Liberator Rocket Stove -- Hyper Efficient, USA Made Wood Burning Stove / Mass Heater
Rocket Heaters by Liberator LLC are the most economical wood stove to have ever been put on the market to date. Its design is a direct descendent to rocket mass heating technology. It uses 1/4 to 1/3 the wood a typical wood stove uses and can burn multiple types of fuel sources including tree limbs and large sticks and now pellets with the available upgraded pellet hopper. It's also UL Listed and 50 state legal as well as EPA approved. It's one of the cleanest burning wood stoves in existence. They are 100% USA made and ship for free! In this video I am doing an unboxing, review of the stove and a test burn. I have also included dimensions and weight to see if this stove will fit your application. This stove also applies for this tax credit!

Bureaucrats/regulators increase red tape/time/overhead (for your protection?), killing businesses. This goes unnoticed because it is not reported in the MSM. Why is it tolerated? FEAR of the private sector, based on socialist based politics taught without any counter arguments. It is in kindergarten - college. Don't like it? Don't trust your children's education to socialists.

To improve this stove you can add a "Sand Battery" to it which will allow it to continue to put out heat even after the fire goes out. Take a 6 to 8 inch pipe, cap 1 end, split it lengthwise down the middle, weld each half to the outside of the barrel and fill with sand. The fire will heat the sand and then the sand will release the heat.
Some run the exhaust mostly horizontal, up to about 12’ long bench, where it then exits a chimney. The bench I saw was not a bulky thing…it was 55-gal. Steel drums cut in half lengthwise, connected end-to-end, & used a barrel stove kit to make legs. Exhaust pipe went thru length of the assembled barrels to the chimney. Small gravel was bedded around & over the exhaust pipe, then tiles on top to sit on, or lay thin pads over. The whole thing could be emptied & moved, & was easy to clean around. The top of the smoke pipe outside, really does not get very hot. Most of the heat radiates indoors, from the rocket stove, keeping most of the BTUs indoors, anyway. But by using exhaust to heat a bench, almost all the BTUs stay indoors (& most critters love laying-out on those radiant heat benches!) I’ve waited about 30 years for someone to build a “portable” UL approved rocket stove! It took us about 2 years to collect the parts needed to line our dysfunctional chimney & get our new rocket stove up & running…this is 1st winter running it-we like it!! A 40# bag of pellets lasts a few days at current temps (in 20s or 30s at nite, & 40s during days)…we figure, burning the drop-tube-full of pellets takes about an hour or so…do that once or twice daily, 10 bags of pellets could go about a month maybe. Pellets are about $80/ 40# bag @ Home Depot. Compared with electric heaters here, we keep warmer, for less, even buying pellets. If we only used the wood collected out back, it would be free fuel. This thing is basically heating 1400 s.f. cheap-built tract house. It burns, gets the living room heated up, then starts to convert around the house…about 2 hrs after a burn, temps have more equalised around the space. That, despite us having to divide the space by installing doors with open transoms over them, in the hallways. I’d very much like to install a warm bench to make it even more efficient-but so much other stuff to get done!
Are you planning on doing a further review of this at some point? I'm usually a big fan of your videos, but to be honest this one seemed to be rushed and incomplete. Would love to see it installed with a proper chimney for draft and see how it performs.
I agree that was a was of time.
Did I miss something or was venting the smoke out of the garage via a chimney never discussed at all ?
No, this was a commercial. Notice he didn't actually show it burning anything either.
He did show it, but never talked about it. The vent to the chimney is attached at the bottom to the big round piece that he showed you could put a container of water on. The rest is up to you to know what you're doing. If not get a professional.
Right he never discussed how to vent or put up the flue for it.
I was thinking the same thing.
Will there be a complete video showing how this thing operates? That would be extremely helpful venting fresh air intake an actual application of it working etc.
So nice seeing a "review" not showing the burning and efficiency of what it's basically made for
This was a commercial. They hit him up(or he asked for it), gave him a free stove, and asked him to do a positive review in return. This was that and nothing more, a paid commercial. If I were the company, I would be pissed. He did a piss poor job, IMO. Also, who the hell has an unlimited supply of sticks < 1/8"? lmao Imagine requiring that to start a stove?
Was thinking the same thing…. He never got around to reviewing anything. More like an infomercial than a review.
