This layout is recommended for heating installations with wide operating water flow variations (radiator thermostatic
valves present in the system). Minimum system volume is guaranteed by a mixing tank (2). Take care when calculating
the volume of water in the installation and only take account of 50% of the mixing tank's volume.
Example: For a useful volume of 70 litres the actual mixing tank volume will be 140 litres.
