    • Use 2 of these in different ways, excellent results!
Style: 4.0 Gallons
I purchased one of these for my Florida office and it works extremely well to deliver instant hot water for hand washing, etc. I purchased another one as a pre-heater for an addition on home with long lines to the primary hot water tank. This works superbly! Instant hot water for hand washing, instant hot water for shower until the main hot water tank takes over. For the shower, the cold inlet comes from the main heater tank and the outlet feeds the shower and wash basin. Works very well, saves time and water because you needn't let the faucet run and wait for hot water to come from main tank. Love the results! Excellent product and excellent results! ... show more

    • Cheap fittings included in the package.
Style: 4.0 Gallons
Purchased. Had a plumber stop by to install although it appeared to be a simple installation. Plumber left and water heated up. However, after a couple of hours one of the fittings included in the package simple broke where the treads connect to the housing of the fitting. Obviously, water flooded our kitchen and my wife and I spent a couple of hours cleaning up the mess after we were able to shut off the water supply. Thankfully, we were present when it happened or there would have been major damage to our home. We have now called back the plumber and instructed him to replace not only the broken fitting, but also the other fitting as well. These are cheaply made brass-like fittings and I do not want to have to worry about them breaking again, so I'm replacing them with quality fitting. Suggest you do the same if purchasing any of these units that come with fittings. ... show more

    • Finally, Warm faucet water in winter!
Style: 2.5 Gallons
After suffering through winter after winter of cold faucet water in our patient bathroom, and after plumber after plumber said there was nothing which could be done other than wrapping pipes with plug-in pipe warmers (which did not work), I conducted my own research and came across stand alone water heaters. I read through reviews of many such products and saw complaints about rusting and product failure. I kept researching until I came across this product and felt confident in purchasing it. My contractor installed it after needing to install a water-resistant outlet in the bathroom and after drilling into the drain pipe and connecting the hoses. Since our patient bathroom sink has to be accessible to wheelchair patients, there is no cabinet underneath the sink. I wish this water heater tank was able to be attached to the wall but the directions say not to attach. So my contractor built a small platform for the tank to rest on so that the tank does not get contaminated when the bathroom floor is mopped. Normally by the time a person is done washing their hands, the faucet water is still ice cold. But now within a few seconds of the faucet turning on, they get warm water to wash their hands for as long as they need to wash them! I am so happy I purchased this product! ... show more

    • Scalding hot on lowest setting
Style: 2.5 Gallons
UPDATE 8/3/2019 I contacted Thermoflow at the contact information they provided in their comment. While all that was really needed was a new thermostat for the heater, they did send out a complete replacement. I changed the water heater out this morning and the heater is now working properly. Thus the change from a 1 star rating to a 4 star rating. I would have given 5 stars if the fittings included made sense from a plumbing standpoint here in the US, but they don't. They would have been better off using true 3/8" pipe threads coming out of the water heater, but I believe they are something other than 3/8" pipe thread, possibly 3/8" straight threads because you need to use a rubber gasket on the included adapter. And the description says it's a 1/2" pipe connection, but that's not true without using the provided adapter fitting. ORIGINAL REVIEW: I purchased this in February and haven't had time to install it until now. First, the 3/8" pipe connection on the unit itself are not standard pipe threads. This makes it more difficult to install if you need to make some odd connections. Second after install no matter where I set the temperature control, even on the frost protection setting, the unit does not turn off resulting in scalding hot water coming out of the faucet. I wish I had time to install it back in February. I would have returned it to Amazon. But alas, that time has passed and I'll have to look for a different hot water heater. ... show more

    • A safer tank, Great size and shape, Quiet and simple to install
Style: 2.5 Gallons
After looking at a number of products that make the buyer do the protection from hot spots in the take (by adding a pressure valve that needs a drain, This product seems to take care and heat more evenly and without creating local steam from a too hot too small a heating element. Turning on for the first time I listened very close for the characteristic hiss or Pop from over aggressive heating elements - NONE Totally quiet! and the Heat time was very reasonable even quick - Temperature control very smooth with plenty of range. Size was great - having it built to SIT on the counter floor rather then requiring hang on the wall a real plus. One hit - The tank list NPT 1/2" fitting. Typical USA this is called a "compression Fit" and is NOT a FIP. And Most sinks and faucet connections are smaller, 3/8" . After a bit of fussing I found a 1/2 to 3/8 compression adapter (home depot etc) that fixed that - but I did have a challenge from the tank needing to be farther then the 30" lines available in hardware store - Found a great 4-foot with 3/8 compression on both ends from Amazon - which fit the bill perfect. only took 15-20 min to install once all the parts were found. ... show more
