I put the Ed's message and photos on the web site, and you can see the youtube video on the same page. http://stoves.bioenergylists.org/content/welsh-biochar-making

The link to youtube shows the overall layout of Ed's indoor water heater and though the audio is poor he explains how it works. I expect Erin will see if she can upload the images to the website.

They are capable of heating over >200 litres on one 3 hour burn and catch residual heat in a thermal mass without any visible emissions. > > Ed _______________________________________________ Stoves mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page http://lists.bioenergylists.org/mailman/listinfo/stoves_lists.bioenergylists.org for more Biomass Cooking Stoves, News and Information see our web site: http://stoves.bioenergylists.org/
