Heating the Faithful: A Success Story of Comfort and Efficiency

St. Paul Catholic Church in Valparaiso, Ind., took a significant step towards heating modernization by installing three state-of-the-art Weil-McLain Stainless Steel Vertical (SVF) 725 boiler units. G.L. Jorgensen Heating & Cooling, the installation contractor, played a pivotal role in the hydronic heating replacement project.

For over four decades, Loretta Oswald’s home in Bath, Penn., has been powered by a Weil-McLain oil-fired hot water boiler, a testament to the brand’s unwavering durability and performance. Loretta, a former owner of Oswald Catering & Bakery Services, shares a remarkable tale of how her Weil-McLain unit stood as a steadfast companion through both residential living and a bustling commercial bakery and catering business.

A multi-story office building in Ontario sought to upgrade its two-stage boiler and replace its direct-fired water heater to eliminate short cycling, improve efficiency and provide heating redundancy. Four high-efficiency boilers and one stainless steel indirect-fired water heater from Weil-McLain Canada provided the remedy needed.

When Pine Valley Ranch in Spencerville, Ohio needed a consistent source of hot water to wash 600 cases of eggs an hour, they selected six Weil-McLain SlimFit 750 commercial high-efficiency hot water boilers.

SlimFit boilers have been serving the heating industry since 2009 with rugged, cast horizontal heat exchanger sections that provide thermal efficiencies up to 95.8% (SlimFit 1000 & 1500 models). Large water passageways make them ideal for commercial boiler retrofit applications where the water systems may not be in like new condition.    

A construction project in Calgary, Canada, called Cube, features several firsts. It’s the city’s first office-to-residential space conversion and real estate developer Strategic Group’s first re-purposing project. It’s also the first building in Canada to feature the latest advancement in condensing boiler heating technology from Weil-McLain. 

With a rapidly failing water heater, and an old, inefficient boiler, a 20-unit condominium building in Chicago required major upgrades to its heating system. High efficiency condensing boilers and indirect-fired water heaters from Weil-McLain provided the remedy needed.

“Our water heater was deteriorating rapidly and our boiler very old and inefficient,” said Mike Nowak, president of the board for the Belmont Harbor Condominium, a three story, 20-unit building on Chicago’s north side.
