Morphology

heater = heat (transparent) = heat + er

A heater is straightforwardly something that heats, so the meaning follows the usual agent/instrument noun pattern with -er.

Etymology

The word heater comes from the simple word heat ('to make warm') plus the ending -er, which means 'one that does something'. So a heater is literally 'a thing that makes warm', which is why we use it to warm rooms or water.
