Recently I purchased this tankless hot water heater for my home which is about 2400 sq ft. It works pretty good, although it does take several minutes for the hot water to reach most of the rooms. I can say to be prepared for additional cost to install the unit. As many of the other reviews were quite helpful in knowning what to except during the install, it did take a plumber and an electrician to insure proper installation. I do like this product. I have yet to run out of hot water, and have actually used both showers in my house at the same time and had no problems. Overall this is a good product and I would recommend.
