We are looking to replace AC unit for salon. Challenge is where to place the hot air exhaust. Previous user had a freestanding unit with hose out the hole in salon window-would like to find a better functional alternative.
Marine AC units are water cooled. The "hot air" is removed by cirulating water and out the side of the boat. That is if I understand your question correctly.
Thank you for your comment. I am a novice on this and am relying on other folks that may have experience in our area. Do you have a particular Marine AC unit in mind? I have not been able to find something small enough without the "air vent" that she had pushed out of the window. We are on a Lake and not the ocean and from I can tell many of the houseboats on the lake are not using marine units. We are meeting with an electician tomorow to have him give us an idea of what kind of unit the boat will support.
Several of the 35 owners installed stand alone ac/electric heaters years ago. If you search "marine air conditioners you will find an afternoons education and list of questions for the electrician.
Big difference. I would assume you have two 30 amp circuts. I would also think that the boat would have had AC at some point and if so it would likely have been a split system which should have been noted on the survey. That said, I would suggest you find a qualfied marine mechanic or an HVAC/Plumber that works on boat AC. I would recommend looking into a self contained system from someone like Webasto or other manufacturers.
Jackie, I have a 42 also. Below is a post I made to a fellow club member with a 41. Very similar layout to our 42's Biggest difference is the 42 has a greater sun load due to the salon windows. Hope this gives you some background. Feel free to ask any questions.
Hi Hap,
As you know I have the 42 down the dock from your friend Keith. I went with self contained units. I have 18,000 for the salon. 7,000 for the aft stateroom and 9,000 for the front v berth. The v berth unit splits 1/2 of its output into the salon. The 42 has an extreme sun load and while the 18k unit is a great unit, on 80+ days, it needs some help. We like our boat cool, so this is what I ended up with. The BIG drawback on the self contained units is noise. They can not be in the bilge, or anywhere that bilge fumes can leak into the intake. This puts them well within ears reach of noise. Some sound deadening can be done, but they will never be as quiet as a split system with the compressors in the bilge.
If I had it to over again, I would still go self contained, but I would put a little more thought into unit placement keeping in mind noise levels. One piece of advice I will give is to go with a simple system. Get ones that use basic electrical components and NOT circuit boards. On the newer fancy ones if a board fails (and they do!) you are buying a new unit for what the boards cost.
The systems I have use standard thermostats and electrical components readily available anywhere.

You might need to add another shore power inlet, the 35s came with a generator double the amperage of the shore power inlet.
