The Peerless® Partner® Lo-Boy indirect-fired water heater provides a true advancement in hot water generation. By utilizing the existing boiler as its heat source, the burner fires only when necessary and transfers heat energy through a highly efficient cupronickel, fin-tube heat exchanger. The heater functions as a separate heating zone and water movement is regulated from the boiler through the heater coil by a separate circulator or zone valve. Learn More
