Coming from the Bunn-O-Matic Corporation is the BTX thermal carafe brewer. What makes the Bunn stand out from the crowd is the fact that it has a water reservoir on board, where water is preheated to 200°. The water is then released quickly over the brew basket resulting in a ten-cup pot in just about three minutes! As the BTX has a thermal carafe it doesn’t need a strong hotplate — it has a coffee-warming hotplate that is heated by its own 34-watt element, independent from the heater for brewing water.
