1. You may need a grundfos submersible pump with a 7meter head pressure. I use this on my septic system to push the liquid around our property. It’s been in the 14 years and counting. Pushing the grey water around through 1” pipes.

2. You may need larger diameter line on discharge side to overcome the friction loss in the line.

3. Head is not just height difference. You have to include k factors for fittings and tubing. Smaller tubing will increase pressure but decrease flow always.

4. Thai is one amazing dude..he's missed his calling..he has a wealth of boat savie and a greater teacher and presenter

5. Ty, I am learning so much from you. Thank you.

6. Ty, not sure what the spec was on those pumps, but it sounds like you need a higher operating pressure pump. Maybe try out this from Northern Tool. WWB-06618. It's designed for sprayer applications.. which have high restriction nozzles.

7. Do you prefer Home Depot over Lowe's? I've always wondered if there's any major quality/experience difference between them!

8. i certainly wouldn't use a single pump to power all my A/Cs, a boat is all about eliminating single point of failure. The beauty of having multiple of the exact same item (pumps, bilge circulation, AC units, etc) is the redundancy offered and carrying a single backup. In an emergency you could even swap the whole AC units if on a long voyage, if for example your master suite AC went out and the guest AC was the same.

9. Did you try putting those pumps in series? Might help overcome the restriction challenge.

10. Great video. We don't get near enough insight into the engineering, problem-solving, and frustration that goes into designing a really great efficient boat that does everything, so thanks for the insight. Efficient AC is the holy grail of boating in the tropics, and so it's very interesting to see you come up with a solution when the big companies fail at it so consistently.
    What do you think the % diff between your solution versus a Prestige (for example) Chiller solution will be?

11. i would recommend an external tint by 3m that rejects IR and UV this will help lower your heat ingress.

12. Why one pump for all your ÁC on the boat. If the pump fails ALL the ÁC goes with it.

    A water system using ‘headers’ is very hard on pump ‘head’ performance, individual smaller pumps, one for each ÁC unit would be far better. Looks like you have enough pumps for two boats now. To check/commission one ÁC unit, run the water system on a simple temporary one pump and line system, ie KISS

13. every bend adds resistance + height ײ

14. Just a heads up Be careful using those pvc ball valves. I have a salt water aquarium and after 12 months they are pretty much seized and can’t turn them on and off. The salt water must do something to the internal ball

15. This wasn’t even a video it was a waste of time.

16. I don't like the idea of sea water pumped through the ac heat exchanger, a glycol loop with a water to water heat exchanger in a sea chest would be much easier to maintain

17. I ran the fresh water hose through mine DC units to charge to the correct weight of Gas Ty. It got very hot during the gassing phase. One it had the required volume of gas I then ran the normal 24v in my case pump. My luck is the aircon is under our bed so the head is about 0,5m

18. I don't know your specs, but I have ran two pumps in series to get the performance I've needed. Also, as a rule, smaller hose will not improve flow. In hydraulic systems, pressure is created by the resistance to flow. Great information on AC units. Looking forward to seeing your results. s/v Salty Britches

19. Every 90 also reduces your pressure and volume.

20. I didn't see you bleed the air out of yellow line by bleeding r134 thru ,thus inducing air into the system

21. Sorry about the protracted a/c solution! Most comments are over my head, but seems like some good suggestions in there,,,,, good luck! We are gettin a cold front here in Fla on Friday- it might get down to 84 😱

22. 👍✅🏝 Great content, tks for sharing!

23. with that amount of ac units maybe you should get a tank of 134

24. You should also consider when you in another country?

25. 6:56 had todo a reenactment? That cans already pierced lol.

26. As much as I like overengineering things myself – building a solution for a problem occuring every 5 years (Barnacle buster) which itself needs service every 2 years (that plastic stuff and salt water really don‘t like each other) seems a bit out of context… 😜🤣

27. Quick question is the water necessary to cool the unit because you aren't exhausting hot air out like a conventional AC unit ? Also, what is the temp of the water on the output side? Would it be possible to recirculate water from a separate fresh water holding tank that you could occasionally fill from your watermaker?

28. Since I started watching you and I watch parlay revival in spirit animal, the technical stuff you guys need to know is amazing your air conditioning units and then setting it up hurts my brain. God bless you. I love that you can do it because it amazes me that you can do all the stuff that you need to to run a boat well done

29. Gringos pumps is what I used on my ground source heat pump . Don't know if that will help

30. Have been following you for 2 years now. Always enjoyed them, but the videos you do now are pure gold. Thank you for your excellent work and sharing it!
