hi R Ranson!
sorry about so little information. i am no good for long mails but i'll try to be a little more precise about this one.
i live in senegal right now where i'm running with my wife a little permaculture project (gorom-garden.over-blog.com)and i will stay here till begining of december then move to normandy (france) where i originally come. from. so for the details concerning the house i can't give all the answers but i'll do my best...for more details i'll have to wait till i get there in december.
How big is the space? approximately 75/80 m2
Will you be heating all the rooms at once, or just some of them as needed? i'm hoping to heat the all place with the RMH and i still need to research about air flow/ natural draft
How much draft? no ideas yet
What's the insulation like? the wall is builded with local stones, i don't know about the roof insulation. the house is oriented west/south west and we'll be puting a big window for natural sun light/heat
What's the insulation going to be like when you finish the upgrades? there we'll be an earth floor that'll help a lot and for the roof i still have to see before i get into speculation...
I've noticed at least one home (ahem, mine) where we installed the heating system first, then found it too hot once the other upgrades were complete. this is exactly the reason why i've posted in the first place. i was thinking of using the RMH for heat and adding a cast iron stove for cooking but i'm pretty sure the heat will be too much... this is why i need some kind of maths formula to work with
Is there sufficient airflow without being drafty? sorry but i'm not natural english speaking and i don't understand the question
Will you use some sort of fan to move the heat arround? nope
How damp is your winter? Damp makes things feel colder than they are. Here, zero C feels SUPER COLD, but back east, -20 C is merely cool the house is about 2/3 high up a little hill facing south (the hill not the house) with a little river approx 100m down the bottom of the valley. the winter is very wet and doesn't often go below zero c° but the wind can be pretty strong. we are approx 70 km from the sea. being a farmer/landscape desinger for quite few years i can tell you for sure that it feels very cold and wet in winter...but the common normand house do well in wet climate...
What fuel will you have access to? Hard wood? Soft? Something else? hard and soft woods. (i aint' to sure what you mean? do you mean wet or dry?)
If you feel comfortable, can you give us an idea of what part of the world you are moving to? Different places have very different ideas of winter. koppen climate zone Cfb altitude: approx 100m distance from the sea: approx 70 km
Will you be cooking with the same system you heat with? nope
hope you get the detailed you were looking for... i'll definitley let you know about the progress i'll be making as for most of the work i'll be doing it'll be the first time to do it for me, so i'll need technical advices over more or less every work i'll get involved in...
thank you for your help
