Certainly sounds noisier than an electric tank Hard to tell from the video if the noise level would be noticable in a closet right off the living room. I need to find someone in my area (good luck) that has had one installed. Out local gas company has been promoting them each month with a flier in with the bill. Someone will get one sooner or later. Noise would be a killer for my household, not me as my wife says I am deaf but for my wife acceptance factor.
