Description
For boats with more available installation height, the Flagship FM16H skips the low-profile constraint and delivers 16,000 BTU of cooling and heating on 230V power — the same no-PC-board reliability and quiet LG rotary compressor found across Flagship’s self-contained lineup, in a standard-height footprint.
Key Features of the Flagship FM16H (230V, Cool & Heat)
- No PC board design reduces the electronic failure points common on circuit-board-controlled units
- LG rotary compressor runs quietly enough that some owners mount the unit under a berth
- Soft start capacitors and a stratified startup sequence ease the load at compressor startup
- Dry drain pan design keeps the rotary compressor from sitting in its own condensate
- Recommended for installation on a 25-amp breaker per Flagship’s guidance for units in this BTU class

Why Choose the Flagship FM16H
Without the 11-inch height restriction of the RLP series, this standard-profile 16,000 BTU unit is generally easier to service and access for maintenance — a reasonable trade-off if your boat doesn’t have the tight clearance that makes the low-profile models necessary. The dry drain pan design is a specific detail worth noting: rotary and scroll compressors under 48,000 BTU in Flagship’s lineup don’t sit in standing condensate, which reduces long-term rust risk compared to designs that do.
This 230V configuration draws considerably less current than the 115V version of the same unit for equivalent output, which matters if your boat’s 230V circuit capacity is more available than 115V.

Flagship FM16H 230V AC FAQ
What voltage rating does this system use?
Flagship FM16H utilizes a standard 230V electrical feed. This international single-phase layout fits global shore networks and heavy-duty yacht generator circuits, permitting vessels to run full reverse-cycle climate control without loading lower-voltage ship service lines unevenly or tripping main breakers at foreign marinas.
What are the physical dimensions of FM16H?
Flagship FM16H features a footprint of 16.5x16.5x14 inches. These square chassis proportions grant installation engineers clean placement flexibility, allowing a direct drop-in mount beneath lower salon booths or inside engine room compartments where vertical room can comfortably accept standard-height machinery setups.
When is Flagship FM16H best applied?
Flagship FM16H is best applied as a primary climate controller for offshore sportfishers. The system handles main salons or large master staterooms on vessels from thirty-four to forty-two feet, utilizing its heavy-duty reverse-cycle heat pump assembly to maintain custom interior warmth during cold-weather winter fishing trips.