@@gsftom happy to see i wasn't the only one seeing that
I assumed that he fked up the fire starting so couldn't show that part 😅

These are very do-it-yourself friendly methods that are super cost effective, but 1. Weatherstripping exterior doors and attic hatch.....and 2. Blown in attic insulation are often a huge help with homes older than 20 years. I cut my heating bills by 30% and eliminated drafts which made my home much more comfortable.
I started testing Rocket stove styles and materials about 10 years ago to heat a shop. What I found is there is no way to make the burn chamber and inside flue out of just steel. It must be lined with fire brick. I burned up a bunch of metal J=tubes in testing. The temperatures are so high even thick steel just burns and flakes away. I built my rocket stove out of a 100# propane tank J=tube style with 5x5 throat. The J-tube is all lined with firebrick and insulated with vermiculite. This is my 7 season with no problems. Most all Rocket stoves work just by design. Longevity of your investment may be another thing. Just some thoughts that may help someone.
Yea that's what I've heard about steel rocket stoves. The price is insane for the steel and the time it would take to stick weld it your self. Then again it's american manufacturing.
The new model the RMH-2 is actually lined with a ceramic fiber board refractory in the burn chamber and riser.
burn chamber made out of Crucible you cut bottom off
Yes... all burn areas MUST be fire brick. Where there is no contact with the wood, it is suggested that one use insulated fire brick. The more heat you can trap around the fire, and in the riser, the better. I've used a 55 gallon barrel as my "radiator." I didn't expect it to last 5 years since one end of it is above the riser, which gets up to 900°F, often. I inspect it when I clean the stove. It's still solid.
So this one will eat itself real quick then? Thanks for the heads up.
We had a Kuma wood stove installed in our home in March, we love it. Built in Idaho with u.s. materials, and has all the quality guarantees this liberator has. Heats the upstairs level of the house as well. $5800 installed plus a 1200 tax rebate and it looks really nice. (Part of the higher cost was bcs we needed more exhaust pipe and professionally installed) Been using it since Oct 13th, the furnace is set at 68, has barely kicked on.
This burns pellets for 12 hours unattended. Liberator is the only stove that can burn both pellets and regular cordwood.
@@suepaphly7686 Cordwood? Looks like the size is very restrictive and requires feeding a split of cordwood one-at-a-time... might need a union card to join the full-time fuel feeders club?

This thing's ADORABLE!!!! When it grows up, it'll be a Blaze King!
After 20 plus years of using woostoves to heat and cook with, here's what I've learned - thermal stresses on materials (steel, stone, clay, etc) can not be overcome. Steel will degrade the slowest. So, I built a rocketstove with schedule 60 8"pipe 0.5" thick wall (t-junction, elbow, 4'riser, collars professionally welded), recycled propane tank with rounded ends cut off to cover riser stack, 1" steel plate on top of riser stack that has been machine routed groove to prevent movement, a "hypocaust" masonary floor and wall for "thermal energy bank" with access for cleaning. And if you live in a humid area, you must burn short lived fires (10mins) at least twice a week during the warm seasons to help lessen corrosion. It would be even longer lasting made from 18/8 stainless at the same specs, but was out of my budget. I built the stove for a little under $1200, but many of the parts were purchased from scrap yards at scrap price. Heavy? Yes. Expensive? Not as much as you'd think because will out last my lifetime and the next generation's lifetimes. My experience tells me the stove shown in this video will burn out in 10 years with regular use. It does have "Limited" Lifetime Guarentee. Thermal stresses (expansion and contraction) are hard on materials. Careful folks - there are people who will always capitalize on trends, like all the preppers and some youtubers. It seems to be trendy to live "off-grid" these days, but Americans are programmed to consume the box, not think outside of it.
My woodstock soapstone stove has been going strong for over 30 years and still looks almost new. My brothers Vermont castings stove has been primary heat for almost 30 years and is in great shape. Not sure the assessment that steel degrades the slowest. The steel englander stove is by in the worst shape and it hasn't been used nearly as much. none of them have received the summer fire treatment though.. 1/4 a500 should last a good bit longer than 10 years.. Quality in any form isn't cheap
25 years with my Osborn insert stove. It’s also how you care for them
Good reply
The burn chamber and riser tube are lined with a ceramic fiberboard that is insulative and keeps the steel cool enough that it will not burn out.
