Condensing boilers offer installation flexibility
A new range of stainless steel boilers in eight sizes offers customization and installation flexibility from small multifamily up to larger commercial buildings.
At the 2016 AHR Expo, Tom Kelly, manager applications, training and technical services for Bosch Thermotechnology, reviewed the new offering in the Buderus SSB Series of high efficiency stainless steel boilers.
The Buderus SSB Series consists of a total of eight models in four separate cabinet sizes with inputs ranging from 85MBH up to 1024MBH, and are applicable for use in small studio units all the way up to commercial buildings.
Bosch introduced the new SSB Series mid-size range 255, 399 and 512 MBH models initially, and in mid-2016 will introduce 85, 120, 160 MBH res- idential models, followed by 819 and 1024 MBH commercial sizes. The Buderus SSB Series is designed as a modular platform for commonality and familiarity for the installer, for quick and easy installation in various applications. The platform commonality also reduces the number of unique spare parts in inventory.
The SSB225 (residential) model is rated at AFUE 96%, while SSB339 and SSB512 (commercial range) are both rated at 96.8% Thermal Efficiency. All sizes have a turn down ratio of 5:1, delivering precise load matching and ultimate efficiency.
These boilers, which can be cascaded, feature a proprietary ASME SA-240 stain-less steel type 316L heat exchanger and an integrated premix burner and a pneumatic air-gas system for optimized combustion.
They can be vented using CPVC, PVC, PP, PP Flex, Stainless Steel AL29-4C, IPEX type IIA & IIB for use with single- pipe, two pipe or concentric configuration.
Buderus SSB boilers have a 5:1 turndown, an onboard control that includes weather compensation, mod-bus connectivity, a two-wire cascades link, plus terminal wiring.
They also feature a factory installed low-water-cutoff (LWCO) and safety tempera- ture high limiter with a manual reset to speed installation.
Also pre-installed in the larger units (sizes 512 to 1024 MBH) are CSD-1 compliant low and high gas pressure switches. The larger commercial size units feature size- by-side twin heat exchangers for efficiency and redundancy.
Buderus SSB units installed in residential applications have a 10-year limited war- ranty on the stainless steel heat exchanger and a 5-year limited warranty on parts and labor at Bosch approved rates. For boilers installed in a building other than 1-2 family residential dwellings, the other boiler parts have a 2-year limited warranty, excluding labor charges.
