The following series of posts provides lessons learned from a 2 week Permaculture Design Course in Chiang Mai, Thailand. By taking very simple steps, we can  all take control over simple technologies and free resources to simplify our lives.

Compost Hot Water Heating

There is a simple way to harness free energy from living organisms. The simple process of composting food scraps and yard waste uses microbes to break down organic matter into rich soil. The byproduct of this reaction is heat.

By following a simple method, you can capture the heat and use it to heat water. This water can be used in hydronic heating systems, or provide hot water for showers.

Step 1: Gather composting material consisting of:
- 50% brown matter such as straw, hay, leaves, etc.
- 50% green matter such as weeds and food scraps or high nitrogen content material such as cow manure

Step 2: Lay a layer of sticks on the ground to support the compost pile and allow for free airflow beneath the pile

Step 3: Provide a layer of brown matter a couple inches thick and water the pile. Then provide a layer of green matter a couple inches thick and water the pile
