# Geo-thermal Cooling loop - Page 4

I don't think you can bury a pump, it must be accessible, maybe somewhere in your utility room?

Rule of thumb for a single pipe buried horizontal 5ft deep is 350 to 500 feet/ton. Convert that into Watts and invert it, and it's between 7 and 10 Watts/ft of pipe.

If we assume you want ballpark 600W cooling, you'll need 60ft to 85ft of buried pipe.

Just ballpark figures, I haven't really done any calculations, just using rules of thumb so you can see if it's feasible for you.

I'm horrible with math, do you have the actual calculation so I can plug numbers into it? Thanks!

EDIT:
Also,
For now I'm just burying the pipe since that must be done before concrete is poured. I'll worry about the pump afterwards.

Just a thought (from someone who has only just dipped a toe computer into the world of watercooling) but would it be better to have something like a septic tank as part of the geo-loop, then just get the watercooling loops to circulate within that to allow the individual loops to remain separated..?

That would be kinda like (but for a slightly different hazard level!) what they do for the cooling on nuclear reactors....roughly like this:

In this pic, the "Reactor Core" would be a closed cooling loop for/from each computer...

Perhaps, however my thought is that the tank would actually help to retain heat rather than transfer it into the surrounding ground area. BUT this is just a guess as I have zero hands-on experience.

Thanks for the suggestion!

I think it would do both.

In the winter it would retain heat more and in the summer it would retain a cooler temp, just because of the nature of the project.

As for pumps, we have a Grundfos pump on our "water-cooled" fireplace. They make a lot of different sizes and models. We are going to replace our pump next year with this one. And have the other one setup as backup, just to make sure we never have a failure when we have a fire running. Because that would be bad.

Here is the Grundfos website, which is kinda hard to navigate. I have a Brochure from them and it makes it all much more simple. It also discusses different heat/cooling methods. You may wanna have them send you one, for free, if you have enough time.

EDIT: if you can keep your computer setup close to the ground where you are going to have the Geo setup, you can use a pump with little head pressure. Which would make it either more efficient, or faster GPM. But if you have to move it to the second floor, then you will need more head pressure.

And you also need to calculate for the resistance in the piping, and everything else. Or you can just be lazy and get a big powerful pump, but it would consume more electric.

I agree with goodtobeking, Taco makes good circulators too, but I'm using Grundfos.

2nd floor doesn't matter all that much, it is additional tubing length, but the head you 'would' lose pumping up is regained when the tubing runs back down to the same level. It's the rho*g*h term in Bernoulli's law.

I'm getting the impression you want to run the coolant through the blocks and into the ground loop? i.e. no heat exchange to a brine that would run in the ground? Probably feasible, pump should probably be at the lowest spot possible to prevent cavitation, like right above the basement slab.

You should also find a way to use jet pumps into your system somewhere 'cause they're cool.

Thanks! I'd like to use as little electricity as possible, but I'd rather have it be effective over efficient!

What pump would you recommend?

I'll be putting the pump on the concrete floor right next to the pipe coming out of the ground.

Could you do some legwork and estimate the restriction of everything in your loop?

I could take a swag at a suitable pump if you tell me what flow you want and your restriction. Nice thing about Grundfos is the older ones are three speeds, newer pumps are variable flow with many different control strategies.

I have an idea....

what about using your french drain in your new house as the starting pit and going down from there? Then you can change your coil anytime you want. since you really wont need much of coil loop for a computer cooler.

Plus it might make the wife alittle happier hahahaha
