There are several ways to turn down the thermostat on a water heater. Unfortunately, many models have different ways of doing this. On top the side of the water heater should be a knob that can be turned to the desired temperature. If you don't see this device, check your owner's manual for more specific directions.

Midway down the side of the tank there is a device called an aquastat. It has numbers progressively increasing from left to right. These are the settings that the aquastat's contacts will open when the water temperature is reached shutting the tank off. It is like a thermostat but the sensing element is inside the tank and is surrounded by water. Generally all operate on the same principal, turn the set-point knob clockwise increases the temperature setting and turning the set-point knob counter clockwise decreased the temperature setting.
This happens because the water heater is in the roof or in the basement. When you turn a tap it takes water up or down from the heater down a single pipe. When you turn a second a tap the water being taken down that single pipe is slipt down two pipes and so less water gets taken to a single tap as its being shared.
There is a thermostat inside an accessible panel on the hot water heater. The panel is typically secured by two screws. When the temperature goes below the set level the heater turns on. You'll either see a specific temperature or just an adjustment that says hotter. Some installations have an external timer that might turn off the hot water heater between midnight and 5AM, for example.
It doesn't save much energy because it takes so much energy to reheat the water up to the proper temperature. It is best to turn down the temperature to the hottest you desire it.
If it is a "rotten egg" sulfur smell it is bacteria. Flush the hot water heater and turn up the heat to between 130 and 140 degrees F.
No, and this is a very good energy saving practice.
There has to be a way to turn down the temperature somewhere on your water heater. There is either a dial on a manual control or up and down arrows on an eletronic one.
You will need to know the current water temperature in your tank by using a thermometer, so you know if you need to increase or decrease the water temperature for your fish. Take your heater, place it in the tank according to the instructions, DO NOT plug the heater in for at least 20 minutes. After plugging the heater in, slowly turn the thermostat up until the heater light comes on and turn it back until the light goes out, if the light is on when you plug the heater in, slowly turn the thermostat down until you find the point where the light goes out. You have now just adjusted your heater thermostat to the current water temperature, turn it up or down as needed, but only by a small bit and allow 24 hours for the water to heat up or cool down, before adjusting the heater again.
Yes it is - only when idling and if I turn the heater on it cools down - thermostat?
There is a thermostat somewhere, usually on the wall or on the heater itself. Just turn the breaker off at the breaker box. Label the breaker if it is not already labeled. Once the power is turned off to the unit, you can disconnect the wires inside the heater to permanantly shut down the unit.
Low coolant? Bad thermostat? Plugged or restricted radiator? Bad water pump? When you turn the heater on you are introducing cooler water from heater core into cooling system.
By locating the thermostat and turning it down
First place to look is the thermostat
Switch off lights when you are not in a room, turn down thermostat and water heater by just 1 or 2 degrees, put poly sheet over very large windows.

There should be, and there is. Turn down the thermostat on the water heater to no more than 120° F (49° C). There is no need for it to be any warmer, even if you have a dishwasher, and in addition to eliminating scalding you will save energy.
your heater most likely does shut off. this is called the burner orheat exchanger. the fan will continue to run until the exchanger cools down. check you thermostat setting to see if itis on-auto ,-or continous.
You probably have a bad water pump or thermostat or both. Is the heater working? If not you have a bad water pump. If it works but is not very warm you have a bad thermostat.
