Based on what I'm reading, any flow rate greater than 0.5 GPM will reduce the temperature of the heated water from a faucet? Correct? Thanks!

That's right. The faster the water, the lower the temp gain. I use it for a utility sink in my garage. For occasional hand washing it's greAt, but if you need gobs of hot water, i think you need to go 220v.

The temperature is based more on the temperature of the water coming in than anything else . The unit I purchased was installed on a South American island with ambient water temps in the 80's so I get 1.2 gpm of water to hot to put your hands in , If you are in the northern parts of US or Canada where ambient water is 50 deg the flow rate is going to be greatly reduced checking the local water supply for average temp is recommented Hope this helps Ed P

Charles is correct . . . when you decrease the input (volts) going in you won't get the full rated increase in output (hot water). So if the specs say it will raise two gallons of water say 50 degrees your best case scenario might only be 45 degrees. However, it will still work fine as we installed one in our business that did not have enough juice.

I don't know what that means. To activate, this unit requires a minimum flow rate of 0.15 gpm. The only effect of this for us has been on our dishwasher, which fortunately, has an internal heater. Otherwise, we have noticed no performance difference between this heater and our previous, tanked, heater. Except, of course, that we never run out of hot water anymore and our gas bill has gone down by about 10%.

I have no idea which flow rate I have. I love my faucet though. I find that the hand held spray nozzle has more power. Exceptional value.

I have not installed mine yet but If your water was hotter with the old valve there is likely an adjustment to the mixing valve that will allow more hot water through. I only know this because I watched my plumber friend adjust the mixing valve while holding a thermometer under the water stream. There is a temp you should not exceed to avoid accidental scalding. ie children playing with the faucet. I recommend checking instruction regarding adjustment of the mixing valve.

Well, that's interesting. I stopped using it because it was too low flow, esp when the water was all the way over on hot. The water never felt hot enough and on that setting, there was really no flow at all.

The output temperature is dependent on three things. 1)Input temperature 2)Gas Knob (Burner Setting) 3)Temp Knob (Water Flow) The output temperature but can be lowered quite a bit. Unless your source water is already quite warm I would not expect any issues keeping it below the 85F output. However since the input temperature is what determines the min and max it ultimately depends on your cold water input temp.

Not sure why you don't believe the specs, but now that you mention it there was a very noticeable decrease in flow rate when I replaced my Delta faucet with this one. I don't live in CA so the old one was not low-flow, but this one is.

Yes, you can control both flow rate and temp. caution, these faucet are a little loudwhen turned on but the are beautiful!

This unit produces a mildly warm water source from a cold water source. The water is not hot and will slow down your flow.

Although I cannot confirm the exact 0.25gpm rate, this one will activate and provide constant hot water at very low rates. I use this for a kitchen sink (overkill I know) and at 50% hot/cold it stays warm which has not been the case with other units I've used.

Not really. It initially cuts flow of water to a trickle once it gets warm (around 100F) but once you pull on the cord, it behaves like a normal shower head with no intrinsic temperature regulation. If your water is that hot you may want to lower the temperature on your hot water heater to something a bit lower - instructions are just a Google away. (It is reported that 140F water can scald in as little as 2 seconds, whereas 126F water may take 30 seconds to cause the same injury.)

I ended up choosing a different faucet. Sorry. I dont have any information on the subject. Good luck.

Mr. Eaton: The Rheem RTE9 will have the capability to raise the water temperature the following degrees regardless of setting: 3 gpm=20 deg F; 2.05 gpm = 30; 1.54 gpm = 40; 1.23 gpm = 50; 1.02 gpm = 60; 0.88 gpm = 70; 0.77 gpm = 80; 0.68 gpm = 90; 0.61 gpm = 100 deg F. What temperature you see at the tap is dependent on your input groundwater temp which could be from 40 to 70. If you have selected the first setting (shower/tub), you cutoff temp from the OFW will be 105 deg F. The second setting (kitchen sink) will be 115 deg F. The third (business) will be 125 deg F. So then, if you are taking a shower you want 115 deg F water. In a shower you will need about 1.5 gpm. This means from the above coordinates you will get a 40 deg F temperature rise regardless of setting. So then if your groundwater is lower than (115-40=75), then you will have to draw less than full showerhead nozzle flow to get the desired temperature. You can almost always get the temperature you want with Rheem since it can regulated down to 0.4 gpm, which is really good, but you will have to use a smaller flow rate.

Hello Kim, Thank you for your question. You've provided one key piece of information we need to answer the question, the incoming water temp. But we also need to know which hot water points of use that you might use at the same time, and the flow rates of each. Let's assume they are one shower at 1.5 GPM and one sink at 1 GPM. That's a total flow rate of 2.5 GPM. This heater provides a temp increase of 40F at 2.5 GPM. 45F + 40F = 85F. Therefore, the 10L is way too "small" of a tankless heater. We recommend the 16L which gives a 57F temp increase at 2.5 GPM. 45F + 57F = 102F which is slightly hot water for most people. Kind Regards, Ross GadgetsGo

No but you need a bit of knowledge as far as getting the right shower head ,which is the most important issue here . My dishwasher runs just fine ! . The hot pressure is a bit lower then the cold .But like I said the right GPM shower head and adjusting the temp ,so you are not set at too low of a setting that the Rheem shuts off during use .It just took some fine tuning .The pressure can also be affected by hard water . Use a recommended filter ,or once a year it is simple enough to remove the unit and flush out the core in vinegar or a Lime-Away type product .And you won't lose that extra bit of pressure that the water filter can cause .Mine is well into its second year of use with no problems at all ,once I tuned it to my needs :)

Absolutely not, this is a mixer only and a very temperamental one at that. And is a flow restricting valve as well. It would work well for you if you want to turn on the water to a temperature, and leave it, but other than that, it is unable to change the rate of flow.
