The Rocket Heater!
Please note: our Rocket Heaters come with both pellet hopper and air intake included. You will need to use the air intake if you are using the hopper. The air intake is the chimney connection that you can see on the side right under the hopper. It can take air from your room or you can connect it to a pipe that will take air from outside the house (pipe is not included). It fits a standard 4" pipe.
Height without the hopper is 36". height incl. the hopper is 55". The hoppper cannot be regulated (it's gravity-fed) and holds a full 40lb bag of pellets which typically lasts 12-16 hours.
This rocket stove uses about one fourth the wood a typical wood stove uses and does so by burning tree limbs and large sticks, while being one of the cleanest burning wood stoves in existence. This high efficiency is accomplished by maximizing draft and the oxygen supply, effectively utilizing similar principles that large scale metallurgical blast forges use to create steel and other industrial product. Most conventional wood stoves limit the air supply as to reignite the gases later. This obsolete system is hard to maintain, overly complex and are less efficient than Rocket Stove technology.
Our rocket stove uses a second principle of efficiency all other designs blatantly ignore, which is maximizing the thermodynamics of heat transfer. After all, a good clean burn is completely irrelevant if all the heat goes straight up the chimney and into the sky. Convection, conduction, and radiation (infrared) are the three ways heat transfers into a room. The heat is most efficiently transferred into the room by maximizing the volume of the stove which slows the gases to be exhausted, and maximizing the surface area of the stove the exhaust gases contact. This allows the internal gases to release as much thermal energy as possible.
The Liberator Rocket Heater creates a high draft, thus creating a 'forge' effect as mentioned earlier. With our unique design the cooler air escapes out the chimney, which is attached at the bottom of the stove, while leaving the hotter air at the top to release more of it's heat into the room. All this “thinking outside the box wood stove” engineering means that this Rocket Heater will often reach temperatures as high as 600 degrees Fahrenheit (315 degrees Celsius) in less than ten minutes from start. If you put seasoned hardwood in the heater, it can reach temperatures as high as 700 degrees Fahrenheit on the top plate yet the stove pipe remains well under 250 degrees. And it does this with nothing more than sticks, branches, scrap blocks, split 2x4's, and staves less than 2" inches in diameter. You can use this heater for a full hour or more without refueling if you use hardwood and around 45 minutes with branches and softwood. Starting a fire in the Liberator Rocket Stove takes no more than one minute with some practice, please refer to our user manual. With the Liberator Rocket Stove you're not just helping the environment and being more independent, your reducing the amount of time and energy spent in felling trees. If you're using fuel oil or propane, you know very well that you can't afford NOT to have this heater and even if you are using natural gas you simply can't beat free fuel that is readily available!
