I am considering the enviro M55 FPI, I have a masonry fireplace, 3400 sf new home, open floor plan with duct system that I can run the fan to circulate the heat from the M55. First will it heat my house, or is there a bigger btu insert on the market. I was also considering the Pacific Energy Summit insert, but think I want to go with the pellets. If the M55 can't heat my house, I could close some registers in rooms we don't use much. Also was considering a small lp gas fireplace in the master bedroom, wife would really like one, and it would help with the heat load. All thoughts would be appreciated.
