wiscojames: Donkey is elbow deep in cob, Peter is prototyping a new heater core and Matt is cooking a lamb shank on the tiny cook stove. Jan 24, 2018 9:57:21 GMT -8
matthewwalker: My title says moderator, but I don't think I have any powers here. If I do, I have no idea how to do anything. My screen looks just like a regular user, no special moderator tools. Jan 25, 2018 20:25:28 GMT -8
vortex: An honorary member them Matt ;) Someone needs to do something. May I suggest: support.proboards.com/thread/567516/limit-post-new-members Jan 29, 2018 2:26:23 GMT -8
peterberg: Catching spammers is work, as well as reviewing every new registration. My powers are sufficient to hunting and deleting spam, but fall short to do what Trevor suggest. But I am getting quicker by the day, the last one was banned before he could post. Feb 3, 2018 13:34:32 GMT -8

dan1941300: Hi, I want to build nearly the same stove like you did a little bigger 1 brick every side more to put 10 cm Isolation more in inside. Please could you measure up all sizes also from the hot water tank (maybe you know how many liters the tank has) thx May 11, 2018 9:13:45 GMT -8
dan1941300: If possible in metric cm, how many Celsius at the chimney? Is there anything you would do different if building again? Sorry for my bad english, my language is german, austrian. thx a lot May 11, 2018 9:38:02 GMT -8
smarty: Dan my batchbox reached 1150C so refractory cement rated to at least 1200C May 21, 2018 22:53:56 GMT -8
mercedes: Not sure where this question will end up...I just registered. HOW THICK SHOULD PERLITE/VERMICULATE/CLAY INSULATION BE BEHIND THE THERMAL BATTERY/COB BENCH IF IT BACKS UP TO A STRAW BALE WALL? Thanks! Can you please also post me: nathomegal@gmail.com thnx!! May 28, 2018 20:05:23 GMT -8
kkp: Mercedes: Benches don't get real hot. In fact, they are rather cool compared to other areas. You shouldn't need a mix like you described Jun 7, 2018 18:10:52 GMT -8

martinm: any one here with info \ experience with heat (from a mass heater) distribution with ducts throughout two storey house ? Sept 8, 2018 22:58:52 GMT -8
padica: Good morning, this is a wonderful subject, please someone can help me with the theme of double and triple combustion, how it is achieved, theory and design, thank you Sept 15, 2018 7:13:40 GMT -8
wiscojames: I'm afraid you won't get a response to such a vague question - I suggest reading through some of the threads related to your questions before asking for an explanation. People will be very generous with their knowledge if your question is more specific. Sept 18, 2018 4:48:00 GMT -8
drjmf: How do i make this more powerful and efficient ? Need more BTUs up the chimney to heat a 100 litre water jacket around the black flue pipe........ www.youtube.com/watch?v=SKcUXeHose0&feature=youtu.be Oct 2, 2018 3:50:52 GMT -8
daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for Nov 30, 2018 12:48:38 GMT -8
