Liberator Rocket Stove -- Hyper Efficient, USA Made Wood Burning Stove / Mass Heater
HTML-код
- Опубликовано: 28 авг 2024
- 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!

Yes cz during our depression we can use it when electricity is shut off for non pay
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.
bwahahahahahaahahah
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 😅

With the power of editing, I doubt that. This is not his 1st video
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.
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? Love the UL approval and EPA emission compliance... Made in the USA... Kudos Liberator... keep the fires burning at home!
That is not a good price for a wood stove ... 😕

@@johnrogo655 2500-2900 ish. Preorder only.
I'm looking at this stove and I'm wondering how do you put a real peace of wood in such a tiny hole?
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.
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.
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'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 RUclips... 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.
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
That thing is $2900 with taxes incase you were wondering
Wtf you would build a log cabin and stove for that money. Thanks for the info 👍
@@markirish7599 haha yeah that's what I was thinking. You can buy other stoves kinda the same for $300 I don't see what's so different with this one. It's nicer but not $2600 nicer.
This thing's ADORABLE!!!!
When it grows up, it'll be a Blaze King!
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.
@@786otto The Gamera from Bulgaria is a really great heater I agree but it is not UL listed or EPA tested. It will pass those tests because it has passed the same tests for the EU but it needs about $50k in paperwork. I'm working on it. ruclips.net/p/PL9A0Ic1oNN_9brlvx8ra6_HdnUV8r1v5k

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.
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.
Yay I got a notification finally!!! We have a fireplace in Florida but that looks very efficient and great for cooking.
You don’t need a stove in Florida. All u need is a couple of tea candles and some clay pots.
Worst comes to worst, it's a good power outage heat source, and stove.
Full time job to feed this stove with little wood sticks
Good luck guys
it burns slow and hotter than a traditional stove.
It looks like the majority of the commenters don't know the difference between a wood stove and a rocket stove/heater.
Are you planning on doing a series on this? If not, at least a follow up video explaining the basics of the differences sounds helpful. Wood size seems to be a very important thing to cover so no one uses a "normal sized" chunk of cord wood should they encounter a rocket heater/stove.
Do you intend to add a mass for it to heat or just use it "as is" as a space heater?
Most of the rocket mass heaters that I've seen take quite a while to get going properly but once they are going need only an arm full of sticks to keep their space cozy all day or night. How does this slow start work with a shop area? Do you plan to keep it constantly heated?
I don’t know the difference. I’m sure we don’t use them in the U.K. though.
The Liberator heaters generally will start burning well once they've established a proper draft flow going through them. In the RMH-1's, this could take up to 15 minutes or so, but it is closer to 5 minutes in the RMH-2's because of the fiberboard insulation we use in the construction. Of course, this is also largely dependent on the natural draft established by the chimney/flue stack, which is largely dependent upon the air patterns created and established by its location on the roof as well as the geography of the area.
Adding thermal mass to a horizontal flue run, or around the heat-exchanger (the large round tube) of the Liberator will act as a capacitor in a DC circuit; there will be some resistance (longer times) to heat the place up, but it will also drain slower (more warmth) over longer times. This is actually independent of the burn, burn-rate, or cleanliness of the burn in Liberator models. Our in-house testing on older prototypes has exhaust gas temperatures of just over 400 degrees Fahrenheit with a flue pipe external temperature of 220 F about 4-5' from the floor with a straight vertical rise. This is notably better than other products out there, but is still a bit of a waste of heat going up a chimney that could be reclaimed using some added thermal mass.
@@bli3366 Do you have any longevity study's? What is the expected life of this stove? The amount of intense heat in a rocket stove is real hard on steel. What are you using to line the burn chamber and flue? Is it replaceable?
@@TheCritterWindow they only have a 3 year warranty on the parts that will burn up so I'm guessing it will only last 4 years.

@@bobvandersluis2503 Yea till it burns through the steel. This would be a wonderful stove if only they would use fire brick. I think burning pellets 3 years would be pushing it. Unlike wood pellets burn much more consistent. A constant blow torch compared to the ups and downs of wood.
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"
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 have the previous model. Love it and burn pellets.
Best part is the UL certification. I’ve followed this stove for a few years but I haven’t pulled the trigger to get one. I need to find a spot in the house where it’s out of the way
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.

I like this stove very much but I dislike the un-truths of "Free Shipping." There is no such thing. The cost to ship & handle items are *inside* the price of the item. If not, how are the people that handle and wrap up this product to get it ready to be shipped getting paid? How is the truck driver getting paid? Who's going to pay the driver for his/her fuel they must buy to ship this product all around the country? I guarantee if you ask any truck driver to pick this unit up in Kansas and drive it to Florida for free, you'll get hung up on or a door slammed in your face.
call it shipping fee included in price
Free shipping simply means shipping is included in the price, I think most people understand that.
It is nice not having to go to the order process and get slapped with a hefty shipping fee over and above the price you were expecting to pay.
Does kind of suck for the people close to the distribution center, but thems the breaks.
Uhh dude theyre getting packaged by the company making them, yes that price is in The cost of the product, literally every item you buy has the same included cost. The shipping though yeah the seller might foot the bill so its free for you. Realistically shipping is pretty cheap. We have a very developed shipping infrastructure.
I checked; prices are insanely high, even with 25% down, for christlas on the website, it doesn't change this price insanity ! ! !

