I know you want to see pics. Later this AM I promise. Anyway, got the Enviro M55 FPI in yesterday. Guys had a heck of a time getting the old gas unit out but they did it. Will be back Fri to install the Empress in the Man Cave. Had the unit on Low all night. Kept the LR/DR/Kit/Loft area (1 big area w/tall ceilings) at 69-70 all night. Upstairs bedroom off of the loft with windows open stayed at 68. Bit warmer than I like for the BR but acceptable. It is gonna be a learning curve for sure but so far 1 night down and very happy.
