Morphology
The meaning of 'sun heater' is directly compositional: 'sun' (the star providing light and heat) modifies 'heater' (an appliance producing heat), so a heater that uses the sun/solar energy is easily inferred. This noun+noun compounding pattern is common cross-linguistically and follows regular English attributive modification, so a B1 learner who knows both constituents will readily understand it.
Etymology
Sun heater The noun sun heater comes from systems that use the real sun to make heat: roof panels or tubes catch sunlight and warm water or air inside. That's why a sun heater means a device that uses 'sunlight' to provide heat for water or rooms.
