Tankless On Demand Water Heater Electric 240V, ECOTOUCH 5.5KW Hot Water Heater For Sink, Electric Instant Hot Water Heater, Overheating Protection, Sliver

I bought this for tiny house/hunting cabin project. I have a 50Amp RV power hookup and was looking for on demand water heating for sink and shower. Since it may be a few weeks in between visits to the cabin I was shopping for a unit that is 1) Tankless to avoid keeping water in a water heater tank, and 2) On demand and small enough that would not draw too much power. I was looking at both the 5.5kW and 6.5kW model from Ecotouch and decided to go with the 5.5kW. If you are comfortable with the plumbing and able to install a 30amp double pole breaker for the 240V supply the installation is pretty simple. The unit is surprisingly small and simply hangs on the wall. I have the heater below the sink, and shower stall built right next to it so the pipe is very short going to either sink or shower. From testing so far the heater works as advertised. Easy to turn on and adjust the desired temperature, and after selecting temperature the display switches to show current temp in the unit. In my setup the water is pumped from holding tank in the cabin itself so starting temp stays around 65-67 degrees. I keep the unit set at 110 degrees output. The pump is 2.9 GPM max, so with faucet wide open the water gets warm but it does not get to 110 degrees, as expected from the specs. If closing faucet halfway, at approx 1.4 GPM it does easily reach approx. 100 degrees within seconds, and if closing faucet a little below halfway it will reach 110 degrees at constant flow, but of course water flow is lower at that point. Product specs are - 67 deg water will reach 109 deg at 1.2GPM. I may look for a flow regulator to more precisely test flow rate, but seems to be accurate.Results: The hot water supply to sink works great, as described taking the temperature and flow rate limitations into mind. I have seen other reviews that have used for a shower. My shower stall not quite finished but I will test the output once complete, keeping mind this is a small unit and will not achieve the flow rate of my shower at home for the size. It will probably work as expected.Update: Have been using this water heater the past few years and it has worked perfectly for both the sink and shower, although technically not advertised for shower use. I have a low flow shower head installed and when turning hot water on for about 5 seconds the water is as hot as advertised by the limitations of the unit. If hotter water is desired the flow can be turned down slightly.

overall was built well, simple to figure out wish it was plug n play, i bought it to build a portable system, was not exactly good for that, but it still has potential. they need to add a three pronged powerline option, so one can just plug it in.some may need to hire an electrician to install is the only downside

this technically does heat water but only as a real fine stream.it is real delicate with cheap plastic inlets which are very easy to over tighten and damage the unit.I would not recommend this live and learn

Great product

So the situation is this... office is about 50-75' away from where the traditional gas fired hot water heater is located. The water travels in a non-insulated area that let's face it...the water is cold. The worst part? Takes a good 3-4 minutes to get warm water. Yes, I have timed it and the colder it is....the longer it takes.So I was originally going to put in a lowboy or some other small tanked heater--- then I started to look at the tankless units. For me it came down to what do we really need it for? Bathroom sinks and a sink for the kitchen--- honestly none are used with any amount of vigor, so I went with something that was not too big power consumption wise. This is supported by a 30A double pole breaker and 10ga wire. I have seen some post where people have used 12ga--- that is incorrect wire sizing and although it "works" it creates heat and can easily cause fires, etc. Save yourself or the life of others--- use the correct wire size.So after getting it installed and what we did for our situation was to break in the line and plumb this inline with the gas hot water heater as an assist. PEX and Shark Bite fittings made short work of it all and tying into the existing copper. Leak tested, and let it purge out any air....turned on the breaker and set the temp to 110-degrees. So now it takes a mere 10-15 seconds depending on which sink you use. Water is plenty warm to wash your hands or clean silverware, cups, etc.So overall I am duly impressed. I have really thought about it and in the future I will be buying one for home as I have a 240V/30A outlet for other purposes in my garage that I will use with one of these to wash cars--- warm water always works better and right now I only have cold water. I also have recommended it to a friend that has a pier and a wash station--- same situation in that they have hot and cold, but the the hot takes forever to get there....so they're going to be installing one this spring.

If it has a plug for outlet would be better
