About the Heat black outline icon
Three tall wavy lines rise in parallel from a flat surface drawn as a shallow open bracket, the shorthand for warmth radiating off a hot object. No flame or sun is shown, so it stays neutral enough for cooking, weather and machinery. Use it on oven and stove controls, HVAC and thermostat screens, weather widgets, hot-surface warning labels and spa or sauna pages.
The three waves are evenly spaced and identical in height, each curving twice, which keeps the mark balanced; the base line anchors them with short upturned ends. Pairs with steam, snowflake and thermometer icons. Thin strokes need at least 24px.
This is the black outline version of the heat icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
