Renovations, heritage and volumes
For your renovation projects in Ittigen, the RegBL figures provide vital context regarding your property. Currently, data coverage for house volume and renovation years is only partial, which limits automated estimation capabilities. Although official records indicate no heritage-protected buildings, we strongly advise contacting the municipality early to confirm permit requirements. Since the volume for the 840 recorded houses does not follow the SIA 416 standard, you will need to provide precise measurements when planning your thermal insulation or heating upgrades. Accurate site-specific data remains essential for determining the scope and budget of your renovation.

How solar thermal works
Solar thermal systems rely on collectors on your roof that absorb solar rays to heat a heat-transfer fluid. This liquid then transfers energy to a storage tank.
In Switzerland, solar thermal collectors usually cover much of summer hot water, reducing the load on your main boiler. This simple and sustainable solution increases the value of your property in Ittigen while lowering your carbon footprint.
When integrated intelligently into existing or new heating systems, it provides a reliable and efficient way to manage your home's thermal needs.
Sizing and system integration
The success of a solar installation depends on rigorous sizing. It is necessary to evaluate your real hot water needs and the available roof surface.
Combining collectors with a heat pump needs a sizing study to ensure both systems work in optimal synergy without energy waste. A poor configuration could limit efficiency gains.
We recommend consulting professionals to analyze your roof layout and the specific energy needs of your home before starting work, ensuring your installation performs at its absolute best for years to come.
Available grants and incentives
Although no specific rules have been enacted by the municipality of Ittigen, owners should check the current cantonal programs in the canton of Bern. These financial aids can vary depending on the chosen technical performance.
It is crucial to submit your subsidy application before the official start of work. Check the canton's official energy portal to find out the eligibility criteria and current amounts.
Tips for your renovation
For a successful project, favor a comprehensive approach. Solar thermal installation is often more cost-effective when it accompanies a renovation of the building envelope, such as thermal insulation.
Also, consider maintenance : a well-maintained system will last longer and be more efficient. To get a clear idea of the budget required, use the RenoIndex calculator.

Frequently asked questions
Does solar thermal work in winter in Ittigen?
Yes, the system works as long as there is radiation, even in cold weather. However, performance is reduced compared to summer. It acts as a supplement to the main heating system, which takes over to ensure a constant temperature in your hot water tank throughout the colder months.
How much roof area is needed?
It depends on your hot water needs and your roof's tilt. Generally, a few square meters are sufficient for a standard family. A sizing study by a professional is recommended to optimize the orientation and tilt of the collectors to maximize annual solar yield for your home.
How long does an installation last?
A quality solar thermal installation has an average lifespan of 20 to 25 years. Regular maintenance, about every 5 years, allows for checking the heat-transfer fluid and mechanical components, ensuring that your system remains high-performing and reliable over the long term for your household.
Can solar and heat pumps be combined?
Yes, this is an excellent combination. Solar thermal covers hot water demand during sunny months, allowing the heat pump to focus on space heating. This synergy optimizes the lifespan of your equipment and significantly reduces your overall energy costs.
