Heating Power 550W Bottom Load Water Dispenser

The hot water tank is constructed from 304 food‑grade stainless steel with a smooth inner surface that resists scaling and bacterial adhesion. A 550 W heating coil brings the water to 85–95 °C at a rate of 5 liters per hour. Two independent protection devices—a mechanical float switch and an electronic thermostat—monitor water level and temperature. If the level drops below the safe minimum or the temperature exceeds the upper threshold, the heating circuit is cut off. This dual‑layer approach prevents dry‑burning damage and extends the service life of the heating element.

The compressor cooling system operates on a separate thermostat, delivering cold water at 5–10 °C. Because the hot and cold circuits are isolated, heavy use of one function does not affect the other. The warm water faucet draws from an unheated reservoir, supplying water at near room temperature.

The water bottle is stored in a lower cabinet behind a removable front panel. A small internal pump transfers water to the upper tanks when needed; the pump runs for a few seconds per refill cycle. Because the bottle remains at floor level, replacement does not require lifting a full bottle above the shoulders, which makes the unit accessible for elderly users or those with limited upper‑body strength.

Dispensing is controlled by three piano‑key style buttons, each dedicated to one water temperature. The keys are labelled and provide tactile feedback when pressed. The hot water key incorporates a child safety lock: a separate sliding tab must be moved before the key can be depressed, preventing accidental activation. The cold and warm keys operate with a simple push. This design reduces the number of moving parts compared to push‑lever faucets, as each key actuates a direct mechanical valve.

The cabinet accepts standard 3‑gallon and 5‑gallon bottles with a 55 mm crown cap. No adapter is needed. A small LED indicator on the front panel lights up when the bottle is nearly empty, prompting a replacement. The drip tray underneath the faucets is detachable and can be rinsed under running water. The overall unit height (1060 mm) positions the dispensing keys at a comfortable level for most adults, and the top surface can be used to place cups or a small tray.
