Units that cost less but are not energy efficient may cost more to operate in the long run.

Operators have the option of choosing from a number of energy efficient rotisserie features.

Units with multiple burners offer the ability to utilize only those that are needed, cutting down on gas use. Batch units with forced air burners create a higher velocity of oxygen and gas, which can provide as much as 35 percent energy savings.

Newer spit designs include gas heat that cooks food from the inside out. This not only helps kill bacteria, but can increase yield and shorten cooking times. On some units, a self-cleaning feature will help keep convection fans clean, which can decrease cooking times and provide energy savings.
