Solar thermal energy uses solar radiation via collectors installed on your roof. These heat a heat transfer fluid that transfers the energy to a storage tank.
Solar thermal collectors usually cover much of summer hot water, reducing reliance on traditional heating systems during the warmer season. It is an ecological and sustainable solution for making the most of well-exposed roofs.

Integration and sizing
The success of a solar installation depends on careful sizing. Combining collectors with a heat pump needs a sizing study to ensure optimal efficiency throughout the year.
An incorrectly calibrated system can lead to overheating in the summer or insufficient performance in the winter. It is advisable to consult a qualified professional to carry out a full thermal study of your building.
RenoIndex helps you anticipate this work by providing an overview of the budgets required for such equipment in the canton.
Subsidies and financial aid
Although rules vary, it is crucial to inquire about current programs before starting work. To find out potential amounts in the canton of Aargau, check current conditions with the relevant authorities.
Do not forget to consult RenoIndex to estimate costs and better prepare your subsidy application.
Maintenance and longevity
Once installed, solar thermal systems require periodic maintenance to ensure their longevity and performance. This includes checking the heat transfer fluid, circuit pressure, and the condition of the collectors.
Regular maintenance prevents performance drops and extends the life of your investment by several years. Ensure that you include maintenance costs in your budget.

Frequently asked questions
Can solar thermal replace my boiler?
Solar thermal is generally used as a supplement to a main heating system to produce hot water. It cannot completely replace a boiler, especially in winter, but it significantly reduces your annual energy consumption. Use RenoIndex to estimate your potential savings.
How much collector area is needed?
The surface area required depends on the size of your household and your hot water needs. In general, you should allow for 1 to 1.5 m² of collectors per person. A professional technical study is needed to define the exact sizing.
How long does a system last?
A well-maintained solar thermal system has an average lifespan of 20 to 25 years. Regular maintenance by a specialist ensures that your installation maintains its optimal performance throughout this period.
Can I install solar in winter?
It is technically possible to install collectors in winter as long as weather conditions allow safe work on the roof. It is even a good time to plan your work before spring arrives. Check your needs with RenoIndex.
