Product Description
The Weil-McLain 672619218710 is a WTGOTM Series 4 hot water oil boiler designed for residential space heating and domestic water heating. This floor-mount unit is built with cast iron sections, giving it the durability and heat retention that HVAC professionals rely on for long-term installations. The boiler operates at 122 MBH input and delivers a Net I=B=R capacity of 126,000 BTU, making it well suited for homes that require a dependable oil-fired heating solution. It is rated at 86% AFUE, which reflects solid fuel-to-heat efficiency for a natural draft oil boiler in this class. The unit comes with a Taco 007e circulator included, simplifying the installation process and reducing the number of additional components a contractor needs to source. Note that the burner is sold separately; compatible options include Carlin, Beckett, and Aiello burners, giving installers flexibility to match the burner to the specific job requirements. The boiler features a quick-open top and a swing-away burner door that provides full combustion chamber access, making inspection, cleaning, and servicing significantly faster. Two flue outlets are positioned on the rear and top of the unit, offering complete venting flexibility to accommodate different installation layouts. The boiler includes a low water cutoff and full water trim as standard equipment. Supply and return pipe connections are both 1.5 inches, and the unit runs on 120V single-phase power. It is ASME certified, CSA certified, and UL listed. The Slate Gray cabinet finish, introduced in 2021, gives the unit a clean, professional appearance. This boiler is Energy Star Qualified when ordered with the optional vent damper kit. Cast iron construction, proven trim components, and thoughtful serviceability features make this unit a strong choice for oil-fired residential boiler replacements and new installations.
