Indoor Biomass Boiler | Furnace
That being said, there are other manufacturers of quality "biomass" indoor boilers and
furnaces that sell for far less money.
One is the A-Maize-Ing Heat Furnace line from LDJ Manufacturing. The A-Maize-Ing
product line consists of a forced hot air furnace that works with your home's existing
ductwork, and a boiler system for radiators, baseboards, or radiant floor heating. Both
systems burn corn or wood pellets.
There is some confusion about who actually produces the A-Maize-Ing Heat brand.
The A-Maize-Ing Heat brand name is owned by several manufacturers who purchased
rights to produce the bottom fed biomass burning system. The forced hot air furnace
and boiler described in this article are from LDJ Manufacturing.
The boiler and furnace are each available in two sizes: standard 100,000 Btu or
165,000 variable rate. Variable rate means you can adjust the heat input level up or
down to suit your needs. The LDJ variable rate units have a range extending from
80,000 to 165,000 Btu's. The units will still cycle on and off depending on your
thermostat (furnace) or aquastat (boiler) setting.
Also, when you see Btu ratings for stoves and furnaces they're talking about heat
input. What you get out of the other end as heat depends on the efficiency of the
appliance.

For instance, an old 100,000 Btu furnace that is
only 70% efficient will produce 70,000 Btu's of
useable heat - not 100,000. According to the
A-Maize-Ing spec sheet, the furnace and boiler are
rated at 85% efficiency.
The LDJ forced hot air furnace with 14 bushel
hopper is a stand alone system that can be used
for new construction or to replace your existing
furnace.
It can also be used as an add-on furnace and
ducted in parallel with your existing system by
utilizing a back draft damper. Both the standard
and variable rate furnaces are factory ready to add
air conditioning.

In a closed loop system, the internal water is continually
re-circulated instead of exchanged for fresh water. This
lessens the potential for expensive repairs caused by
rust and corrosion.
The boiler tank holds 18 gallons of water and maintains
an operating temperature between 160 and 180
degrees. If you're plumbing into an in floor system, you'll
need a mixing valve to bring the water temperature
down to the recommended level.
The LDJ boiler also functions as an add-on unit or can be
fitted with a water to air heat exchanger to replace the
burner in a forced hot air system. A domestic hot water
coil is available as an option.

If you've visited this page
before you can't help but
notice the Aqua-Therm indoor
biomass boiler is no longer
featured.
The reason I featured it in the
first place was its ability to
burn wheat, rye, oats, etc., in
addition to wood pellets and
corn - something other
biomass boilers and furnaces
aren't capable of.
Unfortunately, I was recently
told by a dealer that the Aqua
Therm by Verner would no
longer be available in the U.S.
