How to Adjust your Water Heater Temperature

Adjust your Water Heater Temperature

Do you know what temperature your water heater is set at?

If your household is like most, you likely have people in your home who like cool showers and those who like the temperature a little warmer. Everyone is different when it comes to how they like the temperature of the water they use and your water heater needs to be set to keep up with each person’s desired temperatures. The temperature that your water heater is set at can be too high or too low. We are going to review how to adjust your water heater temperature to get it just right and keep it within the recommended range.

What is the Recommended Temperature for a Water Heater?

Before you decide that it is time to adjust your Buffalo, New York water heater temperature, you should understand what the recommended temperature is and why. Having a water heater that is set at too high of temperatures can make even tap water dangerous and cause burns. The EPA recommends a hot temperature setting of 120°F for both safety and energy-saving purposes.

Some manufacturers set water heater thermostats at 140°F; however, most new water heaters are preset at the recommended 120°F. At 140°F, water can cause scalding and a third-degree burn within five seconds.

How can you Adjust your Water Heater Temperature?

Adjusting your water heater temperature depends on the water heater. You should always consult your manufacturer’s user manual before diving in and even then, it may be best to contact a local water heater repair expert to help.

If you need to adjust your water heater temperature, below we outline the basic steps to follow.

– Locate the temperature dial on your water heater. This is usually a single knob that controls the amount of heat being directed to the unit.
– Turn the knob to the left (counterclockwise) to increase the temperature, and turn it to the right (clockwise) to decrease it.

It can be tricky to find the right temperature because most dials aren’t labeled with the numbers. If this is the case, follow these suggestions for getting your water temperature right.
– Run hot water at the tap closest to the water heater for at least three minutes.
– Fill a glass and check the hot temperature with a cooking thermometer.
– If the water is above the desired temperature, adjust the dial, wait about three hours and check again.
– Repeat until you get to your desired temperature.

Adjusting your water heater temperature can be tedious and take some time to get it just right.
