Is there a minimum water flow for the heater to operate? Will it heat water with low flow?

Yes, as long as the flow is high enough to trigger it to turn on heat. See the manual for each model to see how much flow is required to trigger heating. Smaller models have lower flow requirements.

The lowest my pressure goes down to is about 45 psi as I live with a well. The flow control of this "plus" model compensates for that and we always have hot water.

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.

You must be thinking of high energy efficient furnaces that produce condensation moisture and there is a special venting process that allows the water to drain. The process with this heater does not produce moisture, there is no vent, and I have not had an issue.

It just has dials for water flow and gas flow. Not for specific temps. Your incoming water temp is another variable. If your water must be a very specific temp this may not be the right water heater for your application.

Hot water should work fine, but it is too small to heat an entire house (maybe a single room)

Not sure. I don't think there is a solid answer as it depends on your flow rate. I do not recommend this product. It's a great idea but it is very fragile. The heating element is glass. Mine randomly broke and drained half of my tank. I now use an in tank heater that I buried under the gravel

Hello David,Thank you for your question. Water will flow through this heater at 3 GPM, but it won't achieve a hot water temperature at that flow rate. It's only 100v...not very much power. We do sell point of use water heaters that will achieve hot water at 3 GPM.Kind Regards,RossGadgetsGo

Not completely sure but compared to the one I replaced it seems to be low flow. However, I removed the water screen saver(small green plastic piece in the neck of the shower head) and now seems to operate as high flow.

The wattage on this heater is very low at 4. You may not be able to feel the heat

No adjustment on the unit, but water flow can be adjusted with the wall stop (shut off valve). But I don't know why you would want to reduce the flow?

Can't say for sure but it does flow all that is supplied. It is a nice unit. The Manufacturer should be able to tell you the max flow rate.

Yes it produces enough hot water for an average shower. Mine does a great job

I do not think that this valve will give you the required flow while hot water is not being used. It is designed to work in series with the Watts circulating pump and as such I do not think that it will have any effect in a tank-less hot water system.

It is not an inline heater. No tank type water heater is designed for that application. Check tank-less heaters, they will give you a solid 20 degree rise, on average, with low levels of consumption.

You will have to turn the volume of water down. Install a gate valve before the heater and turn it half closed. These are great little units but if the incoming temperature is low they don't have enough btu's to raise the temp that much. Hope this helps.

The faster water flows throughout the unit, the less the increase in temperature over the water input temperature. So, when I want the water to be hotter, I slow the flow through the heater by just closing the cold water valve a bit.

No, not really, it only has one inlet so if you intend to use hot water it will need to be "mixed" upstream of the shower, and you won't have any control of the outlet temp.
