I just finished installing a new outdoor boiler today and will fire it up in the morning. It is a Dual Force 5K made by Outdoor Boiler Manufacturing Co. in Greenwood Wiconsin. Because they are new in the industry with only a year of Mfg. history I have not been able to talk to any other owners. I started this thread so I can keep everyone updated on how it performs,its pros and cons, and whether I will recommend one to someone else. A friend of mine bought one at the same time and is installing this week also so there will be two units to compare.
