Shower Head Gallons Per Minute and Tankless Water Heaters

QUESTION: We recently installed a Bosch Aqua Star 250sx tankless hot water heater and are finding that the shower does not allow enough Gallons per Minute to run the unit? I have totally cleaned everything of any build up that might effect the rate, but nothing has helped. We are on a well that is at a constant 50psi. Do you sell any hand held shower units that might
allow more GPM's?

ANSWER: The minimum flow rate on the Bosch Aqua Star 250sx tankless hot water heater is 0.8 GPM. Given that you have 50PSI, all the showerheads and hand held showers available through the Shower Store run about 2.5 GPM at 50PSI, which should be enough for your unit.

If you would like to increase the amount of water your showerhead uses, check our section on removing the flow controller.
