I bought it http://shop.ebay.com/?_from=R40&_trk...All-Categories
on eBay probably two years ago from an outfit out of Phoenix. I would've thought I could go to paypal or eBay to recover that information, but I guess that goes too far back because I couldn't find it. So the link to tankless water heaters on eBay today, that I just posted above is how I found the one I have. If I remember correctly it's around 12. liters per minute for the rate of flow and the temperature increase above ambient is something I'm going to have to go by feel and hopefully it will feel warm enough for a shower. Since the water tank that supplies the shower will be inside under the bed, it will be somewhat insulated itself. I don't really have a firm plan A. because I felt that would restrict my possibilities, potential to use the materials that I found in my environment at any given time. Of course I travel a lot so I have a lot of possibilities and can follow a good lead. Oh ya the money - I think it was just under or over 300 dollars, most of the LP tankless water heaters at Home Depot or Lowes were in the 500 to 1000 or more.
