I will begin with the context of our anticipated build...we live in a fairly experimental, some might say rough, situation...it works for us...but here it is...
Hm, what else might be applicable...?
Yes, so, we obviously don't have much space. I don't even know that a mass would be workable for us. Certainly not 10m of mass encased flue. And we don't really anticipate using this heater any more than a couple dozen times...tops (but who knows). Hopefully next winter our new addition will be all good to "rough it" with her parents (we enjoy our layers of woolen blankets).
Some concerns:
We would prefer to do build something that is mostly cob. I haven't been able to come across any firebricks. I ordered some perlite (only 20L as it has been difficult to come across and quite expensive, but more could be had if need be). Um, I have two 100mm diameter, 1200mm lengths of flue pipe, one of 240mm diameter, 1000mm long, and some 150mm diameter flue pipes.
I have a 60L drum I hope to work with, measuring 380mm across by about 570mm high. According to all the research I've done over the past weeks, it seems it'd be tight, but perhaps with a raised cob core it could be workable (if I go with a J-tube design, but wouldn't mind an L-tube if you educated folks suppose it'd be better).
Yes, I will gladly post some photos of the structure and site if it might assist any of you (to assist us!).
Please, please lend us your wise suggestions. We feel like we're pretty handy folks and strive to take care of ourselves as much as possible. We entering new territory here though - with heaters...and babies - and we just want to get some advices from folks with experience.
Thanks in advance.
Cheers! Art.
- My partner and I live in a technically illegal <10m2 (100ft2) wattle and cob (ish) structure we built beside our garden we've developed on a friend's property.
- The structure is comprised of four chunky green eucalypt rounds buried a meter in the ground with poplar/willow poles running horizontally (rather than vertically) at about 20-30cm spacing between the poles originally intended to support the cob, which is only about 10-20cm thick (depending on spot, highly irregularly applied, with curves in walls, etc.)
- The footprint was dug out about a spade's depth, backfilled with broken clay drainage tiles, covered with race lime, and then we put just a 100mm cob baselayer floor (next spring/summer we'll do it up a bit better, but winter was approaching and time was running out)
- We live in temperate New Zealand - we get the occasional frost but it really doesn't get below freezing very often.
- We have a roughly queen sized mattress/bed that is simply a duvet cover stuffed with straw (ie, highly combustible) and this takes up half the room.
- The ceiling/roof is simply corrugated iron sheets laid over round, hardwood pole perlins
- No electricity, absolutely no desire for anything with gas, so in search of a wood heating option
Hm, what else might be applicable...?
- Oh, yes, we don't mind the cold in the least and have no interest in a heater for our own comfort...but we'll be introducing a baby into our lovely (unheated) environment in the next couple of months and feel compelled to do what we can to bump the internal temperature up a few degrees on those odd frosty nights...

Some concerns:
- Proximity of barrel and/or burn chamber to corner pole (which could be cobbed over or ___ to protect it) and/or walls with embedded poles
- Possibility of running flue out wall and, if so, feasibility with embedded poles
- Potential for a less mass or even mass-less heating system.
- Oh yes, it'd be great if the flue was not rising out of our "garden shed" (ie, home) like a red flag for noisy neighbors, passersby to easily conclude that it isn't actually an out-building.
