Peerless Boilers 103001 Cast Iron Hot Water Boiler 70K Btu

Product Description

The PEERLESS BOILERS 103001 is a packaged cast iron hot water boiler fueled by natural gas, designed for residential and light commercial hydronic heating systems. Rated at 70,000 BTU/h input and 84% AFUE, this boiler delivers consistent, efficient heat output. It ships as a complete water-packaged unit, including spark ignition, a vent damper, and a circulator pump, reducing field assembly time. Licensed HVAC technicians and plumbers install this boiler as a standalone heating plant or as a replacement in existing forced hot water systems.

This boiler is built for natural gas-fired hydronic heating applications. The water-packaged configuration means the circulator pump and damper arrive factory-installed, making it well suited for residential retrofits and new construction where a complete, ready-to-connect heating plant is specified. The cast iron heat exchanger provides durable long-term performance in wet-base boiler configurations typical of baseboard and radiator distribution systems.
