Hi I am new and just researching my systems before I put them in. I plan on eventually having at least one large greenhouse full of aquaponics. I Live in Virginia and where as it doesn’t get too cold…Continue

Hey WD, have you done compost heaters before? I built an in vessel 20' long high rate rotating composter some years ago and although it would hit 180F by about day 3 it would rapidly decline in temp over the next 2 weeks. If not for the fact that I added new finally ground and well formulated (carbon to nitrogen ratio) organics every couple of days the heat would be useless for heating any real space. I also found that it took very hot nitrogen like fresh chicken manure or fish heads and guts from a fish store nearby.It made fantastic compost on a continuous basis but I doubt it would account for much heat and it takes fresh batches to make that heat. I do plan to make a new one using plastic 55g drums for our GH soon. You can see it here in my plan. That and the hot tub are the only 2 items left to make.

yes Jim the compost heat water flows through the lines to and from radiator. Awesome build on your stoves.

here is a link to more detailed pics and a couple videos showing this system so far.

OOOH, nice radiator Wild Dog. We heat with wood here and I am always looking for old radiators, lol. I assume that is the compost heat system. My gasification GH wood stove is doing amazing and now we have been heating our house with my latest design for 3 seasons.

I have been invited to build a off grid AP system by T.U.R.F. (The Urban Renewal Farm). The 1st week of December I started the build. I started with Solar power and  compost heat. I now have baby Koi and Gold Fish in the 110 gallon tank, and I have the floating raft grow bed planted with spinach, lettuce, and mustard greens. even have a Kale and Mint in it.

hey Jim, I also sell gasifiers. I am still working on my website but you can check out the ones I'm selling at; www.stakproperties,com  they also have some good movies on how they run and how to use them.  hope this was helpful! Terry

Hey Jon, still waiting for that info on your gasifier. You're not really asking us to fly to the west coast to find out more are you?? Been 2 yrs since you promised pics and a diagram

My latest gasifier wood "boiler" (not) will be getting a first burn in this week. Whole new concept that has been awhile in the making and this one is for the house via radiators. Pics soon as it only just got turned right side up for final welding this week. The GH heater version has been a great success and going into it's 3rd Winter now. Got us thru 20F below last Winter.

Come on over and join West Coast Tilapia.  We look forward to your input!

Jon, I'm a year or two from getting out to your place but looking forward to it.  I agree agree about biomass.  We treat it mostly as waste but it's quite a resource.

George, Bill, Debra and All. I use wood gasification for heat and electricity, and CO2 boost for plant growth booster and pest control. Wood gasification and biomass is the key ingredient to sustainable life. It is really very easy, and I made a gasifier from a beer keg and scraps from the shop. 

I teach a 5-day aquaponics class, incorporating greenhouse design, wood gasification, rocket stoves, bio-char, CO2 pest control, climate battery (geothermal heating and cooling), pumpless aquaponics, BSFL, worms, aerobic and anaerobic microbial brews, fish breeding, chickens and rabbits, home-made fish and livestock feed, air-lift pumps, solar, and more. Next class is April 29-May 3
