modifiedchevy: what if you lined the whole inside with say styrofoam that will burn up later, took a 6"cardboard tube and a 12 or 14" tube for the burn tunnel made an L , insert into stove, and filled the remaining airspace with ceracast... insulated firebox 360* minus the door for loading. and you wouldn't be ovefireing the cast iron and possibly creating a fire hazard in a couple months time...
Sooty Sweep: How about more mass on the inside of the stove.
life and death: I think just covering it in mass would be good. I'm going to try that out with a cheap small stove. I'm trying to get the cooking area of your typical wood stove on a rocket mass heater. Anyone have any other ideas?
70kirkster: Very nice work. Thanks for sharing your results. I'm currently building a rocket heater with a large, insulated firebox for the exact reasons you discussed.
William Frawley: I have this same stove. What do you know about it? how old is this stove?
Erin Owl: Thanks for sharing this video and the explanations. It is very helpful.
grapsorz: You need to retrofit that Jøtul with a "clean burning system" and then it will burn just as clean AND slower then a rocketstove.
The optimization is needed to be don in the wood stow and not in the back part. the conversion of the stow is don by insulatin the sides then introduce the preeheated air in to the top and to the roof in the front befor the flame goes up in to the uper "burn chamber" then you get a compleet burn as long as the woof is not to wet. i use modern Dover burners that work just liek that.. mine is a smaler one. (the one you have trhere is the old 60cm type) stil it burns complete and heat up realy good.
What i dooo need is somthing to remove more heat from the the gasses goign out from it. now it just goes out the back and out thru the wall.. so a lot is lost to the outside.
Roger Buchan: to much fule or (wood) being converted to gas at one time the burn will be rich
Sue Woods: What about in a room added onto a mobile home. I have mt wood furnace in there but go through a tremendous amount of wood. I need some help.
John Ah Kuoi: whatif, you had the rocket mass heater before the stove?- you get the clean burn first before it entered the cooking stove? ....
cbzombiequeen58: problem , ive only got a 4x4 space to make a rocket mass heater.instead of going sideways for the mass I need a way to make it all in a 4x4 square.this square is in the middle of two rooms.the floor is wood. the whole house in on 4x4 that are cemented in .we were going to put in a regular cast iron or metal heater but I like the rocket mass heater instead.worried about if this small mass would heat 28x32 house.and need plains for this square unit any help would be great were lost
Bev Miller: So can one take a wood stove and fully envelop it in thermal mass to create a more efficient thermal mass hybrid approximating a RSMH?
Omega Survival Supply: it'd be nice to see diagrams or a more thorough explanation of how you built. thanks for the vid....just subbed.
pandoraish: I was hoping someone would answer this, I was thinking the same thing! I just bought a small cast iron stove before finding out about rocket stoves. It would be nice to incorporate it.
unkulmark: How much would it have increased the efficiency if Ernie would have added stacks of bricks along the sides & top of this wood stove? Has anyone tried covering a rocket hybrid wood stove in cob to increase the mass?
MrHottleaded: I have never fed a wood stove more than three times in a day.
paul wheaton: Much like a conventional stove, you start the fire with kindling. Once that is gone, add some bigger stuff. By that time, the room is plenty warm and you stop feeding the fire. The room stays warm for a day or more. Feeding the stove every half hour is what you do with a conventional stove, not with a rocket mass heater.
MrHottleaded: I'm like you, I don't see truly how a rocket stove is useful with all I have read seen you need to feed them trigs every half hour. I don't have time to baby a rocket stove I have things to do like live. i Europe a masonry wood stoves have been used for 100s of years and can heat your water too.
M M: Wouldn't you be able to achieve your highest goal by covering the entire body of the stove with cob?
wood stove + rocket mass heater = hybrid5
