Rated 5.0 out of 5.0 by FirstTimePlumber Review Update August 2014 to May 2016
I've now had 2 units for almost 2 years and I have never had any issue with them at all. For better or worse, I haven't looked into maintenance at all (which of course I don't recommend), but each still provides hot hot water, one at the kitchen sink and dishwasher, and the second under the bathroom sink.

Installed under the counter for the source of an instant hot water tap. Used quick-connect fittings so removing the lines to drain it & change the element when necessary will be quite simple (it has no drain valve). Will install one in a bathroom remodel that's at the other end of the house from the water heater so no waiting for a hot shower.

Rated 3.0 out of 5.0 by DaddyMonster This is a replacement.
It was easy to install because I was replacing one that failed. It was 4 1/2 years old. I hope this one last longer.

Rated 1.0 out of 5.0 by davidicusrex Nearly useless
It heats a VERY small amount of water to wash a few dishes then it turns cold. One would assume that I could actually get 4 gallons of hot water but it mixes with the incoming cold and it becomes lukewarm quite quickly. If you are using water that comes from a well and it's cold this will take forever to get it hot. I regret that I threw away the box as I would have surely returned it.

The first one had a six year warranty. I have just requested the fourth (4th) water heater, since the first three failed during the last five years. At $200 per removal and installation, the cost is excessive. Very unreliable.

Rated 3.0 out of 5.0 by JTinTX Does not last long
This unit heats fast and provides a good amount of water for light jobs. We bought it to replace a tankless natural gas water heater that failed due to cold air coming down the flu pipe causing the tankless heater to freeze and rupture. We thought that having a small electric unit like this would be more reliable but still sufficient for our sink water and dishwasher. It works fine for that and we rarely run out of hot water. We also love the instant hot water since it could not be any closer to the faucet.
However after 4 years we've had to replace this Ariston unit twice due to leaking tanks ( we're on number 3 now) so it is NOT hassle free. Not sure on what planet will the tank last 6 years per the warranty. I've had water damage twice now due flooding. Although not called for in the instructions, this time I've placed the unit in a water heater pan with a drain!

Rated 4.0 out of 5.0 by joelmc Great little water heater!
We have had an issue with waiting for hot water at the kitchen sink for years. Recently I purchased and installed this unit in-line with my household water heater under the kitchen sink. It works fantastic! Easy to install, no leaks, hot water when we need it. It also looks to be very economical. I've had it on a KWH meter for a few days and it looks like it will only use about 50KWH per month which equates to less than $5 per month in my area. Worth every penny! The only reason I didn't give 5 stars is that the manual doesn't give any information about how to plumb the pressure relief drain but I was able to figure it out myself.