Some of the commentors seem to be comparing their non-rocket stove to rocket stoves. I do not see the relevance. I wonder if they even understand the subject matter. DUH?
I am currently using a Wise Way gravity feed pellet stove which works in a similar fashion. Nice looking model and nice that it has versatility as an emergency cooktop. I did notice in the presentation that when he was inserting the pellet plate into the bottom that the plate was upside down as the basket should have been on top to catch the pellets coming down the tube. Overall looks like a veery nice setup.
I love my wiseway . love it. Did I mention how much I love it? Last one was electric blower, auger, room fan. My electric bill is $30 less per month. Bought WW second hand with chimney pipe INCLUDED for 500$ had to weld a crack and fix the burn basket . add new gasket seal . but so much better control .. I burn a bag a day in cold temperatures .
I'm confused on the pellet feeding. Does the entire top stay packed with pellets all the way to the burn pot? If so what keeps them from burning into the hopper
I bought the first one. Met dad and son at there shop in Missouri. Fit nicely in the back of my car. They are making the world better. Great guys. Great stove.

Looking forward to a long term review of this item.
Was looking to make my own, but gonna check this out first. Thanks for the preview!
If you make your own, your insurance company won’t be happy. Check with them before you build. The liberator is JuL certified and insursnce companies are good with it. But check your insurance company before doing anything
Wow. I’m a mechanical engineer. So I truly appreciate the design that went into this. Heat transfer, thermodynamics, mechanics of materials, manufacturing, etc. brilliant!! This is what America is all about.
Thanks for the review. Nothing like being inside a big echo chamber! You just need a few tons of "echo dampening material"! LOL! Cover the walls with more "stuff". Get more "projects going"
I'm a self-proclaimed rocket scientist. After watching untold YT videos on rockets, I came up with my own design, and built it. This is the 5th season I've used it. Other than periodic cleaning, it's maintenance free. I have it in my basement. It draws combustion air from my workshop, and thus, heated air moves toward it. .. gotta love a heated shop. My stove is followed by 35 feet of flue. Fifteen feet of it goes through a mass of block and stone. The stove doesn't blink at all this flue. It rips. The only mod I did was to enlarge the burn chamber so I could burn standard cord wood. I can get 4 pieces in the chamber, no problem. This was done after my failure, mentioned below. Rockets DO NOT have dampers or a way to control intake air. They MUST be able to draw as much air as they want, wide open. To cut back on this flow destroys the efficiency, and it causes buildup of creosote. A wide open rocket uses (burns) creosote as fuel, as well as smoke. When running at full efficiency, rockets are smokeless. What makes rockets so efficient is that the fire is small, but VERY hot. On cold winter days, all you'll see come out of the stack is water vapor. On warmer days, nothing, smokeless. I've plans to build other different styles out of curiosity. I did try to make a large, external burn chamber, of welded 1/4 inch (6mm) steel. It failed, miserably... 2 weeks work, poof... I cut it up. What I've learned is that where the fire is, you cannot have metal. Metal draws heat from combustion, thus, sacrificing the stove's efficiency. It must be lined with fire brick. The fire in rockets burns so hot it will melt steel... slowly, but my larger chamber mod is made of 6mm steel and it is slowly going away after 2 years of use. I'm concerned about the burn chamber on your stove. Pellets burn very hot. I did make a stainless pellet basket, and got the exterior of my stove close to 1000°F. That's too hot. I need to make a smaller basket. I am very curious about this Liberty stove, and what's inside the barrel. Is it brick? Ceramic? Metal? How do you clean it out? Super fine ash does collect in the bottom of the barrel. It must be removed in mine at least twice a year. My drawing board is full of sketches... ideas... Good luck with your purchase. A friend just sent me an ad for it last week. Thanks for the vid.
Nicely explained about rocket efficiency. Much appreciated as there are several on here that don't understand. The burn area is brick lined and all areas are accessible for cleaning.
Your design sounds similar to an oil burner we bought 20 or so years ago. It still works, I believe it is swedish. It burns hot enough that we turn down oil injection because you can't buy parts anymore but it burns through the burn pot every few years. We cut a steel wheel, weld together and remake a pot
Start doing videos or publish your designs.
