The temperature of my hot water seems to be higher than what I think it needs to be.

The new standard temperature that manufacturers use when presetting your water heater at the factory is typically 120 degrees Fahrenheit. This is a sufficient temperature for most households. If you have an older model, you can set the thermostat at medium. Gas models usually have a dial on the front of the gas valve. Electric models have thermostats — there may be two — that are concealed behind the two panels on the side of the tank.

You can adjust the temperature to meet your needs. Keep in mind that hot water also helps in minimizing the growth of bacteria.NOTE: Turn off the electricity to the water heater before performing any personal maintenance. There can be exposed wires behind the panels that may result in extreme shock.
