Stainless Steel better!
offer both options Stainless or
Mild Steel. Well you hear a lot of good points
from both sides. I personally purchased the mild steel
unit. The warranties are usually about the same and I
simply look at it this way. If my mild steel unit
lasts 20 to 25 years the unit paid
for it self over 10 times. Stainless Steel is
also made from different metals which shrink and
expand differently causing hairline fractures. For
the additional cost of about $1400 I personally
don't see the value. Also ask a welder "what welds
Better mild steel or stainless steel?" Mild steel
Dual Fuel Important?
outdoor wood furnace is designed to be incorporated
with an existing indoor heating system such as a hot
water boiler, radiant heat, domestic hot water and
forced air furnace. If your wood furnace is hooked up
correctly, your existing indoor furnace will act as
your back up to your wood furnace. Don't worry, your
indoor furnace will also prevent the wood furnace
from freezing while you are on vacation. We
recommend a indoor furnace for a couple simple
reasons 1. for resell reasons and most
home owners insurances require it. 2. wood furnaces
are designed to burn a solid (Wood) fuel they are
very very inefficient burning a liquid (Oil) fuel.
Need More Info: Now with that in mind
read the next paragraph.
of purchasing a outdoor wood furnace with the optional
of dual fuel hook-up is an additional cost. Keep in mind,
furnace is a permanent structure which is now taxable
and needs permits. I thought the purpose of a wood
furnace was not having to pay bills.
to conclude this topic it simply doesn't make any
far away can it be?
Outdoor wood furnace has the ability of being 3 to 300
feet away from your home. Couple things to keep in
mind. You will need to visit your wood furnace once a
day. You will need to have easy access to this
location truck or tractor to replenish the wood when
much wood will I use?
that depends on your home, insulation and the quality
of wood you're burning. This might help! 2,500 sq home
well insulated with good wood will go through 5 to 7
cords a cold session (6 months) That is heating the
home and a domestic hot water 60 gallon tank.
The cost of a cord these days is
$120. You can see the savings if you buy. That is
$600 to $840 a year to heat your home naturally.
What did you spend last year? Imagine if you get
I go away for a couple days?
is one of the most common questions that I get. You
have several options depending on your
If your wood furnace is hooked up correctly your
existing indoor furnace will back heat the wood
furnace preventing it from freezing! The cost of
your indoor furnace back heating your outdoor is
very minimum cost everything is very well insulated.
Couple more options for you!
First you can let the fire die down and drain
the furnace. This is what I do it only takes about 10
minutes to drain the unit. When I return I refill the
unit and relight the fire.
Second you can set up your unit with a
bypass to not heat the home and circulate within
itself the burn time will be much much longer 4
to 5 days.
Thirdly if the weather isn't really
cold the circulation pump is moving the water
quite quickly. Moving water is hard to freeze.
Fourth Maybe a friend or family member
could help and feed the unit while your away.
Fifth You could look into anti freeze.
Keep in mind most anti freeze is terrible to our environment.
please dispose of properly!
Sixth "If there is a will there is
if the electricity goes out?
is another commonly asked question. The outdoor wood
furnace uses very little electricity which can be
supported by a small generator. What I actually did is
I ran a regular inexpensive extension cord to my unit
and that is how my unit is wired. So all I need to do
is unplug from the wall and plug into a small
generator. Problem solved. Some people ask well if you
don't have generator you have no heat. That is
correct! Most homes loose electricity they have no
heat either. Either way you will need something to
back up your existing home as well as the wood furnace. I
know several people including myself are looking into
solar and wind options. These wood furnaces use very
little electricity. As soon as I get off the grid I
will let you know.
long will a wood furnace last?
this is like asking how long will my car will last.
The simple truth is that we have a 10 year warranty.
which has excellent coverage. These units should last
20 to 25 years or more if they are used and maintained
properly. The oldest outdoor wood furnace I have seen
is 14 years old with no visual wear on it and running
strong. Wood Master wood furnaces should last longer
than most units simple because they have superior
construction and more importantly a superior design.
Design is the most important issue here. If you ask a
plumber they will tell you that what kills boilers
(Outdoor wood furnace is basically a boiler) is
sediment build-up which rots the boiler inside out.
With our design we use a round drum where sediment can
not build up and we have a drain at the bottom to
flush the unit out yearly. Some units have a square
water chamber, "water baffels", zig zag tops
to help heat tranfer which will catch all the
sediment. These units have no way to
flush the system as well. They try to solve the
problem with chemicals and in line filters which you
can add to your bill. I know this because I have owned a
one since 2002. I still own it and I had to move it
over to the warehouse in which I store my wood
master parts and supplies. I can no longer run it in
my home because of a neighbor who lives 700 feet away
complaining about the smoke.
Sorry No More Pictures!
AS per request of the competition, I can't
show any pictures of the competition. They asked me
to remove my pictures or they would take legal
action! Truth hurts!
Makes Wood Master better?
is like a young person that joins a company that
raises all these ideas how to do everything better way
than the way you have been doing it for years.
