I am surprised that no one asks for a chart of temp increase compered to GPM flow. Is there a chart that will supply that information?

my husband says it is variable..we are still learning about ours..look up on line you will see maximum flow rate based on temp of water coming in and output water temperature

I don't usually wander to far out of my current fishing range and all seems to be good.....as suggested i would say to contact Garmin and ask them if there is any kind of an update to that chart. Sorry I can't be more helpful.ER

2.2GPM , but flow rate has more to do with how many GPM you can supply than PSI . For example- if you have 1/2" water lines you will have higher PSI than 3/4" lines , but you will have more GPM with the 3/4" lines.

According to Rheem's specs a 75 degree rise would give you a flow rate of around 5 gpm. Check Rheem's website and review the technical document for this water heater to get the complete picture.

I installed the pump to about 300 feet with plenty of water. There is no GPM adjustment, however the pump will shut off if the water level in the well is drawn to the pump level, this protects the pump.

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%.

Occupants has nothing to do with this question , it's gallons per minute{ GPM} The hot water flow that you need is what you need to know, Input water temp. has little effect when buying like I do, With a bucket measure the water flow at a shower if it's 1.5gal a minute then buy a 3GPM unit and you will love it like I do mine. Remember over kill is best

It took me studying the graph that came with it and a couple of searches on web for liquid measurement equivalents in order to get the solution I needed. Don't have the graph that came with it so I can't venture exactly how to get 400 ppm right now. If studying the graph they sent doesn't help you, write again and I will track down my graph before responding next time.

I have not been able to find a conversion chart either. Sure would help if we could find one.

I don't know about the gpm; I had a plumber install. My water pressure and flow rate from the faucet is really strong.

According to EcoSmart Site, an Inlet temp of 37 degrees will produce 1.81 GPM Steady State on the ECO 18. At 44, you would be able to produce about 2.0 GPM Flow Rate. http://www.ecosmartus.com/products/electric-tankless/eco-18/#product-tab3 I agree with Cliff. I am on my Fourth Tankless: two gas, two electric. This is by far the best design. The internals, wiring size, simplicity, layout are impressive. Best Value for the $ that I can see. My last electric was aweful. A soon as the flow rate would drop in the head, the heater wouldn't kick on. The ECOSmart has a proprietary sensor that kicks the system on even with a low flow rate. That is a great feature, as all three of my other ones required at least 1.0+ GPM to kick on and stay on. Best wishes.

I watched it count up by single increments, but I didn't watch it for long. I believe that it tops out at 65C, as others have said. It can be set and will hold the temp.

rheem website states 4.9 gpm at 77 degree rise I am hvac tech suggest pro help on install very good install instructions come with heater don't hurry install make sure gas pipe is big enough

I guess I will be the voice of dissent, but our unit has struggled significantly. With a 1.75 gpm shower head and a 1.5 gpm faucet you most definitely feel a temperature drop in the shower. This unit has definitely underperformed the manufacturer's specs.

stickly LP gas and knob is not marked for temperatures, just low, med., and high (ranges)/temps so don't know what actual temp high is.

Depending on supply water temp, flow volumn and pre-temp it will amperage will vary. Once the primary element cannot maintain the pre-set temp the secondary element will gradually start coming up. Although I've not checked it I assume with both elements at max output you're going to be close to reaching 80A.
