  1. I know this comment is probably waaayyy too late to be much use but in case anybody else is wrestling with the same dilemma. The thermoelectric cooler plates (Peltier) can be stacked. I have seen it used to cool imaging devices for astronomy. That way you greatly increase the maximum temperature differential possible an can easily achieve fridge temperatures in all ambient air temperatures. And then for the noise part. The only moving part on the peltier set up is the hot side cooling fan an possibly a cold side air distribution fan. For the hot side you just need to increase the size of the fan to reduce the noise to levels to almost zero. This is done in desktop computer cooling where noise is a concern (media centres, etc.). Actually a CPU heat sink and oversize cooling fan is almost the ideal low noise hot side cooler. And quite cheap. The portable coolers are noisy because they try to save space and use rather nasty and small fans for the hot side which generate massive amounts of noise. The only major issue with using peltier cooling plates is the efficiency. The use a lot of power to achieve their thermal transfer. But with such thick insulation on your fridge the load on the device is likely to be very low.

  2. There was a wintertime, so a bit insulated box outside would have done the job. And even a watertight box what you lower to the sea with a rope…

  4. Great video. So, what did you decide to do? Would love to see the solution. I have a Catalina 27' with a missing icebox. So, I'm looking to create a solution for cruising this Spring!

  5. After all the fridge videos I feel I've become a bit of a theoretical expert!

  8. The out takes are to funny. Made me laugh. As far as the Frig. I have no clue. Ha Merry Christmas

  9. out takes were good. I am going to custom build make box and insert one end into the cold water tank. The compressor cooling fins will be put into the hot water tank to heat the water. So with one unit I get both hot and cold water.

  10. TECs, Peltier Elements, are a Delta-T function. Designs which fail to remove heat from the hot side with a proper heat exchanger is what gives them a bad name. Alter this failure and they function beautifully.

  11. All sailors should be aware that you can make a free off grid fridge that works well with no electricity.   All you need is a couple of plastic bags, some sand, and some water.

    It is called a "Zeer Pot Fridge".  Typically it is built using pots instead of bags, but I wanted to emphasize the simplicity.

    I realize the poster of this video just installed a nice Isotherm unit, and I am not trying to take away from that, but if you want a secondary fridge on deck for your beer then a  Zeer Pot maybe your answer.  They would work great in wind on deck, but not so much in a cabin or galley.   Yet the cost is free once it is built, and building costs could be less than a dollar with ease.

    There is probably a hundred Youtube videos on how to construct a Zeer Pot, but this is how Ice was kept frozen back in ancient Rome/Egypt/Mesopotamia. (kinda).

    PLEASE THUMBS THIS UP SO OTHERS DO NOT NEED TO FUSS WITH ICEBOXES, and find this comment, or spread the word in comments yourself.

    Because.. warm beer sucks.

    Cheers…

  12. I am building a rather large coldbox, in which I plan to use dry ice for short trips of a week or so. When its time for ocean crossings I think holding plates will work just fine. I used to work for one of the companies that made a well engineered system, so I know whats involved to have an economical and efficient system on my boat. For a little box like yours, I think dry ice will work better than spending $500  and up for a twelve volt system. If you are staying aboard using shore power, you might buy a counter top ice maker and use it for filling your little ice box and serving chilled cocktails come sundown,

  13. Hope i'm not too late. I've had both and the Isotherm gave no trouble and the waeco went through a couple of circuit boards(under warranty). The isotherm seemed to get colder quicker and they looked like they had the same pump. I've also made a fridge/freezer by adding a separate box for a fridge next to the ice box. A small sliding door goes between the two to adjust the fridge temperature. It worked very well and was easy to make with ply, foam and fibreglass.
    You'll need a fridge for the beer in summer. Good Luck. Mike

  14. i have a Comfort32 and  i use a combo ,, kompressor freeser box and just freese botles of water to put in my icebox ,   works really well 🙂

  15. NICE videos!

    If it's not to late, check out (Google) Engel coolers! If you head out cruising they use a LOT less power than others!

    Hope you have a great time visiting the US! We splashed in New Orleans last year and had a problem leaving, it was so much fun!! You can see our Youtube video about it. The marina we were at is close to down town.

