When to install a mixing valve
• Where radiators need high temperature supply, under floors need less hot supply to make walking on it comfortable.
A mixing valve is required in a two-zone configuration with different supply temperatures per zone.
The position of the mixing valve is at the water inlet of the lowest temperature zone.
