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.
7.4 % of buildings mix housing with shops or offices.
For homeowners planning renovations in Goldach, official register data shows that 27 buildings out of 1 561 are under heritage protection, while the status remains unknown for 1 456 others. It is essential to contact the municipality early regarding permits to avoid complications. Furthermore, data coverage is partial for building volume according to the SIA 416 standard, with 991 houses having unknown or non-standardized measurements. This lack of specific volume data makes it more difficult to accurately determine the scale required for comprehensive insulation or heating renovation projects, so professional on-site verification is highly recommended for your planning.

Solar thermal collectors capture radiation to heat a heat transfer fluid. This system is particularly effective at covering a large portion of your hot water needs during the summer season.
In winter, although yields are lower due to reduced sunlight, it remains a valuable support for the boiler. It is important to note that these installations require optimal tilt and orientation to maximize energy performance.
An analysis of your roof is therefore the first essential step before ordering any equipment.
Integrating solar thermal into your current installation must be considered holistically. If you plan to couple your collectors with a heat pump, a rigorous sizing study is necessary to ensure compatibility between systems.
Incorrect calibration could lead to summer overheating or winter inefficiency. It is advisable to hire a qualified professional to assess your real needs based on your household size.

High-quality solar thermal systems are designed to last between 20 and 25 years. Regular maintenance of the hydraulic circuit and heat transfer fluid is essential to ensure this longevity and maintain the optimal efficiency of your panels in the long term.
Generally, solar thermal acts as a supplement to an existing system rather than a total replacement. It efficiently covers hot water needs in summer but requires a boiler or heat pump to take over during periods of low winter sunlight.
In Switzerland, regulations vary depending on protected areas and municipal specificities. Although many solar installations are simplified today, it is imperative to consult your municipal authority before starting work to verify local requirements.
