Hello, I'm looking for a nice free standing pellet stove for my sunroom which is around 500 sqft. I heat our house with the hampton wood insert but we usually close the sunroom-too cold. We have an electric heater but it sucks and I'd like the sunroom to stay 73 or above. Also looking at the thelin which seems to have a lot of negative feedback and the pipe is off center which would drive me crazy. Also, the Upland 207 has great reviews with no owners to talk to. So the Castile looks to be my best option. I don't mind cleaning but how is the noise with this unit? I have read it can be noisy. Any feedback regarding this stove is much appreciated. I have two or three shops around my area that sale this stove so I will be looking to deal. Sunroom mostly glass with the foam type roof. Shop said venting is no problem through the roof.
