Meets New US Department of Energy Regulations with Enhanced Boiler Efficiencies

Hydronic comfort heating leader Weil-McLain^® has announced the availability of its 2023 Department of Energy (DOE)-compliant commercial cast iron product portfolio with enhanced boiler efficiencies. The upgraded designs of the LGB Steam/Water Series 3 and 88 Water Series 3 boiler product lines include exciting new features that go beyond just regulatory compliance and pave the way for the next generation of industry-leading performance, reliability and service life.

DOE regulation 431.87 states that commercial boilers manufactured after January 9, 2023, including knockdown, assembled block and complete package configurations, must meet higher minimum efficiency standards. The LGB family meets those requirements with enhanced thermal efficiencies up to 84% and combustion efficiencies up to 81%. Additionally, the 88 product family is 2023 DOE-compliant with thermal efficiencies up to 87% and combustion efficiencies up to 88%.

“Weil-McLain is proud to lead the industry in meeting the minimum higher efficiency requirements as the first to offer its complete DOE-compliant portfolio to market” said John Miller, commercial boiler product manager with Weil-McLain. “Increasing the efficiency of the LGB and 88 Water families results in lower fuel consumption and operating costs while providing reliable and trouble-free operation for property owners and facility managers.”

Ideal for light commercial applications such as multi-family, municipal, elementary and higher education, religious and institutional settings, the LGB is Weil-McLain’s highest efficiency commercial cast iron atmospheric gas boiler and is available in steam and water heating designs ranging from 350-2470 MBH. Tested for 80 psi working pressure, the boiler includes factory-assembled bases and natural draft burners for quick and easy installation and features an improved plug-and-play wiring approach, easy start-up programming prompts and an LCD backlit digital display. An exhaust gas draft inducer reduces overhead height requirements and enables a compact boiler installation, allowing for more piping and venting headroom.

The 88 Series family offers a performance range of 960-5845 MBH and is suited for many of the same commercial applications as the LGB line. Available in steam or water boiler configurations with gas, oil and gas-oil fuel options from a broad range of power burner vendors, standard features include a combination pressure and temperature gauge, HXT-bars for optimized heat transfer, low-water cutoff, 30 psi working pressure and observation ports at the front and back for quick inspection without having to disrupt heating system operation.

“In addition to these updates, customers can also anticipate a DOE-compliant 94 Steam Series 4 boiler model targeted for a mid-year 2023 production launch”, added Miller.

The two new products are part of ADEY’s Best Practice^® approach to prolonging the life and efficiency of hydronic heating systems.

ADEY, a U.K- based company whose pioneering MagnaClean CMX® range was recently rolled out in the United States and Canada, is introducing a line of innovative, concentrated system treatment formulas, designed to clean and protect older hydronic heating systems and retrofit installs. MC5™ Cleaner and MC40+™ De-scaler serve different purposes, but both were created to combat a frequently overlooked enemy of untreated hydronic heating systems – black sludge.

The MC40+ Hydronic Heating System Cleaner & De-scaler is a high-strength powdered chemical, specially designed to restore existing boiler systems by removing lime-scale deposits, calcium and magnetite. Rapid-performing MC40+ delivers an advanced clean, with a highly concentrated formula, in as little as one hour. It even comes with neutralizer packets to provide extra peace of mind if there is concern over residues being left in the system.

The second, MC5 Hydronic RAPIDFLUSH System Cleaner, is a high-performance, advanced-strength product, designed to work with ADEY’s award-winning MagnaCleanse® flushing unit. Together, they effectively remove sludge, debris, and scale while delivering exceptional cleaning results quickly.

Key features summary

MC40+:

• Specifically designed to remove heavy lime-scale and calcium deposits from older systems with known water-quality issues or plugged components, such as heat exchangers.
• Preferred option to clean and drain the system quickly.
• Faster-acting, with a working time range of one to four hours.
• Residential only – treats 33 gallons.

MC5:

• Designed for flushing; works best with ADEY’s MagnaCleanse flushing unit.
• Faster-acting than the MC3+® but provides more time than the MC40+. Whether old or new, if the system is to be flushed on the same day that it is cleaned, this is the preferred cleaner option.
• Working time range: from a minimum of 1 hour to a maximum of 7 days.
• Residential size only, treating 26 gallons.
