IDEAL STEEL Hybrid

I. AFFORDABILITY

1. Affordable price (<$2,000) has been achieved by

relying on (1) steel fabrication, (2) simplicity of design,

and (3) no electronic controls,sensors or power.

2. Design Book - Affordable Aesthetic Choices

We achieve varied and creative designs by welcoming

the creativity of our customers. Once a customer initiated design has been completed, it goes into our Design

Book and is available either free, or at a nominal charge. 

II. EFFICIENCY

1. Record 82% Efficiency during EPA Testing, using

CSA B.415.1 Tested by Polytests Services, an independent lab certified by EPA in Napierville, Quebec.

2. Over 80% Efficiency with Cordwood Testing

performed according to the September 24, 2013 draft of

ANSI Standard for Cordwood Testing

3. Simplicity of Combustion Design. Durability

and longevity depend on simplicity. Our results are

achieved with a simple hybrid firebox design, and (a) no

energy inputs, (b) very few moving parts, and (c)

rugged, durable construction.

III. EMISSIONS

1. 0.54 g/hr emissions using method 5G3

2. “Adjusted” emissions of 1.04 g/hr.

3. Lowest “high burn” emissions on record. Normally the way to lower the “weighted average” emissions is to limit the high burn rate to under 40,000

BTU/hr. The IDEAL STEEL Hybrid emits a record low

1.3 g/hr at 60,000 BTU/hr.

4. Totally reproducible emissions results using cribs

or cordwood, and from one lab to another.

IV. INNOVATION FIRSTS

1. First Affordably Priced High

Performance/Low Emissions Stove

2. First Hybrid Combustion System that delivers

very low emissions across a wide spectrum of outputs

including high burn rates up to 60,000 BTU/hr or more. 

3. First hybrid stove with automatic control of

catalyst air, to assure high efficiency and low emissions at high outputs.

4. First stove with easily customizable sides, top

and andirons, so that an owner can participate in the

design of his/her stove.

5. First stove to use a radiator to distribute catalyst

heat.

6. First stove with adjustable leg height (so it can

be installed in front of a fireplace with a low lintel)

7. First stove with a multi-temperature cooktop

engineered to capture heat from catalyst.

The IDEAL STEEL Hybrid was developed by Woodstock Soapstone Company specifically for the

Woodstove Design Challenge. The primary design focus has been affordability, which we define as having a retail price under $2,000, and efficiency. Our design challenge entry meets our affordability goal, and

(1) is over 80% efficient (cordwood or EPA brands) with no energy inputs, (2) has EPA emissions of under

1 gm/hr, (3) has an owner customizable exterior, and (4) is easy to use. It has an innovative hybrid combustion design system which is described on the reverse side.

How much performance can be packed into a stove that is truly affordable?

Customer initiated designs can be as creative as the wild Moose

Stove (above) or the elegant Hollyhock Leaves (below).

8. First stove to offer a stove lamp so when the

power goes out you have HEAT, COOKING, & LIGHT.

V. MARKET APPEAL & EASE OF USE

1. Large fuel capacity and long burn times The

IDEAL STEEL Hybrid will easily hold 40 lbs of wood

and burn 16 hours or more.

2. Interlocking load door and catalytic bypass

3. Cooktop with variable heat outputs Heat from

the catalyst is pointed at the cooktop, front and sides

(NOT up the flue).

4. A single control for burn rates

5. Optional ash pan

6. Adjustable stove height in case you need to install

in front of a fireplace

7. Vents top or rear (uncommon in this price range)

8. Easy catalyst access (just lift the lid)

9. Carefully engineered smoke-free loading with

smoke flaps, air-foil baffle, and funnel flue collar

10. Next Generation catalysts made with 2100 degree

foil, no brazing, and high-temperature wash coat.

11. Advanced but simple hybrid design featuring

catalytic combustor, secondary combustion, and automatic catalyst air. Enhances woodstove experience by

providing viewing pleasure, increased output and decreased fuel consumption - plus clean burning!

13. Trophy Stove Design You want a wild design? A

big moose? A big fish? Your own stove buddy? We

can do it!

We make andirons to fit the overall design of your stove

3.2 cu.ft.Firebox

Hybrid Firebox Cut-Away

The IDEAL STEEL Hybrid has a secondary combustion

chamber that slopes up, from the back of the stove toward

the front, with flames easily visible from the front window. There is an almost infinite variety of secondary

combustion pyrotechnics visible in the top of the firebox

depending on the burn rate, amount of fuel, and damper

settings. Active secondary combustion is fun to watch

and a good teaching tool. Seeing secondary combustion

helps the stove owner/operator to understand the amount

of combustible material in wood smoke and the necessity

of burning it for efficiency and emissions control.

The catalytic combustor points at the cooktop

and front of the stove (as opposed to the flue exit), where

a consumer can get the most benefit from the heat it produces. The heat from the combustor spreads out at about

a 30 degree angle (like a flashlight beam). That heat is

captured in the cooktop and the stove body, rather than

going up the chimney.
