I have been follow this guide https://github.com/ccutrer/waterfurnace_aurora to connect to the AWL unit and start pulling data points from the unit. I have followed the guide multiple times.

I have a brand new WF7 unit with AWL. As soon as I connect the cable into the AWL the unit shuts down. Checking the fuse, it is blown every time. I have followed the instructions and re-made the cable using the T568-B specs. I am also using the same USB adapter that is in the readme file. I have confirmed on both ends the pinouts. I taped the wires that are not being used to ensure they are not touching anything. I also made a brand new cable from a different cable. The adapter is not connected to anything when plugging in and is not touching anything.

I would like to extract the data so I can put it into a database and use it in Garfana with the other data sources I have for my home.

Thoughts?

Hi, I was tasked with figuring out what’s going on with a geothermal HVAC system that’s not keeping up this summer. Closed loop system, you can kinda see the horizontal lines where the pipes are buried in the yard.

It’s a split system for ~2800sqft home, 2012 series 7.

The first company that came out gave this info:

water inlet: 20psi Water outlet: 18psi

System has a e15 and e57 fault stored in history

Supply temp: 51.6 Return temp: 69.9 Delta T: 18.3* Outlet: 103.5* Inlet: 96.2* Delta T: 7.6

—> E7 - stopped up condensate line. They cleared the condensate line and poured a gallon of water to make sure it was fixed.

Then another company came, because that one recommended replacing the entire water heater system or whatever and they said:

Main floor system: good Upstairs system: 0psi

Then they did a pressurization test and came back a week later - held at 20psi.

They wanted to do a water flush, but we did not do that.

So questions: Why does it matter if there is no water in the line if the system works without it?

Is the line supposed to be empty?

And any guidance on how to figure out what to do to make sure the system is able to keep up.

EDIT: I’ve been tasked with figuring this out and have little to no knowledge (aside from a few deep dives googling, so any and all guidance is so appreciated - thank you for those who have helped so far and thank you for patience and grace since I’m a total noob tryna figure this out for my employer)

Hi group,

I want to construct a geothermal system driving by air in contcat with the ground in my house (argentina) like canadiam holes. Summer about 35°C, winter about 5° to 10°C.

How can I know the properties of the Group to know the K of the soil. Is there any soil study regarding the type of soil? Just to see the deep and the length of the pipe that should be in contcat with the soil.

Kind regards,

Hello. I have an open loop geothermal system on my property. It supplies a heat pump and the entire house.

I've noticed the pump, a Grundfos SQE, runs non-stop. It's also connected to a Grundfos CU301 but this unit is not controlling the pressure. Its led lights are off and doesn't respond to any interaction. It's just there doing nothing, allowing the water to flow freely

The rest of the system includes a tank pressure, and the water sensor.

I suppose, at some point, it was disabled and let it run continuously? Or Grundfos failed and water keeps flowing?

I'd like to see if it makes sense trying to leave these systems as they were supposed to be and understand why they are now this way because that was done in the past by previous owners.

All your advice is greatly appreciated 🙏

I got two quotes for adding geothermal to my home. Both of them quote a package unit for downstairs and a split unit for the attic.

One of them quoted a single ground loop shared by both units, and the other quoted separate loops for each unit. Both quoted three boreholes, 400' each. These would be vertical closed loops.

When I asked about the split loop, they said it's for redundancy: If one of the loops fails, there's still a backup. I like redundancy, but at the same time, I'm worried that the unit with one borehole might saturate while the two boreholes for the other unit are underutilized.

• What do you think about this design choice?

• Is it practical to bring all three loops into the basement, and reconfigure how they connect to the units in case the initial arrangement doesn't work?

• Does it make sense to get four boreholes so the capacity is even between the two units?

Thanks.

Hello, we're World Geothermal Energy Day!!

Once a year we celebrate on October 17th. Normally, selecting a date for an event is an easy task; the first nuclear power reaction (Fermi Chicago Pile - 1942), the first computer (ENIAC - 1946), and the first satellite launch into space (Sputnik - 1957). Selecting a unique date for the inception of geothermal energy is an impossible task. However, we've selected a date in the annals of high impact thermal events; the explosive eruption of Mt. Vesuvius and the impact it had on the innocent people of Pompeii. Most all of us first learned about this event while in elementary school or high school, and it still brings attention and interest to adults around the world. This event still resonates with us all. While the actual date is still in dispute, we've selected the provocative new date of October 17 in 79 AD; nearly two thousand years ago!   

This is the one day when people around the globe celebrate the virtues and benefits of geothermal, open their shops for tours (both virtual and physical), discuss new technologies, and work to include geothermal in legislation at the local, regional, national and international levels.

Harnessing the energy of the Earth's interior for heating falls under the name of heat generation? Is it possible to calculate the temperature of the Earth's layers within the sphere temperature distribution equation? Is it possible to consider that the Earth's layers have Constant thermal conductivity?

