I'm in the process of building a smallish 6" system with about 10' of buried flue for the mass. I have a quick question for you guys. I have a lot of magnetite bricks in the barn. They came out of our big electric storage heater we dismantled two years ago. From what I understand magnetite is pretty good at storing a lot of heat. The thing I'm unsure about is how fast will it release it. I understand that monolithic cob would release its accumulated heat at about 1 inch per hour. Does anyone know how fast magnetite loses its heat?
Depending on the answer I would use more or less of the magnetite.
Dominic Leomoine : Goggle the 'engineers tool box' and then try for an answer in there, I would not actually worry about it to much, as a good general rule heavy means will hold
lots of heat and within reason follows that up with fairly fast radiation !

Thanks for your comment. I'll use the lot!
So how big is your travelling yurt? We've got 20 footers here. Plenty of space!
Ive just being trying to search and find information on using the bricks from old electric storage heaters but the terms are so diffuse a lot of stuff comes up.
How did you get on? Im also just about to build a mass and am wondering what to fill it with for basically nothing.
Where in Wales are you? Im up North if youre close and want a look at mine?
