Biomass Heating and Cooling
BIOMASS CHEAPER THAN FOSSIL FUEL- Download
Dec 1. 2005 Press release PDF
Natural gas is $15.00 per mmbtus. Propane costs $20.00 per mmbtus. Electric heating costs
$30.00 per mmbtu. Conventional firewood at $100 per cord delivers heat at under
$10.00 per mmbtu when burned efficiently (84%). If you have access to wood, consider
being a Heating Entrepreneur in your rural community. The average rural school
spends over $150,000 a year on propane, why not spend that money for firewood
produced by the local community? A Coop for rural Heating Entrepreneurs is
being studied, see www.heat.coop
Althouse is the exclusive New Mexico dealer for Garn boilers. High efficiency
combustion of a variety of low cost fuels with integrated thermal storage
for 24 hour a day comfort. Go to the Garn website http://www.dectra.net/garn/Wood_heat.htm

*Btu/hr storage is extremely fuel dependent. These numbers based on
the use of split, 16" oak with 20% moisture and a reloading once an
hour.

Why does a GARN® WHS unit perform so
well?
Combution air is drawn directly from
outdoors through an internal air inlet tube (A) to the air
distribution collar (B). The door (C) prevents air from
being drawn from the room. The door is insulated to prevent heat loss and
includes an air-cooled heat shield to prevent hot surfaces near the user.
Combustion air from the collar flows through an upper and lower nozzles (D)
into the combustion chamber (E). Remaining free air is mixed with
hot gases before entering the ceramic secondary combustion chamber (F).
Within the ceramic chamber, smoke, creosote and particulates are burned at
temperatures near and above 2000 ºF. The hot gases release their heat as
they move through a 5 pass tubular heat exchanger (G) submerged
within a large volume of water. The cooled gases are then pulled into the
Draft Inducer housing (H) and pushed out of the exhaust pipe (I).

Adsorption Cooling
Althouse is the New Mexico source for adsorption cooling systems that use the
Garn boiler in the summer to provide chilled water for air conditioning.
Eliminate high air conditioning electric bills and the accompanying high on peak
demand charges. Visit http://www.adsorptionchiller.bigstep.com/
for more information about our air conditioning systems.
 | Water used as refrigerant, no freons, no Li-Br, no ammonia means : No
hazardous leaks, no corrosion, no chemical testing, no replacement.
| No compressor means: No alignment, no high voltage, no high pressure, no
overhaul, no oil change, no surging, no vibration or noise.
| Stable chilled water out-put driven by a wide range (194 to 122oF) of hot
water.
| Capacity out-put remains stable as in-put fluctuates. No back up burner
required
| Simple and short start up / stop time
| 38 F of chilled water is in the standard specification.
| Constant operation - 24 hours / 7 days a week. |
