    Are you getting any type of error code being displayed on your remote?

  • Scott Magill May 11, 2010

    Did you just have these installed or have they been in for awhile? have you checked to see if both heaters come on or if just one? have you checked to see if they are piped right? If they have been in for some time then i would check to see if filters need cleaned. I would also have gas pressure checked when both of them are running on high fire to make sure they have enough gas pressure.What size of gas line do you have going to each unit? Do they work fine when you run one or two showers?

Why does water suddenly go cold during shower? It only happens in master bath... guest bath shower does not cause same problem. I have to go outside and unplug and plug back in heater to get it to start...


Try running the hot water in the sink while you have the shower. If the water in the shower stays hot, then the problem is not enough flow through the water heater to keep the heater running. I am guessing that the master bath is further away from the water heater than the guest bath. If not I would check the shower nozzle in the master bath to see if it is clogged a bit or if it is a water saver nozzle because this will slow down the water volume and then cause the water heater to shut off the heat.

These unit is design to operate at a specific flow rate and cannot be ajusted if you need to have a warm shower you will need to get a bath remote where you can turn down the temp whenever you need without disrupting the flow rate

My paloma tankless water heater will shut off in the middle of a shower


I am not sure if this is it but I had mine at too high of a temperature therefore I was not using enough volume of hot water to keep the heater on. They have a minimum amount of flowrate to sustain. Try turning the water temp down to 125-130. Hope this helps

Remove power source from the unit. If remote control is installed; remove cover and lift the control wires on the terminal...can be accomplished from either end. See if the unit runs longer.
If you're receiving any error codes, especialy code 76; contact RHeem customer support at (800-432-8373) and notify them IF you are getting a code "76" error.

Good luck,
