This brand is a quality work horse!

This is the third Ecosmart tankless hot water heater, I've bought, in the last ten years, for different locations. From the 11 to the 27 models, I've never been disappointed. They are quality heaters, taking up a tiny amount of space, compared to their large tank models. I gained back a whole closet of space back, by installing this and the other two and highly recommend this brand.

Good Product for the Price

I liked the price. It replaced an identical unit so it went right into place. I wish the manufacturer did rebuilds for these units. The two units that I have replaced probably only need panel replacement to return to working order.

I dislike a leaking tank, or trying to move a huge heavy empty water heater out of the electric room. I do like the speed of hot water reaching our shower in 4 seconds, the vanity in 3 and sink faucet in 4 minutes and the temperature stays the same. And our 18,000 kw Eco Smart heater weighs 12%23, and measures 16" h, 12" w and 4" in depth. most handywomen or men can install in 2-3 hrs when you get all the parts needed. Yea!
