Is it necessary to install a hot water/cold water mixing valve at the outlet of a DualSun water tank?

Current building codes in France require the installation of a hot/cold water mixer at the outlet of solar tanks, so YES we recommend the installation of a mixing valve at the output.

However it is worth noting that this device is not necessarily essential in DualSun devices, because with lower stagnation temperatures than traditional solar thermal, DualSun tanks never exceed 65°C.
