EFFICIENCY & ECONOMY Exhaust emissions are less than one gram per hour, which means that the pellet fuel is almost completely burned. Moreover, the heavy-duty heat exchangers installed in all products provide up to 83% efficiency to ensure that heat is transferred into your house quickly. Today, when alternative energy sources are expensive, this efficiency translates into a very low cost to heat your home. EASE OF OPERATION All Enviro Fire heating products come with the largest full pedestal ash pans available. Easy clean out ports and burn pot liners add to the low maintenance requirement of our products, and the specially designed air wash system keeps the door glass cleaner, even at low burning settings. As an added bonus, the flow of air through the heat exchanger and the exhaust system is carefully controlled to make all Enviro Fire heating products the quietest available.
