The Combi1™ 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. Because of its single wall heat exchangher design, the Combi1™ provides approximately 40% more space heating output when compared to a double wall heat exchanger design.
