GSW 2-1/4" Water Heater Pressure Relief Valve

Heat pump water heaters absorb ambient heat from the surrounding air to the heat water using a compressor and environmentally friendly R134a refrigerant. These 80 USG/303 L heat pump models have a Uniform Energy Factor (UEF) of 3.45, ensuring this is the most energy-efficient, cost-effective option for consumers who want to save money on their electric utility bills. These models are ideal for basement installations, as the compressor transfers heat to the water while dehumidifying and cooling the ambient air. This model comes with four operating modes to maximize efficiency and performance: Heat Pump, Hybrid, Electric, and Vacation.
