I cool my house with water based AC too.... I use chilltrex units and a custom water chiller I designed with 4 tons stored overnight so only my pumps have to run after the sun is down. Of course my house is designed super efficient with ICF Mikey Block, no air gap flat insulated roof and insulated slab/footers. My whole unit is 2 tons and uses 1650 watts. Chilltrex cooler was 220v and 12 amps max. Thats about 100 amps on my 24v battery system. So I designed my own with (2) 1 ton super efficient chillers. Working great and uses less than a third of typical home cooling for a 2850sq ft home.
super excited about this series! I'm also a big fan of water and have, as far as I know, the worlds only geothermal water greenhouse. I just added a chiller to it and you've turned me on to the capabilities of hydronics for many more applications.
LOVE making COLD AIR with the power of the sun!!. God Bless Brother.
My uncle was working on a similar project. He was going the ultra cheap route. He had an old irrigation well that was very deep. He collected automotive radiators for coils. He was going to run it as a secondary system. He had a big farm house that was costing a lot to cool. Not sure if he ever finished it.
All we need is the practical engineering & the labor , let’s go men. ( and women , of course )
Very simple air conditioner for a small yacht. Using a small 12vdc submersible pump that will raise water at least 20 ft pump the cold water through a used heater core from a wrecked car and back into the lake.This core should be enclosed in a metal box of sorts with fins exposed. Connect a 12vdc computer fan in the box to blow through the heater core.
Water from the lake at that depth will be cold and while running will cool your yacht considerably. Mine works just fine now for 20 years. Water at my dock 20 ft down is 56ºF in summer. My well water at home is 52ºF all year. Hope this will work for you.
My dad had a buddy with a house built over an old well. He got a radiator out of an old junked pickup, plumbed it into the well, and set up a fan to blow air over it. The well water was plenty cold enough to handle a Nebraska summer. Not sure I'd try to do it much further south than that, but with the solar-powered ice production to build up that "bank of cold", it should be workable pretty much anywhere (because the hotter it is, generally the more hours of sunlight you have anyway).
I have been thinking of building an air cooling hydronic unit for a long time. I have a natural spring that feeds my pond in the back yard. Here in Indiana ground water temps are around 53F. I already heat with outdoor wood boiler. pex tubing on the bottom of the floors.......I basically can heat the house on around 300w of power with the boiler blower going, and the circulating pump going. The furnace is only a backup system.....and they are not connected to one another.
Got a vid
What! U went to school were John Siegenthaler went! That’s awesome, my plumbing teachers in apprentice school made us read his books. But Dan Holohan is still my fav. ...probably cause he’s not a engineer..hehe..thanks for all ur great content ✌️
You should convert to R290 propane refrigerant, look how is saves compressor load! Saves recovery hassles too. Two cans 20 each should be plenty. I was amazed how less = more. You'd be safe, it's only outdoors, in worst case leak.
Agree. Either R290 or CO2 in a mono-block is perfect for water heating in the north.
i like it... i am always thinking along the same lines. love your vids!
Looking to implement a system similar to what you had planned in a new house build. Any progress since you posted this? Can you recommend any other resources putting together something like this?
This summer im going to (attempt) cooling my house using the 55-60 degree water that constantly flows in the creek next to my house.
My plan is to make a ram-pump to freely pump creek water to a storage tank that will sit at the highest elevation on my property.
From there I'll let the water gravity flow to intake port on the A-coil in my furnace/duct work.
Then I'll just turn the furnace to "fan" and that should in theory keep the house cool.
The discharge flow will just go back to the creek from which it came.
At some point, I'd like to figure out a way to make the water flow power the blower fan so the whole system will be totally self sustained.
LeeRoy Dundlehay I’m thinking about doing this for my shed.
hydronics is great way to do things. have to be careful on the piping so you don't have gost flows. pipe size is also very important. I've done lots of it over the years. curcilators take power. once a gin pipe sizing for smaller circulators is a must.you can do it just a lot of planning
So, is this system more efficient than other approaches?? What are the main advantages over other technologies/ methods?
