We present a novel set of high-precision lattice results for the equation of state of the SU(2) pure Yang-Mills theory in the confining phase. The prediction of a gas of non-interacting, massive glueballs yields a remarkable description of lattice data, provided that a bosonic closed string model is used to derive an exponentially growing Hagedorn spectrum for heavy glueball states. This effective model can be applied also to the SU(3) Yang-Mills theory and describes with great accuracy lattice results reported by Borsányi et al. in JHEP 07 (2012) 056.
