Good point on your part. Alot of "efficiencies" to look at but never stated in layman terms. Going by your interpretation of that verbiage, the ash that is left over is the other 1%? How then is that 99% versus the missing 1% interpreted? Do they weigh it and say that minus the moisture, the weight of firewood used was 100 lbs and the ash weighed 1 lb? I always expected a fire to consume everything it could and the rest was ash. Is this woodboiler a new concept to that age old fact? Actually in that ash is also heat retention.
I, in no way am a scientist or able to contest the manufacturers claims. However, if you want to sell a product - then compare it to your competition before I'll be impressed or convinced to buy. Rhetoric is for the judicial system - just give me something to compare it to. I have no argument with your interpretation however.

I'm trying to compare it. This is the best I have because I'm also not aware of any manufactures who actually post their actual test results online for everyone to see like we have on our website (most just try and say efficient without any proof like my car gets great gas mileage until I buy it and it actually doesn't). We have documented proof...
I saw a PGS Caddy EPA forced air furnace (probably the next best we have seen) manual on their website and it has the following:
Average emissions rate: 6.56 g/hr
Average heating efficiency: 71.43%
Compare that with ours:
.45 Gr/Hr. Emmission
99.4% Combustion Efficiency
99% Smokeless Burns
84% Overall Efficiency
Any particular reason you are not EPA certified?
Here is where many people are very confused. Right now under Phase I there is not even a standard set yet for Indoor Forced Air Wood Furnaces in the U.S., and from talking to a few insiders with knowledge in the area Phase II (tougher standard) EPA certification probably won't be required until 2014. Also it probably won't be an efficiency testing but rather an emissions test, because if your emissions are low your efficiency will be good. We hear it will probably require less than 5 grams of emissions per hour because if it goes any lower than that the majority of companies won't have the means, time, or ability to adhere and be forced to quit manufacturing their furnaces and in turn put them out of business. The Vapor Fire furnace line has been my career project for the past 30 years which includes thousands upon thousands of test burns and many design changes. With endless and I do mean endless work hours we were able to achieve less than 1 gram of emissions per hour which is unheard of.
Here is how we began our certification/testing process. In 2009 the opportunity evolved to offer the tax credit with efficiency certification so we decided to take use Intertek (Who runs 3 of the 7 approved efficiency testing sites in the country) and it's testing facility in Madison, WI. Once we received the great efficiency results we were asked if we would also like to have the emissions tested so we would have the information ahead of time for any changes that we would need to make or potential advertising we would like to do. Being a smaller company with limited means this was not an easy decision to make, because the cost is substantial. However we knew that in order to survive and reach our goal of manufacturing the most efficient indoor wood furnace in the world and a truly green product we needed documented proof. This documented proof is located on our website where a PDF of the test results can be found.
Rest assured that when the opportunity becomes available for Phase II EPA certification we will be first in line. On a side note we have received recent calls from some of our competitors many of which, will have a lot of work to do by 2014, inquiring about the emissions testing process that we underwent.
