Karl Schwingel, Owner - Sustainable Heating Solutions



Sustainable Heating Solutions (SHS) was formed to offer Wisconsin residents the ability to use locally available resources for their heating needs as a way to offset use of imported energy sources. SHS wants to help keep our friends, neighbors, and family members working in the woods and heating their spaces with more sustainable, local options. 

For nearly 20 years, my work in renewables has enabled me to gain expertise in a variety of sustainable systems applications, ranging from solar heating and electric, to wind energy, and sustainable heating. Along the way, I discovered a passion for sustainable heating using locally sourced options and began to research and develop how best to apply these applications in Wisconsin. This passion has led to over 10 years of experience designing and installing boiler systems in a variety of applications. My work has ranged from small-scale residential applications to large-scale commercial solutions. 

The sustainable heating solutions made possible through wood and biomass heating options are exciting! I'm happy to be able to offer my skills to help clients use clean, low-carbon heating solutions in Wisconsin.
