A hot water beverage maker uses a voltage transformer type heating unit to heat water flowing to the filtering vessel. The water flows from a water reservoir to a wound transformer where the water passes through metal tubing that is also the secondary winding of the transformer. The secondary winding is shorted. The water to be heated then flows to the filtering vessel that may contain coffee or tea. The water flows through the filtering vessel to a carafe for serving.
