    I can't get enough hot water for a bath with this gas water heater.

    It takes a long time to heat up as well.

    Gas is flowing. I can hear it ignite. All I can do right now is turn the temperature up way too high.

    Apparently I had to turn the thermostat up. From now on, I'll give myself an hour to think about things before I make a post.

    Most water heaters have an indicator showing the normal suggested normal setting.
    If you have to go way above that there's an issue.
    I'd start by using a thermometer to check the temp of the water at another faucet.
    There is no reason it should be above 120 deg.
    If all the faucets are getting low temp. that's one issue, if it just the shower that's an issue with the anti scald valve.

    This thermostat doesn't say numbers. It just says Low --> High.

    I don't think it has a recommended setting. All I know is I hadn't touched it since I got the place in 2016 until yesterday.

    Okay now I don't know what to do.

    I have it set all the way up, and I barely get hot water.

    If this was electric, I would change the element. But it's gas so I have no clue.

    Probably needs a new gas valve, or has lots of sediment buildup. Or both.

    Check your drop tube , you should have one only on the cold water inlet. if someone overheat the fitting then the cold water will by-pass the drop to the bottom and mix hot and cold .
