Woodburning Furnace - JUCA
Fireplace, Wood Burning Stove - JUCA Super-Fireplaces
and Gas Burning Fireplaces and Stoves
JUCA has produced high quality, high-efficiency, clean-burning wood-
and gas-burning fireplaces, stoves and wood burning furnaces for over
35 years. Over 100,000 Americans live in homes being entirely
heated with JUCA products.
People LOVE them!
Most JUCA units can feed warm air into house warm air ducts to supply
heat to the entire house. The popular Model F-9A (shown here) is rated at
140,000 Btu/hr output (about like a
normal gas house furnace.)
An F-9A can heat the WHOLE HOUSE and looks
EXACTLY like a normal fireplace!
A strong 465-cfm blower
is included as standard, with several options up to 2,550-cfm
(3/4 HP) for VERY large houses. Beautiful Brass Doors are included!
And the F-9A is only about $1,900!
JUCA makes a wide variety of models, including
Built-In Models (F-series),
Free-Standing Models (B-series),
Free-Standing Models with 3 Glass Sides (C-series),
and Fireplace Insert Models (L-series).
JUCA also makes basement-style wood-furnaces
(A-Series) All can use wood OR gas OR both!

Free-Standing Models are available in about
35 standard colors.
The Built-In Fireplace Models can have over
4,000 different appearances! (Including Arch-Tops!)

How Does A JUCA Work???
(Three-glass-sided Model B-3D shown here) Nearly all JUCA models are
individually CUSTOM MADE so a customer can request special features or
special-size dimensions, for a special application or situation.
In addition, JUCA often makes exotic and unusual
units to order, such as a 5-glass-sided unit (for a 5-sided room)
and wedge-shaped units for hyper-modern motifs.
JUCA's efficient operation keeps prices very reasonable
JUCA products all include extremely sophisticated high-efficiency heat-
exchangers. A computer was extensively used in CAD to maximize
performance. That's why JUCAs stand alone in entirely heating
whole houses! Several are GUARANTEED to be able to entirely heat ANY
home in the U.S. This is true whether burning wood OR gas!
With wood, 8-12 hour burn times are normal, while burning cleanly!
That's why JUCA was featured on the
TODAY Show, in
NEWSWEEK,
in the New York Times, in
Mother Earth News
and elsewhere.
JUCAs are entirely manufactured in the U.S.
By the way: It is not NECESSARY to get huge heat output from a JUCA.
On mild days, you can use it to just "take the chill off."
Many owners have found that their house values increased more than the
cost of the JUCA!
(Model B-3B shown here) JUCA products are so advanced that sometimes it
may not be obvious to a prospective customer just all the choices and
options available for a particular house. JUCA
has created hundreds of web-page presentations
to help supply answers to questions
and solutions to unique installation situations. Many background subject
discussions on fireplaces, woodstoves, wood burning, etc.,
are included in its 2,900 screens.
Of course, substantial information is also included on the many
JUCA models, their various options, and a multitude of suggestions
on how best to plan, install and enjoy a JUCA.
All prices of all products are
included, even all the hundreds of options available to you.

E-mail your questions to JUCA at JUCA e-mail
The web-site includes pictures which help one know the distinction
between mantels, lintels and hearths in a regular fireplace;
discussions on modern house-air purity considerations;
hundreds of suggestions on getting maximum performance and enjoyment
from your fireplace/woodstove.
An Inter-Active 'Questionnaire' asks
some questions about the house and then does an approximate heat-loss
analysis of the house. It then suggests the best JUCA and best
blower for that specific house and even calculates the amount of wood
to cut to heat it completely for a whole winter!
Hundreds of other presentations address specific subjects. There's a
chart that describes the burning characteristics of
about 35 species of wood.
A sub-program helps select among over
4,000 different brass-door appearances
available for the Model F-9A! A LOT of useful stuff!
For technical jocks, the web-site includes some really hairy stuff, such
as the
quintuple Integral Calculus equations used to design the JUCA
heat exchangers for maximum performance. Theory, physics, chemistry,
thermodynamics and aerodynamics discussions are included in the
TECHNICAL section.
(NORMAL people don't have to be subjected to
this sort of abuse!)
For NON-Technical people, there are visual mini-movies, charts, graphs
and such to present the JUCA concepts for most people.

