Hello I currently have a Johnson outdoor wood boiler that has been used since 2001. I have been thinking of installing a new gasification outdoor wood boiler, outdoor pellet boiler, or indoor pellet boiler. My house was built in 2000 and has 2100 sq ft with baseboard hot water, 2100 sq ft basement with radiant in floor, and attached garage with 576 sq ft radiant in floor (5000 total sq ft). inside i have a viessmann propane boiler from year 2000. . Any suggestions? thank you for your time!
