Morphology
The meaning 'a temperature at which an object becomes visibly red from heating' is directly derivable from combining 'red' (the color) with 'heat' (high temperature); the phrase describes heat sufficient to cause a red glow. This simple adjective+noun compositional pattern is transparent and cross-linguistically accessible, so a B1 learner who knows both constituents would likely infer the intended meaning.
Etymology
The noun red heat comes from the simple image of metal glowing red from strong heat when it is very hot. Blacksmiths used that red colour as a sign the metal was hot enough to shape, so 'red heat' means the temperature when an object becomes visibly red and easy to work.
