While this heater can’t do what a regular tank-type water heater can, it is OK for a single faucet that isn’t used often. It provides about 120 degree water if the faucet is only opened half way. I didn’t use the flow restricting aerator which was included, as we prefer to have the higher flow rate, and it isn’t difficult to control if we need hotter water.
I selected this particular unit because I have a couple of the higher output tankless water heaters from this manufacturer, and they work really well. The only thing is they require two 40A 220V circuits, and I only had a 30A 220V circuit available for this application. The infrequent use and low-volume needs didn’t justify the expense of the additional wiring to install a larger unit. I just used the existing wiring to the old tank-type water heater, mounted a waterproof junction box to the wall, and wired this tankless unit on the wall next to the j-box. A couple of compression type connectors (the type with the rubber grommet) were all that was needed to secure the existing flex conduit and the wire from the heater to the j-box.
I did purchase two brass bushings to permit me to use 3/4″ NPT male connectors from some braided hoses that had shark-bite connectors on the other end to connect to the copper pipe. That is where I had a little trouble. I couldn’t get the female threads on the bushings to quit leaking where they fit to the 1/2″ male threads on this heater. I had used teflon tape initially, and then tried paste, but neither prevented a slow leak. I had some red loctite handy, and was running out of patience, so that ended up fixing the leak.

The unit functions as it is supposed to and my lack of stars has to do with my own expectations. I was hoping for instant hot water. What it delivers is cool to warm to hot water depending on the rate and duration of flow. It takes about a second to come on once the spigot is open, then you need to tweak the flow of water to get it to 1. get hotter, and 2. stay on. Too slow and it turns off. And if you shut off the hot spigot for a minute or so, then turn it back on, the water that was sitting in the heating coils all that time will be VERY hot — for a second or two — then be replaced by cold water until the unit fires up again and starts heating. So, there is nothing wrong with this product. I was just hoping (dreaming) of endless, instant, hot water.

Customer Questions & Answers


Can the flow rate be adjusted up from 0.5gpm to say 1gpm or 1.5gpm (understood that the output water will be corresponding less hotter)? thanks in adv
Answer: No. This is a simple self- regulating unit. If you want more flow, and more hot water, go to the next size up that this company makes. I put this unit in my parents kitchen, where it doesn’t get as hot and cannot cause burns. I have the larger unit in my kitchen. It can get very hot before it balances out.

Would this provide a decent shower in an RV?
Answer:

Hello. No, the POU 3.5 is only appropriate for hand-washing sinks. This unit heats water by 24??F at a flow rate of 1.0 GPM (and a proportionately lower temperature rise with a higher flow rate, and higher temp. rise with lower flow rate). All tankless water heaters operate on the same principle.

Therefore for exampl??

60 degree water going in what degree will be at the tap
Answer:

Hello James. Great question. This unit heats water by 24??F at a flow rate of 1.0 GPM (and a proportionately lower temperature rise with a higher flow rate, and higher temp. rise with lower flow rate). All tankless water heaters operate on the same principle.

Therefore, you should add 24??F to your incoming water temp??

are any of these tankless water heaters plug in??
Answer:

Hello. According to the NEC and building code, electric tankless water heaters 15 amps or above do not include a cord with plug. They must be hard wired to a junction box or breaker box.

Feel free to ask us any other questions. GadgetsGo is one of the first Authorized Ecosmart Dealers, since 2009.

If i already have hot water but only heats to 125??f, will this unit (ecosmart pou 6 point of use) be able to raise the temperature to 145??f?
Answer: Probably not
