Heating equipment must be installed, commissioned, and serviced by a licensed and qualified professional in accordance with manufacturer instructions, applicable codes, and industry standards. Manufacturers do not accept warranty or technical support requests from homeowners or unlicensed individuals. All warranty and technical inquiries must be initiated by the licensed professional responsible for the installation.

Conservationist high efficiency gas boilers are designed for indoor use in installations requiring higher inputs (up to 670,000 Btu). They are rust-proof because water comes in contact with nothing but copper, brass or bronze. These Conservationist models feature a patented burner design that maximizes combustion efficiency. A. O. Smith offers the largest commercial product selection available, including the most specified commercial unit in the U.S. We offer more than 500 different commercial models, including gas fired, oil-fired and electric configurations, ranging in capacities from 5 to 10,000 gallons, with input range from 50,000 BTU to the equivalent of 4,000,000 BTU. Our comprehensive line is the natural fit for spec jobs requiring everything from the smallest commercial installation up to the largest multi-structure complex.

Features:

Unique copper coil combustion chamber captures and maintains heat, delivering efficient hot water

Compact, horizontal heat exchanger design encircles the burner with a combustion chamber that is a 360° wall of copper fin tubes for maximum efficiency

Approved for installation on combustible floors as shipped from factory

Slow opening redundant gas valves ensure smooth light-off without flame roll-out or pilot outage

Patented thermal balancer delays pump shut off at end of heating cycle to remove usable heat from the heat exchanger and reduces scale formation
