this is my first post and pellet stove/furnace. its the farenheit furnace and in definitely happy with it but i feel like i should get more out of it. i know from researching and experiencing, pellet brands make a big difference in heat. so far turmans work best for me. the furnace is my only heat source. it is in the small basement ducted to five vents in 2/3's of a 1500sq ft ranch house. the other 3rd is closed off for now. i have it on t-stat mode and depending on the temp outside for the most part it is on level 4 keeping the house at 73. over 40 deg i can put it to level 3. if i use manual mode will it just keep blowing heat non stop into the house? maybe even put it at a lower level on manual? the house is not well insulated and i don't have an OAK. anyone using this furnace with some tips would be greatly appreciated.
