Weil-McLain EGH Series Boiler Key Features & Benefits

The Weil-McLain EGH series boilers are medium capacity cast iron boilers designed with strong and reliable parts to help improve efficiency and reduce heat loss. Each component is meticulously crafted based on the decades of experience of the engineers at Weil-McLain.

Due to the intricately detailed construction, it’s not uncommon for Weil-McLain’s cast iron boilers to last in excess of 40 years and achieve exceptional efficiency throughout its life. In addition to the unparalleled durability, performance, and longevity, each Weil-McLain EGH commercial gas boiler includes an array of standard features:

  1. Combination regulator and gas valve effectively combines all automatic and manual control functions that are required for the hassle-free operation of the boiler. Instead of having various individual main line gas controls and pilot lines, the combination gas and regulator valve replaces them.
  2. Tankless opening eliminates the additional costs of storing large volumes of water in a storage tank, which means the boiler will waste less energy.
  3. Available as a water or steam boiler based on your application and facility needs.
  4. Non-linting pilot burner provides worry-free operation in the process of lighting the primary gas burners and operating the pilot safety shutoff device.
  5. Horizontal to vertical draft hood simplifies connecting the system to the chimney flue.
  6. Factory-assembled section block that saves time as well as works to minimize installation and startup costs.
  7. Insulated extended steel jacket works to reduce heat loss and keep heat in.
  8. Stainless steel burners ensure quiet operation of the boiler and provide a fixed primary air that doesn’t require air adjustments.
  9. Unmatched comfort and reliability based on the decades of experience gained by Weil-McLain engineers and designers.
  10. Burner shield to protect the burner and promote safe and efficient operation.
  11. Electrical junction box simplifies as well as expedites locating, servicing, and repairing any type of electrical problems that may arise.
  12. 40 VA transformer (with receptacle for plug-in relay)
  13. Highest-efficiency model-PI w damper, intermittent electronic ignition, system and automatic vent damper system used to promote reduced fuel consumption.
  14. High-efficiency model-PI intermittent electronic ignition is initiated by an electronic spark and only burns when the heating cycle is ready to begin, which results in significant fuel savings and efficiency gains.
  15. Standard efficiency model (EGH-85 and 95 only) constant burning, thermally supervised pilot system, and thermocouple works to ensure the safe and efficient operation of your boiler.
