Welcome to Your Guide to Water Heater Safety
Warm showers can be one of life’s simple pleasures, but there is nothing pleasant about scalding hot water rushing out of your showerhead or faucet. If you own a water heater, it’s essential to know how to adjust the temperature and maintain your unit’s safety.
In this article, we’ll provide step-by-step instructions on how to adjust the temperature of your water heater, discuss the advantages and disadvantages of temperature adjustments, and answer frequently asked questions on the topic.
How to Adjust the Temperature of Your Water Heater
Before you start, it’s essential to know that adjusting your water heater’s temperature can be dangerous if not done correctly. You should always follow the manufacturer’s instructions and take the necessary precautions to avoid burns, shocks, or other injuries.
Step 1: Turn off your water heater. This may require you to turn off the gas or electricity supply.
Step 2: Locate the thermostat. This is typically a round dial on the side of the water heater or a digital display.
Step 3: Use a thermometer to test the water temperature at a faucet or showerhead. The ideal temperature is between 120- and 140-degrees Fahrenheit for most households.
Step 4: Adjust the thermostat to the desired temperature. If you have a gas water heater, you might need to relight the pilot light afterward.
Step 5: Turn on the water heater and wait for the water to heat up. Test the temperature again to ensure it’s what you want.
Step 6: Consider insulating your water heater to improve energy efficiency and reduce heat loss.
