British and Australian slang for a storage heater — those bulky electric units that soak up cheap off-peak electricity overnight and slowly release warmth through the day. The name 'heat bank' makes perfect sense: it stores thermal energy like a bank stores money, releasing it when you actually need it. Common in older UK and Australian homes, especially rentals or properties without gas central heating.

The heat bank in the hallway had been charging all night, so the flat was actually warm when we got up.
