Geothermal Maintenance 101 - Heat of extraction / rejection
Вставка
- Опубліковано 16 жов 2023
- The first thing a geothermal maintenance technician should is how to complete heat of extraction / rejection. This test will allow you to properly confirm that a geothermal system is performing properly. With this simple process you can confirm that the system is running at peak performance during a maintenance while also preserving the systems life by not introducing contaminants to the refrigeration system.

Excellent! Thankyou
Good to watch content from someone who it's obviously passionate about HVAC.
Brilliant! Should be required viewing for any geothermal tech. Hell, any geothermal owner.
Been looking for a channel like this! I myself own a 7 series, so this is perfect content to help me understand my system much better, thank you!
Man, Thank you so much for taking the time to make these videos. My father and I installed geothermal at their home up in VA but I mostly just dug the loop system. He passed away unexpectedly last year and I’ve been super intimidated about tending to it. That guy did everything.
We’re from Charleston SC! Thanks again
Keep the great content coming Andrew! We really appreciate it
Great video. Definitely want to see more Geo content.
Oh I'm totally putting a bottle if astroglide in my bosses geo kit!
By the way thank you for making this and I'm so glad I found it. I've been working on these things for a little over 3 years, and have a pretty good handle on how they work and how to service/diagnose them. However, I've never had this properly explained to me yet. Thank you! More water furnace vids please!
Flavoured too for her pleasure

Thank you
Great info
My 1st house brought it with it
So you would need those calcutaions. If you're doing a repair. Or when setting up the unit. But not for maintenance. Is there really anything that you need to do for maintenance. Other than check the water for ph balance and antifreeze values. And filter on a water to air. Which should be changed out regularly. By the home owner.
Basically no maintenance ?
Thank you very much! You answered a question for which I couldn't get a clear answer, temperature IN was 77 so if you are a 68 degree guy, this type of system is not for you. A traditional air to air would be more appropriate for that type of person.
Negative, water temperature in has nothing to do with the temperature that the system can deliver to the house. There are plenty of houses with geothermal that can achieve 68°. On a "Air to air" system the "tempurature in" on a 95 degree day is 95° for example (when measuring at the condenser coil which is comparable to the water in on a geo). Let me know if I am misinterpreting what you are saying.
Do you have any videos on how to troubleshoot water to air geothermal heat pumps
When it comes time to replace the inside unit, what is the average cost? Thank you!
Hello! To ready the unit can I put it in heat mode vs cool with the fan on high?
Yes, that would calculate "heat of extraction".
👍🏿
Assuming all would be the same for a non-pressurized system as long as you know the gpm?
Correct but you can also calculate the GPM the same way as long as there are P/T ports at the unit
Was the second needle part of the Testo 549i or an add on?
It was an add on. I linked the needle used below. You will have to adapt this using a brass fitting you can find at a hardware store.
