Thanks again

For the 8 inch system you din't answer my question. With not enough heat exchange surface , i would to tell me like if you know what will be the problems ?

I do a lot of search, but If you search for pebbles you see from very small to medium size. I think that is better to use medium size as the ones that you send me in photo because small size will have air in between them and so they will act as insulation. Do you agree with me?
Also for building felt, i hear this from Ernie and Erica video and is not a tar paper . In search you can see roof tar paper. I think it's kind of cloth to protect your wooden floor from the first layer of bricks.
Thanks for your patience.

Pepples you mean the small stones found near sea. What is the size, can you show me a picture?

What do you mean is no good to extract the heat well. What is the actual problem , the half barrel heat mass may overheat or i may loose heat through exhaust pipe or the burn may be incomplete and i may have too much smoke in exhaust pipe?

Does anyone try to cut barrels with a jigsaw?
Does anyone knows what is build felt , can you show me an example, where can i buy it?

No you didn't understand what i mean to build firebricks, i mean how to join firebricks together to build wood
feeder , burn tunel and heat riser. How to glue firebricks together.

Also i have another few questions that are not answered , so if Max or someone else can answer i will be very grateful
1.If i decide to use simple earth for heat mass what type of soil is better to use for thermal mass?
2.How to cut concrete tiles and steel barrel without angle grinder?
3.what is build felt , can you show me an example, where can i buy it?
4.Is there any problem if i build 8'' system with only 4 half barrels?
5.If i build RMH with firebricks , how can i construct tripwire?

Hi,
I have some questions.
I would like someone to help me how to build firebricks with Clay. What is the best
mixture and procedure? Is there any video or give me some info that will help me?

I've found in internet to use: 1 cup clay + 3 cup sand + 1 handfull straw.
A local ceramist told me to use 2cup clay + 1 cup red soil + 1/2 cup sand + straw
You can see the clay that i found in my area in following photos:

How to cut concrete tiles and steel barrel without angle grinder?

Max, what is ISA. The system for the restaurant/bar in NYC is 6'' or 8'' system?

My conclusion is, the best for me, is to build in pergola an easy constructed system to make some tests.
Possible System to heat my pergola:
6'' system build with firebricks and insulate with cob.
Thermal mass: 4 Half Barrels in wooden mold
wooden mold fill with earth
on the top of earth one inch sand
on the sand glue slate rocks using clay(Sand+portland Cement)

Questions:
1.What is better to use on top of thermal mass, slate rocks or ceramic tiles or .......?
2.What type of soil is better to use for thermal mass?
3.Do you suggest to implement P-Channel and tribwire.
4.For base layers please see photo below and tell me any suggestions?

Also what is build felt? Ernie and Erica suggest to put it first on your floor.

Please make any other suggestions to improve the system.
Any suggestion is welcome.
Thanks.

Max, by earth you mean soil and what type of soil. I think it's simpler for me for beginning to use earth for
my heat battery. The second question about barrels connection i mean the connection of the main barrel with
the first half barrel see picture: http://postimg.org/image/kiclxip4p/.
Make a bell you mean to connect only one half barrel and make several bells , you mean to connect several half barrels
with exhaust flue at the end to enlarge heat mass?
If I can’t heat Pergola and ground and first floor about 205m² I think to build a 6’’ system with 55gallon barrel to heat only my pergola or an 8’’ system with 55 gallon barrel to heat my pergola and ground floor. an area of 25+90=115m².

About the area that i want to heat.
Note my Pergola will be closed with vertical tents, see picture as example(not actual picture):http://postimg.org/image/owiskhn09/
Also pergola is located to South of house and all day is getting hot by sun.( at Cyprus we have sun about 300 days of the year).
The problem is mainly during night that temperature is between 3-10 degrees celcious.

Also in the following picture:http://postimg.org/image/llwq9h9rt/ you can see a schematic diagram with dimensions of the areas that I want to heat. Please advise me if it’s possible to heat Pergola and ground floor using a fan to push hot air from pergola to ground floor of my home through the door that connects them.

Soon i will let you know about the materials and sizes i can find locally.anks.
Thanks

I paid for Rocket mass heaters 3rd edition but i don't know how to download it.
Please help.

Max i have another few questions about half barrel system for a restaurant/bar in NYC.
Does wood round heat mass limits heat transfer? Is wood use only for aesthetic reasons.
Wood is very beautiful but does mass heater perform better leaving it without wood?
Any dimensions about the radius of the half circle that is cut on barrel for exhaust gasses?
(55 gallon Barrels)
Thanks

The system with half barrel horizontal loading that i was referring was the one with two half barrels. This system has horizontal loading.
http://donkey32.proboards.com/thread/560/half-barrel-system .

The system for a restaurant/bar in NYC is the system that is best for me. Traditional Rocket Stove at the one side connected to thermal heat mass using half barrels. That system is great.
I don’t want to put barrels directly on my floor, any idea what to put first? Is it good to put 5-8 cm cob with straw first and then half barrels?
I read that straw is a good heat insulator and so we put straw only in cob under barrels but no in cob above barrels, do you agree?
Does firebricks that need to build heatriser are different from the firebricks of Burn chamber?
How to create a cleanout for ashes near burn chamber in the side of mass heater with half barrels?

I need help if anyone can help me, how to heat rooms of another floor. One solution that I think to use is with air ducts. If anyone else has any other idea is welcome.
Max please tell me your opinion for the following solutions:
The first solution is to pass air ducts through barrel. See picture:
Air ducts inside barrel

The second solution is to pass air ducts outside barrel. See picture:

I agree it’s very important to remove the paint and oils from the barrels before use. Since iam going to use half barrel system for thermal mass, from what you said it will be better to remove paint from main barrel and the first half barrel of thermal mass, because heat may be high at this position. Do you agree?
If i understand well for the heat mass is good to put materials with high thermal conductivity and cob that holds heat for hours?

Tomorrow I will download the pdf file try to find all the materials and if I need more help I will contact again.
Thanks a lot , very useful information.
