Mermaid M16 – Cool and Reverse Cycle Unit 16,500 BTU’s 110V

Standard 110V power remains the norm on most US boats, and the Mermaid M16 Cool and Reverse Cycle in 110V trim delivers 16,500 BTU of cooling and heating without asking for a voltage step-up — sized for cruisers up to 40 feet or sailboats up to 45 feet. One verified owner review specifically praised the ice-cold cooling and efficient heat side performance after replacing an aging 2008 R22 unit.

Why Choose the Mermaid M16 (110V)

Real-world feedback on this unit is notably positive: one documented review described replacing a failed 2008 R22 unit and finding the newer R32 refrigerant charge “hyper efficient,” cycling faster than both the old unit and comparable Dometic models a neighbor had installed. The same review also noted responsive customer support when a fan component failed under warranty.

A second review flagged the included thermostat’s programming as more complex than needed for owners who just want simple on/off cool or heat control — worth knowing going in if you prefer straightforward controls over extensive scheduling options.

What to Know Before Installing

• Pump is not included and must be sourced separately
• Plan for three discharge points: one 8″x6″ grill within 6 feet of the unit, plus two 4″ round vents
• The included thermostat has extensive programming options — budget time to learn the interface, or expect a short learning curve per owner feedback
• Confirm your boat’s electrical panel supports the 13.5A draw at 110V
