Description
Buderus SM80 is a vertical, dual-coil indirect hot water tank with 75.4-gallon DHW capacity. It features Thermoglaze ceramic coating (on both tank and coil), (2) magnesium anode rods for superior corrosion protection and large front clean-out for easy access and maintenance. Dual-coil design allows to use two heat sources (i.e. boiler and solar).
