Corn is
a fuel that is widely available in many parts of
the country and can be used in the Multi-Heat boiler.
Corn can be purchased in bulk or by the bushel (56
lb bags).
The energy of content of corn is
not constant, but approximately 20 lbs of corn is
equal to a gallon of fuel oil. On average, the energy
content of corn is between 8,000 to 8,500 Btu/lb
of dry matter. One Btu (British Thermal Unit) is
the amount of energy needed to heat one pound of
water one degree Fahrenheit. To get the net dry
Btu rating on corn one needs to factor in the moisture
content. Average moisture content for corn is 12-15%.
This gives corn an average BTU rating of 6,800 Btu/lb.

| Wood Pellet Fuel
is a biomass fuel manufactured from ground wood, waste
wood, bark, and other combustibles which is pressed
through dies at very high pressure.
Wood Pellets can be purchased in bulk or in 20
or 40lb bags. The energy content of pellets is more
constant than corn because of lower moisture content
(4 -8%).As a rough approximation, 17.5lbs of wood
pellets provide the same amount of heat as a gallon
of heating oil. With these characteristics, wood
pellets burn very efficiency. They are also very
easy and safe to transport and store. Wood pellets
have an average net Btu rating of 8,200 Btu/lb.
