For cafes, offices, or anyone who needs to keep coffee hot for a crowd, this Waring Commercial double warmer is a pro. It has two separate warming plates, each with its own on/off rocker switch, so you can use one or both at the same time. Just plop your coffee carafes or pots on there, press the switch, and it keeps them at the perfect serving temperature without burning. It's built like a tank from easy-to-clean stainless steel. It's lightweight and portable, with non-skid feet so it stays put on the counter. Plug it into a standard 120V outlet (5-15 plug). It's NSF certified and TÜV Rheinland approved, which is what you want for commercial use. Perfect for diners, break rooms, catering events, or church functions. Never serve lukewarm coffee again!
