About the Heat Waves Hot Surface black outline icon
Three wavy lines rise in parallel from an open, tray-like base drawn as a flat bottom with two short upturned sides. The shapes read as heat radiating from a hot surface, steam, warmth and rising temperature. Fits oven and cooktop controls, HVAC and thermostat apps, car seat heater interfaces, food safety labels and climate slides.
Equal spacing and matching S-curves make the heat lines read as movement, while the wide base grounds them and suggests a pan or warming plate. Pair it with thermometer, fan and snowflake controls. Use at 24 px or larger so the waves stay distinct.
This is the black outline version of the heat waves hot surface icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
