In a quiet corner of a small German village, a cloud of steam rises silently from a nondescript shed behind an ordinary house. No rumbling boilers, no hissing pipes – just the peaceful sight of hot water being produced, day in and day out, without a single drop of oil, gas or electricity.
This is the domain of Joachim Goeres, a self-described “tinkerer” who has spent decades perfecting a low-tech hot water system that puts modern, high-tech heating to shame. His backyard plant produces a staggering 3,000 liters of hot water every single day, all while costing him virtually nothing.
Goeres’ story is a testament to the power of innovation, perseverance and a determination to find alternatives to the energy-guzzling status quo. It’s a quiet revolution happening in backyards around the world, one that could transform the way we think about heating our homes and businesses.

Shedding the Shackles of Electricity, Oil and Gas
For Goeres, the journey to his hot water wonderland began decades ago, when he grew increasingly frustrated with the cost and environmental impact of traditional heating systems. “I was tired of watching my money go up in smoke every time I turned on the boiler,” he recalls. “There had to be a better way.”
Drawing on his background in engineering and a healthy dose of curiosity, Goeres set out to design a system that could provide abundant hot water without relying on fossil fuels or the electrical grid. The result is a remarkably simple setup that harnesses the power of natural resources and human ingenuity.
At the heart of Goeres’ system is a series of large, custom-built water tanks, strategically positioned to capture the heat from a nearby compost pile. As the organic matter decomposes, it generates a constant supply of thermal energy, which is then used to heat the water in the tanks.

The Magic of Compost and Thermal Dynamics
The process is elegantly simple, yet remarkably effective. As the compost pile generates heat, the water in the tanks absorbs it, gradually warming up to temperatures of up to 80 degrees Celsius (176 degrees Fahrenheit). This hot water is then piped into Goeres’ home and a nearby greenhouse, providing ample heating and hot water for his family and his small-scale agricultural endeavors.
But Goeres’ system is more than just a clever way to harness the power of decomposition. It’s also a masterclass in thermal dynamics and energy efficiency. By strategically positioning the water tanks and insulating them carefully, he’s able to minimize heat loss and maximize the amount of usable energy that can be extracted from the compost pile.
The result is a self-sustaining system that produces an astounding 3,000 liters of hot water every single day, all without the need for a single kilowatt of electricity or a drop of fossil fuel. “It’s the ultimate in low-tech, high-impact technology,” Goeres says with a proud smile.

Revolutionizing Heating, One Backyard at a Time
Goeres’ hot water plant is more than just a personal triumph – it’s a model for a new way of thinking about energy and sustainability. By demonstrating the power of simple, nature-based solutions, he’s inspiring a growing number of people to rethink their approach to heating and hot water.
In a world increasingly grappling with the challenges of climate change and the rising cost of energy, Goeres’ system offers a compelling alternative. “It’s not just about saving money,” he explains. “It’s about taking control of our energy needs and finding more sustainable, eco-friendly ways to power our lives.”
And the impact of his work is already being felt. Goeres has become a sought-after expert, sharing his knowledge and expertise with homeowners, businesses and policymakers who are eager to replicate his success. His backyard plant has become a testament to the power of innovation and a symbol of a future where clean, affordable heating is within reach of everyone.

Tinkering with a Purpose: Goeres’ Passion for Problem-Solving
For Goeres, the journey to his hot water plant has been one of relentless experimentation and problem-solving. “I’ve always been a tinkerer at heart,” he says. “I love taking things apart, figuring out how they work, and then trying to make them better.”
This passion for innovation has driven Goeres to constantly refine and improve his system, always seeking ways to make it more efficient, more cost-effective and more accessible to the average homeowner. From adjusting the size and placement of the water tanks to experimenting with different types of insulation, he’s constantly fine-tuning his creation to push the boundaries of what’s possible.
But Goeres’ work is about more than just personal satisfaction. He’s driven by a deep-seated belief that small-scale, low-tech solutions have the power to transform the way we approach energy and sustainability. “I want to show people that you don’t need to rely on expensive, high-tech systems to heat your home or your business,” he says. “With a little bit of creativity and a lot of determination, you can build something that’s just as effective – if not more so – and at a fraction of the cost.”

The Future of Heating is Homegrown
As the world grapples with the realities of climate change and the rising cost of energy, Goeres’ backyard hot water plant is a powerful reminder that the solutions we need may be closer than we think. By tapping into the natural processes that surround us and harnessing the power of human ingenuity, he’s paving the way for a new era of sustainable, affordable heating.
And the impact of his work is already being felt. As more people discover Goeres’ system and the benefits it offers, a growing number of homeowners, businesses and policymakers are exploring ways to replicate his success. From small-scale greenhouses to large commercial buildings, the potential applications of his technology are endless.
For Goeres, the future is clear: the days of relying on electricity, oil and gas are numbered. In their place, a new era of homegrown, low-tech solutions is emerging – one that puts the power of heating and hot water back into the hands of the people. And with pioneers like Goeres leading the way, the possibilities are endless.
