If humanure handbook compost was in a small building would the building be heated?

I thought I answered this question already last week. Maybe I forgot to hit "post this message."

The heat of the compost is mostly contained inside the pile. It's unlikely that it would heat a building. I have been standing next to massive compost piles at 170F internal heat and never felt any heat emanating from them.

Yes, I guess I should have checked before I answered a second time. I did go and look and sure enough, the question was there twice and so were my answers. So I deleted one of the sets (that's the advantage of being an administrator to a message board).

Two possibilities for large scale compost heat use are for heating domestic water and for growing early vegetables.

For the former, see http://www.rdrop.com/users/krishna/greenhse.htm

They built a large, straw bale hoop house over a big compost pile, ran hoses through it, and got hot water for 18 months.

These people are amazing, and doing all sorts of interesting experiments. They also compost humanure.

For the later, I can't remember the site, but I've heard of using a long row of semi-finished compost piles at low temperatures (around 100 degrees) to plant out early tomatoes and others.

Hi,

We've been "sawdust bucket" composters for a couple of years now. I'm also an eco-home designer (been at it since 1960 - no, that's not a typo in the date) using earth-sheltering, annualized passive solar (A technique I've evolved to very inexpensively heat the house in winter with stored summer solar, in places where winter solar delivery is "unreliable"), use of strawbales, tire-bales, earthbags, etc. in building. And I'm always open to "new" ideas to do the job better/easier/more ecologically. One I'm currently researching is the use of large compost vaults, tapped by water-filled coils, to provide warmth for in-floor radiant heating and recharge. I'm familiar with the "krishna" pages previously cited and the greenhouse heating done in british orangeries using stable waste, and have visited a home in central Washington State which the owner tells me is heated in this way, but would would like to hear from others who have knowlege relevant to this technique, as well. And I will be happy to share what I know on this and related topics...Don Stephens, Eco-Design Consultant and construction innovator (for those wishing to learn more about annualized geo-solar heating, you will find an intro to it posted at www.ecolivingcenter.com/articles/geosolardesign.html ... : )

Wow! That's amazing! So despite what Joe has been saying, it is possible to use heat from compost!!!

The only concern I can think of is that some of the heat of the thermophilic process is lost, and therefore may not get hot enough.

Hi, Regarding heat use from a compost pile, as well as methane tapped from the pile for the posibility of generating electricity, cooking, heating, and running a vehicle on, see the following links about frenchman Jean Pain for a start:

Strange, but that is the way I feel about it, too--except maybe the last use before emptying the bucket! :) Seriously, there is something therapeutic about going so naturally!

All the best,

I would guess that a normal single family compost pile would no be enough to heat much.
I have not really looked into the other experiments yet but am assuming they are more than a 5' by 5' by 5' pile producing the heating.
I expect that a more comercial sized composting activity might be able to produce some surplus heat for other purposes but it will also take a little extra energy to manage.
