Three wavy vertical lines rising to suggest heat or steam
About the Heat Wavy Lines black outline icon
Three sinuous vertical strokes curve upward side by side, each tapering at the top the way rising heat or steam distorts the air.
There is no flame or thermometer, so the mark stays neutral enough for warmth, vapor and aroma alike. Use it for thermostat and smart home controls, oven and kettle appliance panels, weather widgets, spa or sauna listings, and hot food menus.
This is the black outline version of the heat wavy lines icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
