When Your Hot-Water Is TOO Hot!


If you feel like your hot-water is way too hot, before you call a professional, check the thermostat. Your water being too hot is usually the result of the thermostat being set at too high of a temperature. If this is the case, verify that your hot water heater thermostat is set somewhere in the range of 110 to 140 degrees Fahrenheit.

One way to test if your thermostat is faulty is to lower the temperature on your hot-water settings. Even if it is set to the recommended range of 110-140 degrees Fahrenheit. If lowering it does not trigger your hot-water heater to turn off then there is probably a problem with your thermostat.

Another thing you should probably check in regards to your thermostat is if it is sitting flush on your hot-water heater. If it isn’t, it could be causing problems by giving inaccurate readings.

If the thermostat is sitting flush, and your hot-water heater isn’t turning off when you lower the settings, then you will probably need to replace your thermostat. This is not an easy task and not recommended unless you have experience in that field. Call a professional for additional help.