Are there any poly lined pipes that can be used? My water is hard and eats all plumbing. Thanks and I am confused and wondering
I understand the cooling, but are you heating your water with solar? What does your central boiler use for fuel?
Do you have a conventional heating system in case you have to leave town for a week?
Is there an affordable wood gasification unit that runs on wood chips producing bio char and use able bio diesel onsite? Amaron oil makes a commercial unit. Great work.
What about a bypass with a blending valve around the Ice tank? That would provide a way to get the temperature you want to the load
now you have to use that same flowing water in the same system and use a filtering device so that you can tint continually use it for washing your hands and dishes and so forth. not to mention using solar energy to power the fans that cool your house. what's the most natural method to heat your house in the most economically sound away?
Interesting project. I am curious to see actual temp and humidity data after it's operational.
looking forward to it
What kind of water chiller did you use
I understand what you meant to say by no more refrigerant but water/glycol is technically a refrigerant
If the system can't handle the humidity fast enough remember you can cheat and just add plates to pass cold water thru to collect condensation on and have it separate from the temperature control.
When did you go to RPI?
what is the cost to convert the house into water cooling and heating?What
very extremely cool
what are the dangers of contaminating the water table
any update to this?
great vid
we had this system in 70's in our apartment complex in IRAN!!
all it exactly same system water was getting cool central chiller or central commercial water heater!!,you just switch the source in winter or summer!!
you call it anything you want, but there is nothing new here
I've been unsuccessful looking for links to:
coffee with caleffi and Siggy?
Since you like them, I'd like to check them out. Could you put their links in the description box? Love your channel!
ruclips.net/channel/UC4zei-UZ7fi_43jvkS3rexQ
Sorry.
The link is not opening
I just tried it again and it opens right up?
Same here, the link won't work.
I was able to find caleffi, but not siggy....I got the impression that John had a channel on RUclips and/or a blog and/or website of some sort with resources that I could absorb into my eyeballs and then my brain.
This idea is really cool, but make sure you still get fresh air in the house somehow. While I don't imagine you suffocating, I can imagine it becoming unpleasant if nothing is done.
Don't the control valves go on the outlet side of the coils?
Yessir!
any updates?
Cool
Solar is the only way that is even remotely cost effective. There are conventional chiller based 'ac' systems in 2 high rise buildings I help take care of (on the magnitude of 20+40 ton compressors) They just don't cut the mustard on the 90+ degree days. The chiller unit makes the water plenty cold, but the blowers in the apartments just don't pull enough moisture out of the air.
is this because refrigerant is cooler and therefore condenses more moisture from the air that's circulating throughout the house?
Have you looked at using an absorption cycle chiller utilizing solar thermal collection rather than PV to a compressor?
Any advice / thoughts on where I could go for good info on doing this?
(Thanks for all the great vids!)
Missing your old style videos man, Get a go pro head strap and just take us to the project with you! Editing sucks I know :(
Trying to do both. Appreciate the feedback!
Tinker time mechanical engineers like to play with chilled water loops.Electricity rates for residential are not time specific. a VRF system with inverter compressor beats chilled water for home cooling. It's quick acting, no mass storage required, no extra heat exchange, pumps.
👍
Let’s go.

holy cow. Your Alma Mater is $70k a year.
A bit pricey isn't it. I am very thankful I escaped with only owing 25k when I graduated! I stayed to get my Masters degree and it felt like I was winning since I got a tuition waiver and got paid teaching the robotics portion of a manufacturing lab class!
It would be cheaper to send my boy to The Citadel (my Alma Mater) for an engineering degree. Of course The Citadel's engineering program isn't rated as high or have mechanical engineering. Just civil and electrical.
Can't hear it.....
Nice idea hope it works for you
why not just buy a centralized air conditioner?
Uh, that thing already has bent fins. You need to be more careful. Bent fins = reduced efficiency and reduced cooling.

Could you please do me a favour and have a look at "the real Martian" RUclips channel he is needing some good support on a geothermal / hydronic heating and cooling system and I'd love to see a collaboration of two like minded Christians ☺️
Volume sucks,how long you guys been making suck videos?