  16. We have to do the same decision on our Ballad. We consider to buy this one: http://www.svb.de/de/einbau-kuhlschubfacher-coolmatic-cd-30.html I think it will fit exactly below the stove. We will measure it the next days…

  17. Going on power consumption, The Isotherm draws quite a bit less if I've read both he manuals right.  What type of Battery banks do you have or are you only going to run them on shore power?

    Reply
  18. If you get a compressor to upgrade the icebox make sure that the compressor you get has digital temperature control, this in my opinion would be much more efficient.

  19. Try a portable refrigerator/freezer by Engel.  They run on either 12 volts or 110 volts.  They draw very little power when running.  About 2 amps.  Very high quality and fairly expensive.

  20. Mads; There is a bigger decision to be made than this. You’ll be happier with electrical refrigeration especially if it is merely a freezer above with an insulated but unpowered fridge area below (frigid air drops with gravity to chill milk, fresh foods, etc.). This is only one of several electrical appliances. However, you must now decide how to energize your choice (when out at sea). One choice would mimic live aboard-cruising-circumnavigator King Drake Roberts and girlfriend Queen Monique Davis of Drake Paragon fame https://www.youtube.com/user/drakeParagon who favors several solar panels and a windmill generator to recharge battery banks. They love the quietness of this system. After buying a quad drone and extra cameras, they also needed a somewhat pricey pure sine wave inverter to power sensitive high voltage appliances that have no 12 volt inputs. The other choice (my favorite), would be similar to Jules and Suzie of Emerald Steel https://www.youtube.com/user/sujules Supermodel Suzie is also a welder who likes to cook, so Jules bought a plasma cutter, welding equipment, and kitchen appliances for her. He powers it, including his homebuilt water maker and battery chargers with a 4kw diesel generator. There are pro and con aspects of each system. It’s your money. Look at both systems, email these people, ask them questions, so you can decide what’s best for you. As always, your videos are amongst the best on YouTube and your outtakes are most entertaining. Please keep sharing. Thanks. Jack, aka electricalpowerguy

  21. I found that I hardly used the fridge/box on my boat when I lived in London. I kept beer and sodas in the bilge which was more than adequate in keeping drinks cold. My first instinct would be to keep ice in icebox, cheaper and easier. Otherwise, 12 volt fridge with compressor unit installed in engine compartment, running tubes to cold plate in icebox. You will need to review battery amp hours. Tom Peranteau has a great suggestion in a comment below. Good luck on what ever you choose!

  22. Hi Mads! hmm, I see your dilemma.. I just had a thought & call me crazy.. but, could you, if you go with a plate system, tee into the ice-box plate refrigerant lines at the compressor with valving to actuate a remote plate (say, drop-in w/flex-braid lines maybe?) for a q-berth portable cooler? that would up your storage capacity with the ability to disable the remote plate when not needed. Not sure if parallel or series with bypass would be needed to disable plate, or if quick disconnects could be used, etc..all questions for someone in the know, I guess.. but you can see where I'm going with this, lol 🙂

    Me, I went low-buck with a 45 liter removable cooler in it's factory built-in space in my '98 Hunter H26 with a nice (custom sewn) extra insulation jacket (I had a little room around the cooler so I figured why not) it holds a chill for an amazing length of time now.. sometimes 2 weeks or more with block or cubed ice. last summer I bought a small counter-top (100$, very quiet, efficient & actually warms the cabin a bit with it's thermal cycling) cube ice maker to run a couple of hours a week or when needed while at the dock, or through the inverter at anchor for resupply & to have "cocktail cubes" aboard without raiding my home ice-maker. Also, drain water can be filtered and reused if need be.

    Your outtakes are as priceless as ever.. tonight my daughter watched them and belly-laughed right along with me! (now she wants to see the rest of them from your other videos! 😉

    Cheers!!

