How energy efficient is a water heater that burns wood pellets?

An EPA-certified water heater or stove burns wood pellets at 70 to 83 percent efficiency, states the U.S. Department of Energy. Since the EPA also asserts that the higher the efficiency rating the lower the amount of toxic emissions and the safer the appliance, such a rating is highly efficient.

Compressed wood pellets are made from sawdust, a sustainable and renewable source. As an alternative fuel choice, they are highly efficient in combustion and heating, saving on costs and energy for end-users. In addition, the carbon-neutral fuel helps to reduce carbon emission by producing very little air pollution, making it the cleanest of solid residential fuels.
