- Cool-and-heat operation enables dual-mode conditioning.
- 1.7 kW rating identifies listed output.
- Marine unit manages cabin temperature.
A compact 230V cabin system can provide both cooling and heating without requiring a larger salon unit. The Flagship FM9H delivers 9,000 BTU/h of cooling and 5,800 BTU/h of heating through integrated 1.7 kW electric heat strips. Its application guidance identifies the system for under-bunk cuddy layouts up to 350 cubic feet and lists a minimum generator capacity of 2.8 kW.
Who This Unit Is Not Ideal For
This model is not suitable for boats limited to 115V power or buyers specifically seeking reverse-cycle heating. Its 9,000 BTU/h cooling capacity may also be insufficient for larger salons or spaces beyond the stated 350-cubic-foot guidance. The electric heating function requires suitable generator and shore-power capacity.
Warranty and Product Summary
The Flagship FM9H includes a five-year limited factory warranty. It combines 230V cooling, electric heating, 300 CFM airflow, compact dimensions, and self-contained marine construction for compatible cuddy and small-cabin installations.
