  • Packs a punch...works with three adults in the house.
This water heater is more than I expected. We were able to install it ourselves. Long hot showers!

  • Doesn't work
Doesn't get hot nor maintain temperature.

  • Not really useable.
Not really of much use. It will only heat 1.6 -1.8 liters of water per minute which isn't much water. The temp cannot be any warmer than 113°. Any warmer and the unit will not keep up. Even if the heater is wired on its own circuit with #10 gauge wire and a 30A breaker, it will trip the breaker if the water runs longer than 3-4 minutes. ... show more

  • Slow Flow = Hot water..
It CLAIMED hot water “FASTER”. . Well, no, not really. Customer service seems to be good, since the first one sent to me ran for a few minutes, then died. They sent me a replacement fairly quickly. I looked online for temperature of a hot shower; then raised this unit’s to 110. The flow has to be pretty low for it to reach being HOT; but after not having ANY hot water, I guess THATS why I left 3 stars. If I can figure out how to get stronger stream AND hot water BOTH, I’ll bump it up to 4 or 5 stars. ... show more
