Wow, I never knew. We have a massive masonry heater in our home my father built. He passed when I was young so I never knew the details. What I thought was just a fancy fireplace has much more thought put into it than I ever thought. Thanks for the info.
We live in a old farm home built in 1949, and we have something like this. We might be able to own it soon, and my husband keeps telling me he's going to convert this into a masonry heater/ stove. Now I know what he means. Thank you for the information.
I dunno if these designs incorporate this but you wanna bring in some unburnt air to mix with the flue gasses above the fire for secondary combustion, this halves the amount of soot and particulates produced and increases the efficiency of the burn by a lot. The designs that take some air in from the door might do this. The ones that only get air in from below are the old fashioned type. On my finnish built one there is a slot infront of the firebox that goes down into the ash pan, where primary air is sucked in, so part of the air goes up this slot and flows up infront of the fire instead of through it, then it can mix with the hot flue gasses and combust a 2nd time. We've had our chimney swept once since 2014 and the sweeper said it was almost clean.
holy bat stove! i have never heard of these or seen them. love it!!! now I am going to google it.. and may add this to our remodel! thanks for taking the time to show us
Very cool video. I had never seen anything like this before. You could incorporate a smoker (hot and cold smoker) into the unit as well as an oven and a cook top. This is the perfect way to go. Going to have to look up design plans and learn more about it. Thanks for the idea!
6:06 This is one beautiful arrangement. Do I see an auxiliary stove top system on the right? If so, how does that work and does it have a separate firebox sharing the same flu?
Thank you! Could you please help us to find online to purchase a Cast iron oven insert for a brick masonry wood stove. It’s also called Bake oven inclosure It’s pretty much an Oven Box with the door, that made of cast iron or metal insert in to the space left in the brick wood stove.
Thank you for video. How would you clean crosote, if any, from flue. Or does high temperature ensure no build up of creosote. If masonry has cooled down from lack of use, is it difficult to light fire. Is there sufficient draft ?
I have a masonry heater and you don't get much creosote buildup because of the high temperatures in the combustion chamber. But if you did you would just clean out the flu which is a metal stove pipe the same way you would any other chimney.
Chimney fires are typically a concern for metal chimneys and typically short chimneys. Because the metal CAN melt or be destroyed by the fire causing a housefire. And with shorter chimneys the creosote can build up close to the exit causing fire, embers, and sparks to exit the chimney and catch the roof on fire. Masonry heaters don't typically have these issues because the creosote is deposited on refractory brick very early in the cooling process. Therefore if it catches fire it just heats the brick up causing no damage and is too far from the final exit to spit sparks and embers onto the roof.
I notice the masonry heaters you show have glass doors on the firebox, an advantage over a rocket mass heater, plus do they burn larger wood? And do they use ceramic glass, to take the high heat? Our house has a fireplace with a metal back heatilator, which is only moderately efficient (see my video). I do burn short hot fires which heats up the house, but doesn't heat the masonry mass well. Unfortunately to convert it I think I'd have to tear the old one out and start over, but it would be easier to build a masonry heater than a rocket mass heater in the same space.
With the high temperature of around 1500 degrees Fahrenheit all the hydrocarbons are burnt off. If operated correctly, only fly ash should be visible. Cleanouts take care of access. 1500 degrees in firebox but about 350 degrees at chimney connection. All those BTU's are stored in the mass.
I have a similar type stove and I'm wondering if it is possible to convert it into a rocket stove and it seems like not have you dealt with those? I really don't understand why anyone is using a normal wood stove or I think like you have when there is such an amazing technology as rocket mass heaters
The creosote buildup that causes chimney fires will not burn hot enough or long enough to have any negative effect on refractory brick. Because masonry heaters effectively have a gigantic network of refractory tunnels before exhausted up the chimney, chimney fires aren't as much of a concern. All of the creosote would build up on refractory brick early in the process, and if it lights up would simply burn off.
There is no creosote to deposit. To get creosote, you need smoldering (non-flaming) combustion, which produces tar droplets (particulates). In masonry heaters, you do get a small amount of particulates, but they are soot (elemental carbon) instead of tar (organic carbon). This is because a masonry heater only operates at high burn rate, and cannot be turned down to the point of smoldering. We know of one that has been in continuous use for 37 years without requiring chimney cleaning. It has maybe a 1/8" layer of soot deposit on the flue.
i´m currently building a house and i was going to build a fireplace. Now that i have found the masonry heater / russian stove. I´m sure this is the way to go. Where can i find schematics on how to build one?
Hi there, can you send me the blue print of this heater? I am from Kashmir and we do not have the know how of constructing one of these. But the temperatures do fall to the same extent for sure.
hi there, is it possible to put a broiler on top of the fire place so it can heat up the entire house instead of the room where is the fire place located?
If the fireplace is placed correctly in the middle of the house it will heat much more than that one room. It will radiate heat trough the house even 10 hours after the burning has stopped. I know few of these where there is waterpipes inside the masonry (between the core and sheating) and connected to the boiler reservoir so they can heat their shower water etc with that oven.
Indoor and outdoor air maybe used but regulations may require outdoor in some cases. Check with your local regulators or communicate with a Masonry Heater Association member in your region.
Nooooooot necessarily. "Massive masonry stove" is the general term, encompassing the Russian designs (both the vertical and the horizontal bed style), but also designs from Germany, Scandinavia, and other areas. A Russian wood stove could involve brickwork like this one, but could just as easily be a little cast-iron box, with no masonry involved-- a totally different animal.
They are similar. There are different systems of masonry heaters that have origins in various parts of Europe. This design, known as a contraflow, originates in Finland. Rocket stoves have a combustion system based originally on a continuously fired cookstove, invented by Dr. Larry Winiarski in 1980, based on an earlier design by Sam Baldwin.
Off he talks any slower and without enthusiasm the world will stop and start going backwards I'm asleep now ibet there some great conversations in the winter wlth him lmfao
it's a pretty common thing in "the old world". we all have our regional flavors but it's essentially the same concept, use a long pathway through stone or masonry to store heat from a fire. if the system is perfectly tuned the exhaust from the chimney should be room temp theoretically. there's stories of Roman concerors in England doing something similar, but they mostly just heated the floors by running hot gasses in channels in the floor masonry, they'd have slaves fire up the system from outside the house
1) There isn't much to sweep since masonry heaters are always fired at 100% with no choking or tamping down. 2) There's always a cleanout 3) You can always sweep from the top Plus, did your apprenticeship teach you to write awfully in all caps and with excessive spacing?

