Hey guys. Got my wittus ego stove cleaned last Monday by the dealer. I specifically did not tell him which pellets I used so he would not be biased evaluating my pellet choice. His first words were " wow whatever pellet you used worked real well with this stove. It's really clean. Seems like this stove is pretty efficient." Now im taking him for his word. I burned a variety of box store pellets (mwp, green supreme, stove chow, and a few green team bags). So my assumption is that my stove did not mind the cheaper box store pellets and kept the house nice and warm. It only needed a vacuum once a week and cleaning that took 10 mins. I just recently purchased 5 tons of green supreme for 188 a ton. I will only use between 3.5-4 tons but you never know what the price will be next year The wittus ego was definitely a great choice for me. It easily heats my upstairs approximately 1500 sq ft and increased the temp in the house from 62 to 72 in 1 hour. It is also super modern and I've had a million compliments on it. Some cool features coming up hooking to wifi in order to send a text to it to turn on ( just hoping the chip comes into production in the us this year). It also added a beautiful looking fire at night.
