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.
10.1 % of buildings mix housing with shops or offices.
For your renovation plans in Kreuzlingen, the building register shows that out of 3101 buildings, only 3 are under heritage protection, making early contact with local authorities essential in these specific cases. Regarding building volume, the median is 780 m3 according to SIA 416, though this figure is based on a partial sample of 7 houses out of 1659.

Solar thermal collectors capture sunlight to heat a heat-transfer fluid, which then transfers its heat to your hot water.
During the summer period, these systems usually cover a large part of your hot water needs, allowing your main heating system to remain switched off.
It is a particularly effective solution for single-family homes looking to optimize their energy self-consumption while benefiting from an abundant and renewable resource that is available throughout the year.
If you want to combine your solar collectors with a heat pump, a rigorous sizing study is essential. A correctly sized installation ensures that both systems work in perfect synergy, avoiding unnecessary operating cycles.
It is advisable to consult qualified professionals to assess your roof and your actual needs. Poor planning can reduce the overall efficiency of the system.

Yes, solar thermal collectors work even in winter thanks to diffuse radiation. However, production is significantly lower than in summer. They generally act as a supplement to the main heating system, reducing the load on your boiler during sunny days, even when it is cold.
A well-maintained solar thermal installation generally has an average lifespan of 20 to 25 years. Regular maintenance, including checking the heat transfer fluid, ensures this longevity and maintains optimal efficiency throughout the life of your equipment.
The need for a building permit for solar panels depends on specific cantonal and municipal regulations. It is strongly recommended to contact the local administration in Kreuzlingen before starting work to check whether a prior declaration or a permit is required for your project.
Profitability depends on your household's hot water consumption and the sunlight on your roof. Solar thermal is most profitable in households that use a lot of hot water. Use the RenoIndex calculator to assess the costs and determine if this solution is suitable for your specific situation.