@@live.life.simple. Thanks... I've studied intensely at YT University. Everything I know is right here on KZhead... I've an engineering mind, and just enough engineering education (2 yrs) to assist my designs. It sounds like the manufacturer did their homework. I am overjoyed that a rocket is available that is UL approved. I wondered if it would ever happen, given that all rockets are home made. Now.... will someone figure out how to get a rocket to do the proverbial 8 hour burn. Even with cord wood, I'm lucky to get an hour and a half burn, of which an hour is more typical.
@@markm8188 I may be retired, but have a ton of projects going at the same time, plus, keeping my musical chops up. Your suggestion is well-taken. I have thought of making my dream rocket, and doing a video of the process. Also, I'd like to remake my original, only with improvements, draw up plans on CAD, and sell plans, maybe even prefab the parts, sell them too. My retirement is a pittance, given that I was a musician most of my adult life, getting paid cash and living hand-to-mouth. Hard times scare me not... because its all I've known, got plenty of practice. Having additional income would be welcomed. Thanks for the inspiration.
Yay I got a notification finally!!! We have a fireplace in Florida but that looks very efficient and great for cooking.

Thanks for the info and demonstration.
Nice video and looks a stove for my next home!
Love to see more on this.
So when burning pellets what stops it from burning the pellets all the way up to the hopper? Had a pellet stove do that once before .
Nice video that is very informative, thanks for sharing. What I would like to know is, where's the attachment for the stove when it smokes?
Seems to be similar in concept as the gasification furnace I have which is a boiler that burns the smoke it creates. I would guess the water would be the mass in this case. This rocket stove is interesting for sure.
Would like to see you actually have a fire and use it

I've looked at this one and hopefully one day I can get one. I've seen where people say that they are ten times more efficient than traditional wood stove.
My rocket heaters use a third to half the wood, but the scrap hardwood flooring bits I use are $30 per cord instead of $300 per cord for split dry firewood.
Don't bother with this one, get yourself one from Europe.

If you were to burn this in your house or garage do you need chimney pipes or does it recycle the smoke and get a second burn clean enough not to need it
Will this get as hot as a regular wood stove?

That pellet grate was put in up side down, or the feeder will just push pellets allover. Other than that little mishap it looks very nice!

We had an Antique Potbelly stove in our shop. On cold days we'd have that sucker Glowing red. It was a 4 Bay shop and it'd run you out.
Interesting , New/different concept. I will say though that there are many wood and pellet stoves still built here in the U.S. and Canada.
The only brand that I have experience with which has All American Made parts is Harman stoves. Others have china made auger motors, exhaust snd convection blowers.
Now look up jet or rocket stoves and compare the burn methods. These are a whole different ballgame.
one of the key points of a RMH is to capture the heat from the exhaust....so showing it without the "mass" for absorbing that heat makes this part a rocket heater. Not a criticism; just want to be clear that this is "part one" of the rocket mass heater. And, it's the hardest part, so kudos for Liberator for making this bad boy! Very interested personally. But, my house wasn't designed to handle the weight where I'd want it to sit. My next house will....
I've read a lot of the comments before commenting myself. Are the clearances for this stove the same as a regular wood stove? Is the flue requirements the same as a regular wood stove or are they like a rocket mass heater would be? Also can this be attached to a thermal mass like a rocket mass heater. To retain or store heat over an extended period of time.? This would solve the constant need to refuel it.
Does this stove have any way of burning logs like a normal wood stove ???
I don’t know you from Adam but clicked on this video because of the stove but saw the one wheel and subscribed.
Ha! You are the first one to notice
I now notice life changing things easier ha. What an amazing tool for boredom. I’m almost 50 and just found it two months ago. Now waiting for the GT I ordered the night it was released. I’ve made several rocket stoves or atleast in design. A true rocket stove is insulated so it can retain the heat for gasification but I can call it an efficient minor stove as it is just that. Ride on.
whats the suggested square footage?
I have the previous model. Love it and burn pellets.
Thank you for the video.
You're welcome
The outlet low on the firebox side,? Is that for the chimney? I’m running a Kuma 80,000 btu wood stove right now. I know it weights more than yours more like 400+ lbs. the door is a glass like you can see thru . I’m in a 30 x 30’ by 3 floors with no appreciable insulation. Frame on fieldstone foundation new windows only means winter winds come in around them. Nice stove! I like to see the fire, it has a built in temp gauge and I added one for the stack.
Thanks for the video. A very good draw is needed or the fire will burn up the feed tube which I think is too long. Nice would be to see it working and how it is cleaned ie ash and fly ash
The new design had addressed that issue
Will it bur coal or anthracite ? We have wood but coal is much denser.
