This Boiler is a Weil-McLain Model 84 Commercial grade natural gas fired product, which is extremely durable, with a normal service life of 90 years.
Weil-McLain continues to manufacture nearly identical Boilers at its Burlington, Ontario plant today.
This Boiler contains a modular cast iron 3 pass heat exchanger, which operates at 80 percent efficiency.
This Boiler is over-sized for its current application, because it predates the 1972 addition at 958 Broadview, which reduced the building exterior wall and window area by 25 to 30%.
Products are available today to provide better occupant comfort and temperature control for this Steam Boiler, which we can discuss further.
