This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 4 % | 3.2 % |
| Heating oil | 41 % | 26.5 % |
| District heating | 4 % | 4.3 % |

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.
12.4 % of buildings mix housing with shops or offices.
For renovation planning in Arth, RegBL figures provide vital guidance despite partial data coverage. With a median volume of 889 m3 across the 50 buildings measured per SIA 416, this figure helps determine the scale of necessary heating or insulation upgrades. Out of 2039 total buildings, heritage status is known for 74, with 2 buildings officially protected. If your property is classified under these records, contacting the municipality early is essential. Heritage status significantly impacts permit requirements, so early engagement ensures your renovation plans comply with local preservation regulations and helps streamline the approval process for your specific project.

Solar thermal collectors capture energy from the sun to heat a transfer fluid, which then delivers this heat to your water tank. These systems are particularly effective during sunny months.
Solar thermal collectors usually cover much of summer hot water, significantly reducing the load on your main boiler. Proper orientation, ideally facing south, is essential for optimal performance.
This solution is ideal for private homes looking to improve energy efficiency by harnessing natural resources, thereby reducing reliance on conventional heating systems throughout the warmer seasons.
Integrating solar thermal systems with a heat pump is an effective strategy for comprehensive energy renovations. However, combining collectors with a heat pump needs a sizing study to ensure compatibility.
A qualified installer must ensure that both systems work in harmony to prevent overheating or control conflicts. A properly sized installation prioritizes solar heat, reserving the heat pump for cooler days or increased demand.
This approach maximizes the lifespan of your equipment while optimizing your overall electricity consumption for year-round efficiency.
It is recommended to research current programs before finalizing any quotes. Switching to solar thermal heating increases your property value while reducing your carbon footprint.
To get a clear view of potential costs and savings, use our RenoIndex estimator, which is specifically designed to support your renovation decisions and budget planning.
To ensure the success of your project, obtain multiple quotes from qualified local companies. Always check the installers' certifications and their experience with solar systems.
Consider long-term maintenance, as a well-maintained system lasts significantly longer. It is also advisable to view the installation as part of a holistic building renovation, including insulation, to maximize energy savings.

Yes, it works even in cold weather if the sun is shining. However, the output is significantly lower than in summer due to reduced solar radiation. It then serves as a pre-heating system for your hot water.
A quality, well-maintained solar thermal installation can last between 20 and 25 years. Regular maintenance is recommended to ensure the optimal performance of the hydraulic circuit throughout its service life.
Whether a permit is required depends on local guidelines and the visual impact on your roof. It is advisable to contact your local municipal authorities before starting any work to ensure compliance.
Installation requires technical skills in plumbing and electricity, as well as work at heights. It is strongly recommended to hire a certified professional installer to ensure the system is safe and efficient.
