1 LHV- the heat value of a combustion process assuming all the water component is in vapor state at the end of combustion, so that its 

latent heat is not available.

2 HHV- the heat value of a combustion process assuming all the water component is in liquid form of the combustion gas, the HHV 

takes into account the latent heat of vaporization of water in the combustion products.

G. Please provide a list of characteristics that are critical for pellet fuels used in the units you manufacture (e.g., moisture content, ash 

content, dimensions, etc.) and why you think so.

Ash Content, Moisture Content, Fines, Species of Wood, and Overall dimensions are all important to the operation of our pellet units. 

Variability of these characteristics has no doubt been the biggest challenge to our end users (and therefore the manufacturers) over 

the last several years. When the customer becomes accustomed to the performance, heat output and maintenance intervals required 

by a specific fuel...and then those qualities change, the customer is forced to modify or alter how they use and maintain their

appliance. This isn’t necessarily the issue between “West Coast” and “East Coast” fuel which we’ve dealt with for years, but 

variability of quality and consistency within regions and sometimes within brands which makes it difficult to keep up with. We’ve done 

all we can do to educate our customers on visual cues which might suggest they need to alter the operation of the units or increase 

the maintenance intervals but more consistency and control of the composition and performance of the fuel would:

 greatly increase the satisfaction of our customers

 greatly reduce warranty/customer service cost for manufacturers

 result in finer tuned, cleaner burning more efficient appliances

 Reduce the R&D costs of developing new units
