Most JUCA units can feed warm air into house warm air ducts to supply heat to the entire house. The popular Model B-3D (shown here) is rated at 180,000 Btu/hr output (like a normal gas house furnace.) A B-3D can heat the WHOLE HOUSE and looks BEAUTIFUL! A strong 465-cfm blower is included as standard, with several options up to 2,550-cfm (3/4 HP) for VERY large houses. Available 35 standard colors! And the popular B-3B is only about $1,900!
JUCA makes a wide variety of models, including Built-In Models High-Efficiency Fireplace - JUCA Super-Fireplaces, 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 JUCA Central Wood-Burning Furnaces All can use wood OR gas OR both!
Free-Standing Models are available in about 35 standard colors.
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-3D 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.

FREE Air Conditioning??
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.
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 Woodstoves?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.

Unique Free-Standing Fireplace-Woodstoves
In case one of the many JUCA 'standard' custom-built fireplace/woodstoves
doesn't fit your needs, JUCA can certainly still fulfill your needs.
JUCA has made units that included 'bread ovens,' internal cooking
provisions, 4-Glass-Sided and 5-Glass-Sided units and many
other unique units for specific applications.
In case one of our 35 standard colors. doesn't ring your chimes, we have the capability of other possibilities. Shoot, we've been wondering when someone would order a polka-dot unit!
Other Unique JUCAs for Specific Applications
JUCA loves to create unique custom-designed fireplaces, woodstoves,
and wood burning furnaces for specific situations. Many very
unusual appearing JUCAs now heat homes. In addition, JUCAs heat
greenhouses, warehouses, factories, pig brooders, barns, garages,
pole barns, etc., etc.
Considering what JUCA calls 'standard,' these are usually 'cake!'
All this at VERY REASONABLE prices and relatively quickly.
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.
Roughly $1,900 (depending on model)

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 from enormous summer electric bills (and power outages), this sub-system is being made available, for FREE, at 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.
