Flagship FM16H 16000 BTU 115V Marine Air Conditioner
Flagship FM16H specifies 16,000 BTU marine air conditioning with 115V power for vessel climate control installations onboard systems.
- 16,000 BTU rating supports medium spaces.
- 115V input matches listed systems.
- FM16H identifies listed model configuration.
- Marine conditioner serves onboard interiors.
- Capacity guides equipment selection for cabins.
Standard 115V shore power gets the full Flagship treatment with the FM16H — 16,000 BTU of cooling and heating from a no-PC-board design that Flagship has built around rotary and scroll compressors quiet enough that some owners mount the unit under a berth.
Why Choose the Flagship FM16H (115V)
This is the standard-voltage option for most US boats, avoiding the need to step up to 230V just for this unit. Current draw runs notably higher than the 230V equivalent — 11.3A versus 5.7A cooling — which is expected given the voltage difference, but confirm your panel and breaker can comfortably handle the 18.1A heating draw before committing to installation.
The dry drain pan design is worth noting specifically: Flagship’s rotary and scroll compressors under 48,000 BTU don’t sit in standing condensate, which reduces long-term rust risk compared to designs where the compressor stays wet.
What to Know Before Installing
- Confirm your electrical panel supports the 18.1A heating draw, the highest current requirement on this unit
- Units are made-to-order with roughly a 2-week lead time before shipping
- Choose top or side discharge based on your installation layout before ordering
- A dedicated FM16 install kit is available separately for a complete setup
