Properly setting up and adjusting your water heater throughout the year can increase efficiency and cost savings. The settings should vary depending on the seasonal outdoor temperature and your household’s hot water consumption. By optimizing the temperature, you prevent water from overheating in summer and underheating in winter.
Recommended water heater temperature setting for summer
During the summer months, the temperature of the outside air and the incoming groundwater is higher. This allows your appliance to heat water faster and more efficiently. Below are the recommended water heater temperature settings for summer:
| Water Heater Type | Ideal Temperature Range |
|---|---|
| Gas | 115°F to 120°F |
| Electric | 115°F to 125°F |
At these lower temperature settings, your water heater will retain enough heat for comfortable bathing and cleaning while saving energy. According to Energy Canada, every 10°F reduction in water temperature can save 3-5% in water heating costs.
Best water heater temperature setting for winter
In winter, groundwater and air temperatures are much lower. As a result, you need a higher temp setting for your unit. Here is the best temperature for hot water heater in winter:
| Water Heater Type | Ideal Temperature |
|---|---|
| Gas | 120°F to 135°F |
| Electric | 120°F to 140°F |
If your water heater is located in an unheated space, such as a garage or basement, the cold air can affect its efficiency. Insulating your water heater and the pipes leading to and from it can help maintain water temperature and reduce energy consumption. Insulation blankets are available for both tank and tankless heaters, providing an additional layer of protection against heat loss.
Additionally, it’s wise to monitor your hot water usage during the winter months. If you notice that your water heater is struggling to keep up with demand, it may be time to consider investing in a larger unit or a system upgrade.
How to adjust the temperature on a gas water heater?
Adjusting the temperature on a gas model requires caution, as these systems use an open flame for heating. Here’s a detailed guide on how to adjust the temperature on a gas water heater:
- Turn off the gas supply Before making adjustments, locate the gas control valve and switch it to the “pilot” position to prevent the burner from igniting during the process.
- Find the temperature dial Most gas water heaters have a thermostat dial located on the front of the unit, near the bottom. This dial may be labeled with settings such as “Low,” “Hot,” or specific temperature values.
- Adjust the dial Turn the dial clockwise to increase the temperature. Turn it counterclockwise to lower the temperature.
- Relight the pilot (if needed) If your model requires manual pilot ignition, follow the manufacturer’s instructions to relight it safely.
- Test the water temperature After adjusting, let the heater operate for a few hours before testing the water temperature at a nearby faucet using a thermometer. Adjust again if necessary.
By following these steps, you can safely adjust the temperature on your gas unit to improve efficiency and prevent overheating.
How to adjust the temperature on an electric water heater?
If you’re wondering how to adjust the temperature on an electric water heater, the process differs from gas models. While it requires a bit more effort, the steps remain manageable with basic tools.
- Turn off power supply Locate the circuit breaker controlling the water heater and switch it off to prevent the risk of electrical shock.
- Access the thermostat panel Remove the access panel using a screwdriver. Most electric models have two thermostats — one for the upper and another for the lower heating element.
- Adjust the thermostat settings Use a flathead screwdriver to turn the thermostat dial. Increase or decrease the setting based on your preference.
- Reassemble the panel and restore power Secure the access panel back in place, ensuring the insulation is correctly positioned. Then, turn the circuit breaker back on.
- Test the water temperature Allow the water heater to operate for a few hours, then check the temperature at a faucet using a thermometer. Adjust if necessary.
