VIDEO: Compost Heat Recovery Webinar with Gaelan Brown


Join Living Web Farms and Gaelen Brown, author of “The Compost-Powered Water Heater” for hosting our first webinar on the exciting topic of developing innovative heat recovery compost systems. Learn about a totally energy efficient way to grow more food and build great soils at the same time.

  1. I have a question about negative air flow composing. The question is asked in your video about inches of water column relative to cfm. We have built a system but have been unable to find information about the proper inches of water column. Could you supply this information please? Thank you for your time.

  2. I'm confused: you say compost needs to have a fan to avoid the oder, but then you say that you just fan it to a room with wood chips to absorb the smell.

    Couldn't I just add more woodchips to the pile to eliminate the stench?

    Also, you say that the greenhouse that is attached to the compost pile had an awful oder, but you said he used chicken manure. What if you just composted plants?

  3. Suck air from top down so that no water draw up into the vacuum machine and also draw up the heat. the heated air then enter the botom ground of a green house. Cover the entire ground with charcoal or better activated carbon so that when hot air enter the green house, odor can be filtered. Or let charcoal in a container of the pipe systm as a filter, then the filtered air with methane can be burned at the final stage of the exit.

  4. Bat Guano 8 – Nitrogen for heating up pile ….. Sourced Sumatra…. Tropical Biology? Risky introducing to west Michigan soil biology?

  5. Is it possible to have the biofilter be compost of the same composition and size as the source pile? Then reverse the flow every once in a while to keep the twin piles' moisture balanced (and possibly help to keep the lines clear)? Since the biofilter is basically just a positive-pressure aerated pile?
    Is it necessary to use the Isobar® air-to-water heat exchanger or can one just use a commercially available air-to-air heat exchanger like from an air-source heat pump? This would probably work better at smaller/residential scales since it would also have the air-source heat-pump to compensate for whenever the compost gets too cool to suffice.

  6. Sorry if this is a silly question: does composting release more BTUs/energy because it does not emit any light, unlike combustion ?

    That would seem to me to be a sensible explanation as to why there is more energy ‘available’

  7. Great presentation, very informative. No mentioning of peeing on the compost pile as a source of nitrogen and of course moisture.

    The insulated shed composting set up could instead be a basement under the greenhouse with ventilation to the outside with vent pipes. The heat would rise up to the greenhouse.

  8. Wow , i really enjoyed your video . it addresses a few questions ive had i cant wait to share this with my friend . weve been discussing projects for his 160 acre farm . between this and the bio char video info , i think youve given me a year or two worth of work lol. The information is very appreciated . were just over the vermont border in cold canada so cold winters pose challenges. Thanks again ill be watching this again to be sure to get it all down .Thanks to the channel for the amazing content as well. Take care

  9. Amazing information it's not often I ever listen to a video this long. you have really got my head spinning with this and I will be using some of this information for a project that I'm doing with domed environmental greenhouse
