Thread: Symmons Temptrol Model A Shower Valve

  1. #1

    Question Symmons Temptrol Model A Shower Valve

    I recently installed an electric tankless water heater. My shower has the Symmons Temptrol Model A Shower Valve. I cannot get the shower temperature high enough. How do I fix this?
    The hot wqter at sinks is almost steam. The instructions say to set the level of heating at the heater for the shower but the valve wont let the temperature go to the limit. I adjusted it to the highest temperature using the set screw.

    Talking pressure balanced valve

    you are probably going to have trouble with
    that faucet because the tankless water heater has
    sort of lowered the pressure or the volume on
    the hot side of your system........

    those tankless units can be a pain in the ///


    I am sure you will get some advice form others here

    I have heard of installing a thermal expansion tank on the
    hot side of the system to keep the volume up

    also changeing out the faucet to a non pressure balanced one
    might also be a way to resolve the problem.

    good luck --have fun

    Thanks for the advice. I changed out the shower head to an Oxygenics handheld which reduced the flow. This seems to have solved the problem. We still have some problems with cycling when we reduce the temperature and I am adjusting the output temperature on the tankless unit to see if this helps. Since tankless is a new thing I would appreciate comments from anyone else who has experience with these systems.

    We love the system because never runs out of hot water, it saves money for electricity and there is no tank to take up space in our small condo. We also eliminate the disk of a flood from a leaking tank which is a consideration in a below grade garden condo with electric radiant heat in the tile floor.

    Tankless water heater seem to have a problem with temp. controlled or pressure balanced showers. The manufacturers say it is OK but the two things seem to be at cross purposes. This question is asked frequently, and I don't know if a definitive answer has ever been posted.
