This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 45 % | 37.6 % |
| Heating oil | 17 % | 12.7 % |
| District heating | 11 % | 8.3 % |

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.
11.8 % of buildings mix housing with shops or offices.
For your renovation plans in Lenzburg, official building registry data provides vital insights. With 219 buildings listed under heritage protection, it is essential to contact the municipality early to clarify permit requirements. The median building volume is 820 m3, a figure based on 6 buildings measured according to the SIA 416 standard, indicating that data coverage is partial for this metric. Understanding these values helps you accurately assess the scale of your planned heating and insulation upgrades, ensuring you approach your renovation project with the correct regulatory expectations and realistic dimensional estimates from the start.

Solar thermal collectors usually cover much of summer hot water, leading to a significant reduction in your fossil energy consumption. By using free sunlight, you gain energy independence for your home in Lenzburg.
Beyond financial savings, you actively contribute to environmental protection by lowering your CO2 emissions. It is a long-term investment that adds value to your property.
To evaluate the realistic cost of your equipment and its payback, consult the RenoIndex estimator and get a reliable estimate in CHF right away.
The success of a solar water heating installation depends on a rigorous study of your hot water needs. Combining collectors with a heat pump needs a sizing study to ensure optimal synergy between systems.
An incorrectly sized system can lead to summer overheating or winter inefficiency. It is recommended to hire certified professionals capable of modeling your annual energy output.
RenoIndex supports you in this process by providing a clear price range in CHF for your project, tailored to current Swiss standards.
This financial support can significantly reduce your initial investment. It is crucial to submit your application before work begins, as grants are generally not retroactive.

A well-maintained solar water heating system guarantees increased longevity and consistent energy performance. It is advisable to have the heat transfer fluid and circuit pressure checked every few years by a specialized technician.
This inspection prevents efficiency losses due to component wear. In Lenzburg, as elsewhere in Switzerland, regular maintenance also allows for the early detection of potential leaks or pressure drops.
