*Why is the BTU indicated on the EPA label different than the one advertised?
You will notice a difference between the BTU output indicated on the unit's white EPA label
affixed to the glass and the BTU advertised on our web site and/or product literature. The
maximum BTU output we advertise for this unit is what will be obtained with a full load of
seasoned cordwood inserted inside the firebox. The EPA output, on the other hand, is
what has been obtained during emissions testing. The EPA test procedure requires that a
special type of wood be used and positioned inside the firebox in a manner that does not
represent the way the firebox volume would normally be utilized using seasoned
cordwood. The EPA test load is typically much smaller. Hence, the BTU as per the EPA
label is reduced. The BTU output that should be considered by a normal user is the one
we advertise for seasoned cordwood.
**What is the efficiency of this model?
First, it is important to mention that the efficiency calculation is not mandatory in North
America. Manufacturers who have tested their appliances to the EPA Standard must
report a "default" efficiency on the little white EPA tag that must be affixed to the stove.
This is why you will normally see a 63% efficiency rating on that EPA tag. The real
efficiency of EPA-certified units, however, is normally between 70% and 80%. It is possible
for manufacturers to test their appliances for efficiency. Manufacturers that report an
efficiency rating higher than 63% have probably had their appliances tested through an
independent laboratory. Although there exists more than one recognized efficiency
calculation method, the one normally used by North American manufacturers is the
Canadian CSAB415.1 method. Our appliances have all had their efficiency tested per that
method. You will notice that the vast majority of our appliances have an efficiency rating
between 70% and 80%, as indicated on the yellow tag affixed to the appliance's glass. We
are of the opinion that EPA-certified appliances with an efficiency rating within that range
will provide an equivalent performance. In other words, when you are considering the
purchase of one of our EPA-certified appliances and you hesitate between two models,
their efficiency rating should not constitute your number one criteria. First, make sure that
you select an EPA-certified appliance. Then, concentrate on the features that matter the
most to you, such as the look, the size of the firebox, the warranty, etc. Please note that
the use of a blower is always recommended to improve air circulation. This will also
optimize your efficiency.
