Renovations, heritage and volumes
For renovation planning in Thun, official registry data identifies 4 heritage-protected buildings. If your property falls under this category, contact the municipality early to navigate permit requirements. Regarding building volume, the median is 914 m3 according to the SIA 416 standard; however, this figure covers only 5 houses out of 3587, representing a highly partial data set. Because recorded data for the year of renovation is unavailable for the local building stock, homeowners cannot rely on these statistics to determine the age of their property's last significant upgrades or specific energy efficiency needs.

How Solar Thermal Works
Solar thermal collectors capture solar radiation to heat a heat transfer fluid circulating towards a storage tank. This system is particularly efficient during sunny months. In practice, solar thermal collectors usually cover much of summer hot water.
To optimize the efficiency of your installation, the orientation and tilt of the panels must be carefully studied according to your roof.
Annual maintenance is recommended to check the fluid pressure and the condition of the components, thus ensuring optimal performance over the long term. To assess the budget needed for such an installation, consult the free RenoIndex estimator.
Compatibility with Other Systems
Integrating solar thermal into an existing heating system is often a wise move to improve overall energy ratings. However, combining collectors with a heat pump needs a sizing study.
The goal is to ensure that both energy sources work in complementarity without creating regulation conflicts. Proper sizing allows you to make the most of solar gains while using the heat pump only when necessary.
Remember that a well-designed installation helps extend the lifespan of your main equipment. To obtain a cost estimate for your project while considering these aspects, use the RenoIndex tool.
Grants and Financial Support
It is imperative to check with the competent authorities in the canton of Bern before starting work, as grant conditions may vary. A prior application is often required to benefit from available subsidies.
By combining these grants with the energy savings generated by the system, you significantly reduce the payback period. Do not hesitate to use our RenoIndex estimator to obtain a precise estimate of the net cost after potential subsidies.
Planning and Successful Installation
The success of a solar thermal project relies on an installation performed by qualified professionals. During planning, it is crucial to analyze your actual hot water needs based on the size of your household.
Local installers in Thun will be able to advise you on the best possible location and the collector technology adapted to your roof. An installation compliant with Swiss standards guarantees not only safety but also access to cantonal subsidies.
Take the time to compare the offers received to get the best value for money. Finally, keep in mind that RenoIndex is at your disposal to estimate the costs of your work for free.

Frequently asked questions
Can solar thermal replace my heating system?
No, solar thermal is a complementary solution. It mainly covers hot water needs but requires a boiler or heat pump for space heating and to maintain temperature during the winter.
How much panel area is needed?
The necessary area depends on your daily hot water consumption and the number of inhabitants. Generally, allow between 1 and 1.5 m² per person for a standard installation optimized for domestic hot water.
Is maintenance expensive or frequent?
Maintenance is simple and infrequent. A check every 3 to 5 years is usually enough to monitor the heat transfer fluid and the condition of the pump. It is a minor cost compared to the savings achieved.
Is it profitable in the Thun region?
Yes, thanks to the sunlight and the subsidies available in the canton of Bern, the system becomes profitable quickly, especially with the long-term rise in the price of fossil fuels.
