### ⭐⭐⭐⭐⭐ Finally, Warm faucet water in winter!
*by B***Y on December 16, 2020*

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!

### ⭐ Not what we expected or wanted with bad design
*by D***Y on May 21, 2022*

This is not a quality product. We ordered a new item but the box came open and was retaped. The "included" hardware was missing. We had been out of water for over a week and had to install this as no store in our immediate area (25 mi radius) sold a mini tank water heater. I'm not blaming Thermflow for the open box or missing parts. This is completely the fault of Amazon. Either they let an opened product slip by the "new" items warehouse or we were sent a pre-used product contrary to what we asked and paid for. Worst case scenario is an employee took a broken product with missing parts and replaced the new item with it. The reason is really irrelevant. The point is that we were sent a substandard item.Once my husband put the parts on and turned it on, it started leaking up top by the values. My husband, who is HVAC certified with over 20 years experience, commented that the pressure relief valve should have been installed at the factory. It also should have had its own valve and roughly placed in-between the hot & cold inputs. At the very least, it should be on the hot output to be able to relieve pressure build up. It shouldn't have been put on the cold input, where the pressure doesn't increase as rapidly. Hubby managed to stop by the leaking only to have us wake up 2 days later to find the kitchen flooded as the unit had (and still is) leaking from under the outermost white plastic cabinet. Out best guess is the Internal tank is busted. This last leak alone is enough for me to say I will never purchase a Thermflow product again. Until I can get a replacement water heater I'm forced to either live without water or have water and a kitchen that completely floods on a daily basis.

### ⭐⭐⭐⭐⭐ A safer tank, Great size and shape, Quiet and simple to install
*by K***R on March 9, 2019*

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.
