4 days and starting on my 5th bag of pellets..here are a few observations....Eastern embers pellets...lots of ash!! I have cleaned my stove 2X (vacuum behind baffles etc) I can't imagine letting it go a week!! I guess about one cup of ash per bag of pellets. takes no more than 10 minutes to clean the stove though. Heat is great...it has been -5 to -10C (14 to 23 F) and stove is set on med (lo med high) furnace has only run to supply hot water. It is a 2 story modern construction with 0pen stairwell. Main living upstairs (1000 sqft) stays between 72 and 68 deg , family room on main floor (600 sqft) on slab where the stove is is also around 72 deg... actually slightly cooler than livingroon at the top of the stairs! Both stove and furnace on programmable thermostats to setback at night.....very pleased!....except today I arrived home to a dead stove....auger barely able to move pellets......so I emptied the hopper and as quad suggests I loosened the feed assembly (2 screws) jiggled it till it was free...re assembled and voila it is working fine again. I hope this is not a recurring feature of my stove!!
