Both types provide high quality heat for consistent performance. Wick chafing fuels are available in several varieties ranging in burn time and heat output. Wick fuels are considered a safer option as they are not flammable if spilled and the can stays cool to the touch when lit. Gel chafing fuels offer a strong, hot flame and are a good choice when an event lasts up to two hours. Caution should be used with gel chafing fuels: when lit the can gets very hot; if spilled, the gel will remain lit and could cause proper damage.
