Renovations, heritage and volumes

For renovation planning in Riehen, RegBL figures reveal that 1031 out of 4255 buildings are under heritage protection. If your property is classified, you must contact the municipality early to navigate permit requirements. Regarding house volume, data coverage is partial; the standard SIA 416 volume measurement is not recorded for the 2885 houses listed, complicating the assessment of scale for insulation or heating projects. Additionally, the year of last renovation is not available in the registry. Homeowners should account for these missing metrics when estimating project costs and technical specifications for their specific building.

Benefits of solar thermal

Solar thermal collectors usually cover much of summer hot water, significantly reducing your dependence on fossil fuels or electricity. By utilizing direct radiation, these systems allow for efficient thermal production.

To maximize the lifespan of your system, it is recommended to engage qualified professionals for the sizing and installation of components.

Regular maintenance ensures that the heat transfer fluid circulates without loss of efficiency, guaranteeing consistent performance throughout the year.

Sizing and compatibility

Integrating a solar thermal system into an existing home requires rigorous analysis. Combining collectors with a heat pump needs a sizing study to avoid conflicts in thermal regulation.

The choice between flat plate or vacuum tube collectors will depend on your roof surface and actual hot water needs. A preliminary simulation helps validate the most cost-effective scenario.

RenoIndex assists you in this step by providing a clear estimate to budget your renovation work effectively.

Managing grants

It is recommended to regularly check the assistance available at the cantonal level before validating your quote. These financial supports can reduce the initial cost of your energy renovation project.

Keep in mind that any application must be submitted before the start of work to be eligible for potential cantonal funding.

Installation and planning

The success of your project relies on structured planning. Start with a technical feasibility study of your roof: orientation, slope, and lack of shading are crucial. Once the system is sized by an expert, installation work is usually quick.

Ensure you obtain all necessary permits before the work begins.

For effective budget management, use the RenoIndex online estimator, which provides an indicative price range for your solar thermal installation, allowing you to move forward confidently with your renovation project.

Frequently asked questions

What is the lifespan of a solar thermal system?

A well-maintained solar thermal system can operate efficiently for 20 to 25 years. Regular maintenance, including checking the heat transfer fluid and the control system, is essential to maximize this longevity and ensure optimal hot water production over the long term.

Does solar thermal work in winter?

Yes, solar thermal collectors work in winter, even in cold weather, as they capture solar radiation. However, efficiency is lower due to shorter daylight hours. The system is therefore generally coupled with a backup source such as a boiler or a heat pump.

What permits are needed in Riehen?

It is imperative to check with the municipal administration of Riehen regarding local zoning regulations. Although most solar installations are encouraged, certain protected areas or listed buildings may require special authorization to preserve the architectural landscape.

How can I estimate the cost of my project?
