A boiler that performed adequately through last heating season may not perform adequately through this one. The difference is not always the boiler’s age or its mechanical condition. Sometimes it is the load. As outdoor temperatures drop further and hold there longer than they did in previous seasons, the boiler plant operates closer to its
Viessmann is a German heating technology manufacturer with a commercial boiler product line that covers condensing hot water boilers, high-efficiency fire tube boilers, and large-capacity watertube boilers for commercial and institutional applications. In North America, Viessmann commercial boilers are specified in schools, hospitals, universities, multifamily residential buildings, and institutional facilities where efficiency, reliability, and long
Every commercial boiler reaches a point where the repair versus replace calculation tips toward replacement. That point is not always obvious when it arrives. A boiler that has been repaired regularly and is still producing heat can look like a functioning asset right up until the repair that costs more than the remaining useful value
A boiler failure during heating season is not a maintenance problem. It is an operations problem. The building is cold, the occupants are calling, and the decisions made in the first hour determine how quickly heat comes back online and how much the recovery costs. Most facility managers have never managed a boiler failure before
A commercial or industrial boiler is only as reliable, efficient, and safe as the control system managing it. The burner, the heat exchanger, and the pressure vessel are the hardware. The control system is what determines whether that hardware operates correctly, responds appropriately to changing conditions, protects itself and the building when something goes wrong,
Most commercial boiler reps focus on the boiler. The equipment that makes the boiler work correctly, the deaerator that removes oxygen from the feedwater, the boiler feed system that delivers that water to the boiler at the right pressure and temperature, the condensate return unit that recovers and recycles steam condensate, receives less attention in
The pre-season boiler inspection covers the mechanical side of the system. Combustion analysis, safety control testing, heat transfer surface inspection, breeching review, and controls verification. All of it matters. None of it accounts for what is happening in the water. A boiler that is mechanically sound and chemically neglected will develop scale, corrosion, and oxygen
Hurst Boiler and Welding Company has been manufacturing commercial and industrial boilers since 1967. The product line has expanded considerably since then, covering fire tube, watertube, biomass, solid fuel, and hybrid configurations across a capacity range that spans from small commercial applications through the largest industrial steam plants. For engineers and facility managers evaluating a
A commercial heating boiler that has been offline for the summer starts up in a straightforward sequence. Verify the controls, confirm the water level, fire the burner, bring the system to temperature. The building is warm. The process is largely the same every year. An industrial steam system startup is a different exercise. Process steam
The commercial boiler specification process involves more decisions than most facility managers and engineers expect when they start one. The boiler itself is one decision. The breeching and stack system is another. The efficiency rating on the specification sheet needs to be interpreted correctly to mean anything useful. The control system needs to match the
