The hot water dispenser is a reasonably common appliance in households. It can be found in many different homes, both new and old. It’s used to heat hot water, then dispensed into a basin or tub for bathing. A lot of people are concerned about the amount of electricity that their household appliances use.

Electricity Consumption of a Hot Water Dispenser:

Although a hot water dispenser does consume a fair amount of electricity, it’s not as much as one might think. There are many different models of hot water dispensers. These models range from older models to new, more energy-efficient models made today. Older models may use up to 1100W of electricity, which is a significant amount. Newer models, on the other hand, only use around 700W of electricity. 

If you compare this to the energy used by an electric heater, the hot water dispenser’s energy consumption is relatively small. The average energy consumption of an electric heater is approximately 3kWh per day. Hot water dispensers use 60-80% less energy than electric heaters.

The amount of electricity used by a hot water dispenser depends on the quantity and temperature of the water being dispensed. The higher the temperature and quantity, the more electricity will be used. This is because warmer water requires more energy to warm it up than cold water.

If the hot water dispenser is used several times per day, the cost of using it can be pretty high. However, this cost can easily be recovered by using a hot water dispenser instead of an electric heater. As a result, a hot water dispenser is more economical than an electric heater in terms of total annual energy costs.

The size and temperature of the tank in which the hot water is stored also affect how much energy it consumes. The larger the tank, the colder it must be to keep water at a constant temperature. As the water temperature in the tank rises, it requires more electricity to maintain its temperature.

Although a hot water dispenser does use a lot of electricity, it can still be considered an efficient appliance. Once its energy efficiency is factored in, the hot water dispenser is one of the most energy-efficient appliances on any given day. The average annual energy consumption for an electric heater is approximately 7kWh per day.

Newer hot water dispensers are much more energy-efficient than older models because they have better insulation and more advanced features. Hot water dispensers also consume less electricity if the power supply is 220V instead of 110V.

How Can You Reduce the Amount of Electricity Used by Your Hot Water Dispenser?

Try filling the tank with cold water first, then turn on the dispenser to fill it up with hot water. This will help to reduce the length of time that it takes for the water to heat up.

If you use the hot water dispenser to heat water for bathing, try using it during off-peak times. The water heaters in your area will use less electricity if they are not running constantly.

If you have a large family, try getting a hot water dispenser that can hold more water. This will prevent you from having to heat the water more than once.

Disadvantages of a Hot water dispenser:

If you decide to purchase a hot water dispenser, you must remember that they are quite bulky and easily moved. People who have a small home or a home that uses a lot of natural light may not want to get a hot water dispenser. They will need someplace relatively dark to store it in during the day.

If you have children, be sure to keep them away from the hot water dispenser. It can cause severe burns if it is not properly maintained or monitored by an adult.

Using Hot Water Dispensers as a Heat Source:

Hot water dispensers are not used as a heat source with any regularity, but it is possible. The only real purpose of the hot water would be for bathing purposes.

If you want to make hot water dispensers more commonly used as heat sources, you should look into alternative sources that are safe and energy-efficient.

Hot water dispensers are an efficient way to heat hot water for bathing purposes. They use significantly less electricity than electric heaters. The only disadvantages of using hot water dispensers are that they are heavy to move from one place to another and can cause burns when misused.


Q1. How many liters of hot water will be dispensed in each hot water dispenser?
The heated water in the tank depends on two factors, the amount of hot water that is stored in the tank and the temperature that is required to heat this water. Under normal conditions, a full tank will hold approximately 14.5 liters of liquid at 40 C (104 F) and 80% humidity.

Q2. How high does the water in the tank need to be before it heats up?
When filling the tank with water, make sure that you do not overfill it. Overfilling can lead to damage to the heating element and increase energy consumption. Also, do not fill the tank with tap water; use only hot water that has been preheated by boiling or steaming.

Q3. How long does the tank need to be preheated?
The water in the tank needs to be heated for approximately 5 minutes before the dispenser is ready to use. Heating the tank more than once can damage the hot water dispenser or reduce its energy efficiency.

Q4. Can you use an electric heater as a hot water dispenser?
You can use an electric heater as a hot water dispenser; however, the amount of electricity that it uses will depend on its power consumption and heating capacity.

Q5: How often should I change the hot water dispenser?
It would be best if you replace a hot water dispenser every two years. It’s not a hard job, so that you can do it yourself.
