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.

How is an electric heater hot water heater turned on?

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.


Why does the flow of water decreases in the tap when person open other tap in the same building?

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.

How do you set the aquarium heater without boiling them?

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.
