Condensing Boilers
Dostefos is proud to call Bosch our partner for South Texas. With condensing boilers from 290 MBH up to 5,443 MBH and modular boiler packages up to 8,192 MBH. We even offer dual fuel with fuel oil for those facilities with a back-up fuel requirement.
In commercial sized condensing boilers Bosch offers 2 different models, the SSB and the SB.
The SSB’s are stainless steel, watertube condensing boilers can be ordered to be capable of zero clearance, modular connections for up to four units. The connections are integral to the package and require no other parts. These four units can then be electronically connected to (up to) four more units for a truly modular condensing boiler package.
Each SSB also comes with it’s own multi speed pump, integral to each heat exchanger and controlled by the boiler’s controller.

Bosch SB
A large capacity, condensing firetube boiler, the SB is designed for decades of trouble free operation.

As shown in the photo above this horizontal design provides for complete and easy service access. This makes inspections and fireside cleaning a breeze.
Bosch SSB
The SSB is the only truly modular condensing boiler on the market. Each boiler comes wit two independent boilers in one casing and you can bolt together 4 SSB (TL) boilers for single-point connections.
