Size the solar expansion tank so as to ensure complete ab-
sorption of the expansion of the fluid contained within the
system, with reference to the prevailing regulations on the
matter. In particular, consider fluid characteristics, consid-
erable fluctuation of service temperature and vapour that
might be generated during solar collector stagnation stage.
Proper size of expansion tank ensures setting off of all vol-
ume changes of the heat transfer fluid, avoiding excessive
pressure increase. Limited pressure changes avoid reach-
ing safety valve opening pressure and the consequent fluid
drainage.
