Glenwood Boilers are simple yet robust, clean burning but not complicated, efficient but not expensive. It is not a batch burner, does not require water storage, does not use Lambda sensors or computers to operate and instead works on a simple map program that is not overly complicated. What Glenwood is doing is tremendously valuable and best of all, it’s American innovation, born in the Anabaptist heartland near Lancaster, PA. Their boilers range in size from 100,000 to 1 million BTUs, with custom units available as well. You can check out more boilers from Glenwood on Obadiah’s Woodstoves, like the 7070 Multi-Fuel Boiler, here.
