Tankless water heaters normally require 0.5 GPM min. flow rates for activation, what if I'm using a 0.5 GPM (max.) faucet?

Trying to tie geothermal desuperheater to a tankless water heater, but we have a few 0.5 GPM max faucets in the house, and it seems that these would not provide enough flow to activate the tankless heater...?? Thanks Jon Champelli Hyperion Dynamic, Las Vegas

You will have only cold water. The best is to change the faucet with higher flow rate if you want hot water.
