Heating a home with a compost heater?  RSS feed

I heard that Jean Pain put together a compost heater that could be used very effectively with bark dust to warm homes and offices. Does anyone have any further information on the details of building such a device or has it been compiled into a comprehensive guide?

I don't think there is a comprehensive guide anywhere, but the topic has been discussed here on the forums quite a bit, so you might find some useful info there. I know also that Paul is doing some experiments at his place to see how to heat water using compost, but the results have been hit and miss: http://www.permies.com/t/28737/pp/hot-water-compost-pile

There is kinda... not comprehensive "guide" per say... but it is an extensive study of heating a greenhouse this way in Massachusetts.

here you go:

It seems as though there are a number of people who get started, but don't really finish showing or explaining the outcome. It sure would be nice to see a solid setup of this in action and the material it takes to do it.

Well it's not the data that concerns me. It seems certain to be an amazing solution that kills multiple birds with a single stone so to speak. The only problem I see are some folks talk about how they're building it, but then don't show the results. For example, does the water circulate upwards from the heat as some seem to assume without sharing their results? And what have people seen to maximize utilization for a home heating system? It seems you would have to flow the water from the compost pile or piles and then through some insulated piping to a radiator of sorts that is attached to the heating system for a home. Or can you also use a mass (passing the hot water through the mass en route to the blower) prior to passing the water on into the hot water tank for circulation on into the bathrooms? My goal is to not have to retool my devices entirely, but to cost efficiently replace parts as possible initially and then go from there.