The rotating free-standing JUCA Model B-3B at the left shows
a number of its features.
On the front is the large (15" by 21") glass door, and
slide draft control underneath.
On the back is the (Standard) blower near the bottom, the 8"
by 16" warm air outlet (to connect into ducts) near the top, and the
automatic blower control assembly to the right.
Less obvious are the adjustable warm air outlets on the sides, under
the overhangs about halfway up. |
Clean-Burning Non-Airtight Operation |
|
JUCA products are all designed to work on a NON-airtight principle
of operation. This is a VERY important (and unique) characteristic
of all JUCA products. ALL other (competing) woodstoves and efficient
fireplaces operate on an air-suffocation (or air-tight) principle of
operation. That approach NECESSARILY causes major changes in how the
fire burns and how the fireplace/woodstove operates, from how it
would have worked as a "normal" fireplace. These effects
require those products to have designs which have small fireboxes,
small doors and small glass areas, limited heat exchange
areas, and a sealed fire chamber. They also require SERIOUS design
attention to the fact that suffocation designs tend to burn poorly,
and therefore tend to create creosote and pollution.
JUCA uses a totally different approach. Our NON-air-tight design
allows the woodstove/fireplace to operate very similarly to
how a fireplace traditionally operated, VERY cleanly. (You could
even roast marshmallows or make popcorn in it, which you cannot do with
ANY competing product! Competing products cannot be operated with the
door open because the design theory doesn't allow it.) Our
computer-designed heat exchange structure up above captures most
of the heat that would have been lost up the chimney, we have a huge
firebox size, a very large glass viewing area, a large door for feeding
wood, and a blower that is MUCH stronger than any competitor.
All these characteristics combine to capture the most heat possible from
the fire's output, while not messing up the fire's original operation.
That original operation always included very clean burning, which
the JUCA's design maintains. JUCAs do NOT share the air-tight
products' problems of huge creosote and pollution creation. JUCA's
non-air-tight design allows capturing all that heat while burning so
cleanly that no "catalytic combustor" or "secondary
burn" is even necessary or desirable!
This difference between the JUCA's non-airtight design and ALL competing
products (which are ALL airtight) has some other implications.
Because those airtight products developed a bad reputation in the
1980s for creating a lot of pollution and creosote (because of the
suffocation of the airtight operation), the EPA and other government
agencies passed stringent laws applying to them. Commonly, the
chimney must be re-lined ($$$).
A JUCA woodburner does not require all that, and the EPA
and other agencies agree. The JUCA unit actually operates
as a traditional old fireplace did with the only major difference
being that the JUCA captures most of the heat that would have gone
up the chimney. Building fires is the same as in a conventional
fireplace, and the fire behaves as you expect a fireplace fire to behave.
That is definitely NOT true of airtight
woodstoves and fireplaces, which operate VERY differently!
Why are JUCAs different from all competing Woodburners?
The answer to that is pretty complex, and it's why we have hundreds
of informational pages in our web-site. A capsule version:
Back in the 1970s, only Potbelly stoves, Franklin stoves and barrel
stoves existed. They all produced huge amounts of heat, but TOO MUCH,
and for only an hour or two. Great temperature variations in the room
were common. So the problems were: too much heat and too short a
burning period.
Two solutions arose. The Airtight design and the JUCA design.
- The airtight approach was to severely restrict the
amount of air available to the
fire. With less air, less burning (which is actually chemical
oxidation of the fuel) could occur, which means less excessive heat
production, which is good. Since the wood did not get consumed as
rapidly, it lasted longer, giving longer burn times, which is also
good.
With MODERATE restriction of the air supply, this represented a
great improvement over previous woodburners. During the 1970s,
people tended to use them in such an appropriate way.
When energy awareness became dominant about 1980, people started
to try to use such products in extreme ways. They SERIOUSLY
restricted the air supply, to make them operate even more efficiently.
That happened, but an unexpected consequence was extremely poor
burning. Under some conditions, fully 1/3 of the energy in the wood
was going up the chimney as creosote and pollution! Which also
reduced intrinsic efficiency, but no one noticed.
In the early 1980s, a lot of houses burned down, because massive
unseen creosote accumulations in chimneys would catch fire and burn
at over 5000°F, and no chimney could handle that. A lot of pollution
was also getting put in the air.
- The JUCA approach was very different. It involved a
larger firebox, normal non-airtight burning, MUCH thicker pieces
of wood, and a sophisticated heat capture system. In principle,
the fire would be allowed to burn as rapidly as it wished, but
the thick pieces of wood (logs) NATURALLY only burn at a moderate
rate, because burning can only occur at the SURFACE of a piece
of wood. (Thicker logs actually burn more slowly!)
Thicker logs ALSO naturally burn more EVENLY (for reasonably
constant heat output) and for a much longer time.
The JUCA design accomplishes the goals of evenness of heating
and long burn times, in a VERY different way than airtight
designs do. In a far more natural way. The burning is
extremely complete and efficient and clean. Virtually NO
creosote or pollution is created in the fire, as fireplaces
have operated for hundreds of years!
The flaw in the logic so far is that thick logs burn so slowly that
they create rather small amounts of heat. This is why the sophisticated
heat capture and heat exchanger system in a JUCA is so important. It
captures MOST of the heat actually produced, and sends it out
into the room and does not allow it to go up the chimney.
As a footnote, airtight products CAN NOT safely use extensive
heat exchangers to improve their efficiency. Since they naturally
produce so much creosote in their smoke, and creosote condenses
out at about 350°F, they must NOT be extremely efficient. Otherwise,
they would cause massive creosote accumulation in their chimney
systems. Some products like that were briefly sold around 1980,
but they proved to be very dangerous products for this reason.
Since JUCAs are non-airtight, the fire burns very cleanly, so
there's little very creosote in the smoke, so we can capture
the daylights out of the heat in the smoke! An optimally
efficient JUCA can have smoke temperatures of 250°F. We are thus able
to capture more than an extra hundred degrees of heat from the
smoke before it goes up the chimney! Voile! Very high efficiency!

