Morphology
The phrase 'heat energy' is a direct compositional combination of 'heat' (thermal energy or energy transfer due to temperature difference) and 'energy' (usable power), so its meaning — energy in the form of heat or transferred because of temperature difference — is directly inferable from the constituents. This scientific collocation follows normal noun+noun composition and has clear equivalents in many languages, so a B1 learner who knows both words would readily understand it.
Etymology
The compound heat energy is a simple name: it is the energy that comes from heat, the warm feeling that moves from something hot to something cold. So, it means the 'energy' that moves from hot to cold and makes things warmer.