  23. Hi Mads, 
    Me and my girlfriend own a 27 ft Dufour 2800 and we are considering converting our icebox to a fridge. Like you, we have been debating which brand to have. Unlike you however, we wont be able to do this until the summer as the boat is in another country. We are therefore extremely excited to see how this works out for you. Also, we have been wondering were to put the compressor. Well, anyway, your videos are extremely well made and I enjoy your small projects to no extent 🙂

    Best regards from Iceland, (say Hi to Jökull)

  24. Like your videos, but it would be nicer if you didnt follow a script so closely. In your outtakes, your reactions and tone of voice is more relaxed which actually feels more natural. Best of luck to you 🙂

  25. I've got an Isotherm aggregate and it's fantastic so I vote number 2…

  26. Hallo! And tank you for nice videos!

    I have a Waeco Coolmatic CF-25 coolbox in my Finn 26 sailboat. 23 liters volyme, temperature +10/-18 Cº
    I have it on from mid april to mid october, and with a 50 w solarpanel and 140 amps battery I don't need any shorepower when I use coolbox as fridge. Ca 4-6 Cº
    I live in Finland, Jakobstad ( the town where Nautor Swan and Baltic Yachts build sailboats) so we have more sunlight in summertime then you have in Danmark, so maybe you have to get a slighlty bigger solarpanel?
    Even when it was 30+ Cº last summer it wasn't any problem with temperature inside box. I can't say that soundlevel is disturbing, because I dont hear it normally.
    Ps I havn't used any shorepower for two season since I installed solarpanels and more batterycapacity.
    Regards Lasse

  27. I have the Isotherm build into my boat. However have a bigger coolbox than you. Also bear in mind that the compressor makes noise when it turns on and it needs a kit to fix it into your boat. Which costs another €50 🙁

  29. Mads, I would also recommend looking at FrigoBoat.  They may have components that can provide a small freezer while having a fridge.  On our WS42, we obviously have more space than you do, but we installed 2 Frigoboats.  Our 2.5 cubic foot refrigerator uses a freezer box that provide a small freezer while cooling the box.  Our 1.5 cubic foot freezer uses a cold plate.  The compressors are relatively small and use a keel cooler (a through hull fitted heat exchanger.  The Frigoboat is highly rated here in the Northeast.  However, the units you have mentioned do well, too.  Fair Winds.

  30. I have an interesting icebox on my boat. with access underneath. I have an idea to
    get a cheap small house fridge. like a 1.6 cu ft unit. they are cheap here. less than
    $100. take it apart and mount the compressor under the icebox.

  31. I have a water cooled Isotherm that works well but I would recommend their air cooled version for you.  Unfortunately the harbor where I keep my boat is shallow, especially the boat slips.  That means at an exceptionally low tide the raw water pump picks up mud.  In two years since I installed the unit I've had to replace the pump twice. If I had it to do all over again I would not have purchased the water cooled version. But I was replacing the original unit, which was water cooled too.  Oh, one more recommendation—-don't allow ice picks any where near the cold plate. Although I've never done it, I have numerous friends who have to replace their units do to ice pick punctures.  Good Luck.

  32. Would you be able to continue some more refit work and sacrifice the (or some) quarter berth?  In doing so, you could increase your cockpit locker space on that side, and utilize some space to give you a good sized refrigerator / freezer.  This might mean keeping Obelix a lot longer though.  A supplier here I have found very competitive is Defender Marine Outfitters.  http://www.defender.com/category.jsp?path=-1|2276204&id=2276226

  33. i was wundering if you know about air condistioning units you might be able to find something usefull in the scrapyard to make a heating and cooling unit for the boat to safe space and give you another way to get some heat out of it with the heat transfer so might be something to think about to safe the money in stead of buying one of those expensive kit's i suspect you whould need to do the same amound of work to fit it and all that also i suspect your kit's whould use more electricety then a 12 volt car unit it might be something to at least consider before using $500 on something that might not be better at all 🙂 DIY FTW 😛

  34. Either of those should work, I think they use the same compressor so it is really what fits best and price. If you can get an Engel kit in Denmark, they use a swing compressor and they are much more efficient. I think your box would work well with an Engel, as they are best for small boxes. I am looking at doing a big box and the Engel while my preferred solution would be too small. Though I have thought of going with 2, one side as a freezer and a second divided side as a fridge but that increases the cost and complexity.

  35. haha…rule # 2 is one that I always forget!  I have so many video clips with phone noises!  haha  

    I vote option # 2 for the fridge Mads, because I want to get my existing icebox converted back to a fridge.  It is actually all set up and was a fridge before, but the previous owners removed the compressor from the boat after it broke down.
