Hydronic Disconnect

SENWiEcoSENWiEco Member Posts: 98
Hi Folks,

Coming to the end of my hydronic design and getting into the more experimental part of the system. I would like to look at some form of capillary mat for the master bed. Mainly, I would look to cool down pillows in the summertime (but possibly mattress warming in winter as well). For this, I am hoping for some form of quick disconnect I could place in the floor or the wall by the bed. Does anyone know of a product like this. It would function something like this outdoor hose bib disconnect, the water does not flow until the nozzle is clicked into place (https://aquorwatersystems.com/shop/universal-outlet/).

Obviously I want to prevent spills of the treated water but also prevent entry of air which is why the above would not be suitable. would need to be more like hydraulic line disconnects that seal off both side of the disconnect.

Thoughts?

    Go for it. I think I might just use hydraulic line disconnects. They're easy to get and should work just fine.

    I'd say hydraulic or air hose quick connectors would be fast and almost drip free.
    Maybe check out these therapy pads. Mainly you put ice water in them, I suspect they would work with warm. Be nice to find just those pads. This is the Iceman brand.

    I think a couple of things need to be addressed:
    1. Can the mat withstand the pressure of the system to which it would be connected?
    2. If your planning on connecting this to a hydronic system (I hope not), how would you deal with air removal?

    Thanks @Jamie Hall @hot_rod for your follow up.

    My research is currently steering me towards something like https://www.staubli.com/en-us/connectors/market-solutions/motorsports/hydraulic-applications/compact-clean-break-motorsports-cbr/

    I want something that seals off both sides of the connection which is why I cannot use air line connectors. With both sides sealed, I would only have to bleed the capillary mat once (Which I could do before I install connectors, and then we would be good to go.

    This is sort of what I am thinking for mats

    Next issue would be how to protect from damage/puncture during use. Mights work to put in a mold and pour in some latex rubber compound to imbed mat in protective layer.

    Thanks @Ironman - yes I am looking at connecting to the hydronic system, that is the whole point. See above for my thoughts on air control. This would deal with bulk of air, but yes I would have O2 that would probably permeate into the mat over time depending on material. Yes of course, the assembly would need to take the 20-25 PSI that the system will probably run at.

    maybe use an hx and put the mat on an open tank with a small submersible pump in it?

    @hot_rod, I was thinking the same thing. With quick disconnect hoses. I've used that after knee surgery only mine was like a mini Igloo cooler. A clear vessel would have been a nice addition to the percocet trip.

    McMaster Carr has Quick disconnects used in the Brewery and Wine industry. Both ends seal BUT a small drip is possible.

    Be advised there not cheap by any means!

    @HVACNUT @hot_rod I have the complete https://www.orthocanada.com/en/aircast-cryo-cuff-complete-kit system, but I do not think this would handle the pressure.

    thanks @pecmsg - another industry I can look into. Hopefully they have something as small as 3/8"-1/2". Not worried about a few drops, that can be managed. The pad would not be disconnected often. If not wanted for extended time, I could just slide into a drawer built under bed.

    The 3/8 Watts Onix is flexible and rated for hydronic temperature and pressure. Bends down to 4” OC.
    Dahl mini ball valve could be added to disconnect union, like a compression coupling

    i will recommend Stainless Steel. More money but worth it.

    @hot_rod how reliable are those Dahls valves? I have used a few and haven't had a problem so far, but I don't trust valves that operate that easily.
  • hot_rodhot_rod Member Posts: 13,737
    All ball valves work great when they are new. it seems the more you use them the better they work or last.
    leave one for 10 years and they tend to not want to work so well.
    The Dahl is a quality bar stock machined valve, but no stem packing that you can tighten.t
