1st experiments were just off the shelf compost tumbler style composting.
Didn't work well for me.

Smallest Compost heater experiment was small
~4 Gallons in a old ~5 Gallon water bottle , in my basement.

It didn't make enough heat to create a noticable dT from ambient .. but did compost some of the material over a ~6 Months potential heating season.

Then I tried 6 different mixes , each ~40 Gallons in it's own ~55Gallon Drum.
Also in my basement .. exhaust gases vented out through old (not in use) natural gas water heater chimney flue.

Better results , but not good enough.

This 2020 winter I started the 3rd test / experiment outside in back yard ~600Gallon total.

It's been doing better so far than the 2nd test .. but , there are still some improvements I have planned for a 4th version in the fall/winter of 2021.
