So OP, do you have a wife?

If so, how did you convince her to do it?

If not, I see why no one has stopped you.

I LIKE IT!

Because it costs less than my current pumps, radiators, fans, did and will knock about 5 degrees celsius off my summer temps silently.

Obviously not. I'm surprised it took so long for this question to pop up!

If I did, I think every dime of this would've gone to purchasing a mini-split hvac system instead. Brrrrrr, it's cold in here.

The funniest part about this question, is that I've been thinking it since your first post.

Hahahaha it crossed my mind from time to time.

LAWL. You know, you could run that loop thru some rads in your house to claim some of the geothermal HEAT instead of dumping heat down there. ;-) (Eh, this will work with your inline rad whether the computer is running or not.)

Oh, oh, idea, idea!! You could get a USB-triggered (or current-triggered) switch that starts the pump when your system is on... eh, nix that... I wouldn't waste the time/effort/resources.

It's such low grade heat that it doesn't seem usable without a heat pump.

A 1-wire magnetic current sensor combined with an X10 switch could be scripted to remotely trigger the pump as well.

Getting a minutely dew point calculation that would power on a dehumidifier at a specified threshold is my highest priority for the monitoring system. That's the most practical part of constantly measuring the water in, room ambient air, and humidity. Having a low power, silent, lightly chilled loop that's mostly worry free would be nice.

I can't believe I just skimmed this whole thread, but I did. This is so cool. Can't wait to see how it works!

Thanks! The best is yet to come. I'm trying to get this finished by the end of the next weekend, but the supply/return piping insulation might hold me up.


Today's update:

Not having any 45 degree angles kept me from finishing the crawl space plumbing today. The existing plumbing below the utility closet and the lack of crawl space the other way ruined my plan of only using one 90 degree angle.

That meant another trip to Lowe's tonight where I picked up a 10 pack and some more lengths of the 3/8th wall pipe insulation. I'm going to go ahead and use it for all of the pipes under the house. I just want to get it over with. 95% of the piping down there is AFTER the PC section of the loop so the ground should equalize the ambient gains or losses. It's also possible to add another layer of insulation down the road if necessary.

Working with one foot of clearance under the utility closet proved challenging with the power drill. With the screw its also about 1cm shorter than the space between the joists. My advice would be: use small tools, start at the hardest area first, and then work away from there.

That would've saved me time. Don't work in a open crawl space on a day with strong gusts either. Sand blasts to the face.

I'm not sure how I'll bring in the 3 sensors wired to cat5e cables yet. I'd also like to wire a 24 port switch in the utility closet as well. So a more forward looking solution for many network cables would be nice.





The house section of the loop will be operational tomorrow. While leak testing I'll further coil the geothermal piping. Once that's done, I can connect it and check the flow with it above the ground. Seeing the flow rate loss upon adding a few spare waterblocks would be interesting if nothing else. They're going to add quite a bit of restriction to the estimated 4gpm flow.

The hobby boards 1-wire order will ship Monday, which means I'll have the ground moisture sensor mid-week. It'll probably read 100% all of the time so I'm considering tethering it to the bottom of a ten foot iron pipe that could be extracted later.

The excavator's current work project will also be finished mid-week. I'm feeling pessimistic on the chances of receiving the R4 pipe insulation next week though. It's getting more tempting by the day to spend more and source it elsewhere.

Looks good man 24 port network switch mmmmmmm, I think you need to get a small PC and run Untangle on it so you can go networking crazy, then you can get a few pipes to the closet and liquid cool your mini pc (now a router) too!

A 16 would be enough but the 24s aren't that much more and have trunking possibilities! I have an embedded alix box running pfsense for those duties.

It bridges two wireless 54g CPEs to the two business offices here so I can perform (slightly) off site backups.
