We just had one installed after having had it on order for months. Verdict is out for me. It is quite noisy -- if you run it at high, which you need to do to get heat, it really is noisy but it is in the room we want to spend most of our time in so that is a pain. And it periodically, (often) releases little charges of pellets to burn which make a wierd noise. Someone at work who has one and figured I had to love it asked my opinion -- I stated the above -- he said get a life! Good point but I really do hate background noise that is intrusive......wondering what other people's views are?
