How to adjust your water heater temperature
No one enjoys taking a cold shower. It’s much worse when you are scalded when the hot water is turned on. It is critical to correctly regulate the temperature on your water heater, not only for your health and safety, but also to save money on your power bill. Here’s how to regulate the temperature of your water heater to save money while also protecting your skin from sun damage.
The correct temperature range
It is recommended that your water heater be set within a specified temperature range for a variety of different reasons. A low temperature setting not only results in hot water that is merely lukewarm at best, but it can also promote bacterial development, which can lead to illnesses such as Legionnaires’ disease. This may be avoided by adjusting the temperature of the water heater to a level at which the bacteria Legionella cannot survive. A temperature of at least 140 degrees Fahrenheit (60 degrees Celsius) for water heaters is recommended by the Occupational Safety and Health Administration (OSHA) to prevent Legionella and other germs from growing in the water.
It reaches 150 degrees Fahrenheit (66 degrees Celsius) when exposed to heat.
Adjusting water heater temperature
The interface used to control the temperature of a water heater will differ depending on the kind and model. Fortunately, the majority of water heater models can be modified in the same way. For example, most contemporary gas and electric water heaters are equipped with a thermostat concealed behind an insulated access panel. Electric water heaters are frequently equipped with two thermostats: one at the top of the tank and another at the bottom. Furthermore, most tankless water heaters include a display with a temperature reading as well as controls for altering the water heater’s temperature.
Turn on the water in the bathroom or kitchen sink and let it to run until the water is completely hot before using.
The process of adjusting a tankless water heater is quite similar to the process of adjusting your air conditioning thermostat. Adjust the temperature by using the digital control panel, which may be adjusted up or down as desired.
Gas or electric water heaters
Some gas water heaters include a dial towards the bottom of the device that may be adjusted simply by turning it – no tools are required for this operation. Nonetheless, most current tank water heaters (whether gas or electric) require a bit more effort, but the process is still straightforward and should only take a few minutes.
- Turning off the water heater’s electricity at the circuit breaker is the first step. To remove a thermostat(s), locate the access panel for the thermostat(s) and remove it using a screwdriver
- Remove the insulation by peeling it back. To adjust the thermostat, use a flathead screwdriver to turn it up or down.
- If your water heater has two thermostats, make sure they are both set to the same temperature. The temperature on the top thermostat should be a few degrees higher than on the bottom thermostat.
- Replace the insulation and re-install the access panel, if necessary. Reconnect the water heater’s power supply
- It is possible that you may need to relight the pilot light on a gas water heater.
Once you’ve made the necessary adjustments, you should wait at least three hours before checking the water temperature once more. It is possible that you may need to make more modifications in order to get the desired temperature. If you’ve increased the temperature and are still getting chilly showers, it’s possible that your hot water heater has to be serviced or completely replaced.

How to Adjust a Hot Water Heater
Documentation Download Documentation Download Documentation There is a delicate balance between the temperature of the water in your home—too high, and you run the danger of getting scalded; too low, and you’ll be shivering in your shower. Fortunately, regulating a hot water heater is a straightforward process if you go with caution. For your own safety, turn off the electricity to the water heater at the main circuit breaker in your home’s electrical panel. Afterwards, remove the access panel from the unit’s side and use a flat-blade screwdriver to increase or reduce the temperature in accordance with the temperature ranges specified on the control dial.
- 1 Determine whether or not the temperature of your water has to be adjusted. Most manufacturers recommend that the water used in your homestay be kept at a temperature of roughly 120 degrees Fahrenheit (49 degrees Celsius) for safety reasons. The temperature of most water heaters will already be adjusted to this level when they are installed. In most circumstances, it is advisable to simply leave it alone in order to reduce the danger of harm.
- Instead of the water heater’s temperature being the source of the problem, it’s possible that a faulty heating element or inadequate insulation is to blame. A trained plumber can assist you in diagnosing and repairing a malfunctioning water heater.
- 2 To adjust the temperature of the water heater, turn the dial on the bottom of the unit. Gas water heaters are simple to use
- They are controlled by a single knob that regulates the quantity of heat provided to the unit. Turning this knob to the left (counterclockwise) will raise the temperature, which will result in hotter water being produced. It will cool down if you turn it to the right (counter-clockwise).
- The lower temperature range of the vast majority of gas water heaters will be anywhere between 90 and 110 degrees Fahrenheit (32 and 43 degrees Celsius), while the upper temperature range will peak at roughly 140–150 degrees Fahrenheit (60 and 66 degrees Celsius). It’s possible that the dial on your gas water heater isn’t numbered, which makes determining the ideal temperature a little more difficult. To get around this, just take the temperature of the water several times after making changes to your settings and write the exact degree reading on a piece of paper or on the dial itself.
- s3 Increase the temperature of the water to enjoy warmer water for cleaning and bathing purposes. It is advantageous to have hotter water in your house for a variety of reasons. For starters, it may make taking a shower or soaking in the tub more enjoyable, because you won’t have to worry about running out of hot water as fast as you would otherwise. This method may also be used to increase the performance of appliances that do not utilize warmed water (such as dishwashers and washing machines), which will aid in cleaning filthy things.
