I wanted to post a shout out to hass for this piece of gear. I know they've been praised here before, but I finally bought one w/ the hope of saving water by not having to run it constantly to hold temp. Well, I installed it today, and what a wonder. I mean, wow. Set it to 72 degrees, and it pegs the thermometer there in 2 seconds and doesn't ever shift. Furthermore, as a note to great service, I'd written and asked if I really needed a filter system for it (budget and space restrictions in mind), and I was given an honest answer that in NYC with the quality of our water, I would probably be fine w/o it. Super answer when they could have given me a default "yes, you do" and squeezed the extra $ out of me. Anyway, stuff this good deserves to be heard about.
