JUCA 3-Glass-Sided Wood/Gas Fireplace Furnaces

pix of an B-3D Efficient and majestic, the B-3D will blend in with any decor. The combination of the modern tapered shape over large glass areas and the massiveness of personally planned stonework or brickwork surrounding the lower part, makes an impressive statement in the home. The versatility of being able to install it upstairs or downstairs; of using it as a room heater, as an add-on furnace, or as a separate furnace; of being able to enjoy the fire from everywhere through three large glass panels; make it the best product on the market. Since it has the capability of heating even very large houses (since it has a large duct connection outlet to be able to feed warm air into the house's central heating duct system), and since the firebox is large enough to take giant pieces of wood, you get long, even, constant heating just like with a regular furnace. You just don't have to pay for the gas, oil, or electricity! JUCA even GUARANTEES that the B-3D can fully heat ANY single-family house in the U.S.A! (After all, the B-3D has a rated output of 180,000 Btu/hr, more than most house central furnaces) (But it can be used at very low heat outputs,too!) All this, at the amazingly low price of around $2,400!

Gas Burning

When the JUCA B-3D is used with a 24" set of gas logs, the appearance is exactly that while using wood. The enjoyment of watching the flickering fire through the glass walls is wonderful. While this is happening, the 90,000 Btu/hr gos-log burner (and the JUCA, of course!) is creating enough heat to be heating the whole house! A variety of log styles are even available, from Mountain Oak to Twisted Cypress to White Birch. Various accessory control systems can use a wall thermostat to cycle the burner on and off like a gas furnace or be controlled by a handheld remote control. The automatic operation of the fire cycling on and off is a popular option so that the JUCA fireplace acts as the house's central heating system.

It's great to have this mode of operation while gas prices are reasonable while STILL having the capability of heating the whole house with wood if something silly happens again in the Mideast. The change only takes a minute or two. The best of both worlds!

JUCA Model B-3N, showing features
The rotating JUCA Model B-3N at left shows some of its features.

On the front is the large door that is nearly all glass , with the slide draft control underneath.

On the sides are more large glass areas to view the fire. Less obvious are the adjustable warm air outlets on the sides, under the overhangs, above the glass areas.

On the back is the (Standard) blower near the bottom, the 8" by 16" warm air outlet (to be able to connect into ducts) near the top, and the automatic blower control assembly to the right.

A slide draft control under the door can adjust the fire. Dozens of optional colors are available for the top half to liven up a room; however matte black is standard. Our standard blower is nice and powerful and is automatically controlled by a built in temperature probe. The optional blowers are even stronger (up to 3/4 hp), and one of them is usually necessary when feeding central heating ducts to heat a whole house. Adjustable air outlets on both sides also send warm air out into the room, down along the floor where it does the most good. Our glass door and glass side panels use high temperature glass, but we also include removeable metal inner safety panels that slide into place when the unit is unattended (while you're at work or asleep) to make sure large logs can't shift and crash into the glass. We believe that JUCAs are the only glass-doored wood burners with this extra safety feature. Blower is 115 volt, and most are energy efficient.

Whereever a JUCA is installed, you get remarkably even, comfortable, long-lasting heat everywhere in your room and house. You can completely eliminate your regular heating fuel bill. It feels great to carry wood to your JUCA when you know that each armload saves you about $3.00 (or more) on your heating bill. There are no cold drafts, even at floor level. The built-in computer-assisted-design heat exchanger is so efficient that you get more usable heat with less wood burned.

Model B-3D

The elegant B-3D fireplace can be the dominant centerpiece of any family room or great room. This model is our most popular Three-sided-glass model. Guests are ALWAYS amazed that it is also heating the whole house!

The B-3D has similar performance (actually even better) than our work horse B-3B, combined with the breathtaking appearance of having glass on three sides for viewing the fire from everywhere in the room. A true conversation starter for a conversation pit!

This beautiful free-standing unit has provision to be able to feed warm air into the house warm air ducts, just like nearly all other JUCA models.

Sometimes, owners arrange for the B-3D to be installed as a "peninsula". This provides for a very simple way of hiding the blower and the duct connection on the back of it. Sometimes, owners arrange instead to have removable "privacy screens" between the B-3D and the rear wall for the same function.

Model B-3C

An installed B-3C looks identical to a B-3D. This model does NOT include the lower half of the firepit as part of the unit, which includes the firebrick lining of the firebox and several heat baffles and air spaces beneath the firebox floor. (This used to be a very popular approach, and a few contractors still like this type unit because it allows them the flexibility to make more unique masonry lower portions of the final installation. ) In other words, the Model B-3C has an open bottom!

A B-3D has all that heat baffle and multiple air chamber stuff under the firebox so that it can be installed over a wooden sub-floor, where the B-3C Model does not include this - since it has no bottom, it MUST be installed on a totally fireproof masonry base/firepit.

Models D-7 and D-3

These are different height versions of the B-3D (shorter and taller). JUCA performance is so great, that the amazingly high ability of the D-3 is pretty much irrelevant for any realistic house. These models should be chosen for aesthetic, height considerations.

Models C-7 and C-3

These are different height versions of the B-3C (again shorter and taller), again without a bottom. (See the description in the B-3C description above).

Models B-3N and B-3JN

These are smaller versions of the three-sided- glass B-3D, for locations with limited space but where you still want to see the fire from all sides.

Special Custom Free-Standing Fireplaces. JUCA has also made many specialized units for specific applications. Four-sided-glass units allow looking clear through it! Six-glass-sided and 8-glass-sided units have been made; even an asymmetric 5-sided glass unit was built to match an unusual room. Normally C and D units are free-standing, but there are ways to install them to make them appear built-in as peninsulas or islands.

Any of these units is available in any of dozens of colors with any of our 6 blowers and/or other custom features, at reasonable prices and is usually shipped in a few weeks! WOW!!
