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. 

The MagnaTherm HTD series of condensing boilers and volume water heaters boasts real time O2 trim compensation that maintains ideal air-to-fuel ratios, full 20:1 turndown on all sizes to match varying load profiles and the Laars Linc icon-driven control system.

The owner asked for a bid to replace her 35-year-old cast iron boiler which was still operating. She had two requirements: Redundancy in the event of a boiler malfunction and lower fuel costs for the building.

When John Kopf eventually gets around to designing and building his own house, he will go with hydronic heat instead of a more traditional forced air system. Kopf knows a thing or two about heating, having spent more than 20 years in the industry. He currently serves as boiler product manager for Navien.

The MACH® condensing boiler from Patterson-Kelley increases turndown, with emphasis on system efficiency, reliability and serviceability.

AERCO’s Benchmark Platinum condensing boilers with the Edge Controller saves time and money on installation and operating costs, simplifies start-ups and maintenance and strengthens system efficiency and performance, the company notes.

Navien NFB series high-efficiency condensing fire tube boilers are available in two models, NFB-175 (175,000 Btu/h) and NFB-200 (199,900 Btu/h).

The Bosch Greenstar is the world’s best-selling residential condensing boiler system, the company notes.

Triangle Tube’s Instinct stainless-steel fire tube heat exchanger is manufactured and produced to the highest quality standards to ensure reliability, the company says.

The Instinct is offered in combi and solo models.
