This year will be my first season heating with pellets. In talking with others who've been heating with pellets I have heard many different opinions with regard to whether or not the specific pellets used make a difference. Some say it does, some say it doesn't. Some swear by this brand, others by that brand. What do you guys think? Does it matter and if you have experience with different brands could you please share? I'm in NH and the two dominant brands here seem to be the New England and the Vermont brands. Thanks guys.
