It delivers 122 MBH input and 115,000 BTU heat output, making it a reliable choice for whole-home space heating and domestic water heating. The boiler is a water-only, oil-fired unit built with durable cast iron sections that hold heat efficiently and stand up to years of heavy use. HVAC technicians and heating contractors rely on this type of cast iron oil boiler for its long service life and straightforward maintenance access. The unit includes a Taco 007e circulator pump, which moves heated water through the hydronic distribution system efficiently. The burner is sold separately, with compatibility for Carlin, Beckett, or Aiello oil burners, giving installers the flexibility to match the burner to the job. A quick-open top and swing-away burner door provide full combustion chamber access, which speeds up annual cleanings, inspections, and service calls. Two rear and top flue outlets give installers complete venting flexibility to work with existing chimney configurations or new natural draft vent setups. The recessed target wall design protects internal components from flue brushes during routine chimney cleaning. The unit ships in the new Slate Gray color introduced in 2021. It includes low water cutoff (LWCO) protection and a full water trim package, meeting standard residential boiler safety requirements. The boiler carries ASME certification, CSA certification, and UL listing, confirming it meets recognized safety and performance standards. Single-phase 120V electrical connection is required. Supply pipe connection is 1.5 inches and return pipe connection is 1.25 inches. The unit measures approximately 35.625 inches tall, 20.25 inches wide, and 13.75 inches deep. This boiler is a proven solution for residential oil-fired hydronic heating systems where dependability and service access matter.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCast iron sections for long-lasting heat retention and durability in residential oil-fired hydronic heating systems\u003c\/li\u003e\n\u003cli\u003eQuick-open top and swing-away burner door allow full combustion chamber access for faster inspections and service\u003c\/li\u003e\n\u003cli\u003eTwo rear and top flue outlets provide complete natural draft venting flexibility for new or existing installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Weil-McLain WTGOTM Series 4 delivers 122 MBH input and 115,000 BTU output in a cast iron floor-mount oil boiler with a Taco 007e circulator, full water trim, and LWCO protection included.