JUCA Built-In Fireplace Models
Other companies' 'Zero-clearance' fireplaces all have unusual appearance,
which give away the fact that they are not actually massive masonry
fireplaces. Not so with the JUCA F-9A series. The JUCA facing
appearance is exactly like a conventional fireplace with a set of brass
doors on it. There are no ugly black metal panels with air holes
around the door opening. (All the "performance parts" are
hidden inside the wall). 'Brass' may be too specific a term
here since JUCA offers Antique Brass, Polished Brass, Satin Brass, Black,
Copper, Chrome, Pewter, Nickel, Swedish Metal, Enamel, and all manner of
combinations of these. Most mantel treatments are compatible with a
JUCA F-9A. In recent years, Arch-Top JUCA F-9As have become
quite popular. Over-size dimensions (or dimensions to
suit a specific space) and many custom options are commonly included
as part of an F-9A. JUCA offers over
4,000 different "standard"
appearances! If this incredible choice isn't enough, even
gold-plated and platinum-plated optional facings
have occasionally been requested and supplied!
The F-9A is rated at 140,000 Btu/hr output, WAY more than any competing
fireplace. All JUCAs use conventional large or small house ducting and
normal warm air grille outlets to get the heat out into the room (and
house). The air intakes and outlets DO NOT have to detract from the
appearance of the fireplace. They can be on other walls or
even in other rooms!
No matter WHAT decor and "mood" you want to create, a JUCA
F-9A can help achieve it.
Performance to heat the ENTIRE HOME combined with beautiful
conventional fireplace appearance and operation. Wow!

