Any tips on the tankless water heater

Has anyone mastered the Garrard tankless water heater? After 3 weeks of using the water heater, I still have not been able to take a shower without the water getting cool. Have plenty of water pressure (about 40psi) and I make sure that there is no air in the system. Not sure what else to try. Any tips?

I set my thermostat about halfway. I run just hot water for a few minutes then move the shower faucet about to the half way position the temp does change a little but I wouldn't call it cool to hot, more like hot to warm..

I do the same. I also use a Oxygenics Body Spa Handheld Shower Kit, White
Oxygenics (69). That seams to help also. I change the thermostats with the outside temp a little at a time. Always full blast and about in the middle between hot and cold.

Having one in the house prepared me for the RV. It is the flow regulator in the shower head. May not be the best for water conservation when you are running off the tank alone, but I would be surprised if you removed the regulator or swapped it out and the problem didn't fix itself.

it has a low/high switch , put to low for showers, and turn the hot water knob only... in some areas where the ground water is warm , like above 60 degrees their is a mod to fix this issue, I had lots of issues with mine last year and spent a bunch of time on the phone with the techs at girard, finally got it to work right, and it is nice..

Questions....
Have you ever gotten a lot of hot water out of it ever?

Is the bypass valve open?

I run the water and I get very hot water from my shower head (Oxygenics) and after the water is flowing very hot, I adjust it to a comfortable temperature. While showering the temp varies from hot to tepid. Not sure why the temps vary and that is my problem.

I've learned that the shower control always allows some cold water through. I shut the cold water to the shower off at the outside manifold in all but the warmest weather in the summer. We then use the auto (which is wired as high) / low switch to keep the kids from burning themselves.

After reading most of the threads on the forums, I've already decided, when ours dies, I'm going back to one with a tank. I can make the shower work, but I hate living with the cold blast while trying to wash the dishes. In my opinion, it wastes too much water when dry camping waiting to get the long line from the heater to the shower / sink warm when starting either.
