BIG JACK An extremely heavy-duty wood warm air add-on furnace

 

Jacks are one tough wood furnace. The fireboxes are made of 7-gauge (3/16 inch thick) steel. That's heavy duty. The firebox is cylindrical (round). It is near impossible for it to warp or burn out. They have an extra heavy-duty cast iron grate and are lined with 9-inch high firebrick. They are not to be compared to the lightweights from your local discount store. They cost a little more, but they don't have to be replaced every few years like the lightweights. Jack wood furnaces have been made since 1976. No one has ever requested a firebox replacement because it failed.

Jacks operate on a forced draft principle. Put some kindling in, light it with a match, and turn the thermostat up. That turns on the combustion fan to get the wood burning. Then load it up and relax. It's automatic from there. The room thermostat tells the combustion fan to start when it is not warm enough and shuts it off when you're comfortable.

A fan control mounted in the sheet metal plenum above the firebox tells the circulating blower when to start and stop. All automatically.

Is the Jack efficient? You bet. The right amount of the air from the combustion fan is directed to the fire. Twenty percent of the air (called secondary air) is directed above the fire to ignite the unburned gases and smoke created by the main fire. The result is high efficiency wood burning.

"Hi Joe and happy New Year, 
Just wanted to give you an update on the performance on my big jack. Well it's doing great. My wife is really happy that the house is at an even 74 degrees 24/7. We're burning about a face cord per week which allows us to eliminate about 90% of our porpane usage. I purchased a burn indicator and mounted it to the front face of the fire box. I'm maintaining between 350 to 500 degrees in the fire box which is giving me about 170-200 degrees in the supply plenum. On average we're at an 8 hour burn cycle for around 2.5 cubic feet of wood.

"We had purchased the Super Jack 125,000 BTU and does it ever put out the BTU's!! Our weather in upstate NY is cold and long. We have been heating our house with Fuel Oil and I have to say what a savings we will have now. Our house is around 2700 square feet and with our old heating source (Fuel Oil) we were always cold and conservative. Now we have lots of wood and are comfortable at 80 degrees. We really appreciate Keith who helped us with all our needs and Tech support when I had questions. These wood furnaces are A-1 in our book. Thanks Again."

"I would just like to tell you how much I like my Big Jack woodstove. I have had it for 19 years, it being my sole heat source for the first 10 years or so. Winters in the U. P. of Michigan can be cold, but this unit has NEVER failed me yet. Being a heating contractor I can really appreciate the quality of this unit,especially compared to the majority of other brands out there. I know of people changing castings in their stoves 2 and 3 times as often as I replace the firebrick in mine! I will always recommend your wood furnace to anyone that is interested in heating their home with wood. These days, there are not many products that give you the kind of value you will get from a Yukon wood furnace. Thanks again."
