These dispensers are connected to a central heater, such as supplying boiling water to your home or office.

The advantage of this type of dispenser is that it can provide a continuous water supply, which is ideal for high-volume use.

Centralized heater dispensers typically use between 1000-and 1200 watts of power.

 On-demand water heater dispensers:

These dispensers have an internal heating element that heats water on demand. They do not require a connection to a central heater.

On-demand dispensers are well suited for low-volume use, as they only heat the water that is needed at the time.

On-demand heater dispensers typically use between 1200-and 1500 watts of power.

Energy efficiency:

When choosing an instant hot water dispenser, it is also essential to consider electricity efficiency.

Centralized water heater dispensers are usually more energy-efficient than on-demand units. They do not have to heat water constantly.

However, on-demand dispensers can be more efficient than electric kettles and other tools that require users to heat the water separately.

Overall, an instant hot water tank will depend on your individual needs and usage patterns.

Whether you need a high-volume hot tap water supply or prefer a low-energy option, an instant boiling water dispenser can meet your needs.​

How to Reduce The Energy Consumption Of A Dispenser? 

1. Bring water to a boil only when necessary.

If you need water for making the hot beverage, tea, coffee, or instant soups, bring a pot of water to a boil on the stove instead of using the dispenser.

2. Keep the unit clean. A dirty water cooler can use up to 50% more energy than a clean one.

3. Use a power strip and plug the dispenser into it. When not in use, switch off the power strip to cut all power to the unit.

4. If your cooler has a hot water tank faucet, only turn it on when needed.

The same goes for the cold water – only have it on when you’re filling a cup or pitcher.

5. Adjust the thermostat on your cooler to the appropriate setting for your needs.

If the water is too cold, increase the water temperature slightly; decrease it somewhat if it’s too hot.
