Water dispenser HotFrost D115

Usually, water dispensers allow users to fill a container with both hot and cold water. However, some models, in addition to hot and cold water, also provide room-temperature* water. *Room temperature water will only remain at room temperature if it is dispensed regularly (i.e., if users frequently drink this type of water). Otherwise, in dispensers with compressor cooling, this water may become slightly cool, while in models with thermoelectric cooling, it may become slightly warm. This feature is due to the internal arrangement of the cooling and heating elements in the dispenser. In some models without a cooling function, only hot and room-temperature water is available.

Water dispensers with compressor cooling (similar to a household refrigerator) are more powerful and can cool water to below 10°C. Thermoelectric cooling uses a thermoelectric module based on the Peltier effect. Thermoelectric systems are less powerful than compressor systems. The cold water temperature is typically 12–15°C below room temperature.

Water dispensers are available with three bottle loading types: top loading, bottom loading, and external bottle connection. Top loading is the standard configuration, where the water bottle is placed on top of the dispenser. Bottom loading is a more modern design featuring a dedicated compartment inside the cabinet. The bottle is hidden within the unit, making replacement easier and more convenient. With an external bottle configuration, the bottle is placed separately from the dispenser and connected via a flexible hose.
