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.
7.8 % of buildings mix housing with shops or offices.
For your renovation plans in Horw, official building registry data provides essential context. Regarding heritage protection, 503 out of 523 identified buildings are classified as protected, making it critical to contact the municipality early for permit requirements. The median building volume is 1003.5 m3 based on the SIA 416 standard, which dictates the scale of your insulation and heating projects. Please be aware that data coverage is partial for volume, as only 288 out of 1067 houses are measured using this standard. Information regarding the renovation year is currently unavailable for these properties.

Solar thermal collectors convert sunlight into heat to produce your domestic hot water. These systems are highly efficient, as solar thermal collectors usually cover much of summer hot water.
The installation requires optimal orientation, ideally facing south, to maximize energy production. By integrating this technology, you significantly reduce your reliance on fossil fuels.
To get an accurate assessment of the costs involved, the RenoIndex tool provides a reliable cost range for this specific type of energy renovation project.
Integrating solar thermal energy should be considered as part of your overall heating system. It is important to note that combining collectors with a heat pump needs a sizing study.
This approach ensures that both systems work in synergy without unnecessary extra costs. A prior thermal analysis helps adjust the storage capacity and collector surface area.
RenoIndex supports you during this planning phase by providing the essential price ranges to help you budget your complete installation with confidence.
These grants can significantly reduce the initial investment while speeding up the return on investment. Do not forget to include these potential grants when calculating your final budget.
To quickly visualize the net cost of your project, use our RenoIndex tool to obtain a reliable cost estimate.
The success of your solar thermal installation depends heavily on the quality of the installation and sizing. Use certified installers who are familiar with the specifics of the canton of Lucerne.
A good professional will be able to advise you on the most suitable collector technology for your roof and your hot water needs. Feel free to request several detailed quotes to compare the services offered.

Solar thermal systems are robust and designed to last between 20 and 25 years. However, regular maintenance by a professional is recommended to ensure optimal efficiency over the years and to avoid any drop in performance due to the wear of the heat transfer fluid.
Building permit requirements may vary depending on protected zones or the type of roof. It is imperative to contact the planning department of your municipality before starting your work to obtain information specific to your property.
Yes, solar thermal energy is a profitable long-term investment. By drastically reducing your water heating bill, the savings made gradually cover the purchase cost. RenoIndex allows you to estimate your costs to accurately calculate your expected return on investment.
An east or west orientation can also work with a slight decrease in efficiency. Higher-performance collectors or a larger surface area can compensate for this deficit. Consult a certified installer to assess the actual energy potential of your specific roof.
