  We study the Bose-Einstein condensation of a gas with $SU_q(2)$ symmetry. We
show, in the thermodynamic limit, that the boson interactions introduced by the
quantum group symmetries enhance Bose-Einstein condensation giving a
discontinuity in the heat capacity $C_v$ at the critical temperature $T_c$. The
critical temperature and the gap in $C_v$ increase with the value of the
parameter $q$ and become approximately constant for $q>3$.
