Bosch’s Buderus SSB series sealed-combustion, high-efficiency, stainless steel boiler line with condensing technology consists of eight models in four separate chassis sizes with inputs ranging from 85 MBH up to 1,024 MBH. These boilers, which can be cascaded, feature a proprietary ASME SA-240 stainless steel type 316L heat exchanger, an integrated premix burner and a pneumatic air-gas system for optimized combustion. The boilers have a 5:1 turndown, an onboard control that includes weather compensation, mod-bus connectivity, a two-wire cascading link, terminal wiring, and a factory-installed low-water-cutoff and safety temperature high-limiter with a manual reset.
