Solar thermal energy relies on collectors installed on your roof to heat a fluid, which then transfers its energy to a hot water storage tank.
Solar thermal collectors usually cover much of summer hot water, which significantly eases the burden on your main heating system. It is a sustainable and eco-friendly solution.
Before proceeding, ensure that your roof's orientation and tilt are optimal to maximize efficiency. A preliminary study helps confirm the technical feasibility for your specific building.
It is often beneficial to combine solar thermal with other systems, such as heat pumps. However, combining collectors with a heat pump needs a sizing study.
The goal is to ensure perfect synergy between both components to avoid summer overheating and guarantee maximum efficiency in winter. Well-sized components increase the lifespan of your installation and optimize your long-term savings.
A qualified professional can analyze your specific hot water needs to suggest the most efficient setup.
The energy transition is encouraged at various levels. Several cantons subsidise collectors per m² or per installation. It is advisable to consult the current cantonal programs in the canton of Zurich to identify available grants.
These subsidies can significantly reduce your initial investment. Always remember to submit your applications before starting the work, as grants are generally not retroactive.
Check the specific technical requirements imposed by the authorities before purchasing equipment to ensure your eligibility.
A well-installed solar thermal system requires little maintenance, but periodic checks are recommended to maintain optimal performance. Checking the heat transfer fluid and the integrity of the collectors ensures consistent production over many years.
Hire certified installers familiar with local requirements. Good preventative maintenance allows you to detect potential wear of components early.
By scheduling these checks, you ensure the longevity of your system while keeping your energy savings at a high level throughout the year.
