Mermaid M16 16500 BTU 220V Reverse Cycle Heat Pump
The Mermaid M16 heat pump provides 16,500 BTU reverse-cycle capacity with 220V power for marine cooling and heating applications.
- 16,500 BTU output handles medium cabins.
- 220V input guides electrical compatibility.
- Reverse cycle supports heating operation.
- Heat pump delivers dual-mode conditioning.
- Marine installation requires matching power.
Not every boat runs 230V, and the 220V version of the Mermaid M16 Cool and Reverse Cycle brings the same 16,500 BTU cooling and heating platform to vessels wired to that slightly different voltage standard — same construction, same capacity, same installation requirements as its 230V counterpart.
Why Choose the Mermaid M16 (220V)
Electrically, this performs identically to the 230V version at the same 13.5A running amperage — the voltage input is the real distinction, relevant mainly for boats built to or imported from markets using the 220V standard rather than the more common US 230V.
Confirm your vessel is genuinely wired for 220V rather than 230V before ordering, since the two aren’t always interchangeable depending on regional electrical conventions and what’s already installed onboard.
What to Know Before Installing
- Plan for three discharge points: one 8″x6″ grill within 6 feet of the unit, plus two 4″ round vents
- Pump is not included and must be sourced separately
- Verify your vessel’s actual voltage standard (220V vs 230V) before ordering
- All three air discharge positions are available on this model
