Thanks for the tip Chip! The only reason I would want to be heating the floor with Bio-diesel instead of water or Glycol heated by solar and/or a wood fired boiler, is because I have to dry the fuel anyways. I'd rather not waste that energy so to speak so I may as well pump the fuel throough the floor while I'm heating it and heat the building... When I need to heat the next batch, my thought was to have a hopper above the heating system which is allways full and I would recharge the system with exactly the amount I remove..
Eventually I'd love to run the system on solar or another renewable heat source...

Second law of thermodynamics. While an oil burner is in the same order of magnitude as the work in this case, heating the floor, it's still a higher quality of energy. A closer match is solar power. The closer the match, the more efficient, taking the long view. esp when you factor in the cracking of the biofuel in the first place. Biofuels, like fossilfuels are just too danged convenient for their own good. :) Using your ingenuity and some more of your food powered energy (IE doing work) you could probably front load your heating needs by dreaming up and implementing a solar heat collection/distribution system, which would drop the biofuel requirements for your heating needs radically. I know you are trying to get this done on a short timeline, but please plan for migrating the main energy source from the oil burner to solar collection, I think you'll be happy you did. You don't have time to do it this year, but maybe next summer. Again, neat project, keep us posted! cheers --chipper ----- Original Message ----- From: "Chip Mefford" <[EMAIL PROTECTED]> To: sustainablelorgbiofuel@sustainablelists.org Sent: Tuesday, October 26, 2010 6:06:16 AM Subject: Re: [Biofuel] Nigeria: Shell Oil's 'License to Kill' ----- Original Message ----- From: "Seth Macdonald" <[EMAIL PROTECTED]> To: sustainablelorgbiofuel@sustainablelists.org Sent: Monday, October 25, 2010 11:11:35 PM Subject: Re: [Biofuel] Nigeria: Shell Oil's 'License to Kill' |SNIP |I am also madly trying to pour a floor in my shop complete with in-floor heating |pipes before freeze-up(which is happening SOON!) | |I am curious if anyone out there has ever tried to run Bio-Diesel in a hydronic |in-floor heating system.

This system uses an oil burner converted to run biodiesel. It works. This system is installed at the Dickenson College Farm CSA, which grows the food for Dickenson College in Carlisle Pa, US. This is the website: http://www.dickinson.edu/about/sustainability/college-farm/ Jen Halpin is the farmer/farm manager, and her partner, Matt is the whacko who comes up with stuff like this. You can find her contact info on the website, and they may be able to share some clues with you. Good luck! Sounds like a fun project. _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/sustainablelorgbiofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (70,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/ -------------- next part -------------- An HTML attachment was scrubbed...
