Cob: terra cotta pipesphil phawn1 at excite.comWed Jan 29 08:57:15 CST 2003
I haven't researched the idea further than thinking it would work. I believe that pipe comes in six inch diameters. Tha floor would be eight inch terra cotta tiles in a bed of sand six to ten inches thick under which is a base of gravel. There would also be a cob wall (kitchen counter) at the edge of the floor area within the suns reach that could also transfer heat to a pipe system. Still in the early planning stages. I have three more books on passive solar to read.

My plan is to make the main passive solar living space about two feet lower than the back portions of the house and use terra cotta pipes running from under the heated floor up to the back rooms. In the summer you could easily block off the openings or provide shade for the solar heated area. There would be no need for any kind of circulating fan. <DIV></div> <DIV></div>> <DIV></div> <DIV></div>>By the way, here in the mountains of NC it got down to -3 at our house last Friday. We are planning very carefully for these kinds of temps in our cob home. <DIV></div> <DIV></div>> <DIV></div> <DIV></div>>Phil Hawn <DIV></div> <DIV></div>> <DIV></div> <DIV></div>> <DIV></div> <DIV></div>> <DIV></div> <DIV></div>> <DIV></div> <DIV></div>> --- On Mon 01/27, mcleod lindsay < lindsaymcleod at yahoo.ca > wrote: <DIV></div> <DIV></div>>From: mcleod lindsay [mailto: lindsaymcleod at yahoo.ca] <DIV></div> <DIV></div>>To: writejill at hotmail.com, coblist at deatech.com <DIV></div> <DIV></div>>Date: Mon, 27 Jan 2003 09:49:28 -0500 (EST) <DIV></div> <DIV></div>>Subject: Re: Cob: <DIV></div> <DIV></div>> <DIV></div> <DIV></div>> <DIV></div> <P> <DIV></div> <DIV></div>> <DIV></div> <P>I am by no means an expert on this topic but I remeber when I first started reading about cob something talking about heating ducts in the floors allowing the heat to move from one room to the next. So I am not sure if there is a way to funnel the heat through these ducts to heat your other rooms. I remeber it also talking about how some people built cob beds and the ducts were in the beds (an alternative to a heating blanket). This is just a thought to consider.
