Bests & Worsts Reviews from Amazon

I bought the Eco 11 and the aquapure pre-filter in Nov 2012. So it's 5+ years old and still going strong. We're a 2-person household and have 1500 sf house, single bath/shower, dishwasher, clothes washer. We never run anything at the same time as the shower so I can't say how it would do for multitasking but, for our purpose, it works great. I replace the pre-filter as needed and haven't had any problems with the heater. We have hard well-water with a high level of iron but I have 2-stage, 30 micron filters for the whole house (no softener), and the aquapure pre-filter does final cleanup. The water comes out of the ground at about 50F and I set the control to generate 112F output, so we do have to run the water for a couple of minutes for the 20-foot run to the plumbing wall. What I really love about it is that I was able to replace an electric 40-gal heater, that took up half of a 3' x 6' closet, with a unit that hangs on the wall and is about the size of a shoe box. Since this runs on a 60 amp breaker we did have to pull #6 AWG wire, which was kind of a pain, but that's my only complaint. I'm back on this page to check current prices for another one for my workshop, so I thought I'd add my review.