- Heat is more effective in killing most common bacteria, including health-threatening pathogens such as Legionella, E. coli, and staphylococcus
- Higher temperatures kill more germs. Avoid heating your water to a temperature greater than 120 degrees Fahrenheit (49 degrees Celsius). A substantial danger of burns, particularly for youngsters and the elderly, can result from this practice.
- Increase the temperature in order to save money on your energy bills. Heating significant amounts of water quickly becomes prohibitively costly. Lowering the temperature of your water heater to the range of 100–110 degrees Fahrenheit (38–43 degrees Celsius) will help you save money on your next heating bill. Even a minor adjustment can result in significant savings over the course of a few months.
- Be aware that your water will not be as hot, which may have an influence on your comfort or the degree of sanitation for cleaning tasks.
- Step 1: Turn off the electricity to the water heater. Locate the water heat switch on your home’s central circuit breaker panel, which should be located near the water heater. Make sure that this switch is in the “Off” position. This will interrupt the flow of electricity to the device, allowing you to open it without worry of getting electrocuted
- Do not attempt to make any changes to your water heating system until you have double checked that the power has been turned off. Depending on whether your water heater’s circuit breaker is clearly labeled, it may be essential to use a multimeter to check for a live current. Zero volts is what you’re searching for in this case. Keep in mind to label the appropriate breaker after you’re finished.
- 2 Remove the access panel from the unit’s side by pulling it out. Identify the two screws at the top and bottom of the panel and loosen them with a flat-bladed screwdriver to complete the process. Pull the panel away from the body of the device and place it somewhere safe and convenient for you. Take cautious not to loose any of the screws.
- Some versions may have a second plastic cover behind the metal access panel, which can be difficult to see. With a little tug, you should be able to gently remove it.
- 3 Remove or push the insulation that is covering the thermostat to the side. An additional layer of insulation is installed within the water heater. If it’s a single piece of styrofoam or similar material, you’ll be able to just lift it out with your hands. Using your hands, move fiberglass insulation out of the way so that you can get to the thermostat controls
- It is necessary to insulate a water heater in order to prevent heat loss and guarantee that measurements are more accurate.
- 4 To adjust the temperature, use a flat-blade screwdriver to raise or reduce the setting. The temperature ranges for the high- and low-ends of the temperature scale will be displayed at the bottom of the thermostat. To adjust the temperature, insert the tip of a screwdriver into the colored adjustment screw and turn it clockwise. When you twist it to the left (counterclockwise), the temperature will decrease, and when you twist it to the right (clockwise), the temperature will raise.
- The adjustable screws on contemporary electric water heaters are equipped with indicator hands that inform you roughly how hot the current setting has been set to. Attend to where your palm settles, since this will help you to fine-tune the temperature of the water even more accurately
- In the event that your water heater has two heating elements, make certain that both thermostats are set to the identical temperature so that one isn’t required to perform more effort than the other.
- 5Replace the insulation as well as the access door. When you’re pleased with the new temperature setting, return everything to the way it was when you first started. Make certain that the insulation completely covers the internal thermostat before reinstalling both protective covers and tightening the screws to fasten them. 6 Restore electricity to the water heater if it has been disconnected. Return to your main breaker panel and turn on the water heater by turning the switch to the “On” position. Please refrain from making any additional adjustments beyond this point since the electricity will be back up and running.
- The flowing water temperature may not reach its maximum temperature for up to an hour after your unit has been turned off for a lengthy period of time
- This is normal.
- 1 Fill a glass halfway with boiling water. Set a timer for one minute and turn on the nearest faucet to the water heater to start the process. Keep a drinking glass or similar container under the stream until you’ve captured a few inches of water
- Until the water is as hot as it can possibly be
- It is preferable to utilize a container that has been kept at room temperature in order to obtain the most accurate reading possible.
- Cooking thermometer: Place a cooking thermometer in the boiling water. Prepare your thermometer in advance so that you may put it in as soon as the container is completely full. After making certain that the probe is completely immersed, let 30-60 seconds for it to determine the temperature
- Make a note of the number you get for future reference. It may assist you in determining the optimal temperature range for your house, as well as identify any heating problems outside of the unit itself. If you don’t put the thermometer in the water straight soon, the water may have a chance to cool down sufficiently to cause your reading to be inaccurate.
- 3 Determine whether or not the water is sufficiently hot. You may be confident that your water heater is operating at peak performance if the temperature is at or near 120 degrees Fahrenheit (49 degrees Celsius). If the temperature is any lower than that, it may need to be raised a few degrees. Keep in mind that temperatures surpassing 120 °F (49 °C) will be too hot for the majority of people in their homes.
- Increase the temperature of your water by 10 degrees at a time to lessen the chance of burning yourself
- 4 Wait three hours before checking the water temperature again. It will take some time for your water heater to adjust to the new temperature setting, so please be patient until it reaches the required temperature. Hold wait on taking a bath or turning on any appliances in case the water being circulated is hotter than you anticipated
- In the meanwhile
- Make any required modifications before everyone in your home begins their daily routine
- Otherwise, they will be inconvenienced.
