energy efficiency
Most Cmmoercial Water Dispense is constantly opened, which allows you to get hot and cold water at any time. If you don't want to wait for the water to heat up or cool down, look for a water dispenser with an Energy Star rating, which means it is designed to be energy conscious and will not waste energy when it is turned on.
You may not want to use the machine for hot or cold water all the time. For example, if you only want to drink hot water for a cup of tea or coffee in the morning, there are many machines that allow you to turn off the heating function in the afternoon and only run the refrigerator, which will help you reduce energy waste. The same is true for the cooling function.
Temperature characteristics
The basic expectation of Commercial Water Dispense, whether it is a countertop, top loading or bottom loading device, has two temperature options: cold and hot.
The hot ones should be close to boiling and hot enough to be used in hot beverages and instant foods. The cold is usually around 50°F, or 10 degrees below room temperature. Some water coolers also have room temperature water options, but this is not common.