Could I burn wood shavings or wood chips in the pellet hopper?
Its the Business for sure
I'm considering a rocket stove But have serious concerns, How long of a burn will they burn on a fill? My Blaze king, will burn a long time with fairly good efficiency, I fill my stove in the evening when it is -30 C outside, and it goes the whole night and still going in the morning with lots of coals. Will a rocket stove do that? at 85 % efficiency of A Blaze king. I hate the thought of having to fill the stove every couple of hours, Now I heard you need to use fire brick to line these stoves, is that true since most people do not say anything about lining them when they build them One just sees the shell turning red, which I do not like.
Built one myself and they work really well. No creosote build up in flue and heats 1200 square foot pole barn on kindling
Good day Having grown up with wood furnace in house, I find these rockets stoves to be burning more air or more draft than from ordinary stoves , which makes me think they burn hotter but takes more fuel? Like turbo on tractor, more power, biut takes more fuel? Thanks
@@donvoll2580 The burn uses more air, and to use your tractor example, think about a Diesel engine, uses all the air you can give it (and turbo gives it even more) and you just regulate the fuel. More power/heat takes more fuel, but this is about the efficiency, not overall fuel use. The hotter burn creates a more complete use of the fuel.
@@brucea550 Well maybe. I live in Ontario & I was at a maple syrup demo, & they done something with evaporator to increase heat or production or more something heat ??? Thanks But a small amount of twigs is not going to give alot of heat all night. Thanks
@@donvoll2580 No, twigs are kind of a joke, I’m not sure why they keep using that as an example. I have a Solo brand camping stove the size of a coffee can that uses twigs to make a cup of tea or heat a pot of soup. It doesn’t necessarily take more fuel to burn hotter, just a more efficient burn. Same reason TDI diesel gets better economy. The problem here is some are comparing/calling a rocket stove a rocket mass heater, and the 2 are not the same thing. But with the rocket mass heater, you are burning a very hot fire, open draft (all the air it can take). And by the time that heat gets outside it’s been through 30 feet of stone mass that absorbs most of it. With a rocket stove, like shown here, and probably at the maple syrup demo, it’s burning super hot but not storing the heat, so way less efficient.
@@donvoll2580 This is why we added the outside air-intake ports to the feed tube on the RMH-2 models, from being a separate add-on component in the RMH-1 line; this reduces the draft from the (warm) inside-the-house air to something you can set up to draw from outside the home. You can also add a damper to the flue stack, which will result in an increased pressure inside the Heat-Exchanger and resultingly inside the burn chamber, which will slow down the burn a little bit. It will be a dirtier burn, because its not as hot, but it will burn slower. While our customer feedback reporting has been somewhat limited (people calling us) the average fuel consumption reported back to us is something along the lines of 1/4 to 1/3 the required fuel compared to an old-fashioned wood stove/heater. Our EPA 2020 results place us at over a 99% efficiency of burn (wide-open), and there are really only two other models which beat the RMH-2 in terms of efficiency of the burn, one is a cord wood heater with a catalytic converter, the other is a pellet heater with a bunch of electronics, neither of which can burn both pellets and cord wood, and both of which cost twice as much as the RMH-2.
If it’s used for pellets can it be direct vented like many other pellet stove? What is the Flue gas temperature when it’s running on pellets? Thank you all for building this in the United States this looks like a replacement for my Italian pellet stove can you make one of these with a water jacket?
My 80 year old Dornbeck wood burning furnace made in Cleveland Ohio is UL listed.
1- What is the longest timeframe you can stretch it out to, between filling up the "shute" ? 2- I understand it uses up alot of twigs/branches but will it burn efficiate with smaller split wood ? 3- is there a way to have it burn most of the night or when you are outside working without placing the Pellet attachment ?
Smaller split wood burns great. It's oftentimes the hottest burn you can get, including pellets. The only way to keep it burning longer is to somehow stack the feed tube to keep feeding some kind of combustible biomass into it. When making crates for these, we will often wind up with 4-8' long pieces of plywood, which we cut down to 2-3" strips, and those will burn for a few hours. The only way to keep it burning over night is to use wood pellets, with the pellet hopper; but if you add thermal mass to the exhaust pipe, such as through a bench, then you will still have stored radiant heat energy so you may not need to burn through the night, depending on your climate. Generally up to 15' of horizontal runs is acceptable in most areas.

