Should I Turn Off Water Dispenser at Night?

If you have a water dispenser, you know how essential it is. The appliance makes it easy for everyone to stay hydrated by providing hot and cold water on demand.

But how much does it cost to have clean, pure, and healthy water at your fingerprints? You’ll use energy to dispense hot or cold water from the unit.

So, should you turn off the water dispenser at night? The simple answer is yes. Turning off the water dispenser at night saves electricity, which translates to saving money.

Turn off the unit at night, and you’ll pay less on your monthly power bill.

When Else Should You Turn Off the Water Dispenser?

A water dispenser works around the clock, but this isn’t always necessary. As aforementioned, you do not have to leave the unit on at night when you are sure that no one will be using it.

For instance, if you have a water dispenser in the office, leaving it on at night makes no sense. No one would be using it at this time. Switch it off and save some bucks.

Other times to switch off the water dispenser include:

  • Going on Vacation

If traveling for a vacation for a few days, you should switch off the water dispenser. Turning off the unit when not in use will significantly reduce energy consumption.

  • On Weekends

Turn off the unit if no one is using the office on weekends. You can also turn off the cooling and heating outside working hours.

How Much Power Does a Water Dispenser Consume?

A water dispenser uses between 0.3 to 1.2kWh of energy daily to provide cold water and about 2.8 kWh for cold and hot water.

The appliance’s average power consumption is around 912kWh annually, which will cost you about $118.00.

The power a water dispenser consumes also depends on what it’s used for (cooling, heating, or both) and how often. The heating devices use the most power, usually 400 to 700 watts.

Less power is used for cooling. A thermoelectric water dispenser consumes 60 to 80 watts, and a compressor-cooled unit 100 to 120 watts.

So, what’s the trick to ensuring you get a water dispenser that consumes the least energy per day? It’s pretty simple; just look for the energy efficiency label on the unit label when shopping for one.

A  water dispenser with the label uses less than 0.16kWh of energy for cold water daily and less than 1.2kWh of energy for cold and hot water.

To know the power consumption of the water dispenser, check the energy label, usually located at the back or bottom of the unit. The electrical ratings of the device are usually stamped in terms of watts, volts, or amps.

Can You Reduce the Energy Consumption of Your Water Dispenser?

You can significantly reduce the energy consumption of your water dispenser by switching it off at night. Turning it off during the weekends when no one is using it at your place of work also helps a great deal.

Another way of reducing power consumption is by installing an electronic or mechanical timer. The device allows you to program the switching on and off the dispenser.

You just need to schedule the times you want it running. For instance:

  • On Weekdays in the morning – from 8 to 10.30
  • On weekdays in the afternoon – from 12.30 – 16.30
  • On weekends – 8.30 – 12.00

The timer is very convenient and will help you reduce the power your water dispenser consumes daily.


Turning off your water dispenser at night helps reduce energy consumption. Although the device can work around the clock, leaving it on at night is unnecessary if you don’t need it.

You can also turn off the dispenser if traveling for a vacation with family, outside working hours, and on weekends if no one is using the office.

And to save more on energy, get a model with an energy star rating (View Price on Amazon). These save up to 50% more power.

There’s also a way to conserve more power with a timer switch, which controls the power supply to the dispenser.
