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.
7.9 % of buildings mix housing with shops or offices.
For your renovation plans in Villmergen, official register data provides essential guidance. With 385 buildings out of 1639 under heritage protection, contacting the municipality early is crucial to secure necessary permits. Regarding building scale, the median volume is 600 m3 across 1225 houses. However, please note that coverage is partial as only 23 houses have been measured according to the SIA 416 standard. This limited data set means you should carefully verify your property's dimensions when planning major insulation or heating upgrades to ensure your renovation budget remains accurate and reflects your building's specific requirements.

Solar thermal collectors capture solar radiation to heat a fluid circulating towards a storage tank. In summer, these systems perform well and usually cover a large part of your hot water needs.
This is a robust solution for reducing dependence on fossil fuels. To get a cost estimate for your installation, use the free RenoIndex estimator.
Rigorous planning ensures optimal efficiency throughout the year, even if output decreases slightly during the less sunny winter months.
It is common today to pair solar thermal with a heat pump. This combination achieves excellent overall energy performance.
However, be careful : combining collectors with a heat pump requires a careful sizing study to avoid temperature conflicts and maximize equipment lifespan.
Our experts recommend using the data provided by RenoIndex to correctly calibrate your budget from the start. A properly sized system guarantees not only constant thermal comfort but also optimized long-term financial profitability.
It is advisable to check current programs before signing any quotes. For a clear view of your total investment, RenoIndex helps you get a reliable price range.
Keep in mind that these grants are often subject to specific technical conditions, such as compliance with certain building insulation standards or performance criteria for the installed system.
Choosing your technical partner in Villmergen is crucial for the durability of your solar installation. A qualified professional will be able to assess your roof orientation and calculate the number of panels required.
Use RenoIndex to have a concrete basis for discussing average market costs before requesting quotes. Prioritize local companies that know the specificities of the canton of Aargau.

A well-maintained solar thermal system usually lasts between 20 and 25 years. The heat transfer fluid and electronic components may require occasional maintenance. Use RenoIndex to estimate initial costs and plan a budget for regular maintenance to ensure maximum performance over the long term.
Generally, properly integrated roof solar installations are subject to a notification procedure at the cantonal level rather than a full building permit. However, it is recommended to contact the relevant municipal authorities to confirm the specific requirements for your building according to the rules in force in the canton of Aargau.
Solar thermal is primarily used to produce hot water. While it can contribute to room heating, it generally cannot cover 100% of needs in winter. For a realistic estimate of your overall project, consult RenoIndex and consider a hybrid solution or one combined with a heat pump.
