This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 38 % | 39.1 % |
| Heating oil | 18 % | 15 % |
| District heating | 11 % | 9.4 % |

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.
10.1 % of buildings mix housing with shops or offices.
For your renovation planning in Winterthur, data from the federal building register (RegBL) provides useful insights despite partial coverage. The median building volume of 692 m3 helps estimate the scale of heating or insulation works, though this figure represents only a small portion of the 8665 registered houses. Regarding heritage protection, there are 2823 buildings with known status, though none are currently marked as protected. Given the limited nature of these statistics, we strongly recommend contacting the municipal authorities early in your planning process to verify specific local regulations or heritage constraints before proceeding with any construction projects.

Solar thermal collectors are valuable allies for your energy efficiency. They usually cover a large portion of your hot water needs during the summer, reducing the strain on your main boiler.
To maximize this profitability, it is crucial to properly size the collector surface according to your actual consumption. Remember to check the orientation and tilt of your roof in Winterthur.
A south-facing exposure is ideal to ensure optimal production throughout the year. Use the RenoIndex calculator to estimate the costs associated with your specific project.
If you already own a heat pump, integrating solar thermal collectors is possible but demanding. Combining collectors with a heat pump needs a sizing study performed by a professional.
This hybrid system helps preserve the heat pump during sunny periods and increases the lifespan of your equipment. The choice of components must be consistent to avoid efficiency losses.

Investment in renewable energy is encouraged by various authorities in Switzerland. Several cantons subsidise collectors per m² or per installation.
Although specific rules may evolve, it is recommended to inquire about available support in the canton of Zurich before starting your work. These incentives significantly reduce the payback period.
To get a clear view of your net expenses after subsidies, the RenoIndex calculator provides an estimate of the total costs tailored to your situation in Winterthur.
The success of your project relies on rigorous planning. Before any installation in Winterthur, ensure you assess the condition of your roof and your insulation. A well-insulated house makes better use of the collected solar heat.
Always work with certified installers who are familiar with local and cantonal requirements. A well-designed system ensures lasting savings on your energy bills.
Do not forget to consult the RenoIndex calculator to get a realistic price range for your solar thermal project. This free tool helps you anticipate your budget and move forward with your renovations with peace of mind.

A well-maintained solar thermal system generally lasts between 20 and 25 years. Periodic maintenance of the heat transfer fluid and mechanical components ensures optimal performance throughout this period.
Yes, solar thermal works very well thanks to diffuse radiation. Even in cloudy weather, the collectors capture energy. They are particularly profitable in summer for hot water production, thereby reducing your energy costs.
The technical installation is complex and requires plumbing and electrical skills. To benefit from subsidies and ensure the system's safety, it is highly recommended to hire a qualified professional.
