So I was a little apprehensive last night to go to bed with the stove running but after reading many posts on here saying it was okay and being reassured by the installer. I programmed the thermostat and went to sleep. I have to say I slept like a warm baby! The stove is in the living room which was about 75 degress and the bedrooms are upstairs and it was 73 degress! I think it was about 10 degrees outside this morning so I could not be more happy. I am sure I may have to play around with the programmed settings to get it where I would like it. I topped off the pellets this morning and left for work - wishing I could work from home in my nice warm and cozy house.
