Rinnai’s RCW Series commercial boilers are delivering high efficiency water heating performance at 2150 Condos in Toronto, marking the first installation of the RCW750AN floor-standing model in Canada and establishing a field reference for high rise applications where volume, sustainability and operational efficiency are critical.

Located at 2150 Lawrence Avenue East in Toronto’s Scarborough neighbourhood, the multi-tower residential community includes three buildings completed in 2020. The RCW750AN installation specifically serves the 17-storey tower comprising 204 residential suites and shared common areas, placing significant demand on its centralized domestic hot water infrastructure.

Following a heat exchanger failure in 2024 of the tower’s previous boiler system, management elected to proactively replace both units with a long term, higher efficiency solution designed to support both performance and environmental objectives. The upgrade consisted of two RCW750AN floor-standing commercial condensing, gas-fired volume water heaters installed in cascade and paired with a 1,600-gallon (6,056.66L) storage tank to support fluctuating demand.

The RCW750AN is engineered for demanding commercial environments and supports Canadian sustainability priorities through up to 99% thermal efficiency and Ultra Low NOx emissions. A 316L stainless steel heat exchanger enhances durability and long-term reliability, while a 10 to 1 turndown ratio allows the system to closely match building load, reducing unnecessary energy consumption. The system also incorporates Rinnai’s industry first integrated 7-inch (17.78-cm) touchscreen control platform, designed to simplify commissioning, diagnostics, and ongoing monitoring for facility teams and service professionals.

“This project shows exactly what the RCW Series is designed to do: deliver reliable, high efficiency performance in demanding conditions,” said Daniel Zrubak, general manager, Rinnai Canada. “From Canada’s extreme winter temperatures to year-round high-rise demand, our water heaters are engineered with the latest technology to serve this market. We support our PRO partners every step of the way, and that support and commitment is how we exceed expectations while continuing to create a healthier way of living in all types of residential and commercial applications.”

High rise boiler replacements often require crane lifts to position equipment in upper mechanical rooms. At 2150 Condos, that step was not necessary. The RCW750AN factory integrated castors allowed the mechanical contractor to roll the boilers through the building and at only 28.5-inches wide (72.39 cm), transport them via elevator to the penthouse mechanical room. Removable doors and integrated lifting hooks, locking casters and leveling feet further simplified handling and positioning. 

Rinnai commercial sales and engineering personnel were present onsite during startup to support commissioning and verify combustion performance. During initial operation, one boiler independently carried the overnight domestic hot water load. Once fully cascaded, the system modulated effectively with system sensor control, delivering stable and efficient performance across varying demand conditions.

“The boilers have been running smoothly with no issues,” said Akram Ziad, condominium manager at 2150 Condos. “Our HVAC provider monitors the system monthly and reports strong performance. We have not received resident complaints regarding hot water, and we are seeing encouraging trends in operating performance compared to the previous system.”
