The Combi2 Series combination water heaters are designed to provide both potable water heating and space heating from a single heat source. The heated potable water in the tank transfers its heat through the heat exchanger to the fluid within the coil. The double wall heat exchange coil also provides added protection, required by certain municipalities, against the mixing of potable water and space heating fluid.
