Technical integration

Installing thermal panels is more than just placing collectors on your roof. For optimal performance, combining these collectors with a heat pump requires a rigorous sizing study.

This analysis ensures perfect compatibility between the different technologies and avoids system overheating. Correct sizing guarantees constant thermal comfort throughout the year.

Tips for your renovation

A successful solar thermal project requires methodical planning. Beyond the choice of materials, your roof configuration and panel orientation play a crucial role in final energy yield.

Considering comprehensive energy renovation work often leads to efficiency gains far superior to an isolated installation. We advise you to consult experts to validate technical feasibility before making any purchases.

Frequently asked questions

What is the lifespan of a thermal installation?

A well-maintained solar thermal installation can operate efficiently for 20 to 25 years. It is advisable to have the heat transfer fluid and pumps checked regularly to ensure that the initial energy efficiency of your system is maintained over the long term.

Can solar thermal heat the whole house?

In Switzerland, solar thermal is ideal for domestic hot water but generally serves as a supplement to heating in winter. A combination with a heat pump allows for efficient heating of the entire building during the cold seasons.

Do I need a building permit?

In general, roof-integrated solar installations are largely facilitated. However, it is necessary to inquire with your local authority in Birmensdorf before starting any work to confirm the requirements in force.

How can I get a price estimate?
