The purpose of this site is to chronicle and share experience in developing a residential energy management system. This project started out as the simple addition of a wood boiler, but quickly grew into the design of a multisource (wood/oil/solar/heat storage) heating system. A major part of the project was the development of control system hardware and software to manage energy across all subsystems. This control system became known as the 'NoFossil Control System' (NFCS) which has been used all across the northern United States and Canada. It has now been relaunched as a commercial product by Vermont Energy Control Systems LLC - the Vesta controller.
The hope is that this site will evolve into a helpful resource for others who are undertaking similar projects. Welcome, and please feel free to contribute, ask questions, or just poke around. You may contact us by email at .
This site espouses no particular social or political agenda, other than a belief in the idea that it's good for people to be able to take control of meeting their own needs.
The focus is practical solutions to design and management of energy for residential space and water heating. The information here is based on our needs and experience, and may not represent the best approach in this or any other situation. This site is not intended to replace the advice of professionals. In particular, code and insurance requirements vary by locale.
The original system documented here consists of an Orlan EKO 25 wood gasification boiler, a heat storage tank, a traditional oil boiler, solar hot water panels, an indirect domestic hot water tank, a hot tub, and a home-brewed controller.
