Size the solar expansion tank so as to ensure complete
absorption of the expansion of the fluid contained within
the system, with reference to the prevailing regulations
on the matter. In particular, consider fluid character-
istics, considerable fluctuation of service temperature
and vapour that might be generated during solar col-
lector stagnation stage. Proper size of expansion tank
ensures setting off of all volume changes of the heat
transfer fluid, avoiding excessive pressure increase.
Limited pressure changes avoid reaching safety valve
opening pressure and the consequent fluid drainage.