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

It was a 4 Bay shop and it'd run you out.
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.
Looking forward to a long term review of this item.
Loved the video but could not help notice you installed the pellet great upside down.
Dude! You installed the pellet grate UPSIDE DOWN! 😆
The fact it has an option for pellets sold me. Would be awesome if it had an attachment to burn spent oil, diesel or other liquid biofuels.
Its really easy to make an gravity fed system with oil to any boiler. You need a good valve (needle type) to control the flow of oil. In order to prevent clogging of the valve you need to filter the oil if its not clean, using a fuel filter or similar.
Look at differnt videos on youtube, some conversions are better than others...

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.
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've liked to see how the flue is hooked up.
Thank you for the video.
You're welcome
I agree with some of the other comments. A demo wthout a flue?
How about a diagram as to the inner makings, so that the less familiar with the rocke principle gain a better understanding?
Also, unless the stove is lined, which in a stove that size couldn't be much, even 'efficient burning' needs to be fed repeatedly, whereas running the exhaust through real mass like a stone bench, is what stores heat efficiently.
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.
So, let's say I bought one and by some miracle the delivery guy helps me bring it inside the house; how on earth do you move this hunk of metal around to place it where you want? This should definitely be a kit
Can you tell me this will come in a larger size for large homes Sir ??? Thanks
Had me at Made in America
😁😁😁
👍
I would like to see a small version of this that would work in a tiny home or rv.
that is an awesome stove
Man, your toys are pricey! That freeze drier, and now this stove…..holy crap.
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!!
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.
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
Can it be used in a house
What is the venting flooring wall protection
I can’t find a number for the company
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.
I like your one wheel. I want one real bad
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.ruclips.net/video/mGagCAYy0u4/видео.html
@@UncleMud thanks . Close to what I figured
Liberator Rocket Stoves has a RUclips channel that explains more. Uncle Mud, the RUclips channel aslo explains well.
The idea is to have a mass unit filled with rocks bricks sand gravel n clay and run stove pipe through it once its heated it will stay warm n heat your space for several days without burn any wood thats where the real savings is heck you might be able to use the box it came in sort of to run your pipe and burry with rack brick n clay n straw miuxture and then your exhaust gas about 150 degrees will be low temp as well so you canvent it out a wall as no chimney is necassary. But I ;like the idea ov buying it rather then constructing everything with brick
Nothing is FREE, I'm sure the shipping is included in the price
I met them at the Rocket Heater Jamboree and he said its only for the presale.
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.
Yeah, i too was hoping to see what kind of flame it produces and how intense the flames get. I guess the company can produce their own video. Maybe they already did
Wood heat, is beautiful. The radiant warmth it produces will warm your bones. Wood is also carbon neutral or even carbon negative, since it lived as a tree taking carbon out of the atmosphere its whole life. Try that with other fuels. Wood heat is also self reliant, very safe compared to other fuels and can be burned very efficiently using no power, only a natural draft chimney. Wood scraps from projects can be used for heat. Wood is beautiful. Many good wood stove designs today are extremely efficient, burning nearly all the smoke which contains nearly half the energy from the wood.
Wood heats you 3 times.
Once when you cut it. Once when you stack it. Once when you burn it.
Lol. Yessir. The best form of cardio is chopping wood.
wood is carbon negative only if you plant a tree. Burning it liberates the carbon. However, just one volcano undoes all our carbon efforts in one eruption, so whats the point?
@@mikemotorbike4283 Trees remove carbon from the air their whole lives. if you have any charcoal in your ash you are carbon negative. Boom! you're welcome.
I am impressed with the cool rocket stove ♪
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.
I would love if they had a smaller version. My house is only 900 sq feet. I don't have space for something that big.
Would love to see an update on your installation and comments on insulation worries mentioned in comments? Super nice instructional video. Thank you, SkipRay, Kerry, Ireland.
Throw a bag or two of concrete mix under it and it will help heat up a concrete floor. I am curious if they make a miniature version to be used as a camp stove.
Would a sheet of Durock work?
@@glencaple3888 I've never tried it, I would probably go with some standard concrete bricks or something with a little thickness. The trick is to get fairly close to the firebox and maintain good surface contact to the floor as it speeds up convective heat transfer into the floor. Anything masonry would work as it stores heat well and is fire resistant.
@@MJorgy5 Installed a pellet stove a few years ago. Used Durock between it and a wood floor. No problems.
@@glencaple3888 Yes, that would be fine to protect a wood floor. I was referencing a stove installed on a concrete slab, likely in a shop or garage.
there u have it...u inserted pellet grate thingy upside down...so much for the design. made in usa.
Did all the ductwork come with it? Would like to see it all plumbed in your shop
does it have an insulated burn chamber???... if not it is not really a true rocket stove, tho it may be a good stove... there are endless stoves on youtube claimed to be rocket stoves, but i found only about one in a hundred fits the true definition of a rocket stove.... that being an insulated burn chamber, to create higher heat in burn chamber to allow more complete combustion of smoke and material, and thus greatly reduce pollution....
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?
The biggest problem with the Liberator is that, if you want to use wood as your fuel, the wood must be no larger than 1 1/2 inches around and you have to reload every 1/2 hour. This is WAY too much maintenance. It sounds like it works fine with pellets, but I have lots of free wood; NO free pellets. Just not practical for wood burning folks.
Hey, uh, where do you put in the logs? Wood stoves burn split logs. That way you can cut down a tree, split it all up, and have enough wood to last a household the winter.
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 :)
Your going to be spending a lot of time feeding the stove and gathering and preparing kindling. If you need to clear a jamb it doesn't look very user friendly especially when hot.
Another review after using for awhile?
Do a liveatream with one of their guys for Q&A. you'll sell a lot more for them if people get their questions answered.
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.
Nice
What are the required clearances?
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?
Nice video and looks a stove for my next home!
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.
@@bli3366 wood pelts 345.00 ton + cost of stove = turn up the furnace
@@OneAchilles So go clip some trees and get some wood. Have you seen propane/gas prices lately? Or heating oil?

