Rocket Mass HeatersArocket mass heater is a clean burning, high performance burner usually put together

using a majorityof recycled and/or natural materials, such as cob. Owners claim an 80-

90% reduction in wood usage compared to heating the same space with a metal wood

stove.

As opposed to the masonry heater which requires some advanced masonry skills, the

rocket mass heater can be built by any enthusiast with basic masonry and engineering

abilities. The only problem with this project is difficulty in getting a building permit,

because basically not many officials know what a rocket heater is. The exception is

Portland, Oregon, which has a buildingcode for rocket mass heaters, thanks to Ernie and

Erica Wisner, who share some hints onhow to acquire a permit on their site. Many

communities do have building codes and give permits for masonry heaters, so you might

need to treat your rocket heater as a masonry heater. Be cautioned, that without a

permit, you may void your fire insurance policy.

The rocket mass heater works on similar properties as a masonry heater. A fast, high heat

and oxygen-fed fire burn up the volatile gases and particulates, leaving very little

pollution, and turn almost all the fuel into energy. A bit of smoke is released during the

first minutes of a fire, until the temperature in the chamber is hot enough to burn the

combustion gases as well as the wood. The major difference between a masonry heater

and a rocket, is that the rocket stove has an insulated J- or L- shaped combustion

chamber that forces the fire to burn horizontally. The fire then hits a 90 degree angle at

the end of the chamber which causes a strong turbulence to rise up the insulated heat

riser, creating a strong draft that feeds the intensity of the fire. The heat riser sits inside

a barrel or larger secondary chamber which extends a couple of inches above the inner

riser, the hot rising gases hit the top of the secondary chamber, give off some of theirheat and then fall down the larger chamber's sides. The exhaust is then directed through

flue piping, usually set within a bench, which w ill absorb the last vestiges of

heat. Today's rocket heaters often employ cob, but there is no reason why you can't build

a masonry bench of brick, stone or tile. The final flue gas that escapes the exit is

basically water vapor. As hydrogen during combustion turns into water vapour.

Small pieces of wood, basically trimmings from one's yard, can be used to fuel the

heater. The spaces between the small pieces of wood allows more draft into the

combustion chamber, helping to fuel a fast, hot fire.

The combustion chamber runs horizontally, the flames and gases hit a 90 degree angle

and then throw off a lot of strong turbulence, which helps intensify the heat and create

draft, or a rocket effect up the heat riser. The heat riser is usually a smaller pipe set

within a larger pipe, the inner heat riser needs to be insulated as that creates a heat

differential which again increases draft. This heat riser is then usually set within a 55

gallon barrel, with the top exposed to give off instant heat, but there is no reason it

could not be set within masonry. (See resource below.) The barrel's lower half is often

covered in cob, to store the stove's heat and allow the heat to radiate slowly.

I love rocket heaters. Right now I only have an iron parlor stove for my little cottage but one

day I want one of these. I 've never seen so much eye candy on one web page before. Beautiful

heaters!

Hi Lauren, Or you could cover most of the barrel in cob, like the second photo from the top.

And then put some woobly piece of metal atop so the cat will quickly learn not to jump up. Or

the mesh as you say....I will keep my eye out for any examples. Best!

Reply #10 on :Thu February 06, 2014, 21:47:51

I'm curious if there is any way to somehow add an out mesh like screen about 3-5 inches away

from the exposed barrel that would help keep kids/pets from touching it and getting burned.

with some sort of small latch door so you can still get to the barrel if need be. I have a cat

and some day would like to add kids to the mix. ..I'm just not sure if the exposed areas will

be safe enough.

My mother-in-law walks naked in the house now that I finished their mass heater. The central

air just i s not as warm feeling, it i s dry feeling. Also it is cheaper to heat to a higher temp,

and that is why that wrinkled old bag has gone nude like in the old country.

What's the the smallest size RMH that can be used and still be efficient, I'm trying to make as

small of a square foot design or small foot print As poss ible. Can I make it tall and thin? In

maybe 3x4 foot area?

These look so stylish! And surely they're pretty efficient as well, as gas prices are going up,

this is certainly a good alternative!
