How HeatGenie Compares
HeatGenie’s approach to self-heating is unlike other self-heating systems familiar to the food and beverage industry. Previous self-heating technologies involved mixing quicklime or other chemicals with water. With the highly efficient solid-fuel system used in the HeatGenie system, consumers will enjoy a larger serving size of product in a lighter, fully-recyclable package. Heating times are four to six times faster and the heater itself is eight times more compact than earlier self-heating systems. As an example, a one ounce HeatGenie heater can be used to heat eight ounces of coffee from room temperature to serving temperature in less than two minutes.
