DX geothermal, direct exchange geothermal. What is it and what are the pros and cons of direct exchange compared to regular geothermal systems? That’s what we’ll cover in this video. I recently got an email inquiry about DX geothermal, direct exchange geothermal: "...We are struggling to decided between an ASHP system and DX geothermal system for a retrofit. ..." I dug deeper and this is what I found. We'll discuss the pros and cons of using copper with a refrigerant vs. the regular water wells with common HDPE, high density polyethylene. Enjoy!

This is a re-upload of the DX geothermal video that I published six months ago with a few minor fixes. The messages are still the same. So, if you have already seen it, feel free to ignore it and wait for the next new video. My apologies for any inconveniences. If you are new to the channel, I hope that my videos have improved over time... So the newer ones should have a higher quality and hopefully higher value for you... I'm always curious what I can improve on, whether that's subjects covered, audio/video quality, B-roll, or anything else. Thank you, Katha

I had an interview yesterday and the DX heat pump with a horizontal exchanger was proposed. I was also very surprised that the scientists, manufacturer and service are from my city in Poland.

Interesting. The installer is the most important factor in any heat pump installation. Hope things go well for you.

Geothermal is really interesting tech; have you ever thought of doing a video on it’s application for district heating in a city?

@NetZeroTech 3 месяца назад

Hi Daniel, I think some of my videos include or touch upon district heating, like this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qirIXHU4KIU.html I put it on the list of ideas for future videos, though. Thank you! 🙏

Dedicated coper tubes are coated with a thin layer of plastic like polyphenol to prevent corrosion and the price is lower than copper tubes.

@NetZeroTech 3 месяца назад

Agreed. Thank you for sharing!

Glycol you've mentioned as a harmless, is what you car engine coolant made of. On the coolant container you can read warning on how much 'harmless' it is.

@NetZeroTech 3 месяца назад

Apologies, if I didn't specify sufficiently. I probably meant less harmful than some of the other refrigerants. Would you like me to trim that section? Thank you for the feedback, 🙏 Katha
