You can view some photos of water maker installations on various boats here, which will give you a mental concept
of the size and mounting space required for a 120v AC high output water maker.
Watermaker Reviews & Testimonials | Cruise RO Water & Power
The Big starting point question for you to make is how will you power the water maker. There are two schools of though there and the "right answer" will depend on YOU and how YOU want to set-up your boat.
I'll summarize the two schools of thought for you, but remember there is no "right answer", but just perhaps a "best answer" once you understand the strengths/weaknesses of the different approaches and mesh that with what you need on your boat.
[[Now I sell 120v AC high out put units in full disclosure but I also see the value in the 12v DC lower output units...it all depends on what you want/like]
12v DC Water Makers
The ability to make water strictly from your 12v DC battery bank and have the power replenished from your Solar
, Engine alternator
when motoring, or generator.
Do not need a generator to power.
Higher cost with a more technically innovative energy recovery pump
Lower fresh water output per hour
Spectra would honestly be my only real choice here, their service
is top notch, and when it comes to going 12v DC what really matters is how many Amp Hours it takes you to make a gallon of fresh water. Flat out, no one beats Spectra at about 1 Gallon per Amp hour.
120v AC Systems
You can make a lot of water quickly (20 or 30GPH) for less initial purchase
cost while running your ships generator or a Honda
Make water 2-3 times per week due to the large output.
Have a system with more off the shelf components that helps keep servicing costs down.
You need to have either a Generator (Diesel or Honda
2000) but you can use a 2000w inverter
while motoring with your alternator
running. But you are looking at a primary generator powered system.
RO (Me), FCI Water Makers, Water Makers Inc, There are lots of 120v AC water maker companies because most of these types are using more off the shelf technology without energy recovery pumps. So the difference from Company to Company has a lot to do with the extend they load the water maker up with electronic.
If your boat already has a diesel
generator that you plan to use several times per week, then the argument for a 120v AC water maker is easy. Just flip on the water maker during your already planned generator run time. If your boat doesn't have a generator and you don't want one, then likewise your decision gets easy, you buy a Spectra hands down in my opinion.

You can get a good feeling for most AC 120v water makers by giving it a review. Now we don't play the electronic controls game
, so some water makers that have those will add $2-8K (yes that is right..a HUGE adder) for the same output as a manual system to trick it out with all the latest touch screen
controls and IPhone
connectivity. Me...as a live aboard cruiser myself well I think that stuff is crazy, but there is a market for it, and if you go to the Big Boat Shows around the Country you see them everywhere.
Good luck with the decision and Tellie is a valuable resource and I try to be as well.
