I removed a 36,000 btu heat pump chiller with 7 electronic controlled fan-coil units.
About the best system you could get, and the most expensive.
But, for many reasons during this refit
I removed it all (its for sale).
I installed a very high-end heating
system (heating only).
For air-conditioning I purchased one 6,000 btu system ($150) for the cabin
. The smallest one on the market is 5,000 ($100) and more than adequate, but the 6,000 has a remote
. Important as will not be very accessible.
I also bought a portable system for the saloon
. About 14,000btu?? ($450)
It is VERY important for efficiency that they have 2 hoses for the condenser. Many have only one - and will be next to useless, as they use (cooled)room air to cool the condenser and exhaust
it.(not very efficient). I have it mounted. but installation
is not complete.
The larger portable is for dock
use only. The smaller bunk could be used from inverter
- if necessary - but usually not.
My motivation is cost. I can't imagine what on a domestic unit is not "marine". And there are no extra holes in the boat. at $150 it is disposable...
I removed over 10 thru-hulls during this refit
- including the condenser water
