Knowing how to change hot water temp in your home is something all homeowners should know. The comfort of a hot shower, the convenience of sanitized dishes, and the cozy warmth on a cold morning—all depend on the hot water temperature in your home. But have you ever wanted to change your hot water temperature and weren’t sure how? Or pondered what the best setting is for your hot water? If so, read on and I’ll explain how easy it is to do so and what is optimal.
The Ideal Temperature: Safety and Efficiency Combined
Most homes’ recommended hot water temp is between 115°F – 120°F (49°C). This setting strikes a balance between energy efficiency and safety.
At 120°F, you’re less likely to experience scalding. Furthermore, a cooler temperature means reduced mineral buildup in your tanks, prolonging the lifespan of your water heater and cutting down your energy bills. A good rule of thumb is that for every 10 °F reduction in temp, you will reduce your energy savings will be between 3% to 5%.
Types of Water Heaters and How to Adjust Them
There are two basic types of water heaters: electric and gas.
- Electric Water Heaters:
- Single-Element: Locate the thermostat behind the access panel. Adjust using a screwdriver to your desired temperature.
- Dual-Element: There are two thermostats. Typically, adjust the top one first, then the bottom one.
- Gas Water Heaters:
- For most models, you’ll find a dial at the bottom of the unit. Simply turn this to adjust the temperature.
Remember, before making any adjustments, always turn off the power (for electric heaters) or gas supply (for gas heaters) for safety reasons.
Key Takeaway
Changing the hot water temperature in your home is a straightforward process, whether you have an electric or gas water heater. Keep it set at 120°F for a mix of safety and efficiency. As always, consult your water heater’s user manual for specific instructions.
