Step 2: Assessment and Preparation
Step 2: Assessment and Preparation
Before starting the installation of the solar water heater, a feasibility study is essential to assess your hot water needs, and installation options according to the configuration of your property and the particularities of the location considered.
- Firstly, make sure you obtain the necessary planning permission, as some areas may impose restrictions on the installation of solar water heaters.
- Second, plan technical details such as tank capacity, the optimal location of solar collectors, and the choice between a forced circulation or thermosyphon system. This is also the ideal time to assess your project’s profitability, considering installation costs and potential grants or financial aid.
Step 3: Preparing the Plumbing System
After determining the specifics of your solar water heater installation, it will be necessary to prepare your plumbing system for its integration. This step involves organizing the circulation of water between the solar collectors, the storage tank, and your domestic hot water network. Previously obtained planning permission must be taken into account during this preparation. Our partner installers, experts in solar water heaters, are at your disposal to support you in this technical phase and ensure that everything complies with current standards.
Step 4: Installing the Solar water heater Collectors
Following validation of the quote and preparation of the plumbing system, the actual installation can begin. This step covers the installation of solar thermal collectors by a plan drawn up by professionals. These sensors are responsible for capturing solar energy to heat water. To guarantee optimal efficiency, it is recommended to orient the sensors towards the south with an inclination of approximately 30°. The duration of this installation can vary from a few days to several weeks, particularly if the sensors are integrated into the roof or installed on a specific structure.
Step 5: Integration with the plumbing system
Essential to ensure the distribution of hot water in your home, this step consists of connecting the solar water heater to your domestic plumbing network. It may be necessary to carry out specific work to guarantee optimal circulation of water between the solar collectors, the hot water tank, and the drawing points in your house. Our partner technicians ensure that this integration is carried out according to current standards and that the system is ready to operate efficiently. For a system solely dedicated to self-consumption, that is to say for your use without selling surplus energy, this step is essential to guarantee a continuous supply of hot water.
Focus on storage solutions for solar water heaters:
Depending on the specifics of your solar water heater project, it may be necessary to store heated water during sunlight hours for later use. In this context, thermal storage tanks are an ideal option for optimizing the use of your solar water heater. It is crucial to emphasize that the effectiveness of these storage systems is highly dependent on the configuration and needs of each household. They are particularly suitable for homes with significant hot water needs or irregular periods of sunshine
Currently, two main storage solutions are commonly used:
- Classic thermal storage tanks: These tanks store the water heated by solar collectors for later use. They are commonly used in most solar water heater installations.
- Combined tanks: These systems combine the solar water heater with another heating source (such as a boiler or heat pump). They ensure a supply of hot water even when there is insufficient sunlight.
It is essential to choose the storage system adapted to your needs to maximize the benefits of your solar water heater.
Step 6: Commissioning the solar water heater
After integrating with the plumbing system and checking all connections, your solar water heater is ready to be activated. Once the certificate of conformity has been received (similar to the CONSUEL certificate for electrical installations), it is essential to carry out a series of tests to guarantee the proper functioning of the system. Our partner technicians ensure the correct commissioning of the installation so that you can fully benefit from your solar hot water. Also be sure to take the necessary steps with your water supplier, if required, to report the addition of a solar water heater to your home network.