Simple; there is a good reason why it has been done
this way for years. What I'm getting to is that this
is what has been done with a couple other wood furnace
companies. I will describe them below for you and you
make your decision which make more sense.
The zig zag feature which helps heat more water; good
idea except that is where all the sediment will build up and
start to rot the furnace out from the inside and not
to forget the additional welding (as
discussed in How long will a wood furnace last)
There is no way to clean the inside of these units.
If you look at the door location and the Heat
Collection area This air is 1500 degrees; another
good idea until you have to open the door. The heat
baffle is lower than top of the door. That is
where you are standing and when you have to put a big
log in and you are displacing several cubic feet of
1500 degree air; where is that going? You got it in your
face. I have lost many eye brows and facial hair, and had to
listen to my wife laughing at me. I know first hand I
owned one for several years and still show mine
customers. (side by side comparison)
Natural draft is a bad idea:
These units are known to smoke a lot due to their
natural draft. To give you an idea it is like throwing
a match onto a leaf pile, how much will it smoke? Your
right a lot! Now if you do the same thing and then
blow on it, what happens then? The fire starts and
gets hot faster and a considerably less smoke. As you
can see this is not rocket science, these ideas were
good ideas but not practical, similar to that young
kid on the job tell the experience guy better ways of
With a Wood Master we use a round drum which will not
collect sediment and can be easily flushed to prevent
rotting from the inside out.
We use a fan on the front of our unit to burn hotter
to reduce smoke and higher efficiency.
With using a round drum you have 50% less welds.
We have smoke release area so you are not eating smoke or
hot 1500 degree air while filling unit with wood. This
is a eye brow saver!!!
Did I mention we cost about $1,800 less then the equal
size competitive unit. Heads up the will say their
smaller is equal to ours to try to prices closer.
The truth is very easy to figure out. How many cubic
feet in fire barrel will tell you which goes with
which. Don't listen to BTU ratings! This is very
dumb statement, what kind of wood are you burning?
Green, seasoned, wet, rotten, Oak. Pine, way to many
variables to mention. Fossil fuels can do this
because there is a constant fuel source. Example Oil
burns at about 2000 degrees and propane around 1400
degrees we can give a btu rating with this NOT WOOD!
Our wood furnaces are on legs and don't use a full
skirt for a couple reasons. First if it is warm
and dry rodents will find a new home in all that great
polyurethane insulation which is excellent to dig in
and hard to fix! Again this is experience talking.
(Field mice had babies, they are so cute! But
not in my furnace) Secondly with the full skirt
they suggest a concrete slab. This now makes your
furnace a permanent structure in most towns and you
will need permits and it is now taxable!!! I love
Did I mention that our furnace is $1800 less!
Final Note! Very Important!
Ask to read their 25 year Warranty!! You might feel
like a deer in headlights! Basically I will sum it
up for you quickly. There is a 10 year prorated
warranty on the fire barrel and only 1 year on the
electronics. (My Control panel blew at a cost of
$166.00 after 2 years). ARE YOU READY FOR THIS? The
25 year warranty is on Manufactures defects! If some
knows what this covers please let me know. (Blemish
in the paint or what?) Just another game. I learned
this the hard way and all I want to do is recommend
all the other brands before this one. Please don't
make a Classic Mistake like me!!!!
Can you put antifreeze in your unit?
you can however it might get pricey. There are a
couple alternatives that might help you with this
If you're going away just empty your unit and lines; this
is very simple. Refill and restart your fire it takes
about 4 to 6 hours to get back up to temperature.
If you have a boiler in your house and using a
plate exchanger to heat your boiler this will also
back-heat. What that means if your unit temperature
drops your, existing boiler will kick on to provide
heat to your home, it will also will heat the water in
the boiler and prevent freeze up. Yes you will be
using more fuel to heat your home and the outside wood
You can also set up a by-pass. What I mean here is you
setup a by bass from the outdoor furnace from heat the
house and send the water right back to the unit. So
the unit is only heating itself which will last for
days maybe week or weeks depending on temperature and
Where do you get wood?
phrasing it like this: were can't you get wood! Wood
can be found easily. For example tree companies have
to pay to dump wood in landfills and other locations.
They most likely drop off the better hard woods; but we
don't care we can burn all wood. Most tree guys can't
sell certain types of wood (soft wood like pine,
hemlock) so the have pay to get rid of it or drop it
off to you free of charge. Once you build a relationship
with a couple tree guys you will be home free.
look around it is all over the place. Free Pallets all
over the place. I never heard a neighbor say no to
allowing you to going in cleaning up downed trees and
branches on their property.
can also call tree companies a ask them to cut the
wood at 26 inch lengths and don't have to split it-what will the cost be?
Also mention to them to bring
the wood they can't sell to other customers such as
V's of the tree, Big Knots, and all those weird shaped
pieces. They should deliver it to you with a smile at
half the cost. In CT it should cost about $150 to $175
a cord delivered, You should get it for $75 a cord delivered.
Can you burn coal?
we don't suggest it. The whole reason for buying an
outdoor wood furnace is not to buy a fossil fuel and
or burn fossil fuel. Your home already has the
capability of burning fossil fuel.
