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.
10 % of buildings mix housing with shops or offices.
For renovation projects in Uster, RegBL data provides useful benchmarks for planning. With a median building volume of 640 m3, homeowners can better estimate the scale of heating or insulation upgrades. Note that data coverage is partial, as only 40 out of 2948 buildings are measured according to SIA 416 standards. Regarding heritage protection, no protected buildings are recorded among the 376 known entries, though the overall coverage remains limited. We advise you to contact the municipality early to confirm your property status and specific regulatory requirements before finalizing your renovation plans or submitting any permit applications.

Solar thermal systems transform solar radiation into heat. Collectors installed on your roof capture energy to heat a heat transfer fluid that circulates to a storage tank. Solar thermal collectors usually cover much of summer hot water.
To ensure optimal efficiency, it is advisable to check the orientation and tilt of your roof. A well-sized system maximises annual output, thus reducing your dependence on fossil fuels.
Before starting, compare available solutions with the RenoIndex estimator to visualise your potential investment in CHF.
Integrating solar thermal energy into an existing heating system is increasingly common. Combining collectors with a heat pump needs a sizing study.
This hybrid approach allows you to cover hot water needs in summer thanks to the sun, while the heat pump takes over during less sunny months. This strategy optimises the lifespan of your main equipment by avoiding short cycles.
For a reliable estimate of the budget required in CHF for such an installation, consult the free RenoIndex service.
Investment in renewable energy is encouraged by various measures. Several cantons subsidise collectors per m² or per installation, which can significantly reduce the initial cost of your solar project in Uster.
It is recommended to enquire with the canton of Zurich about current subsidy programmes before signing any quotes. These grants aim to accelerate the energy transition for private buildings.
Do not forget to use the RenoIndex estimator to get an overview of costs in CHF, including potential savings from available grants.
A successful solar thermal project requires careful planning. Start by assessing the condition of your roof and its insulation. A solar system is most effective on a well-insulated building. Then, hire certified professionals for sizing and installation.
In Uster, as elsewhere, the quality of components plays a key role in long-term performance. Do not hesitate to obtain several comparative quotes to refine your budget.

No, solar thermal is mainly intended for domestic hot water production. It acts as a complement to your existing heating system to reduce your overall energy consumption. You will still need a primary energy source for periods of low sunlight or for space heating.
A well-maintained solar thermal system typically has a lifespan of 20 to 25 years. Regular maintenance by a professional helps ensure the proper functioning of pumps and the quality of the heat transfer fluid over the long term.
In general, rooftop solar installations are subject to a simple notification procedure, but it is imperative to check the local regulations of the city of Uster. Certain protected areas or historical buildings may require more specific administrative steps.
In winter, efficiency is lower due to reduced sunlight and shorter days. However, solar collectors remain active on clear days. The system is cost-effective over the full year, offsetting the winter dip with high production during the summer months.