Currently have two Trane units in my 4500 square foot home 3 ton for upstairs and 4 ton for main level and basement. AC units outside. 4 ton is a heat pump outside and furnace is gas a backup ie dual fuel. upstairs unit is straight ac and gas furnace in attic. Both systems are about 16 years so replacement time is coming sooner than I would like

Requested current hvac company to quote replacement for two dual fuel systems with heatpump/gas furnaces. Asked for both 20 and 17 seer Estimates. No numbers yet

Asked local geothermal company the day after I asked for above ref quote. Geo company quoted in two days.

This is what they are proposing

2 series 5 split units NDV 049 / NDZ38

2 flow center FC-GL / FC1-GL

2 AUX heat unit 15 kw /unit 10 kw

2 sound insulation pads

2 connection hose and insulation kit CK4LI (series 5)

2 symphony aurora web link/wifi

2 intelisoft soft start control

2 Aurora advanced control w/ performance & refrig package

2 variale speed eco blowers

3 x 375’ vertical wells with HDPE ground loop pipe

all permits, duct work (if needed) and return all landscaping/yard back to original condition

also remove all current ac/heat equipment

very professional communications. I asked for update to quote for series 7 to compare.

total quote series 5 units installed is $82,265. Less tax credits of $24,680.

I'm just getting started on this.

My last two ac bills were $450 and $350.

wondered what you guys that know think about this proposed system and quote. Reasonable?

Can anyone share your experience with loans and rebates available in PA for installing Geothermal Heat Pumps. I am replacing my current Geothermal unit

Seems my Waterfurnace unit missed the optidri by a couple months, and my house is having humidity issues.

Any way to retrofit the optidri system to the 7 series?

Has anybody installed one of these units in the US? Anybody around the gulf coast?

Looking for a position to sell geothermal - have over 15 years with in home sales experience. Looking for a job in the Greenville, SC area or companies who sell it. Thanks

We had our vertical loop and split geothermal system installed 16 years ago. Which for our area (Cincinnati Ohio), was very early. I fear that we were experimental. We have had 16 years of continued problems. Our current observation is that our incoming water from the loop is 107 degrees f. Unfortunately our loop is under our driveway. Any thoughts?

I’m posting for a friend, so I have limited information, apologies in advance. He told me that he cannot adjust the temperature up or down more than 1 or 2 degrees in a 24 hour period or the breaker for the system will trip.

This does not sound like normal behavior to me and seems like an issue with the electrical or units themselves. Any thoughts?

I'm frustrated. I have a rural property where I'd like to put in geothermal but am having a terrible time finding a contractor. I've already called the six places within 70 miles: five won't call me back and the 6th quoted a $120k system, told me it was a ridiculous price so he wouldn't do it, and then ignored me when I tried to ask what was causing the pricing problem.

Maybe I'm asking for the wrong thing? Or maybe geothermal is not the answer to my situation? Can you help me identify the problem with my ask? Here's the information I have ready to share about my project:

1. The property is in southern MN with 7 months of heating and less than 1 month of cooling. Humidity is 60/70% in the summer and 70/80% in the winter. It's at 44° N with 30-60% cloud cover which is why I'm favoring geothermal over solar thermal, but I'm interested in both.
2. My goal is to use renewable energy as passively/simply as possible for seasonal climate management.
3. I have a 200' x 200' area for a horizontal loop (I want to clear/regrade it anyway). My understanding is that this is enough space but that horizontal loops are less common (despite being easier/cheaper).
4. I have a 2000 sq ft basement, 10' below ground. I have a 2000 sq ft apartment, 6' above ground. Ideally, I'd want to heat/cool both, but primarily upstairs, with hydronic radiant floors.
5. I am planning a 16' x 100' passive solar building containing an 1800 gallon pond.
6. I want to keep the house and pond between 70 and 80° year-round.
7. The main building is under renovation and the pond/building do not exist yet. I can say plenty more about both as needed to calculate heating load.

So far, I have searched for "geothermal" and "HVAC" to find contractors in the area. I also searched for members of the MN Geothermal Heat Pump Assn. When I contact prospectives, I give my location and say that I'm interested in a horizontal geothermal system for my house and pond.

Is my project reasonable? Is there a better way to find a contractor? And/or a better way to introduce my project to them? Got a better idea I should be looking into?

Thanks for your help.

Can you tell by looking at this photo what kind of ground loop I have?

I am having a deck built and footings screwed into the ground. Forgot about the possibility of the geothermal pipes being hit by the footings…

Hello. I just moved to a house and it has this geothermal unit https://ibb.co/Vjz8RHX

I've noticed that the fan never stops. It has been running 7x24 no matter the thermostat is off.

I don't think it should work that way but it's the first time I have one of this units.

I appreciate your comments.

Hi all! Geologist here. I’m interested in learning more about geothermal energy/heating. Are there any books or resources you recommend to get started? Thanks!
