Features
    Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing lasting heating solutions is seen in every boiler they make. The EG is one of Weil-McLain's most versatile natural draft boilers. It is available in natural gas or liquid propane for both hot water and steam applications. The EG-55-S-PIDN is a natural gas steam boiler with Annual Fuel Utilization Efficiency of 82.8% AFUE. The EG is well suited for new construction, and it makes an excellent replacement boiler as well. Weil-McLain has used cast-iron for the EG's heat exchanger, a material known for its long life. The blend of durability, efficiency, and versatility in the EG makes it an attractive boiler for all systems.
  • Venting Improvements
  • By utilizing a horizontal-to-vertical draft hood, Weil-McLain has avoided the need for bulky traditional draft hoods. An included automatic vent damper provides ideal combustion conditions to reduce fuel use and improve efficiency.
  • Efficiency-Boosting Insulation
  • Heat retention is critical to energy efficiency. Heat leakage represents energy use without any comfort gains. An extended, insulated steel jacket prevents heat from escaping the EG and improves the efficiency.

Does it come in one piece so that all I do is just hooking up?
Po B. 
from New York 
October 25, 2016
Answer
This is a knockdown boiler the requires on-site assembly assembled. Weil-McLain offers select models within the EG-Series in a packaged version that requires only limited on-site assembly.

What is the difference between the EG-65-S-PIDN-T and EG-65-S-PIDN?
Earl 
from New York 
December 18, 2015
Answer
The '-T' at the end of some EG-Series model numbers indicates that the boiler is configured to accept a tankless domestic hot coil. This coil will allow you to use heat from the boiler to heat water for domestic use, but will also require that your boiler remain hot at all times, resulting in higher energy use. Be aware that the '-T' only indicates that the boiler as the necessary openings to allow installation of the coil, and the coil must be purchased separately. Models without the '-T' cannot use the tankless coil.
