Your in florida, for home or rv use you only need to heat the water 30-40 degrees to get the temp you want, from an rv tank you may not need even that much, but as temperature range changes increase, the difficulties regulating it do as well.

I have used changing water pressure less than 20 lbs to 60 lbs (a well pump system) with no problem regulating water temperature.

The main point is to have only the hot water faucet turned on. Having he hot and cold water turned on provides a path for cold water to the shower head, and causes the tankless heater to have less water go through it. That situation causes the tankless heating unit to turn off prematurely, and cold water continue to flow.(burr!) The tankless heater should be set to the desired shower head water temperature. Let it do its job.

So it sounds like in a home that it's a learning curve. Most people don't want to change their habits and don't want to learn new things.

That being said, it also sounds like it might not work as well in a RV where the parameters of flow usage and other things can change.
