What happens when a solution of concentrated HNO3 and H2SO4 are heated?

I know the reaction goes: HNO3 + H2SO4 ↔ NO2+ + HSO4- + H2O

But does anything change when it is heated?

4HNO3 = 4NO2 + O2 + 2H2O

I didn't mean nitric acid on its own, basically what happens when you heat: NO2+ + HSO4- + H2O?
