Frequently Asked Questions

Are concrete pads required?

No, concrete pads are not required.

A firm level ground with a solid concrete block under each leg is all that is needed.

Will the stove corrode?

The stove is made out of mild steel, as you know mild steel left untreated will corrode. We use Sodium Nitrate for corrosion protection. Basically, Sodium Nitrate removes oxygen, and without oxygen there will be no corrosion. We maintain the levels of Sodium Nitrate by requesting two water samples, from the water jacket, per year, (a minimum of one a year is required for the warranty). The test is free, we are checking the dilution of Sodium Nitrate so we can let you know when you need more. On average you will need to add half a gallon per year, which will be about $30.00.

What materials are used to make the stove?

We proudly re-purpose a 500 gallon propane tank into a fire box. By doing this, we save you about $1000 in new materials and labor. Propane tanks are 3/8″ thick, one of the thickest fire boxes available. The tanks are rated for over 215 PSI, which is way more than needed. It is well known that the strongest structural design is round and the weakest is square or rectangular. This pertains to boilers as well. For longevity and strength our propane tank uses this round boiler design. Round designs have fewer welds and this is very important. Square or rectangular designs with many welds and faceted corners, could be problematic. Our water jacket is a round design as well and is 3/16″ thick. The jacket is insulated with spray foam for greater efficiency; and it completely surrounds the firebox. The larger outdoor stove has a large steel 24” x 24” door and is insulated with 2200 degree ceramic fiber insulation. The chimney is 8′ schedule 40 steel, 5/16” thick. Welds are 100% penetration. These are some of the heaviest built outdoor furnaces available – anywhere!

What are the daily operations?

Following simple daily operations will increase the performance of your stove. Everyday, before you load your outdoor stove, you will want to pull the ash and coal pile to the front of your firebox. Make it into a heaping pile, then load your organic fuel on and behind the coal pile. The fire will burn through the coal pile and into the fresh organic fuel, burning coal to ash much better.

Another benefit of raking ashes forward each day is that it will make it easier when you need to empty the ashes, ever 4-6 weeks. The ashes will already be in the front, and more of the firebox is available for heat transfer to the water jacket. This will make your outdoor stove work faster and burn less fuel! If you allow your outside furnace firebox to fill half way up with ashes, you will minimize the heat transfer area and will have a tough time finding room for fuel.

How many square feet will the stove heat and how often do I have to fill it?

The 4000 Square Foot Model will heat the average home, pole barn (up to 30′ x 40′) and hot water heater. Using seasoned oak, this model should give a burn time of 15-18 hours in the middle of winter. Spring and fall seasons, much longer. The quality of insulation, windows, type of fuel used, etc. could effect the burning time.

How does the stove heat my home?

The furnace is a burning stove that sits in your yard. Normally 50′ – 100′ away from your house. It burns organic fuels and heats water that is in the water jacket that surrounds the fire box. The water is pumped through an insulated line that is buried in the ground and attaches to a furnace coil, like a radiator, that is mounted in the duct work of your home.
When your home calls for heat, only the furnace blower turns on, blowing air through the furnace coil and heating your house with the heat created in the stove.

What issues have you had with your stoves?

While we have addressed the issue with our newer stoves, the older stoves had cracking issues from over heating the stove, we do have a solution for these stoves as well.

The biggest point of failure is the electrical solenoid, we strongly recommend keeping a spare solenoid on hand in case of failure. This is an inexpensive part, simple to change, but can prevent the stove from operating when it fails.
