This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 2 % | 2.1 % |
| Heating oil | 24 % | 23.6 % |
| District heating | 3 % | 2.6 % |
| Heat pump | 42 % | 24.8 % |

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 Ruswil, RegBL data provides essential yet partial insights. Out of 1363 buildings, 383 are listed under heritage protection, necessitating early coordination with the municipality to secure the required permits for any exterior changes. Regarding building volume, data following the SIA 416 standard is limited, with only three houses measured at a median of 1130 m3, while the majority remains unmeasured or recorded under other standards. Use these figures to gauge the scale of your insulation or heating projects, and always consult local authorities to confirm the specific regulatory requirements for your property.

Solar thermal collectors capture energy from sunlight to heat a fluid circulating towards a storage tank. In summer, these systems perform exceptionally well and usually cover much of your domestic hot water needs.
This is a sustainable solution to reduce your dependence on fossil fuels. Before starting, ensure your roof's orientation and tilt allow for sufficient sunlight throughout the year.
A well-planned installation maximizes the energy yield, making it a highly effective investment for your home's long-term energy efficiency.
Integrating solar thermal systems must be considered holistically within your heating setup. It is common to combine collectors with a heat pump to maximize energy savings.
However, combining collectors with a heat pump needs a sizing study performed by a qualified professional. Such analysis ensures both systems work in harmony, avoiding unnecessary overloads and ensuring optimal temperature management.
Correct sizing is essential to prevent technical issues and maximize the lifespan of your equipment while providing consistent performance year-round.
These grants aim to reduce your initial investment costs significantly.
To get a clear view of your overall budget, including potential financial support, use our RenoIndex tool to simulate your renovation costs reliably and for free, ensuring you have all the necessary information for your project.
A successful installation depends on meticulous planning and choosing competent local partners. In Ruswil, hire certified installers familiar with the local climate conditions.
Also, check the state of your thermal insulation before installing solar panels, as reducing energy needs is the first step toward an efficient home. Once your project is ready, be sure to request several quotes to compare offers.

Solar thermal is ideal for hot water but rarely sufficient to cover all heating needs during winter. It is usually used as a supplement to a main system like a heat pump, providing a highly efficient hybrid solution throughout the year.
With regular maintenance, a solar thermal installation can last between 20 and 25 years. It is recommended to have hydraulic components and the heat transfer fluid checked every few years to ensure optimal performance and avoid drops in efficiency.
Whether a permit is needed depends on the scale of the work and the building zone. It is recommended to contact the local building department or your architect to verify applicable regulations before starting the installation on your roof.
Yes, solar collectors also capture diffuse radiation, even on cloudy days. Although efficiency is lower than on a sunny day, the system continues to preheat water, saving energy on the operation of your main boiler.
