy transition.
For a detailed price analysis, do not hesitate to use our RenoIndex tool, which will provide you with a price range adapted to the local Swiss market.
The installation of thermal panels integrates perfectly with other heating systems. If you already use a heat pump, combining these technologies is an intelligent solution, but it requires a rigorous sizing study.
The goal is to ensure the solar system effectively complements your main heat source without unnecessary oversizing. Careful planning maximizes the annual yield of your installation.
RenoIndex supports you in this process by offering clear visibility on installation costs, allowing you to compare the options available for your home.
It is advisable to contact your cantonal authorities to learn about the specific terms. Although the rules vary, these grants significantly reduce your initial investment.

The payback period depends on the initial cost, energy savings achieved, and grants received. Generally, thanks to reduced heating and hot water bills, the return on investment occurs over several years. RenoIndex can help you estimate the initial costs.
Yes, solar collectors work even in winter, though their efficiency is lower due to reduced sunshine. They primarily serve as support for heating or hot water preparation but often require an additional heat source during very cold days.
Solar thermal installations are robust and designed to last a long time. On average, they are estimated to last between 20 and 25 years with regular maintenance. This represents a sustainable investment for your home while helping to reduce your carbon footprint.
The need for a permit depends on local legislation and the building's appearance. It is recommended to contact your local planning department to verify if your project requires a formal authorization before beginning the work.
