Cumberland Stove Works' with Tri-X Heat Control is the result of extensive research, proving to be the world's first true Multi Fuel Pellet Stove in the alternative fuel and heating market. The MF3700 Multi Fuel Pellet Stove is not only the first true multi fuel stove, it is more efficient than its competitors.

The graph to the right shows how much heat goes up the stack in other stoves, and how little heat is lost up the MF Series stack. That preserved heat is, of course, sent into the room instead. The MF Series stove is 82% efficient. That's an amazing level of efficiency and we're proud to offer it to you.
