Rated 3.2 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by Cold kitchen hot water The kitchen faucet is the furthest point from the hot water heater. Now, instead of taking long minutes to get warm water. It only takes seconds. A few more seconds and it is hot. Very pleasing efficiency upgrade. January 21, 2014
Rated 1.0 out of 5.0 by water heater had it for a month and it quit working under very little daily use I October 31, 2015
Rated 5.0 out of 5.0 by Hot water for an outdoor shower I bought this to heat an outdoor shower near our beach. I didn't need something to shower a family of four or take long steamy showers, I just needed enough hot water to get the kids cleaned off and it has worked great for that purpose. June 23, 2015
Rated 5.0 out of 5.0 by Good unit for hand sink Installed this unit on a hand sink in my shop. Very good unit for a hand sink, Plenty of hot water. January 22, 2013
Rated 4.0 out of 5.0 by This was the perfect solution, and so affordable! This thing was reasonably priced and takes up barely any space. It was the perfect solution for hot water in a commercial space where no baths or showers are taken. November 13, 2012
Rated 4.0 out of 5.0 by It's always nice when a product does what it says it will. This water heater performs as advertised. It is a relatively straight forward installation that most competent handymen can do without a problem. But be forewarned, as is true in all of life, "There is no free lunch." If you are looking for a lot of hot water get a bigger water heater. It will raise the water temperature 35-40 degrees at 1/2 gpm, nothing more. October 15, 2013
Rated 5.0 out of 5.0 by This is what you are looking for We have a business in a retail space that doesn't have a water heater. We provide bathrooms for our customers, and we have a sink where we wash things for at least a continuous hour a day. These things provide consistently hot water, even with running it continuously for an hour. At another location, we have a 10 gallon hot water heater that runs out within about 10 minutes doing the same activity. I didn't put anything for "Ease of Installation" because we had an electrician and plumber install them. These costs were fairly inexpensive (especially compared to installing a full sized hot water heater). Our electrician wanted to have the unit on hand for the installation to make sure he wired it up correctly. You could most likely do the plumbing part of it yourself -- you just need to T off of your cold water supply. December 30, 2014
Rated 5.0 out of 5.0 by This item is not meant for taking showers This item is not meant for taking showers. It's meant to be installed under your kitchen sink or alike. A very good product and easy to install. October 5, 2013
