Commercial boiler advances enhance facility design, management
As efficiencies rise, the size of commercial boilers continues to shrink.
The advances in technology and design have revamped the way in which buildings are planned and designed. No longer does considerable space have to be dedicated to a boiler.
Nowadays, they can be situated on a small footprint or anchored onto a wall, allowing facility owners and managers to more effectively use their valuable real estate.
It’s not just new construction that has been impacted positively. The new design of boilers makes them as viable a solution for retrofits as any other project.
Bosch Thermotechnology’s Buderus SSB industrial stainless steel boiler, which it showcased at AHR Expo 2018 in Chicago, is helping commercial customers who are focused on efficient space heating and domestic hot water.
“It’s really different than what you’re seeing out there in the industry,” said Justin Stevens of Bosch. “What’s really different is the modularity – the fact that each is designed as a single unit. You can use it as a standalone or bolt them together into one big boiler.
“This allows people to bring in a new condensing boiler into some of those rooms they couldn’t get a condensing boiler into. If you need 4 million BTUs to replace an old cast-iron boiler in a utility room you couldn’t get to before, now you can do that.”
The Buderus boiler, at 96 percent thermal efficiency, offers an integrated cascading design that allows users to easily quadruple output if desired by simply connecting them with a gasket and additional hardware. The boilers, designed in scale to fit through a doorway, are available in 798 MBH and 1,024 MBH standalone units, or a 1024 cascading unit, to meet demands up to 4,096 MBH. That makes the system, the company said, an ideal solution for applications in schools, hotels, office buildings and warehouses.
The two largest commercial size units feature side-by-side twin heat exchangers for efficiency and redundancy.
“It’s like two boilers inside one cabinet,” Stevens said.
The Buderus boiler also includes a 7-inch touchscreen display on the exterior to easily set system operating parameters and provide managers information on functionality while also connecting into a building management system.
The boiler features zero-clearance functionality, enabling the units to set within two inches of a wall without the operation or ventilation to be hampered.
“That frees up room in these boiler rooms,” Stevens said. “Boilers nowadays are a lot smaller than they used to be. This allows room for other things in your utility room.”
