The amount of electricity consumed by a water dispenser is dependant on the voltage and amperage. A 120V plug will consume about 3 watts running the machine for an 8-hour day, or approximately 0.25 kWh over that time period. A 240v outlet will similarly consume about 2 watts, or 0.17 kWh over that time period.
Lets us discuss in some detail that includes, including how much electricity a water cooler uses, why different voltages consume more or less energy, what the differences are in wattage and kilowatt consumption between 120v and 240v plugs.
How Much Electricity Is Consumed by a Water Dispenser?
Before we go into detail let us summarize that a Water dispenser consumes about 3 watts of power when running on a 120v outlet and about 2 watts of power on a 240v outlet.
On the 120v outlets, Water dispensers consume about 0.25 kWh (3 watts x 8 hours = 25 Wh = 0.25 kWh) of electricity per day. This is lower than an electric kettle but higher than electric coffee makers.
On 240v outlets, Water dispenser consumes about 0.17 kWh (2 watts x 8 hours = 16 Wh = 0.17 kWh) of electricity per day. This is comparable to some electric coffee makers and greater than electric kettles.
Why Do Different Voltages Consume More or Less Energy?
The amount of energy a device consumes is dependent upon the voltage or amperage. Higher the voltage you use more will be power consumption by that appliance. We can say, “The higher the voltage used, the more energy consumed”.
An easy way to think about it is voltage is like “pressure” in terms of water flow. The higher the pressure, the more water will flow through a pipe. Similarly, in electricity, the higher voltage or “pressure”, the more electricity can flow through a wire. This increased flow of electrons results in greater power consumption by that appliance.
What Are the Differences Between 120v and 240v Plugs?
Most major appliances (i.e. a refrigerator, a freezer, an oven) have a voltage of 220v (if it runs on a single-phase). Some smaller appliances (i.e. a hairdryer, television) run at 110v (single-phase), while others run at 240v (if they are three-phase). If we have an appliance running on 110v or 120v then we need single-phase power and if the appliance runs on 220v to 240v then we need three-phase power.
Now, let us convert the amperage consumed by a water cooler to a wattage consumed.
In this article, I have tried to summarize how much electricity is used by a dispenser. The amount of energy consumed varies between appliances, but in general, all Appliances consume about 0.25 kWh (3 watts x 8 hours = 25 Wh = 0.25 kWh) of electricity per day. Now, for a 120V plug, the appliance will consume about 0.25 kWh (3 watts x 8 hours = 25 Wh = 0.25 kWh) of electricity per day. If it is running on a 240v outlet then it will consume about 0.17kWh (2 watts x 8 hours = 16 Wh = 0.17kWh) of electricity per day. So, the 120V appliance will require 25 Wh per day on a single-phase outlet and about 16 Wh on a three-phase outlet.
What Does a 240v Power Supply Look Like?
Now, Let us presume we have a 240v plug and discuss the differences between 120v and 240v power supplies. A 240v power supply can give you a maximum of 28 Amps, which is more than double that on 120v outlets (8A).
Maintenance Tips for better performance: Detailed
1) Water level
Check water level regularly to keep your machine running smoothly. Clean and fill with water more often during summer, when the air is drier.
2) Filter cleaning: Change the filter regularly (every 2-3 months) to preserve taste and avoid bacteria growth in the reservoir. If you have a cooler for hot and cold, then clean both of them at once! This will save you time in the future.
3) Faucet cleaning: Every couple of weeks, take the faucet apart and clean it with hot water and soap. Remember to check that the rubber gasket on the faucet is still intact, elastic, and in good condition.
4) Regularly check P-Trap for properly maintaining safety from water overflow.
5) Regularly check the faucet’s screws, nuts, and joints.
6) Use a foaming cleaner to remove mineral deposits and limescale from the dispenser.
7) For the hot water dispenser, check the temperature. Ensure it is high enough, but not too high, by adjusting the thermostat setting. Use a thermometer for precise adjustment. If you have a water dispenser for hot and cold water, make sure the temperature is suitable for both.
8) To prevent calcium build-up in your cooler and dispenser, flush your lines regularly with vinegar. Simply hook up a hose or bucket to one of your water faucets and run the vinegar through until it runs clear.
9) By using hot water, dishwashing detergent to clean the cooling unit. This will remove any hard water buildup that may have accumulated inside the machine.
10) To remove the scale from the water cooler you need to use a water softener. Check with your local supermarket if they have one. Then pour the softener into your machine and run it for at least an hour.
11) Regularly check your dispenser for leaks. Leaks can cause many problems, damage the machine’s internal parts, and eventually lead to failure. Inspect all seams, connections, and faucets inside the machine, also check hose connections on top of it for leaks and replace any damaged parts immediately.
12) Clean the water reservoir at least weekly. This will help you to keep your machine running smoothly and clean. The reservoir can be cleaned by using a solution of water and vinegar, or an odor-reducing cleaner. Rinse the reservoir thoroughly with warm water after cleaning it. If you would like to prolong the life of your water dispenser, inspect it carefully, keep in mind that any damage caused by misuse is not covered under the manufacturer’s warranty.
13) Store the machine in a cool location. Keep it away from direct sunlight or heat sources.
14) If your water dispenser is outside, keep in mind that the amount of water in the machine during winter may freeze when temperatures drop below freezing. To prevent this, empty the reservoir and fill it at least half full with antifreeze to fill up excess space inside and prevent air pockets from forming when the temperature drops below freezing point.
So, that’s how much energy is used by a dispenser. Whenever you feel your machine is working too hard, then simply check the water level and flush with vinegar or running water. If you are not having any of the above problems and your water dispenser is working fine then it’s time to enjoy your cool drink all day long!
