Laars FT Series – Commercial

The FT Series Commercial Boiler is a high-efficiency, stainless steel fire-tube system engineered for demanding commercial heating applications where performance, reliability, and system flexibility are essential. Available in 301 MBH and 399 MBH models, this boiler delivers over 95% thermal efficiency, low NOx emissions, and advanced modulation with up to 10:1 turndown, making it ideal for both new construction and retrofit projects.

Designed for maximum system control, the FT Series features DHW Smart Priority™, allowing simultaneous domestic hot water and space heating without comfort loss. The integrated control platform manages boiler, DHW, and zone pumps, while enabling high and low temperature zoning and cascade configurations of up to four boilers. Flexible venting options (PVC, CPVC, stainless steel, or polypropylene), long vent runs, and a wall-hung or floor-stand configuration allow the FT Series to adapt easily to tight mechanical rooms and complex piping layouts.

Advanced safety and longevity features include an intake air quality sensor that detects flue gas contamination, external intake filtration, and full accessibility to major service components for simplified maintenance. With both top and bottom piping connections, the FT Series offers true versatility for efficient, long-term commercial heating performance.