Built-In Traditional Fireplaces
Most people tend to select a conventional rectangular fireplace
appearance on their JUCA Fireplace. The standard size of the F-9A
is the so-called 36(w) by 28(h), the most popular size fireplace in
the U.S., but JUCA has made units as wide as 78 inches! About
1,300 different "standard" appearances are available in
rectangular shape, to fit in with ANY room decor. This
includes a variety of finishes, frame widths, and door appearances
and opening modes.
All this at VERY REASONABLE prices and relatively quickly.

Some applications need a through-the-wall fireplace for aesthetics reasons.
The JUCA F-9AX model handles these situations. Even for unusual situations
when one side needs to be an Arch-Top fireplace and the other side needs to
be conventional rectangular, the F-9AX is the unit to get. Competing
double-sided fireplaces require identical appearance (usually with black
metal areas) on both sides. The JUCA F-9AX could have Polished brass
Traditional Bi-Fold doors on one side in a Great Room (for a regal
feeling); and Black Clear-View Twin doors on the Family Room side
(for a cozy feeling). And, as always with a JUCA, the unit has
ability to heat the whole house!

JUCA Gas-Burning Units
All of the normal JUCA units are built very sturdy, in order to be
able to burn wood safely. However, all can be combined with a normal
gas-log set to make it a gas-burning unit, too! In this way, double
benefit is gained. If the user feels industrious, the gas logs are
removed and wood is burned; at other times, the gas logs are burned.
In both cases, the romance of the fire is present, as well as the
JUCA performance to heat the whole house! The changeover usually
only takes a couple of minutes.
JUCA's gas-burning units can have manual control, wall control,
remote control, or even wall-thermostat control. This last
choice can allow the JUCA unit to act as the automatic central
heating source for the house!
The gas-burning capability of a JUCA can be delayed until later. The
unit can be used as wood-only for now, and then later gas can be used. As
long as the unit is built with the gas-line stub pipe installed, the
gas log-set could be installed years later, using wood now!
Great flexibility!
The opposite approach can also be used. As long as gas is reasonably
priced (AND AVAILABLE), why not burn gas in the fireplace, heating the
entire home in the process? If something silly happens again in the
Mid-East (and it will), where conventional fuel sources are interrupted,
then take the two minutes to remove the log set and start burning wood.
The best of both worlds!
See any of the JUCA models listed above. All can be wood-, gas-, or both.

high performance in a Solar Heating system, you might want to visit
the Solar Heated House NorthWarm Totally Solar Heated House - Version 1 web
site. Most of the Solar systems are based on a patented system.
Even better, the Version 1 System includes a sub-system that
is also a way of entirely Air Conditioning virtually any existing
house in the United States nearly for FREE! In a spirit
of hoping to assist California homeowners (2000) from enormous summer
electric bills (and power outages), this sub-system is being made
available, for FREE, at Home Air Conditioning
We hope that, if enough California homeowners
would install the simple system, maybe the power companies and the
energy grid could keep up with the Summer high demand for electricity.
Since we're giving this information away, you could probably help
some of those California homeowners to tremendously reduce their summer
electric bills and maybe help avert blackouts out there, so let any of your
California friends know about that possibility available to them!
We are also involved with a variety of other projects that are meant to
give benefit to society in one way or another. Some are social or
intellectual presentations, meant to help find solutions to things in
our lives. Others are products or services that also are meant to
somehow improve our lives. If you have curiosity about this,
you might want to visit a directory page we set up for these
Public Services Home Page.
If you are civic-minded or otherwise motivated, a number of those
