A hot and cold water dispenser is a convenient and quick device for providing hot and cold water. However, many wonder if it consumes electricity and how to use it efficiently to save power. The following article will explain in detail.
Exploring hot and cold water filters
What is a hot and cold water dispenser?
Hot and cold water dispenser (also known as a hot and cold water purifier) is seen as one of the most convenient household appliances that every family, school, or workplace should have. They have the ability to use a single water source and provide both hot and cold water simultaneously to meet the needs of users. As a result, you can use hot or cold water without having to spend a lot of time boiling it in a kettle or cooling it with ice.

Most hot and cold water purifiers typically come with 2 separate faucets for hot and cold water
Structure of water purifiers
To ensure safety, durability, and energy efficiency, most hot and cold water purifiers on the market today use block technology instead of electronic chips. Depending on the brand and model, this hot and cold water machine will have unique structures. Typically, the machine is made up of components such as:
- Coldness sensor
- Hot/cold water tank
- Wastewater regulation device
- Water inlet head
- DC converter unit
- Electronic valve
- Cooling block
- Pressure boosting pump
- RO filtration system consists of 3 filter cores, RO membrane, and upgrade core, which helps water source to remove harmful substances as it passes through.

Basic design structure of hot and cold water purifiers
Functions of hot and cold water dispensers
- Convenient, immediate use without waiting time.
- Sleek design, does not take up much space in residential or office areas.
- Elegant and sophisticated design suitable for formal spaces like offices and adaptable to any interior design.
- Optimal energy saving as the machine automatically shuts off power when sufficiently cooled or heated, maintaining temperature.
- Safer for young children compared to using hot water kettles or other hot keeping devices in the household.
Classification of hot and cold water dispensers currently available in the market
There are many types of hot and cold water dispensers on the market operating based on different technologies. Among them, 3 common types of technologies used are: block-operated dispensers, chip-operated dispensers, and integrated filtration dispensers.
- Block-operated hot and cold water dispensers
Unlike typical electronic chips, this block technology is mostly applied to water dispensers with energy-saving functions. Specifically, when the product operates, the water will be heated by thermal coils. When the water reaches the ideal temperature, the relay will automatically shut off, and vice versa when the water cools down.
- Chip-operated hot and cold water dispensers
The mechanism of operation of this hot and cold water dispenser will involve lasers trapping or cooling atoms. The operational step then is molecules entering ion traps. And lasers will shine at an appropriate level so that the molecules reach the ideal temperature. From there, both kinetic momentum and temperature decrease accordingly.
- Integrated filtration hot and cold water dispensers
In addition to the above-mentioned technologies, some premium hot and cold water dispensers also come with integrated water filtration functions. This is a product very suitable for households with water sources that do not ensure safety. With different water sources, there will be suitable filters.

Depending on the different technologies in hot and cold water machines, they can help users save energy
Advice on using hot and cold water dispensers: Do they consume electricity?
Do hot and cold water dispensers consume electricity?
Power and operating mechanism are the two main factors that affect the electricity consumption of the product.
- Water dispenser utilizing block technology
With block technology, the machine is equipped with a large capacity heating rod in the hot container, approximately 500W, and is designed with a relay to control water temperature. Thus, if the water temperature is below 90°C, the relay will automatically turn on to heat up the water. Meanwhile, in the cold container, when the water temperature exceeds 10°C, the machine uses a relay to activate the refrigeration compressor again. In this way, the water source is continuously heated and cooled, allowing you to always have water as desired while still saving electricity.
- Devices utilizing electronic chips
These devices are all based on the Doppler principle, and the operating mechanism relies on trapping and cooling atoms or ions. Therefore, the cooling temperature is not deep (only about 10°C) and the heating temperature is not high (reaching about 80°C).

The issue of electricity consumption also depends on the operating power, tank capacity, and power cutoff mechanisms...
Conclusion: Generally, hot and cold water dispensers tend to consume less electricity compared to devices like electric kettles or refrigerators. However, it can be seen that the cooling method using block technology saves more electricity than devices using electronic chip cooling technology. Additionally, the level of electricity consumption is also influenced by many other factors, especially the operating power. The larger the operating power, the higher the electricity consumption.
Electricity-saving technologies in water dispensers
Furthermore, to determine whether a hot and cold water dispenser consumes electricity, it also depends on the filtration mechanism on the machine supporting features with low power consumption. Therefore, when choosing a water dispenser, you should not overlook products with technologies that help save energy.
- Opt for a water dispenser with quality relays, as relays are vital components that aid the device in halting operation when the water temperature reaches the ideal level.
- Prioritize selecting a product that integrates both a 2-in-1 water filtration system and hot and cold water functionality to save both electricity and space.
How to Use Hot and Cold Water Dispensers to Optimize Energy Savings
Compared to before, when using a hot and cold water dispenser, the amount of electricity consumed in your home will undoubtedly increase and change. But fret not, a few small tips below can help you reduce unnecessary electricity consumption:

An important note to save electricity is that when there is no water jug placed on the top, do not plug in the device; moreover, if prolonged, it can cause the machine to short circuit or even explode
- Do not plug in when there is no water jug placed on the top of the machine
- Place the jug on top of the machine about 10 minutes before plugging in to use
- When not using the water dispenser for an extended period, unplug and turn off the electricity
- Avoid placing the device in areas with high temperatures, and keep it away from rain, wind, or direct sunlight
- Avoid sharing power sockets with other devices; instead, use a separate socket for the hot and cold water dispenser
- When cleaning the machine, refrain from using detergents or chemicals that may affect its durability
- To enhance the efficiency of the machine, clean the dust on the heating element regularly
- Regularly clean, maintain, and service the hot and cold water dispenser approximately every 2 - 3 months
