Arrived undamaged and when installed worked perfectly. Heats water pretty quickly and I am able to take a quick shower -- which was the plan. I am in the middle of a renovation and have plans to install a tankless water heater to replace the old 40 gallon low boy that currently takes up space under the counter in the kitchen. In order to do that I need to upgrade the electrical system to 200 amps. I didn't realize how costly the power upgrade would be so I am saving up. In the meantime the old 40 gallon sprung a leak (of course, right? haha). Well, I didn't want to buy another 40 gallon hot water heater and spend all kinds of money on that for the short term. I live alone, so this was a perfect solution. My only complaint would be that, considering that they recommend draining the unit frequently to rid it of sediment, that they have a drain valve at the bottom. In the instructions they instruct you to disconnect the unit from the water lines, tip upside down, drain, reconnect, etc. etc. That's a pretty mundane monthly (per instructions) chore considering when full it weighs 100 pounds when full of water. Not to mention, that the unit requires a blow off valve be installed just like a full size hot water heater. That's my only suggestion though. The price point was perfect and the unit works great. Thank you.