@@bli3366 I have done and built may stoves from steel, I am well aware of the cost per btu for all three types of appliances- stoves - furnaces and the cost of fuel over 40 years.

Does this stove have any way of burning logs like a normal wood stove ???
So what is the largest size of wood that you can burn in the stove? It doesn’t seem very large. So someone with a good supply of split wood would not be able to use it unless they really broke it down smaller.
Maybe 4-6" but one piece burns much more efficient.
It works great with hardwood flooring scraps that cost me 1/10 as much per cord as firewood.
@@live.life.simple. More efficient than a quality stove with catalyst?
@@RayH- According to the EPA 2020 results, there is only one catalyzed wood stove that beat the RMH-2, and it costs twice as much.
To be perfectly fair though, it's really hard to improve upon the efficiency when you're starting off in the 99%+ ratings, which is where the RMH-1 was.
@@bli3366 I went to their website. That was disappointing, there wasn't much information. It looks like its being sold primarily as a pellet stove but with wood capabilities. It's not practical to be constantly feeding the stove wood plus the time needed to prepare the wood. I get wood chips free in my area. Those might work except for jamming. Do pellets produce less ash than wood? How often do you need to remove ash?
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!
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 .
Thanks for the info and demonstration.
I don't get it at that price point as its 2x3 times the price of a wood stove that will burn just about anything and run longer and provide more heat?
This is the only one that burns pellets and regular wood. It also uses 1/4 of the wood necessary to heat the WHOLE house.
I'm getting rid of my electric heater, so it's literally going to pay for itself in less than two years, especially with the tax credit.
@@suepaphly7686 I have experience with several stoves and the specs on this don't show that. I was excited by the idea but this dosen't come close to the mark.
I have run both the Gen 1 and the Gen 2 for about 5 years now. They really work well. I heat my 1800 square foot doublewide in Cleveland for $100 per year with one. It works best plugged into a thermal mass to store and slowly release heat. Check out my Liberator Playlist m.ruclips.net/p/PL9A0Ic1oNN_8Ieg4nqP3Yp3snRlmK9KEc
Ya we need a year update.
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
barrel should be removable at the bottom not at the top only....no smoke down there anyway and easier to replace clean or insulate riser
I have to wonder about insurance ramifications in an un occupied structure, epa approved or not. I'm actually really close to Brian, and have checked on wood burning in garages and shops. You will be hard pressed to find someone to insure you if they know about a woodstove in such structures.
BTW. I heat with a woodstove full-time in my house.
Its fully UL tested and listed to comply with all insurance policies.
Maybe. Better not store any gas cans in shop or garage. That was the main reason I was given when talking to insurance companies. My woodstove is UL listed. Still can't heat my garage or shop with it. I guess it would be prudent to do your due diligence and check with your insurance is what I was getting at
@@smh9902 so are most power strips and space heaters and they cause house fires all the time. My other half is a former insurance adjuster, anything you leave unattended is your problem not theirs as they see it.
I agree i heat my home with a wood furnace placed in the basement but my insurance company said they would drop me if i put any kind of a wood burner in my shop that is disconnected from my house to,
Use the wood pellets next time. A full on demonstration would be good
