About this model

The EGH Series 5 is a cast-iron, gas-fired steam boiler. Every size is a steam boiler: it boils water and sends steam up to the radiators through the building’s steam piping, with no circulator pump. A hot-water (hydronic) boiler instead pumps heated water through baseboard, radiators or floor tubing. The two systems are not interchangeable, so an EGH can only be replaced by a boiler rated for steam.

It is a heating-only boiler. It does not make domestic hot water on its own: Weil-McLain offered an optional tankless coil rated 3.0 to 3.25 GPM intermittent, and otherwise hot water comes from a separate water heater. A combi boiler heats the building and makes domestic hot water in one appliance, and a tankless water heater makes hot water only; the EGH is neither.

Weil-McLain listed the EGH in its commercial line, and both residential and commercial warranty documents were issued for it. It burns natural gas or propane (propane with a conversion kit) and vents through an atmospheric draft hood into a chimney, with an optional vent damper. That is the conventional non-condensing cast-iron design: the flue gases stay hot and rise up the chimney. A condensing boiler, by contrast, uses a stainless steel or aluminum heat exchanger, cools the exhaust until water condenses out of it, vents through PVC or polypropylene pipe out a sidewall and needs a condensate drain, which is why it reaches 90% AFUE and higher and can sit in more locations. AFUE is the share of the fuel that becomes heat for the building over a heating season; Weil-McLain does not publish an AFUE for the EGH on any current source, so none is stated here.

Cast-iron sections are the bolted-together iron chambers that hold the boiler water. They tolerate the high temperatures of a steam system and give this type of boiler a long service life, although a leaking section usually means the boiler is at the end of its life. Series 5 units use a spark-ignited intermittent pilot; older EGH units had a standing pilot.

Published outputs

Model	Steam output (lb/hr)
EGH-85	253
EGH-95	290
EGH-105	325
EGH-115	361
EGH-125	398

Source: Weil-McLain EGH Boiler Manual. The EGH-85 gross output is 243 MBH (MBH means thousand BTU per hour).

Input ratings, net ratings, AFUE and dimensions by size are not stated here because they are not available from a readable current manufacturer source; see the manufacturer’s product data or your boiler’s rating plate. Input is the gas the boiler burns; the net rating is the heat actually delivered to the radiators after piping and pickup losses, and a replacement is sized against the building’s heat loss, not the old nameplate.

Repair and service for this model

A discontinued boiler does not automatically need to be replaced. GSHA Services, LTD services and repairs existing Weil-McLain boilers, and Weil-McLain still lists the EGH in its parts catalog; availability of a specific part is confirmed at the time of repair. Because the EGH is a commercial steam boiler, tell us the model and whether it serves a home or a commercial building when you call, and we will confirm whether we can service it before the visit is scheduled. Repair is diagnosed on site; there is no flat rate for a specific fault.

An annual tune-up matters on a chimney-vented cast-iron boiler: it checks combustion and draft, the low-water cutoff and the other safety controls, and catches small problems before the heating season.

Current alternative

Weil-McLain has not named a successor to the EGH, so no model on this page is called a direct replacement. In Weil-McLain’s current lineup the EGH sat between the residential EG line and the commercial LGB line, which is why GSHA suggests these two as the starting points:

• Weil-McLain EG Series 7: a cast-iron, chimney-vented boiler rated for water or steam in every size, 75,000 to 282,000 BTU/h input (EG-30 to EG-75), with the PEG packaged steam version in sizes 30 to 65. Comparable because it is the same cast-iron atmospheric design and is rated for steam.
• Weil-McLain LGB commercial cast-iron boilers: LGB Series 2 from 400 MBH input and the LGB High Efficiency Series 3 from 350 MBH input, steam or water in every size. Comparable for steam loads above the EG range.

Which one, and which size, depends on the building’s heating system (the EGH is steam, so the replacement must be rated for steam), the fuel, a heat-loss calculation of the building, the chimney condition and the piping, gas line and electrical requirements. The free on-site estimate settles it. The installation scope GSHA publishes is written for hot-water systems; when you request an estimate for a steam replacement, we will tell you whether and how we can quote it. No installed price is published for either alternative: installed price after a free on-site estimate. Financing available with approved credit; see financing.

Frequently asked questions

Do you install and repair Weil-McLain boilers in my city?

Yes, if you are in McHenry County or Lake County, Illinois, the northern and western Chicago suburbs or southeastern Wisconsin. GSHA Services, LTD installs, services and repairs Weil-McLain boilers from Woodstock and Lake Bluff, Illinois; check our service area page for the city and ZIP list.

Can my existing or discontinued Weil-McLain boiler be repaired?

GSHA Services, LTD repairs existing Weil-McLain boilers, and Weil-McLain still lists EGH parts in its catalog. For a discontinued commercial steam boiler like the EGH, tell us the model and the building when you call and we will confirm whether we can service it; a technician then confirms on site whether the unit can be repaired and whether the part is available. A discontinued model does not have to be replaced while it is safe and serviceable.

What is the difference between a combi boiler and a heating-only boiler?

A combi boiler heats the building and makes domestic hot water in one appliance. The EGH is a heating-only steam boiler: hot water comes from a separate water heater or, on units so equipped, an optional tankless coil. A tankless water heater makes hot water only and does not heat the building.

Is this boiler for steam or hot-water heating?

Steam only, in all five sizes. A steam boiler boils water and sends steam to the radiators; a hot-water boiler pumps heated water through the system. The EGH cannot be used on a hot-water system, and a hot-water boiler cannot replace it on steam piping.

What does a replacement installation include and what can change the price?

There is no set price: a replacement is quoted as an installed price after a free on-site estimate, because every boiler installation is custom and GSHA’s published installation scope is written for hot-water systems. Chimney and venting condition (a liner if needed), steam or hot-water near-boiler piping, gas line capacity, electrical work, water-quality treatment, removal of the old boiler, permits and accessories (priced separately) all differ from building to building and change the final price.

When does repair make more sense than replacement?

Repair usually makes sense when the cast-iron sections are sound, the fault is a single part such as a control, gas valve, pilot or low-water cutoff, and the part is available. Replacement makes more sense when a section leaks, repairs are recurring, parts are hard to get, or a safety problem with venting or combustion cannot be corrected. We give you both options after inspecting the boiler.

What replaces the Weil-McLain EGH?

Weil-McLain has not named a successor. GSHA suggests the EG Series 7 (rated for water or steam, up to 282,000 BTU/h input) for smaller steam systems and the LGB commercial line for larger loads as the current starting points; the right model and size are settled by a heat-loss calculation at the free on-site estimate.
