  We perform a statistical combination of the ATLAS and CMS results for the
search of a heavy resonance decaying to a pair of vector bosons with the
$\sqrt{s}=8$ TeV datasets collected at the LHC. We take into account six
searches in hadronic and semileptonic final states carried out by the two
collaborations. We consider only public information provided by ATLAS and CMS
in the HEPDATA database and in papers published in refereed journals. We
interpret the combined results within the context of a few benchmark new
physics models, such as models predicting the existence of a
{\ensuremath{\mathrm{W^\prime}}\xspace} or a bulk Randall-Sundrum spin--2
resonance, for which we present exclusion limits, significances, $p$-values and
best-fit cross sections. A heavy diboson resonance with a production cross
section of $\sim$4-5 fb and mass between 1.9 and 2.0 TeV is the exotic scenario
most consistent with the experimental results. Models in which a heavy
resonance decays preferentially to a WW final state are disfavoured.
