Faucets: 0.75 gallons (2.84 liters) to 2.5 gallons (9.46 liters) per minute.
Low-flow showerheads: 1.2 gallons (4.54 liters) to 2 gallons (7.57 liters) per minute. Older common shower heads: 2.5 gallons (9.46 liters) to 3.5 gallons (13.25 liters) per minute.
Clothes washers and dishwashers: 1 gallon (3.79 …show more content…

One person bathing using a shower head with a flow rate associated with 2.5 gallons (9.46 liters) per minute. Add both the flow rates together. If the particular inlet water temperature is 50 degrees F (10 degrees C), the needed rate of flow through the heater would need to be no more than 3.25 gallons (12.3 liters) per minute. Faster stream rates or cooler inlet temps will reduce the temperature at most distant faucet.
Some units can vary his or her output temperature according to your flow rate and the intake temperature. This is useful when you use a solar heater for preheating the recess water. If, using the previously mentioned example, you connect this very same unit to the outlet of the solar system, it only has to improve the temperature a few certifications more, if at all, with regards to the amount of solar gain that day.
