    • Great Heater… As Long as You Don’t Live in Narnia
I’m giving this thing 5 stars because it does work great — as long as you live somewhere warm. For a little 6kW unit, it actually performs like a champ when the incoming water is 65°F or higher. Endless hot showers, no problem. But the moment that water drops below 60°F? Yeah… it gives up faster than I do on New Year’s resolutions. It tries, but it just can’t keep up once the cold hits. So here’s the truth: Hot climate? Fantastic unit. Cold climate? Enjoy your motivational lukewarm showers. ... show more

    • Works nicely
We used this at a cabin as a pint of use for our kitchen sink. Not only does it save on hot water for the cabin but it also allows us to wash a lot of dishes in the sink. We don’t have a dishwasher so we do it all by hand. If you have a little bit of plumbing skill you can install this on your own. It is very functional and works as it supposed to. It saves on hot waters and on energy efficiency as well ... show more

    • Reliable and Instant
A great upgrade for my RV - delivers instant hot water whenever I need it. Nice to not have to stand waiting for the water to warm up. The digital display is responsive and makes it easy to control the exact temperature. Installation did require some electric and plumbing expertise, but even in the tight space in my closet, its compact design fit well. No leakage and such a space saver. Endless hot water on demand is really nice. It works beautifully - highly recommend for RV setups, and the value for money is outstanding. ... show more
