Details
Single or dual heat exchangers The Stiebel Eltron SB/SBB series water heaters are indirectly fired and are equipped with either one or two large heat exchangers. The heat exchangers are heavy gauge steel with procelain enamel coating.
Flexible options The models with a single heat exchanger can be used for solar applications with some form of external backup heater. On the models with dual heat exchangers, the upper coil is typically connected to a space heating boiler fired by any fuel and the lower coil is connected to the solar panels.
Multiple uses. All Stiebel Eltron SB/SBB series water heaters can also be used as high capacity indirectly fired water heaters in conjunction with any type of heating boiler.
