      Pairs well with

      A high‑output four‑section cast‑iron oil-fired steam boiler engineered for exceptional reliability, dry‑steam performance, and long service life. The MegaSteam platform is widely regarded as one of the most efficient residential oil-fired steam boiler available, delivering industry‑leading thermal performance with an AFUE rating up to 86%. The MST513SL‑HL arrives as a factory‑packaged unit with burner installed, pre‑configured for clean, stable combustion and natural‑draft chimney venting.

      This model is supplied less tankless coil, making it ideal for homes that use a separate water heater or indirect tank rather than generating domestic hot water from the boiler.

      Key Features
      Four‑section cast‑iron heat exchanger designed specifically for steam production, ensuring dry steam, stable pressure, and long‑term durability.

      Factory‑installed oil burner (Beckett, Carlin, or Riello depending on configuration) tuned for clean, efficient combustion.

      Natural‑draft chimney venting for straightforward replacement of older atmospheric steam boilers.

      Exceptional efficiency with MegaSteam’s industry‑leading thermal design and low standby losses.

      Less tankless coil configuration ideal for systems using a standalone water heater.

      Quiet, low‑vibration operation supported by Burnham’s combustion chamber and block design.

      Service‑friendly layout with accessible burner, controls, and steam trim for easier annual maintenance.

      Ideal Applications
      Homes with one‑pipe or two‑pipe steam systems requiring a high‑capacity, long‑lasting oil‑fired steam boiler with a factory‑matched burner and chimney venting.