RIP to your father. He must have been an industrious man.

06:07 the design of this one is magnificent, I really wish to find more of these elaborate designs for masonary fires.
What a wonderful explanation of a masonry heater’s function!

Expensive boiler and stove manufacturers dont like these videos....this is planet saving stove heaters...thnx for posting
holy bat stove! i have never heard of these or seen them. love it!!! now I am going to google it.. and may add this to our remodel! thanks for taking the time to show us
It has many names. You'll get more results when you use more names, "Russian Oven" is how I've known it.
We love them here in north europe.greetings from 🇫🇮
Lovely warmth. And a beauty to look at.

"Kakelugn" is what he's saying at the end... it's swedish and is directly translated as "tiled oven"
Thank you! Could you please help us to find online to purchase a Cast iron oven insert for a brick masonry wood stove.
It’s also called Bake oven inclosure
It’s pretty much an Oven Box with the door, that made of cast iron or metal insert in to the space left in the brick wood stove.
With the separate chimney, I would assume that the heater could be added and attached to an existing brick fireplace?
Thank you for video.
How would you clean crosote, if any, from flue. Or does high temperature ensure no build up of creosote.
If masonry has cooled down from lack of use, is it difficult to light fire. Is there sufficient draft ?
LOL I see he answers questions in a rather quick response.

Excellent video.
I am also quite interested to build a masonry heater.
What temperature does this one get, to ensure the complete combusion?
Internally, they can reach around 1,800 F.
The Germans that went to Russia in early 1800's had these in their homes. They also had their beds on top of them that kept them warm at night.
A cat had to be lying on the heated bench lol 🤣

I really don't understand why anyone is using a normal wood stove or I think like you have when there is such an amazing technology as rocket mass heaters
This is not a normal wood stove. Rocket mass heaters are not legal everywhere
We watch similar content ha
Depending on who you ask and how they were designed, these are more efficient and imho more aesthetically pleasing.

What did you go with??
I JUST FELL ASLEEP IS IT MORNING ?
Snore. He killed it. I kept thinking about the SNL NPR skit with those two women talking slow about schwettie balls
Hi there, can you send me the blue print of this heater? I am from Kashmir and we do not have the know how of constructing one of these. But the temperatures do fall to the same extent for sure.
so what are the indirect and wide? ovens?
We heat with a masonry heater
hi there, is it possible to put a broiler on top of the fire place so it can heat up the entire house instead of the room where is the fire place located?

Love the cat endorsement
They all either seem to have a cat or a dog on them. Might as well build them their own bench. LOL
класс!
Do you use outside air for combustion?
Indoor and outdoor air maybe used but regulations may require outdoor in some cases. Check with your local regulators or communicate with a Masonry Heater Association member in your region.

A lot of good information. Thanks :)
How do you clean it?
With fire, I'd imagine.
@@Thalanox The most amazing way to clean ANYTHING!
At 2:00 min in the video is how
These stoves completly turn everything into fine white ash and it blows away
In Finland we call it "leivinuuni"
What is the difference between this, and a rocket stove mass heater?
They are similar. There are different systems of masonry heaters that have origins in various parts of Europe. This design, known as a contraflow, originates in Finland. Rocket stoves have a combustion system based originally on a continuously fired cookstove, invented by Dr. Larry Winiarski in 1980, based on an earlier design by Sam Baldwin.
What are your favorite book references on the topic?
Off he talks any slower and without enthusiasm the world will stop and start going backwards I'm asleep now ibet there some great conversations in the winter wlth him lmfao
I bet a lot of the inception of this type of heater derives from typical Russian stoves.
it's a pretty common thing in "the old world". we all have our regional flavors but it's essentially the same concept, use a long pathway through stone or masonry to store heat from a fire. if the system is perfectly tuned the exhaust from the chimney should be room temp theoretically. there's stories of Roman concerors in England doing something similar, but they mostly just heated the floors by running hot gasses in channels in the floor masonry, they'd have slaves fire up the system from outside the house
Only 10 °
:
If you were a real mason you wouldn't have dutch-mans in your brick work.
No one actually show's how to build or how it works. 🤬
👍☹guess I skipped it😫☹😟
Russian woodstoves is the real name
Or finnish or norweigan or swedish.they are all over up here in northern europe.
THEY WON'T TELL YOU HOW TO SWEEP IT !!! CAUSE THEY DON'T KNOW HOW !! I KNOW BECAUSE I AM A MASTER SWEEP . THEY HAVE NEVER SWEEP THERE'S !!
Yup, your Caps Lock is working well. You can press it again to turn that off.
1) There isn't much to sweep since masonry heaters are always fired at 100% with no choking or tamping down.
2) There's always a cleanout
3) You can always sweep from the top
Plus, did your apprenticeship teach you to write awfully in all caps and with excessive spacing?
