1. Wattage

The overall power consumption of any hot water dispenser depends on the wattage rating. Wattage gives us an idea of the maximum power consumed by the dispenser.

Similarly, a 2000 Watts dispenser will deliver 2000 Watts of energy. A higher wattage dispenser will thereby take less time to heat water since it is allowing maximum energy conversion. Depending on the overall water volume, a hot water dispenser with suitable wattage can be chosen.
