Hello from Ireland.

I'm thinking about a design for a multipurpose rocket stove and I'm looking for any insight into whether the thing will work...

Basically,

I want to make this:


What you reckon

Just to add..

This is for my workshop. My dogs sleep next door and i want to heat a small water tank and pipe warm water through garden hose and into a big garden hose coil embedded in their bed (an old leather couch)

Also want to pipe the rocket stove exhaust directly into the bottom of an oil barrel full of wet logs. This will be wrapped in insulation and a pipe will be connected to a chimney running up outside.

The barrel will have a removable top for loading and unloading wood as it dries (or catches fire resulting in massive property(rented) damage??)

Eoin Fitzpatrick : Welcome to Permies.com/Richsoil.com, the Rocket and Wood stoves Forum Threads, and by extension the Cob Forum Threads. With over
28,000 Fellow Members Worldwide You can come here and talk with someone that wants to talk about what you want to talk about ! Their varied range of skills and
experiences will give them a widely, if not wildly different view. They will stretch your mind as you are stretching theirs !

O. K., we have a location, and a climate similar to Seattle Washington, and Wet!

Generally we want the rocket mass heater RMH, to be given pride of place, located very close to the Core or heart of the house. Location near Interior walls allowing
the best spread of the Heat from the RMH. Given that, and some original adaptation,how close to any one point in the Rockets footprint is the dogs bed ?!

Depending on the total area that a good location and Our build will allow us to heat, we can then size Your Rocket.

Were you thinking about actually using the stream of exhaust gases from the rocket mass heaters Fire ? Upps, we speak of the perfect fuel for Your rocket to be
Small, very dry, and finely split, This would give us a best water content in our fuel of 10%-20%, add to that, the production and combustion of the Wood gases,
adds additional Water Vapor with the Carbon Dioxide within the stream of hot exhaust gases.

So, we need a series of wood storage and conditioning areas, starting with outdoor storage protected with large building overhangs and even outbuildings if needed
to protect the fuel from driven rain and an increase of moisture content, Solar drying is always a plus when planing storage placement .

Normally we can cut our wood in the Spring, split and stack it and use it the following Fall ! But much of our ability to produce the Freaky high temps that
give us our great efficiencies and ultimate low wood fuel use is its reduction to small fine split wood for burning !

While every site and every build is different, after your RMHs heat has ben stored for later use in some kind of thermal mass, you will still have to plan on a final
vertical chimney located on the Lee or downwind side of the house !

While on paper I can 'prove' that there is a'sweet spot' for the chimneys exhaust to end just below the peak of the roof on the lee side of the house, we have to
accept that your final chimney will be exposed to winds that probably will not always be from only one convenient direction !

Short version, expect that you will need a final vertical chimney that ends 4'-5' over the peak of the Roof and 10' away from anything larger than a TV Antenna .

So take that all in, and give us a sketch and a few pictures to work with, and your fellow Members will help you find a final workable plan !

For the Good of the Craft ! Big AL !
