I only have the P43 (house is 900sq/ft) but compared to my out of date Baron its quiet, almost too quiet because I have to check on it that its still running. My only complaint is that I can't get the heat moving around the house, can't find any blade fans in the stores right now. Living room install is what I wish I had done. I have the stove in my computer room and on my Mac I only have it at 4 bars and can hear it fine vs the stove fan on high.
