How do I reconcile an electric, tankless water heater and low flow faucets?
I have installed my first tankless electric water heater. It is an RP27PT single phase Powerstream Pro Redring, made by BBT North America Bosch Group. It works fine at the washing machine, or, if you turn on multiple valves but any one, by itself, will not activate the heater. After a couple of hours on the phone with tech support, I believe our low flow shower valve, vanity faucet or kitchen sink faucet, do not allow enough volume of water to pass through the heater to activate it. We have 45psi water pressure at the heater. California requires a min 20psi in muni systems so I would think we should be within an acceptable range. Any advice?
