This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 30 % | 23.1 % |
| Heating oil | 33 % | 26.9 % |
| District heating | 4 % | 3.9 % |
| Heat pump | 25 % | 12.8 % |
| Electricity | 5 % | 29.6 % |

| Solar thermal | 0 % | 1.3 % |
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.
13.5 % of buildings mix housing with shops or offices.
For renovation planning in Zofingen, official register figures provide essential insights. With 361 out of 2293 buildings listed under heritage protection, homeowners must contact municipal authorities early to navigate permit requirements. The median building volume is 1464,5 m3, serving as a critical metric for scaling heating system upgrades or insulation works. Please note that data coverage is partial, as only two buildings are measured according to the SIA 416 standard. Additionally, as no renovation year data is available, homeowners should rely on independent surveys to assess the current technical state of their properties before initiating any project.

Solar thermal collectors are an efficient solution for harnessing the sun's free energy. They allow you to heat your sanitary water with high efficiency, especially during sunny months.
In Switzerland, solar thermal collectors usually cover much of summer hot water, thereby reducing the demand on your main heating system.
It is a sustainable investment that increases your property value while protecting you against the future rise of energy costs related to fossil fuels.
The success of your solar installation depends on rigorous sizing. It is necessary to analyze your actual hot water needs to avoid oversizing or undersizing your system.
If you plan to add this technology to an existing installation, note that combining collectors with a heat pump needs a sizing study by a professional.
This step ensures optimal synergy between the equipment and extends the overall lifespan of your hot water production system.
Several cantons subsidise collectors per m² or per installation to encourage energy transition. These grants may vary according to current cantonal regulations.
It is essential to submit your grant application before starting the work, as funding is generally not granted retroactively.
Once your solar thermal system is installed, regular maintenance is the key to ensuring its performance over the long term.
Although these installations are robust, periodic checks of the heat transfer fluid, pressure, and electronic components of the control station are necessary.
Annual or biennial maintenance performed by a qualified heating technician helps detect potential drops in yield or early wear. A well-maintained system will maintain high efficiency for several decades while ensuring your safety.

Most solar installations are subject to a simplified notification procedure. Always check with the competent authorities if any restrictions related to heritage protection apply to your specific building before starting any installation.
Yes, they capture diffuse radiation even in winter. However, the output is lower due to reduced sunlight duration and low temperatures. They generally serve as a supplement to the main heating system during this period.
A solar thermal installation is designed to last between 20 and 25 years. Regular maintenance by a professional helps maximize this lifespan and ensures optimal efficiency throughout its operational cycle.
