Hey, I’m working on a ClimateMaster water source heat pump. The unit keeps frying the DXM2 control board. When I first looked at the unit there weren’t any lights on the control board. No green led or red fault light. I checked to to see if the board had 24 volts, it did. I figured it had a bad board. I installed a new board. When I applied power it instantly killed the new board. The same thing no lights nothing. Any help would be appreciated.

If we have low superheat AND low subcooling, what does that signify?

Useless.

When you backfill, should you keep the soil moist, maybe like mud, to get the maximum surface contact. Is backfilling with sand a good idea ?

Great video. However I needed to hear about geothermal heat pump pond loops in a cooling dominant climate. It’s also a heating area in mountains of southern New Mexico so both cycles would be used. But more cooking load than heating load. How do I calculate the system? Is there a website that has charts. Thanks

Need to make it cheaper and more efficient to extract heat from earth

How do you change your pin

My nephew had one of these put in his new house when he built it. It keeps the house 72 degrees in the hot Texas 105F heat. You need about 1/2 acre of land to lay out the pipes. I don't know how the return on investment would be on such a unit.

There is an easier, more useful, and better way than digging all of this just for the sake of extending pipes, and it can be used anywhere on the ground under special conditions according to each region, but the idea needs support from anyone whom I might make a partner in this innovation.

Thank you for a very informative video, could you please help me with pipe sizing and let me know if I am trying to replace 2 Spit System heat pumps, one (4 ton and one 3 ton) with Geothermal, can I use 1 loop for both units or does each unit need its own loop? These are my conditions: Large Lake 75 miles long) Lake is 175ft away from house down hill with 10ft of water under the floating dock - elevation from house to Lake is 15ft below house - planning on a closed loop system built on a PVC skid with Blocks underneath - Location Upstate SC - Lake never Freezes - I would like to only trench in 2 lines to the house to feed both units, but If I need separate loops for each unit that will be 4 lines up from lake. I was planning on 2500ft of 3/4 HDPE for the Loops and 3/4" HDPE To feed the Loops from House?

Heating water requires expensive energy which be a great energy draw. Having the assist of earth heated water is a boon. After Geothermal is installed a backup of solar energy to provide for the clothes dryer there and lights (pc and phone charging) makes sense.

You can check each phase of the motor at the connector for the motor at the control module with a DMM. Each phase should have a resistance that is less than 20 ohms and they all should be relatively close to one another. Also check the continuity of each phase with respect to the motor casing. Each phase should read O.L. or infinite meaning that there are no shorts in the motor winding to the metal casing of the motor. Finally, it's the control module (bell end) that usually fails and not the motor itself.

I wish north Texas HVAC companies would embrace this technology . I moved into a house built in 1963 some 30 years ago . I put the best windows and a white metal roof on but nobody would install geothermal. Now I can't afford it !

Thanks new air filter cured it

The compressors that was used in my geo unit had problems from the beginning

HDPE is slippery, maybe too much for the taste of barnacles.

I've been running open loop for 32 years. Love it, but on my second WaterFunace.

Not sure why the seller of a water source heat pump brand would stick all of these warnings into a video to SELL a system......trust me, it's not complicated at all. If you have a water well without high mineral content, you're good to go. If you do have mineral issues, isolate the heat pump heat exchanger with an external brazed plate heat exchanger.....if it becomes problematic, it's easy to clean or replace. You DO NOT need to bore a separate well for the discharge water. If you live in sandy soil, just dig a hole and plumb the discharge to it. I used a 30 gallon barrel dug into the ground, and it works flawlessly ( I never said there'd be no work involved..) If you're in tight soil (clayish....) you will have to be creative. If there's a ditch nearby, do that. The building inspector I dealt with didn't care less...(nothing in the code specifically for spent water....) THE MAIN TAKEAWAY from this video is showing the MAJOR flaw in air source heat pumps. When an air source heat pump gets into the lower 30's it has to defrost the coils (and even warmer in some conditions..) and THAT is how heat pumps got a bad reputation....massive electrical resistance coils energize (think hair dryer...) and man, the electric meter spins like you wouldn't believe!!! Does not happen with these units, unless the system faults. You are required to have that back-up in emergency situations. Don't let all of this techno gibberish make you shy away from this EASY tech....I have two, and they both perform flawlessly...to the point (and this is funny. Duke Energy has replace my electric meter THREE times because they were convinced from an audit, that I had to be cheating.....I'm not!! It really is that good!!

Thank Yiu!

How exactly do you adjust the blower cfm? I have the thermostat mounted on the wall, but the option to adjust the blower is not there? Do I pull it off the wall and plug it in somewhere behind the panel?

I have the Climatemaster tranquility 27...I highly suspect my installer plumbed my hot water heater wrong. I have looked my owners manual over and it really doesn't show anything on that. Is there someone that could help me? They have the domestic cold water supply piped into the DWH out, and the DWH in goes to my bottom drain inlet on the water heater. I don't think that's right or is it?

So why does mine say this even with the correct info?

We have both a gas furnace (emergency heat) and a conventional heat pump. I'm finding out that at about 40 degrees and below it is more economical to heat the home with the gas furnace. The heat pump doesn't deliver hot air through the ducting (warmed air, but not hot) and the spouse is happier when it is cold outside to have the gas furnace heating the home (happy wife. happy life!). Just sharing my experiences. Mine may be unique.

When the sun goes down all solar has a backup battery

Most houses have a water softener or a means to remove solids.

Nylon rots in water. Everyone who installs water well pumps know that. Have seen lot's of zip ties fall apart. Other than that, good info.

We just got a quote for this in Austria of 70,000-75,000 euros! Our lot would need the vertical system. This is out of reach financially.

This is a terrific presentation. Any idea how I'd find a heat exchanger? I went to the website and only see the cabinets.

Cost $30,000 to install a Geothermal unit in my house. The unit lasted 3 years before the pipes underground broke a leak. Found out a couple days ago that my unit is screwed until I dig up the pipes to find the leak. My house got the unit in 2019. There’s no compensation, I have to pay to fix it myself. It’s in the middle of summer, my house is currently 86 degrees. Great experience so far

Will this work in the tropics?

Interesting but home many years to recover the cost?

I get how this works but why aren't "vents" installed at high points? I had a "guy" come out, stuck his little needle in there, added about a cup which upped my pressure and left. The system is full of air and I want vents!!! I can easily add a fill valve. This system worked for 11 years before this came up and I'm not call'in the "guy" back.

Why people's don't choose this instead of ac.

Low Press Control is on the High Side of System is Used as a Loss of Charge Monitor or Control,,,,,,,when Unit shut off control should Close again but Unit will go on Hard Lock out Condition

Low Press condition

Are there batteries inside?

how do you test each of those possible faults?

Great explanation! Thank you

These systems will cost more than a traditional system, but what you have to factor into the equation is "How much will I spend to heat and cool my house?" So if you are building in Fairbanks, Alaska, where most of the heating is done via fossil fuels, you can cut the fuel bill to nothing. The kicker is you have to take out a loan that may add $100 a month to your mortgage. So its simple really. How much on average do I spend heating my house? If it is $200 a month, then you should have already done it.

good, i want to installed this system in a proposed 1 K house in islamabad Pakistan.

anyone can help to build up for my factory ..

Does evaporant cooling help with cooling in a spring fed pond?
