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.
6.4 % of buildings mix housing with shops or offices.
For renovation projects in Wohlen, RegBL data shows that out of 3190 registered buildings, 693 are under heritage protection, necessitating early consultation with the municipality regarding permits. Regarding building volume, data coverage is partial, with only 29 buildings measured according to the SIA 416 standard, showing a median of 920 m3. These volume figures are vital for determining the scope of heating or insulation works. Please note that the renovation year is not available for this municipality, preventing analysis based on building age. We recommend using these official figures as a foundation while acknowledging the specific limitations in current data coverage.

A well-maintained system generally has a lifespan of 20 to 25 years. Periodic checks every few years by a professional help ensure the proper functioning of the hydraulic circuit and control system, thus ensuring optimal performance throughout the entire lifespan of your equipment.
In winter, solar radiation is weaker, which reduces yields. However, the solar thermal system still contributes to preheating cold water, thus relieving your main heating system. It never completely replaces heating in winter, but effectively complements your hot water production during sunny days.
Tilt and south orientation are ideal, but other configurations remain possible. The condition of your roof should also be checked before installation. It is strongly advised to have a feasibility study carried out by a professional installer to validate the compatibility of your building with thermal technology.
