* "Hydronic wood furnace" is the term newly adopted by the American Society for Testing and Materials (ASTM) to more accurately describe what has been called a "wood boiler." Use of the term "boiler" suggests these devices operate under pressure and produce steam for heating. In fact, most wood boilers operate under zero pressure and produce only hot water. They are sometimes referred to as an outdoor wood furnace, outside wood boiler, outdoor wood boiler, outdoor furnace, outdoor wood stove or wood heater.

** CO₂ is a major contributor to global warming. Wood releases CO₂ as it burns, but it is the same gas that would be released if the wood remained in the forest and decayed naturally. So burning wood does not increase the amount of CO₂ in the environment. Fossil fuels, on the other hand, release CO₂ that otherwise would remain buried deep in the earth.
