Product Description
The Weil-McLain 672619218550 is a WGOTM Series 4 cast iron hot water oil boiler designed for residential floor-mount installations. This unit delivers 98 MBH input and is rated at 86.2% AFUE, making it a reliable and efficient choice for oil-fired hydronic heating systems. The boiler is built with durable cast iron sections that hold heat well and stand up to years of demanding use. It is a dedicated water-only unit, meaning it does not include a tankless heater or cover plate, keeping the design straightforward for heating professionals who need a clean, serviceable install.
Access and serviceability are central to the WGOTM Series 4 design. A quick-open top and swing-away burner door provide full combustion chamber access, so technicians can inspect and service the unit with minimal downtime. A recessed target wall protects the interior from damage caused by flue brushes during cleaning. Two flue outlets located on the rear and top give installers complete venting flexibility to work within a wide range of mechanical room layouts. The boiler ships with a low water cutoff and full water trim already included, reducing the need for additional components at installation.
The burner is sold separately. Compatible burners include Carlin, Beckett, and Aiello models, giving HVAC contractors the flexibility to match the burner to the job requirements. The unit is AHRI Certified and CSA Certified, and carries a Net I=B=R Capacity of 100,000 BTU. It operates on 120V single-phase power and connects to 1.5-inch supply and return piping. Dimensions measure approximately 35.625 inches in height, 20.25 inches in width, and 16.875 inches in depth. The unit vents via natural draft and is built to ASME standards. With its Slate Gray finish introduced in 2021, this boiler is a proven solution for residential oil heating replacement and new installation projects.
