Commercial Boilers

A commercial boiler is an ASME-code pressure vessel that burns fuel — usually natural gas, propane, or fuel oil — to produce steam or hot water for a building or process. These boilers are designed for commercial heating and industrial applications, providing reliable heat through advanced technology and controls. Commercial boilers come in a variety of designs including firetube, watertube, and modular on-demand, available in both wall hung and floor standing models to meet flexibility and space requirements.

There is no honest one-number answer — installed cost is driven by capacity, pressure, architecture, fuel train, emissions requirements, controls, and the condition of the room it's going into. Two 300 BHP projects can land far apart for good reasons. What we can do is give you a real budget number for your actual conditions, fast — free, and without a hard sell attached.

Size to measured demand and load profile, not to the nameplate of the boiler you're replacing — plants change, and the old unit was often oversized on day one. As a starting point, 1 boiler horsepower ≈ 34.5 lbs of steam per hour from and at 212°F. Our products and technology ensure reliability and easy maintenance to meet your operational needs. Send us your load data and we'll run the sizing with you before anything gets specified.

Choosing between firetube and watertube boilers depends entirely on your specific load requirements and operational needs. Firetube boilers are celebrated for their reliability, simplicity, and stable performance, making them ideal for steady, mid-range load applications. They typically offer moderate to high efficiency and are well-suited for many heating applications and replacement projects. On the other hand, watertube boilers excel in delivering higher pressures, larger capacities, and superheated steam, with efficiencies often exceeding 85%. Their design is preferred for high-pressure steam, large campuses, and heat recovery systems. Watertube boilers require more disciplined water treatment but provide superior performance in demanding industrial environments. Each boiler type features stainless steel heat exchangers and advanced controls to optimize efficiency and emissions compliance. Selecting the right commercial boiler involves assessing your load profile, space constraints, fuel options, and maintenance preferences to ensure long-term operational efficiency and cost savings.

Victory Energy (FRONTIER firetube; VOYAGER and DISCOVERY watertube) and Miura (LX and EX modular on-demand) — supported by Industrial Combustion and Limpsfield burners, Autoflame advanced controls, Industrial Steam deaerators, Heatmizer heat recovery, Van-Packer stacks, and AirPro fans.

Yes — parts is a standing lane at Tri-Tech, not an afterthought. We keep over 20,000 parts in house — controls, gaskets, trim, and wear parts across the lines we represent — so the fix doesn't wait on a factory lead time. Our products make it easy to maintain your system's reliability and performance.

Yes, we supply wall hung commercial condensing boilers that deliver high efficiency and space-saving design ideal for commercial heating applications. These boilers use advanced condensing technology to achieve very high efficiency, often exceeding 90%, by capturing and reusing heat from exhaust gases. Wall hung models are perfect for facilities with limited boiler room space, offering easy installation and maintenance access. Our wall hung commercial condensing boilers incorporate the latest innovations in boiler technology, including stainless steel heat exchangers and advanced burner controls to optimize combustion efficiency and reduce emissions. These boilers also comply with strict environmental regulations, ensuring your facility meets current and future emissions standards while lowering operating costs.
