The Hatco FR-4B is a high-quality, commercial-grade water heater designed for demanding kitchen environments. Featuring a durable stainless steel front and a silver-gray hammertone body, this unit is built to withstand the rigors of busy kitchens. With a balanced 3-phase heating system, the FR-4B delivers a continuous flow of precisely heated water, keeping food at safe serving temperatures between 140°F and 190°F (60°C and 88°C). The rugged all-metal construction, advanced safety circuitry, and a five-year stainless tank warranty make this Made-in-USA water heater a reliable and long-lasting workhorse for your kitchen. To ensure optimal performance, the unit must be installed with a perforated water baffle (not included), and the incoming water hardness should not exceed 3 GPG, which may require water treatment.
