The IBC DTI 119-Max is an InterStor indirect-fired water heater with a stainless steel tank and a stainless steel heating coil. It is heated by a boiler: hot boiler water runs through the internal coil and heats the domestic water stored in the tank. IBC designs the DTI series to pair with its condensing boilers, and it can be integrated with an existing boiler system.
