Costs and Benefits of Solar Thermal and Wood Boiler Combination Systems
This study will quantify the costs and benefits of combining solar thermal systems with wood boilers to offset wood consumption and reduce pollution. Both flat plate and evacuated tube systems will be examined for their impact in the cold climate of Minnesota. This project represents a priority area selected by the Central Minnesota region during the 2013 Clean Energy Resource Teams statewide conference, as well as a priority of the Energy Work Group of the University of Minnesota Central Region Sustainable Development Partnership.
The Central Region Clean Energy Resource Team (CERTs) will help with the education phase of the project and dissemination of the research findings. CERTs will feature the findings through their regional gatherings. Additionally, RREAL will present the findings at the next Statewide CERTs conference where energy advocates from around the state gather to learn about the community-University project partnership.
