Harnessing Free Hot Water from Compost: The Wheelie Bin Compost Heater

In the quest for sustainable and eco-friendly solutions, innovative thinkers have come up with various ways to tap into nature’s resources. One such ingenious idea is the Compost Wheelie Bin Hot Water System, a concept that allows individuals to generate free hot water using compost. This low-cost, easy-to-build system can produce water temperatures comparable to conventional hot water systems. In this article, we explore the details of this innovative system and how it can be easily implemented by anyone.

The Compost Wheelie Bin Hot Water System

The Compost Wheelie Bin Hot Water System was introduced by Daryl, a member of the Aquaponics Made Easy Forum, and has since gained popularity for its simplicity and effectiveness. The system essentially consists of a compost heater inside a wheelie bin with coiled poly pipes along its outer wall. These pipes, which extend approximately 8 meters within each bin, serve as a conduit for water circulation.

How It Works

Compost, a mixture of green nitrogen-rich materials and carbon-rich materials, undergoes a natural decomposition process, releasing heat in the process. In the Compost Wheelie Bin Hot Water System, the compost reaches temperatures of up to 70 degrees Celsius, comparable to the thermostat settings of conventional hot water systems. This high-temperature compost acts as the heat source for the system.

The implementation of the system is straightforward. The first wheelie bin is loaded with a mixture of grass clippings and horse manure, providing the essential nitrogen and carbon components. After two weeks, the second wheelie bin is loaded with the same mixture. Then, after four weeks, the first bin is emptied and reloaded. While the system can be left running for longer periods, the primary heat production occurs during the initial four weeks of compost decomposition.

Advantages of the Compost Wheelie Bin Hot Water System

  1. Cost-Effective: The materials required to set up the system are readily available and relatively inexpensive. The wheelie bin, a commonly found item in urban areas, can be easily sourced.
  2. Renewable Energy Source: Unlike traditional hot water systems that rely on electricity or gas, the Compost Wheelie Bin Hot Water System taps into the renewable energy produced during the composting process.
  3. Environmentally Friendly: Composting is an eco-friendly waste management technique that reduces landfill waste while producing beneficial byproducts like nutrient-rich soil.
  4. Versatility: The system’s adaptability makes it suitable for various settings, including households, community gardens, and small-scale agricultural setups.
  5. Energy Savings: By utilizing compost-generated heat, users can reduce their reliance on conventional heating methods, leading to potential energy cost savings.

Considerations and Precautions

While the Compost Wheelie Bin Hot Water System is an innovative and efficient way to generate free hot water, several considerations and precautions should be taken into account:

  1. Safety: As with any system that involves heat, proper safety measures must be in place to prevent accidents or injuries.
  2. Insulation: Adequate insulation of the hot water pipes will help retain heat and improve system efficiency.
  3. Compost Maintenance: Regularly turning and aerating the compost will ensure optimal heat generation.
  4. Scale: While this system is suitable for individual households, it may not be sufficient for large-scale applications.


The Compost Wheelie Bin Hot Water System exemplifies the brilliance of harnessing nature’s processes to meet human needs sustainably. By capitalizing on compost’s ability to produce heat, individuals can enjoy free hot water, reducing their environmental impact and energy costs. With simple materials and easy-to-follow steps, this system is accessible to everyone willing to explore a greener and more sustainable approach to heating water. So, why not turn your kitchen and garden waste into a renewable energy resource with the Compost Wheelie Bin Hot Water System?