Sooo many questions! Have built the clay/straw types in two of my homes before-with the steel recycled barrels and pipework to direct the heat(also packed in to clay/straw mix). Very time consuming. They worked fantastic, and since the top was huge and VERY hot, we would make breakfast on it every morning and keep our coffee hot while working inside. Now have a new home and wish to make another-NO clay in this part of the country, so looking for a different set-up. This looks like it will work! Questions: with these pre-fabs, where do the pipes hook on, and how far can they go before losing the heating, and/or require an end cap? Does this unit require a vent for exhaust also, and where is that joint on the unit if needed? Will the pipes need to be insulated/covered if they can be/are used? Looking at it, it seems to be stationary and heating is only near the heat source. Thank you in advance! I truly miss my old rockets, and hope to be able to benefit from another.
there are clear ports for all of the pipes. Make sure you make the exhaust as long as you can like you typically do a normal RMS. Tons of people put exhaust straight out of their building which throws away heat
@@gg-gn3re barrel needs to b removable to insulate riser for horizontal exhaust. surprised all r-stoves not equiped
There are 4" inlets on the feed tube for an external air-intake if you wish to build one on, and there is a standard 6" exhaust at the back of the heat-exchanger for your regular old black flue pipe. At about 4-5' from the floor, going straight up, without running through a thermal mass battery, exhaust temps average about 400-450 degrees F, with flue pipe temps around 200-220 F. The length of pipe you can run horizontally through a thermal mass largely depends upon the amount of vacuum you generate with your total chimney stack, roof shape, and wind conditions, but generally speaking, we don't advocate for more than a 15-foot run horizontally before going up a stack; we have heard reports of 20+ feet, though. Uncle Mudd is a good resource for stuff like that, as is Paul Wheaton at Wheaton Labs (permies.com). You can also get a little bit of extra suction by using a venturi-styled topper at the tip of your flue pipe above the roof; It works like a carburetor, where the cross-winds generate suction on the pipe below, which increases your burn temps, as well as how long you can run horizontally through a thermal mass battery. Of course, if you are running horizontally for any serious length, or for convenience's sake, we also advise putting in a clean-out on or near your turns. We've also added a removable top on the RMH-2 so you can vacuum out the interior of the burn chamber using an included 3/16" allen-wrench key. rocketheaters.com should have up-to-date contact info for Liberator.

My $1000 DS woodstove has a gasifier built in.. & I can burn coal. Wood burns at 500 degrees and coal at 1500 degrees and that will double when you open the vent. Amish built in Lancaster, Pa.
Is there a water input/hot water output option?
I am impressed with the cool rocket stove ♪
Fantastic rocket stove!! Is there an install video???
What size log's can you burn in it? Thanks
Dude! You installed the pellet grate UPSIDE DOWN! 😆
I checked; prices are insanely high, even with 25% down, for christlas on the website, it doesn't change this price insanity ! ! !
My good sir. You put the pellet grate in upside down. Nice stoves. I’ve got a gen one and love it!
Yep, I figured that out shortly after filming. Thanks for letting me know
@@live.life.simple. ten four! Happy holidays!
wish gen1 could vent horizontally,,,wd like to see smaller model also with 4in ex.
What is the btu that it puts out there’s no temperature control
How often does this have to be loaded when burning wood? My current Blaze King stove can go more than 24 hours before being reloaded, still has ample coals available to light the next load, and it is my only heat source. I love the idea of rocket stoves, and this and other designs are very efficient, but they lose some practicality when they constantly need to be reloaded. I'd consider this a nice addition to a garage, or some other space where you don't mind starting a fresh fire from scratch when you need to use the space.
I have a brand new (2020 build) Blaze King Princess installed this year that replaced about a 15-20 year old pellet srove and to be honest I'm kind of underwhelmed. For starters the blowr fan is way weaker than the old stove, you can barely feel it more than about a foot away (I almost think something is wrong but the phone support swears it's normal) and if I run it enough to warm the room I will be feeding it 2 or 3 times a day. If I set the damper really low I can get longer smoldering burn times but it won't produce a lot of heat. I'm kind of pissed because it wasn't cheap.
