Good Morning Associates,

I am in the construction phase of my Compost Water Heater and wanted to ask for feedback regarding my project.

Any suggestions are welcome.

So far I still need to design the Temperature Measurement System and Oxygen System to promote bacteria growth.

Would like remote wireless temperature gauges: submersible for water tank temps, and outdoor rated for Compost Temperature Readings. 

Already there is a design change, "Perforated Pipe" running under bottom of water tank to help bacteria grow. Did a Composting Webinar today and found out about how composting works.

Note : Center blocks under 4' side of water tank, not the 3' x 3' side.
Drawings need to be updated.

Thanks for any feedback,

Jack

I have also been thinking about this.  Most of them seem to use coil pipes.

Here is a collection of interesting videos about it.

Good Morning Bert,

Thanks for the info, good stuff you shared with me. I followed your link to youtube and hope to capture that free heat you showed us in your video.

It also does impress me,  the design / layout of a outdoor composting area around buildings. Compost energy as an insulator /heater is a very interesting design concept.

Definitive inspires me to continue on my quest. Cool temperature sensing gun you are using: any info on the Maker, Model, and Cost?
If you care to share that would be an excellent tool to help me with my project.

I too have only seen coil compost heaters, but want more water capacity. The coils seem to limit the capacity of the heater, more coils, larger compost pile = more hot water... I want to heat / warm water to my Jacuzzi and also pre-heat water for my RV.

Hence, the holding tank design. Sense heat rises I am looking to do an output at the top of tank and input at the bottom. I am expecting the heat to travel from Hot Compost through and to the cold water source. After watching Tom's webinar I will be adding a Oxygen intake to the bottom of the pile. This effect / controls microbial bacteria that thrive and actually do the composting of materials. Design change to the original drawings. Will red line drawing in the near future.

And by design the output would / should be closer to the center of my compost pile. I am expecting higher temperatures at core of the compost pile.

I've added some pre-construction pictures on my reply

Also, yesterday did a webinar with Tom Bartels at http://growfoodwell.com/workshops/. I did the one on Composting. The webinar is not a waste of time, Tom gets into the science of how composting works but keeps it simple. Tom did reply back to my questions with links to wireless temperature gauges that you might find interesting.

With the area I saw in your video you might want the ability to monitor temperatures via a wireless sensors around your site. He responded with a couple of useful links to where I can get those products.

I plan on being able to monitor temps around my site, so I am sharing those links with you:

Another source for kit including 10ft sensor wire from Home Depot:

Here’s one that comes with the necessary wired probe:

Thanks again for the reply, have a fine day,

Jack

Sorry, that's not me in the video. That's a collection of compost heat videos I thought were interesting. I would like to eventually experiment with compost heat.

I like your idea of the water tank in the middle of the compost. Lest steps. If you go that route I would be interested in how it works.

They sell temperature guns all over like the big box stores and Amazon.  Also I've seen the long probe compost thermometers on Amazon.

Jack,

Enter "non contact IR thermometer" into google search. I got mine at O'Reilly auto years ago.

Thank you for the reply Gordy.

There is so much info on the internet and finding it with keywords definitely helps.

With all the options that I have found myself, having your reply increases my odds to finding the product I really want to use.

Have a fine day,

Jack

Jack,

Glad you found it useful, and yep that proper keyword thing can be a bugger at times ;-)

I should have added that "non contact IR thermometer" vary in there temp range they will read. Mine is 0 to 525F, which is fine for most of what I need it to do.  I think most of the cheaper ones will be in that range, but there are ones that will read much higher and higher $$$ for those that need to check catalytic converters and other high temp things.

I'm a bit late to this dance but here's the to the BuildItSolar section on 'Heating with Compost '
