Definition
Noun: A hot-water tank is a household appliance that heats and stores water for domestic use. It consists of an insulated tank with a heating element (either electric or gas) that maintains water at a set temperature, ready for use in sinks, showers, and baths.
Usage
The term "hot-water tank" refers specifically to the complete unit that both heats and stores water. It is a common fixture in residential buildings.
Examples

- We need to replace our old hot-water tank because it's no longer energy efficient.
- A leak from the hot-water tank caused some water damage in the utility room.
Advanced Usage
- "Hot-water tank" vs. "Water heater": In many contexts, "water heater" is a more common synonym. However, "hot-water tank" can specifically emphasize the storage aspect, distinguishing it from "tankless" or "on-demand" water heaters that do not store a volume of hot water.
