It is a half gal. per minute system. The 'Navy' shower does not work
because the system turns off when the flow stops. There is a
stabilization period and cold water in the line on startup. They work best
with a steady flow and can keep the same water temp for as long as the
power and flow are steady.
You could still use the 'Navy' shower concept to save water but count on
cold water at each startup.

Many of the smaller 110v tankless heaters do not heat to a set temp, they actually just provide a fixed temp rise of the incoming water. We installed a 5000w 220v tankless at my employer for washing hands. During the winter it was barely able to take the chill off the city water. Keep in mind that montreal city water can get down to 40°F in the winter, and never gets above 60°F in the summer.
I believe it was rated at something like 40°F rise at 0.5gpm. A faucet wide open flows quite a bit more than that, and if we throttled the flow to get warmer water, the flow switch would often trip, shutting the element off. We eventually swapped the tankless for a 5gal water heater.

Kingsley Coach,

Les is correct, the low-end units sense flow and turn the heater on 100%,
They do not modulate the heater. The more flow you get the less heat gain.
