Twist the dial on the bottom of the water heater to change the temperature. Gas water heaters are easy—they feature a single knob that controls the amount of heat being directed to the unit. Turning this knob to the left (counterclockwise) will crank up the temperature, making the water hotter.
- Start by turning off power to the water heater at the circuit breaker.
- Find the access panel for the thermostat(s) and use a screwdriver to remove the panel.
- Peel back the insulation.
- Use a flathead screwdriver to adjust the thermostat up or down.
How do you adjust the temperature on a gas water heater?
On many gas water heaters, the temperature control is located near the bottom of the tank. On some, it can be found behind a metal plate. Rotate the thermostat control slightly before testing the tap water temperature. Continue rotating the control until you reach your desired hot water temperature.
Is it safe to adjust the temperature on my hot water boiler?
If it is less, adjust your hot water boiler upwards. If the temperature is well above 120 degrees, you can safely adjust your hot water heater downward slightly before testing again to be sure you maintain the recommended minimum temperature at the tap.
What should I do if my water heater is too hot?
Check the water temperature settings on the water heater control. You can increase the water temperature setting, but beware of scalding. See MIXING / ANTI-SCALD VALVES for a discussion of the installation and use of anti-scald valves to avoid hot water burns, and for a table of temperatures at which hot water burns occur.
How can I Make my water heater more efficient?
Pay attention to where the hand rests, as this will allow you to fine-tune your water temperature more precisely. If your water heater makes use of dual heating elements, make sure both thermostats are set to the same temperature so that one isn’t forced to do more work than the other.

Faulty Heating Element If a heating element has failed, then the hot water heater won't be able to effectively heat the water, resulting in lukewarm water throughout the home. Contact a plumber or a hot water heater technician to repair or replace the heating elements and restore hot water to the home.
Why is water from boiler not hot enough?
The most common issues are: A faulty motorised valve. This valve controls whether hot water from the boiler flows through the coil or through the radiators. If your hot water isn't hot enough but your radiators come on even though the central heating is off, this is highly indicative of a faulty motorised valve.
Why is my hot water only lukewarm?
If your electric hot water heater is only lukewarm, then it's obviously not due to a gas issue. It could, however, be due to a power issue. In most cases, this is because the power source has been cut, most commonly because of a tripped breaker. Fix this issue by flipping the appropriate breaker back to “On.”
Why do I not have as much hot water?

If your boiler keeps suffering from breakdowns, constant repressurising issues or getting too hot, then it will likely be because of a more serious problem. If your boiler it noticeably quite old or in poor condition then this could easily cause problems with the temperature.
How much flow rate should a combi boiler have?
The flow rate is set incorrectly. A combi boiler will need a flow rate of around 10 litres per minute, although some people argue it should be higher at around 12 litres per minute. Putting that debate aside, for now, we can conclude one thing which is that the flow rate is important. If your combi boiler’s flow rate is too slow ...
How many temperature dials does a combi boiler have?
Some models of combi boiler have two different temperature dials one for water and one for central heating. Make sure you are using the right one when you want to change the temperature. If you have altered the temperature on the dials, but things still seem far too hot turn the boiler off and give things time to cool down.
Why do I need a thermostat for my combi boiler?
A thermostat is essential to controlling the temperature of your combi boiler, so if it stops, you will need to call in a professional. A thermostat suffering from problems could cause misreading’s in the temperature it might seem like things are nice and cool only for them to be incredibly hot when you touch them.

How do I open a water heater?
1. Shut off the power to the water heater. Head to your home’s central circuit breaker and locate the switch corresponding to the water heat. Flip this switch to the “Off” position. This will cut off the electricity flowing to the unit, allowing you to open it up without fear of being zapped.
What is the temperature of a gas water heater?
On the majority of gas water heaters, the lower temperature range will be somewhere around 90–110 °F (32–43 °C), while the upper range will top out at around 140–150 °F (60–66 °C). The dial on your gas water heater may not be numbered, which can make finding the perfect temperature a little tricky.
Why is my water heater so cold?
If your water seems unusually cold, the problem may be a broken heating element or poor insulation rather than the temperature of the water heater itself.
What to do if water heater breaker isn't labelled?
If the breaker for your water heater isn’t labelled, it may be necessary to use a multimeter to test for a live current. You’re looking for a reading of zero volts. Don’t forget to tag the correct breaker when you’re done. Remove the access panel from the side of the unit.

How to measure temperature of water?
Insert a cooking thermometer into the hot water. Have your thermometer on standby so you can drop it in as soon as you’ve filled the container. Make sure the probe is fully submerged, then wait 30-60 seconds for it to gauge the temperature. Write down the number you get for reference.
What happens if you don't put a thermometer in water?
If you don’t place the thermometer in the water right away, the water may have a chance to cool down enough to throw off your reading.
Why is my water heater not hot enough?
Insufficient hot water temperature may be due simply to the setting of a temperature control on a water heater or mixing valve, or it may be due to flowing water too fast through a tankless coil. Hot water that is not hot enough can be caused by quite a list of problems, some of which are easy to correct.
What is a solution to a hot tub?

What does it mean when a water heater dips?
Bad Dip Tube Can Mean Water Is Not Hot Enough. Watch out: another water heater defect can also result in hot water that's not hot enough. If the dip tube in the water heater has fallen off or disintegrated, cold water will enter the water heater at its top rather than at its bottom.
What is a dip tube in a water heater?
If your water is heated by an electric, gas, oil, or even solar-heated water tank, the tank probably uses a dip-tube to direct incoming cold water to the bottom of the hot water tank. If the dip tube is leaking (metal dip tubes are often intended to corrode) it may be leaking incoming cold water into the top of the water heater tank.
Why is there no hot water?
Insufficient hot water quantity may be due to the way hot water is being made (a water heater that is too small, a tankless coil on a new small heating boiler, or an instantaneous water heater that is being asked to supply hot water too rapidly. at HOT WATER QUANTITY IMPROVEMENT.
