Air Conditioners

Marine air conditioning keeps the cabin comfortable in hot climates and, with reverse cycle, heats it in cool weather. This collection includes Dometic self-contained units from 6K to 16K BTU (115VAC), Velair Compact i10 and i16 VSD Smart and 21K BTU VSD units with variable-speed compressors, Mabru 12VDC units that run directly from batteries, and the Termodinamica TD24V1 standalone reverse-cycle unit.

How to choose a marine air conditioner

• BTU capacity: size to the cabin volume, window area and climate.
• Power source: 115VAC units need shore power, a generator or a large inverter; DC units run from the battery bank.
• Variable speed: VSD units reduce start-up surge and power draw, which helps on inverter or small generator.
• Installation: self-contained units need a raw-water pump and ducting.

Can I run a boat air conditioner on an inverter?

Yes, if the inverter and battery bank are sized for the running and start-up load. See marine inverters.

Do these units heat as well as cool?
