Obtain heat using a solar thermal installation (solar heating)

To produce heat, you need to settle the following equipment:

• Solar Sensors. These are panels settled on your roof that capture the sun's radiation to turn it into heat. They act as solar boilers.
• Storage balloon. It is a tank that stores the heat produced and is supplied by a network of piping ensuring the junction with the solar collectors.
• Back-up energy. In most cases, an additional source of energy is needed to ensure that heat production meets your needs, regardless of the season and the level of sunshine. The heat relay can be provided by an independent system (fireplace, stove, electrical resistance, etc.). It can also be provided by a system coupled to your solar installation. The additional production is then ensured by a traditional boiler.
• Regulator. It makes it possible to manage the solar thermal production of the panels. It prioritizes solar energy over back-up generation devices. In the event of a lack of sunlight, it modulates the supply of additional energy to maintain an optimal temperature. When the production of the system exceeds your actual consumption, it controls possible overheating of the panels.

Heat production can be used for the following purposes:

• Heating domestic hot water
• Ensure the production of heating
• Combine the 2, if your installation allows it.
