Stiebel Eltron 221222 Model SBB 400 S Domestic Single Heat Exchanger Hot Water Tank for Solar, Geothermal or Hydronic Applications; 108.6 Gallon Storage Capacity, 150 psi/10 bar Working Pressure

All Stiebel Eltron SBB/SB-E series tanks are made in our factories in Germany and Slovakia. They can be used in residential or commercial installations as indirectly-fired domestic hot water storage tanks in conjunction with any type of boiler, geothermal, or solar hot water application. The vessels and heat exchangers in SBB/SB-E tanks are made from heavy gauge steel. All surfaces in contact with domestic hot water receive a thick ­porcelain enamel coating after shot-peening to clean the steel surface. Up to three inches of urethane foam insulation ensures that hot water stays hot, and standby heat loss is minimized.
