This is my buddy Matts shop. We built this huge shop and made a simple tank in tank home made wood boiler. He is heating this shop with less than 8 face cords of wood a year. We live in central New York real close to Lake Ontario. We get tons of snow and cold temps. There are many reasons this system works so well but it all starts at the foundation. Super insulation details and thermal mass makes for a comfortable structure. If you have any questions on how we put any of this together be sure to ask.
