Morphology

water + heater

The meaning 'a device that heats and stores water' is directly and transparently derived from combining 'water' (the liquid) with 'heater' (an appliance that produces heat). This noun–noun compound follows a common compositional pattern present across languages, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Water heater comes from the simple picture of water and heater: a machine that warms and often stores hot water. Imagine a metal tank or small unit that makes hot water for your taps and showers, so the name means 'a device that makes hot water for your home'.