The liberator burns regular wood from about an hour to an hour and a half
@@beebob1279 Thanks, Bob. That's not bad considering the small volume of wood that is added to the feed tube. I'd love to try one in my garage.
@@benjamingamble2407 I want one in my house as an emergency heater. I have an insert for the fireplace. But, with blackouts that thing is useless.
Question: so i know that the design of rocket stove is to burn the fuel more cleanly, but over multiple uses, is there a possible of Creosote buildup which can lead to an unexpected fire similar to chimney fires?? does this type of stove require regular cleanings?? thanks for the review!
@MSTdesign354 Thank you for the explanation. I appreciate it :)
How long is the flue to the out side? Do they have a maximum length
Run the stack through a mass ( thermal battery ) and the only thing that comes out of the stack is warm moisture
The manual has details on installation, including the length of the flue.
That would depend on the installation, and the maximum length is actually determined by the amount of draft the flue stack generates. Without jumping off a cliff and getting into the physics and math behind it, generally, a taller stack is better, because of the higher (cross-)wind speeds which generates more suction, but generally-speaking, you can run horizontally for about 15 feet or so before going up if you want to add thermal mass in some kind of a bench so you can retain more heat inside your home. We've got feedback from people going longer, and getting temperatures of 80-90 degrees at the top of the flue stack with older models, which means that all the other heat is extracted and retained inside the home.... Talk about efficiency!
Thanks for sharing, there's a $750 deal off on the site right now.
I just watched this video. Have you installed it and if so could you make a video about it ?
I would like to see a small version of this that would work in a tiny home or rv.
wonder if they have a 45° fuel chute model
Made mine that is self feeding and pumps hot exhaust through concrete grade flat ductwork to a bench/bed. My place will stay warm for days once the fire dies out. Never a cold morning. See my photos link in appropriate playlist and vids.
how does the pellets get pushed in ...
can you build out an extended exhaust flue set insulated by cob etc to hold the heat after the fire is out to make it a true MASS heater??
yes, it is recommended
We used "kachel oven" in Germany. Construction is a little more involved but it would heat all night on the tiniest of fires.
In Belgium (the dutch part) we just call a stove a “kachel”. Does kachel has a meaning in German?
i've heard them called finnish stoves, russian stoves and generically, masonry heaters. does that sound like the same? haven't heard kachel before....thanks!!
Would've liked to see how the flue is hooked up.
Loved the video but could not help notice you installed the pellet great upside down.
Thank you ... I've been looking at some type of rocket build ... and these guy have it already built. One less thing for me to do, Again, thanks.
If you have the means build it yourself and line it with fire brick. You will thank me later.
@@TheCritterWindow Thanks ... I'm sort-of running into a time crunch. I'm considering several options, and this one is already built ... just back up the truck and make it happen. Again, I thank you.
@@dennisgodaire485 Website says summer of 22 so not ready to order.
@@TheCritterWindow Thank you ... Along with all of the other supply problems, in the country (and the world) , this becomes another one of my building materials that won't be showing up for a while. At least, my roof iis done and windows & doors are installed. .So now, I just might build my stove ... Thank you.
I have an idea to put 8 in stove pipe around the six and put a turbo plumbed into that with intake on the ground and exhaust up high and to cool the turbo with the intake air. Not sure if it's going to work. I could plum a little air into the intake of the fire chamber as well. I'm not sure if anyone else has done this but it sounds cool.
That sounds incredible. You would probably melt the top plate--we did, when we added a hair-dryer to the outside-air intake, and we got the top plate and the top of the heat-exchanger glowing cherry red, with the center of the top plate well-into the white-hot zone.
Pellets and wood are pretty universal . Does it burn coal when it gets hot ? Could you add a drip line for waste oil? (Also for when it gets hot )
As a part of the Liberator Rocket Heater company, I am proud to say that our testing (as well as confirmed by Guardian Fire Labs) indicates that our combustion temperatures are well within the range that would be required for burning such materials, as the design of the RMH-2 also required increased distancing from walls and the addition of fire-safe materials around it if it were placed inside those dimensions. However, our EPA 2020 compliance certificate also prevents me from suggesting that you try such things, regardless of how efficient, bad-ass, or economical such things may be. That said, we also believe in freedom, liberty, and the American Way, as well as American creativity and ingenuity--and that a person's property is essentially sovereign soil and that a person could do as they must or as they wish, and everyone else can and should mind their own business. *Liberator Burn-grates are not included as a part of the Lifetime Warranty, as they are considered a consumable product, and would certainly be exempted should any person attempt to burn coal in any Liberator model.
