Bump up your wood stove's efficiency a bit with a Caframo Ecofan. Designed for use with cast iron stoves, the fan requires no electrical hook-up. Instead it relies on temperature differentials atop your hot wood, pellet or gas stove to set those blades into motion.
By generating 150 cubic feet per minute of air flow, the fan will make your wood stove 14 percent more efficient, says the manufacturer.
