Nice unit, great buy.

do your research about tankless water heaters before purchasing. It's a nice heater, works great. I love that I no longer have to keep a barrel of water hot all the time. I just heat what I need and that's it. If I'm not running hot water I am not heating it and I have noticed a little dip on my gas bill.

Great hot water heater - never run out again!

Very easy install and INSTANT hot water that doesn't run out. We are very happy with it and would highly recommend to others. My hubby was able to install himself after taking out our old hot water heater. We love it!
