Shaver Outdoor-Outside Wood Burning
Furnace-Stove- Boiler is the BEST
______________
First and foremost
the firebox thickness is the most important factor. We
have the thickest firebox available in the industry at just shy
of 1/2" - compared to 1/4" from our nearest competitor.
That's 100% thicker and that's important because the firebox is
always the first thing to fail. Most furnaces are only .125 to
.1875" thick, with only 2 others that are .250" thick.
We have a 20 year parts AND labor ON-SITE warranty. Most
others just cover parts or their warranty is much shorter -
read the fine print!!
There is a forced-air blower in back that feeds air into
the firebox, below the grate, to feed oxygen to the fire.
Feeding the fire from the bottom (just like a blacksmith would)
is the best way to get complete combustion from the wood. This
is infinitely better than a fan on the front door blowing air
into the side of the fire - or a manual draft. The fan is
thermostatically controlled to keep the water at a set
temperature and is adjustable.
The grates are made out of 3/4 inch bar stock. We have
NEVER had one burn through!
The ash "pan" (non-removable) is approx. 16" wide x 34"
long and is 8" high (on the 165 model and up to 68" long on the
340 and TW4000). Many furnaces don't even have one, requiring
you to let the fire die down in order to clean it.
We also have a 50 foot POTABLE water coil (for your water
heater) made out of 50 feet of coiled 5/8" OD copper tubing!
With our built-in heat exchanger don't need a separate heat
exchanger for the hot water heater, often called a side-arm
exchanger. We have 3 water outputs standard. One is potable
water using a sealed copper coil and lines to your water heater.
The other outputs give you the whole 170 - 300 gallon tank of
water that is circulated with a pump to the inside heat
exchanger.
We have a 170-300 gallon water tank! Many manufacturers
only use 90-125 gallon tanks! The size is critical when heating
a larger home. DON'T BELIEVE IT when they say they can heat
4,000 sq. ft. and have 300,000 BTU from 100 gallons. That's
impossible without heating the water to over 300 degrees!
Science is science!
The firebox is round and infinitely stronger than any
square firebox will ever be! On the 165 model, it is 36" wide x
26" high (due to the grate and ash pan in the bottom) x 34"
deep. The 340 model is 68" deep! It is made from almost 4/10th
of an inch of solid steel. We've never had one rust through or
crack!
It is totally surrounded with 170 -300 gallons of water,
so that it absorbs the maximum amount of heat possible! The
water jacket surrounding the firebox is rectangular and is made
from 1/8 inch thick metal - the standard in the industry for
water tanks - as opposed to auto body thickness sheet metal on
others. We are two times thicker; 11 gauge vs. 16 gauge.
The chimney is made out of 5 inch schedule 40 pipe (1/4"
thick) and is surrounded by water as well. It tops out at about
90" above ground. You can EASILY add extensions with standard 6"
stovepipe.
The chimney is low in the firebox and exits about 1 foot from
the bottom shelf, so that the smoke - or more importantly,
the heat - is trapped so that it doesn't quickly escape out
the flue. That would be a big loss of efficiency. This is also a
better idea since you don't have baffles creating a lot of smoke
and getting a creosote buildup on them that's hard to clean.
This also creates a 2nd burn chamber, to more completely
burn the gases and wood! When wood starts to burn it's the
escaping gas that burns first, then the wood! This is a type of
gasification furnace but we do it a whole lot simpler and
without any computer parts or circuit boards.
The water surrounds the ash pan as well. As anyone with a
wood-stove or furnace knows, ashes put out a lot of heat!
There is a full-size rear door approx 40 x 48 inches.
This makes it VERY easy to make connections and to service it.
There is no need to pull the whole shell off as with other
furnaces!
We have an extra large, waist-high loading door - 18" x
18" suitable for putting BIG pieces of wood in! A 30"
piece, only 15" in diameter will weigh 115 lb!
The door material is made with a 1/2 inch frame and a 1/4 inch
outside steel plate plus a 1/4 inch thick inside steel plate
separated by the air gap between the steel plates. This door
will never burn through! The insulating ability is the air gap
plus the reflective factor of the inside plate. The inside plate
only 4 bolts attach it to the door so there is very
little heat transfer. There is also insulation between the
plates now!
These furnaces now come with an automatic double flood light
on the front for safety and ease of loading the wood. Not only
that, it's a MOTION LIGHT! No switches. No forgetting to
turn it off. If it's dark outside and you go near the furnace,
it turns on!
There are legs on the bottom with a
skirt surrounding the bottom to ground level to keep it warm and
dry.
The exterior is made of Heavy Duty Siding - 29 gauge with
10 coatings and it has a Lifetime film integrity warranty and
30 years against fade and chalk
We can build just about anything. Billy did one recently
with FIVE outlets!
Remember, the
20 year parts AND labor ON-SITE warranty - even in Canada -
is probably the best feature because at least 50% of the
manufacturers out there require that you ship the furnace back
to the factory to get it repaired. Then they have to ship it
back and while the repair may be free, they charge you for
the shipping both ways AND you have to disconnect the
furnace, reinstall it and be without it for 2-4 weeks.
