How to choose
Match temperatures to your drinks
A cooler with a heater should cover both ends: hot water for drinks and instant meals, and cold water for drinking. The Giantex gives hot and cold water with separate stop switches, the Primo gives 3 temperatures with touch controls, and the GE gives hot and cold water through push-button controls. Compare the stated temperature ranges: the Primo cools to 39.2 degrees and heats to at least 188.5 degrees, while the GE chills from 40 to 50 degrees and heats from 165 to 190 degrees.
Check tank sizes and flow rates
Tank size sets how much hot or cold water is ready at once. The Primo has a 3-liter cold tank and a 1-liter hot tank, while the GE gives hot water at up to 5 liters per hour and cold water at up to 3.5 liters per hour. Bottle size matters too: each pick here works with 5 gallon bottles, and the Primo also takes 3 gallon bottles. Match the tank and the bottle to how many drinks you make in a row.
Set up and daily upkeep
Top-loading models need the bottle lifted onto the top, so place the unit where the bottle can be set down close by. A detachable barrel seat, like the one on the Giantex, comes apart for cleaning. The Primo has a removable drip tray that lifts out for washing. Wipe the outside with a damp cloth and keep the area around the taps dry between uses.
