The Voltex® Hybrid Electric Heat Pump reduces water heating cost by up to 71% through an innovative design that pulls environmental heat while dehumidifying and cooling the ambient air at the same time. The FPTU-50 uses heat pump technology to deliver tremendous savings, by generating heat through the heat pump technology instead of the heating elements. It offers premium features including a user-friendly display, vacation mode to save money while you are away, and a heavy duty anode that protects your tank for 6 years. In addition to the heat pump technology, this model also has two heating elements that help the water heater recover quickly during periods of high demand.
