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.
11.3 % of buildings mix housing with shops or offices.
For your renovation projects in Altdorf, official building registry data provides vital insights. Regarding heritage protection, 3 buildings are officially listed, meaning you must contact the municipality early to secure necessary permits, noting that data coverage for this indicator remains partial.

Solar thermal collectors capture energy from the sun to heat a fluid circulating to a storage tank. These systems usually cover much of summer hot water requirements for households.
Optimising efficiency requires a careful assessment of your roof's orientation and tilt. In Switzerland, rigorous sizing is necessary to prevent overheating during summer months.

A well-maintained solar thermal installation can operate efficiently for 20 to 25 years. Regular maintenance by a professional ensures that hydraulic components function correctly and the heat transfer fluid remains in good condition, guaranteeing long-lasting performance.
Yes, collectors still work in winter if the sun is shining. However, output is reduced due to shorter days and lower solar intensity. The system must therefore be supplemented by an auxiliary heat source to ensure consistent comfort throughout the colder months.
Generally, solar installations on roofs are subject to a prior notification procedure with municipal authorities. It is essential to check zoning rules or potential restrictions regarding historic buildings before starting any construction work to ensure compliance with local regulations.
Solar thermal is designed to heat domestic water and can support space heating, but it cannot fully replace a boiler. It must always be coupled with a primary heating system to guarantee hot water and heating supplies all year round.
