Taking that as a princible, the volume of the system's water increases along with the temperature increase in the closed circuit heating & cooling systems. As the increasing water volume can not be compressed, the excess of the water has to be compansated into the closed curcuit system. For this reason, the most common way to compensate the excess of the water is to add an expansion tank to the system.
