This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 36 % | 27.7 % |
| Heating oil | 29 % | 21.5 % |

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.
14.9 % of buildings mix housing with shops or offices.
For your renovation plans in Herisau, the official register indicates that three buildings are under heritage protection, requiring you to contact the municipality early to navigate permit requirements. Please note that data coverage for this figure is partial. Regarding building volume, the 1736 recorded houses lack measured data according to the SIA 416 standard, making it harder to estimate the scale of heating or insulation works based on these records alone. We strongly recommend consulting local experts to assess the specific technical requirements and dimensions of your property before finalizing your renovation budget and timeline.

Solar thermal collectors usually cover much of summer hot water, providing a free and renewable energy source. By capturing solar heat, you significantly reduce the load on your primary heating system during the sunniest months.
This technology is highly effective at lowering your annual energy bills.
In addition to direct savings, you increase your property value in Herisau by improving its overall energy performance, a major asset in the current context of the energy transition in Switzerland.
Combining collectors with a heat pump needs a sizing study. It is crucial to assess your actual hot water needs and roof orientation to ensure optimal profitability. A poorly sized installation will not maximize expected energy gains.
To avoid such errors, it is advisable to engage qualified professionals who can model your consumption. Do not forget to consult RenoIndex to get a reliable cost estimate before validating any quotes with your local installers in Herisau.
Although no specific local measures are listed for Herisau, it is always recommended to check the programs in force at the cantonal level in the canton of Appenzell Ausserrhoden.
These grants aim to encourage the adoption of renewable energy and support homeowners in their transition. Ensure you submit your applications before work begins, as grant conditions often require prior approval by the competent authorities.
Planning is the most important step to ensure the success of your solar thermal project. Take the time to compare quotes from several specialized companies based in the region.
Good planning includes not only the financial aspect but also the structural analysis of your roof and the aesthetic integration of the panels. Use our RenoIndex estimator to get a clear overview of current prices and better negotiate your contracts.
Thorough preparation will save you from costly surprises and ensure a durable installation.

A well-maintained system typically lasts between 20 and 25 years. However, regular maintenance by a professional is necessary to ensure the proper functioning of hydraulic components and the efficiency of the collectors over time.
Solar thermal is primarily intended for domestic hot water production. While it can contribute to space heating as a supplement, it generally cannot replace a primary heat source, especially during the winter.
In most cases, roof-integrated solar installations only require notification to the authorities. However, always check specific regulations in the canton of Appenzell Ausserrhoden before starting your work.
