Household Flow Rates
Taken from UPC 2006
ͻ
The flow rate through the water heater is limited
to a maximum of 6.6 GPM (25 L/min) for the 240
model, 8.0 GPM (30 L/min) for the 340 model, and
10.0 GPM (38 L/min) for the 540 model.
ͻ
The temperature setting, along with the supply
temperature of the water will determine the flow
rate output of the unit.
ͻ
Please refer to the temperature vs. gallons per
minute charts on p. 64 to determine the likely flow
rates based on your local ground water temperature
and your desired outlet water temperature.
ͻ
Refer to the table to the right for typical
household plumbing fixture flow rates to determine
what the water heater can do in a household
application.