@@bli3366 most things aren't included in the lifetime warranty however I don't see the burn grates excluded so you might need to add one more thing to exclude. 3 years parts (1 year Labor) Fuel Feed Tube, Cooktop, Flue Collar, Burn Chamber, Ash Cleanout and Door, Air intake Assembly
@@bobvandersluis2503 I believe you're misreading the warranty... as the things you're listing are the things that are covered by the warranty, and the burn-grate is specifically excluded. We've hired out someone else to do the website, as we're all machinists, welders, and metal-workers, mostly; but the original website had a password issue that kept us from being able to update it. We've got a new website now, for the new model, and it's still being fine-tuned. Come spring/summer, we intend to learn from the lessons of the past and actually hire someone local at least part-time to be that guy for us. If you're interested in a job, give us a call.
@@bli3366 I was thinking if it wasn't covered on the 3 year warranty, it would be covered under the lifetime one. What is covered for lifetime then?
Thank you for sharing
How long is the burn time?
I've had an Englander pellet stove in my shop for a couple years now that's worked pretty well, so I wonder if this would be an upgrade over that, given the ability to use an exhaust heat exchanger and a stovetop fan. If heat output is increased but pellet consumption isn't (or is better yet reduced) I would seriously consider spending the money.
i also have an englander stove, it works great, but the auger motors seem to burn out every 6-8 months, despite the '4-5 year' life expectancy. i think its an hourly life span, with a maximum number of hours per day they are expecting people to use the stove. Its my primary heat source, not a 'oh its a little chilly today but i dont want to turn up the furnace' heat source. I cant complain too much. Got it for free. Bought a pelpro 2 years ago, and i had fully replaced the majority of major parts by the end of the first winter. Never buying Pelpro again.
@@dreamwolf7302 I've been using a PelPro 130 in my 732 sq ft shop for 8 years.. it's never broken down or required repair and from mid Dec to mid Feb it runs 24/7 (cause its -30c or colder)... I start heating in late Oct and finish mid April... usually 60ish bags. So another 2c on the PelPro... I love mine. Mind you it gets vacuumed every day, and a moderate clean (remove baffles etc) montly and a leaf blower vac (from the exhaust pie end) mid winter. Cheers from NW Ontario Canada
You can burn free sticks in this thing.
@@-whackd also that 😂
Can you burn saw dust, like the pellets?
sawdust is extremely flammable
Curious what the main chamber looks like inside . Never seen a stove with the exhaust on the bottom before
The exhaust is out of the back, the main chamber is a hollow chamber to allow for heat exchange. It acts as a mass heater by heating the air inside the larger tube, and this also causes a draft which makes it burn hyper-efficient.
smoke stack comes about an inch from top then its coverved with the outside skin you see.
@@suepaphly7686 Who are you? Works for Liberator or sells stoves?
This is what it looks like inside m.kzhead.info/sun/oKual6d5kKtmqGw/bejne.html
@@UncleMud thanks . Close to what I figured
Why didn't you also show how you hooked it up. Did you use regular wook stove tubing?
How good ya think wood chips would work?
What about emptying/cleaning?
Above all, folks, download and read the owner's manual before you even consider buying this type stove. Carefully note the fuel size required and that it must be re-fueled often. And by all means, read through the FAQs on the website. It seems to me to be very labor intensive to produce the size wood fuel required and to re-fuel it every 1/2 to 1 hour. If your plans are, as mine, to heat a shop, remember that it will burn down and have to be re-started the next day and then re-heat the shop. Whereas, with regular old wood stove, you will or should have embers still going the next morning. At least my old one did. It burned an average of 7 22 inch pieces per day and did not cool down overnight.
How do you exhaust it in your shop??
Where does the smoke come out of it? ie. where's its chimney? How does it work? Does that whole big main body cylinder get hot and radiate heat? So many questions...none of them answered by this video.
It has been almost a year, so it went through a winter? yes? Perhaps I have missed it, but was there a video on it working and a end of season over view of the steel components, Seems like a good video topic, even if bad.
Would be awesome to see that thing burn pellets! Is that not what that hoppers for? I think if I ever bought a pellet stove I would ask them to see if they could do a burn on site!
When will this item be regular stock after the 31st
